Accurate, complete, boat-specific and easily accessible technical information for vessels and boats not only enhances safety and accessibility, but also reduces the total lifecycle cost. SSPA has written a case study describing a recently finished S1000D project for the Swedish Defence Materiel Administration. The case study describes our work from start to finish, including pre-history, challenges, project lessons and visions for the future.
Knowing how a vessel will behave in certain conditions can help answer many questions, for example; What is the operational window for ship-to-ship transfer?, What size and number of tugs are needed for safe berthing? Will the vessel roll heavily in the forecasted weather? In what conditions can the ship be safely moored? What engine power is required to be on schedule 98% of the time? One way to address these types of questions is to use advanced simulations. At SSPA, we have developed a toolbox, called SEAMAN Simulation, which can provide a solution for the issues above and much more.
As a part of the FAMOS Odin research project, a route optimisation analysis was performed. SSPA presents the results of taking stored AIS tracks and optimising their route geometry as well as their speed to minimise fuel consumption, i.e. to minimise the shallow water resistance experienced by each ship. The results show key changes in traffic patterns, specifically fairway shortcuts that could be taken if there are no safety concerns.
A new research article is published in the journal Marine Policy. This paper provides an overview of how Automatic Identification System (AIS) can be used in different areas of maritime research. AIS data can be incorporated in various types of modelling approaches and play a small or large role as a source of data. AIS data can also be validated or used to validate research from other data sources. The researchers have identified and presents ten different research areas in which AIS is used today. In the future they propose making use of AIS data also in other research fields. Many stakeholders can benefit from the research in which AIS data is used.
The eight Conference on Computational Methods in Marine Engineering (Marine 2019) was recently hosted by Chalmers University of Technology in Gothenburg, Sweden. This conference is a meeting place for researchers developing computational methods and scientists and engineers focusing on challenging applications in marine engineering. Researchers from SSPA, together with some of our research partners, presented interesting papers.
It is not a trivial task for ship owners and shipyards to decide which coating to use or how often the surfaces should be recoated or cleaned based on cost/benefit analyses. SSPA has completed a research project with the aim to gain increased knowledge of the effect a rough surface has on skin friction. This project has also resulted in an interactive tool that can be used to estimate fuel consumption without requiring background knowledge in hydrodynamics. This tool is the “Skin Friction database”, which will hopefully contribute to better surface treatment of vessels, that in the end can reduce costs and emission of greenhouse gases from the maritime sector.
The paper “Comparison of modern keel types for sail boats” was published in late 2017. The study systematically evaluated the hydrodynamic performance of different types of bulb keels. Recently, the paper was awarded with two prizes at the Royal Institution of Naval Architects (RINA) annual meeting. The Institution’s Medal of Distinction and the Austin Farrar Prize.
Recently transport buyers, shipping companies, forwarders and researchers attended a workshop in Sweden to discuss barriers and opportunities for shifting goods from road transport to short sea shipping within Europe, and also environmental performance of sea transport. The workshop was organised by SSPA and partners as part of a research study. A project report concluding the research project will be available in August.
You do this by implementing S1000D, the International Specification for Technical Publications. SSPA supports the Swedish Defence Materiel Administration (FMV) in several projects with information analysis, data conversion, restructuring, content revisions, and quality assurance.
SSPA currently lead the ITTC Specialist Committee on Combined CFD/EFD Methods. CFD stands for Computations Fluid Dynamics and EFD stands for Experimental Fluid Dynamics, i.e. model testing. To facilitate the introduction of CFD/EFD Combined Methods in our community, the Committee has identified several research areas which need to be addressed. In this way, they wish to inspire researchers around the world to contribute to the development.
The latest issue of our company magazine, SSPA Highlights, issue 66 has been published. Read about; Skin Friction database, Route optimisation based on AIS tracks, Defining normal ship behaviour and safety distance, Logistical consequences of container port conflict, Implementing S1000D for military assault and support crafts, Thorough model testing required to make cruising in tough environments sustainable, The importance of high-quality data.
Transport activities can become more energy and cost efficient by improving the load factor, i.e. balancing the required and available capacity of transportation. Statistics about load factor are missing today, in particular for sea transports. There are unused opportunities to calculate load factor of ships by using innovative data collection techniques, enabled through digitalisation in terms of AIS (Automatic Identification System). SSPA’s experts has investigated how the load factor can be mapped from AIS-data and analysed the energy efficiency potential of an increased load factor in sea transports.
The Swedish maritime industry join forces to put together the best trainee programme for newly graduated Naval Architects. The trainee programme involves different actors in the Swedish maritime industry; shipowners, shipyards and manufacturers, classification societies, authorities, designers and more. The application for 2019/2020 opens 15 December 2018 and close 31 January 2019.
Knowledge-based organisations like SSPA constantly have to adapt to a changing world. At SSPA, all specialist engineers can be involved in research and development (R&D) in addition to the commercial work. This facilitates a two-way knowledge flow between research and business. The decentralised R&D-organisation does, however, require very clear management with defined goals, roadmaps and prioritisation. Our strategic research plans help us to set the direction and to break down the challenges into manageable goals.
It is a global issue with the plastics as marine pollution. Several initiatives have started around the world to influence people’s behaviour. In Sweden there is an awareness campaign called “Optimist för havet” (Optimist for the sea). Three Swedish organisations is behind the project and they all share the love for the sea. SSPA supports with building five prototype boats (optimist dinghies) from recycled plastic waste as a national flagship activity to raise awareness.
Recently, the STM Validation Final Conference was held at the headquarter of IMO in London. The conference lasted for two days and the interest was huge. We discussed how Sea Traffic Management affects safety, efficiency and the environment as well as how the industry is looking at digitization. SSPA’s experts was represented and took part in the demonstrations of the solutions in use and the early results of Route optimisation and Normal behaviour of ships.
The Swedish Maritime Administration (SMA) is responsible for the Swedish icebreaking service and has conducted a pre-study on how the current icebreakers can be replaced. SSPA has supported SMA with investigations of different aspects, including forecast of future tonnage in the Gulf of Bothnia, evaluation of alternative fuels, alternatives for hybrid solutions, evaluation of different propulsion concepts and overall feasibility studies of different options’ capabilities. The results of these analysis are tools for decision-making. To support the decisions in an economic perspective, the life cycle costs of different key features were assessed.
Sweden has decided to analyse the conditions for a switch to fossil free state-owned vessels. SSPA has under a frame work contract been awarded with the task to support the Swedish Transport Administration (STA, www.trafikverket.se) in this analyse and the development of a strategy on how governmental owned ships and boats can operate with lower or no emissions of fossil carbon dioxide.
Air lubrication systems are divided into three categories: air film, microbubbles and air cavity. In an article published in the International publication Ship&Offshore, issue 5/2018, we describe and discuss some practical aspects of each method. SSPA has been involved in numerous projects to develop and test different systems of air lubrication for decades. Our experts has carried out investigations on all these methods by performing tests, simulations and design consultation.
In a project together with Chalmers Sports & Technology, SSPA has contributed to the design and build of a racing skiff dinghy where 70 percent of the hull is made of biomaterials. The dinghy will soon compete in a three-day regatta against other boats representing universities all over the world. This dinghy is one of a kind. The sail plan is very large in relation to the boat, the mast height (9.5 m) is more than two times larger than the boat length (4.6 m), making it rather extreme. 70 percent of the hull is made of bio materials. The hull and deck are a sandwich construction with skins of flax fibre in a cashew-based epoxy matrix, and a core of balsa wood. The principles of skiff dinghy design have been combined with innovative, more environmentally friendly materials
As of September 3rd, Mr. Joacim Linder takes on the role of Head of Maritime Consulting. He will lead about 30 experts and consultants in three teams; Hull & Propulsion, Manoeuvring & Seakeeping, and Advisory. He is also a new member of SSPA's management team. Joacim has extensive experience in the maritime industry and has recently been responsible for the RoRo Competence Centre at Cargotec, MacGregor. He has an M.Sc. in Naval Architecture from Chalmers University of Technology.
Among all the factors on board that affect sleep and alertness, the impact of light may be less known. SSPA performed an overview, funded by the Swedish Mercantile Marine Foundation. With a greater insight about the effects of light; mariners can adapt new routines to improve their well-being. We can all benefit from knowing how to use light to maximise our performance, but it is even more important for mariners who are working and living 24 hours a day in a harsh environment where good recovery is important for safe operation and health.
The trend of reduced sailing speed, or slow-steaming, presents shippers with new, complex challenges. SSPA has together with Chalmers University of Technology and University of Gothenburg studied how the Swedish industry has met and managed these challenges. The study has recently been published in Journal of Shipping and Trade.
Have you ever reflected over the different types of bulbs chosen for yacht keels? Today there is no general agreement on which bulb type is preferred for different types of yachts and very little scientific investigation has been done in this area. SSPA and Chalmers have carried out a study, where the hydrodynamic performance of different types of bulb keels were systematically evaluated. A paper is published in the International Journal of Small Craft Technology (IJSCT), a RINA Publication
Sweden and Denmark has jointly developed actions to improve the shipping traffic in Kattegat and Skagerrak to be safer and more environmentally friendly. SSPA has supported the Swedish Transport Agency with comparative consequence analyses for the proposed new routing systems. The IMO Maritime Safety Committee (MSC) has now approved the proposal for new ship routes that will be in place from July 1, 2020.
SUMMETH, the Sustainable Marine Methanol project, which investigated and advanced development of methanol engine and fuel solutions for smaller ships, has recently been completed and the final reports are now available. The project concludes that methanol can be used efficiently as a combustion fuel for smaller vessels, resulting in significant environmental benefits. Particulate emissions are greatly reduced, there are no sulphur emissions, and large reductions in GHG emissions are possible if renewable methanol is used. SSPA was project manager and contributed work on environmental assessments, feasibility of sustainable methanol supply, and safety assessment.
Pollution in the ocean is also about the ambient noise closely related to maritime shipping and seismic exploration by the oil/gas industry. SSPA has been involved in numerous acoustic-related projects and continually developing various predictive tools, making them available to assist customers in solving problems related to underwater-radiated noise (URN). SSPAs experts are contributing with more research in this area. In August, a new paper will be published in the well-known journal Ocean Engineering.
Modern Finn dinghies are flexible in sections of the hull. The subjective perception of the sailors is that this makes the boat faster in waves. In a research project together with Chalmers Sports & Technology and Max Salminen, a two-time Swedish Olympic sailor and current World Champion, SSPA will attempt to verify this. We are now evaluating the tests that we have made with a modern Finn dinghy with a soft hull (Max Salminen’s own Olympic Finn dinghy) and a full-scale model built for previous rudder trials to represent a rigid hull. Can we verify that a soft hull makes the boat faster in waves? Is it possible for us to measure the hydrodynamic resistance between these two different hulls?
One of the research projects that our experts share knowledge in, is the EU-funded project EfficienSea2. Recently this project concluded the findings from three years of research of maritime digitalisation. The project has involved 32 European partners and has developed solutions such as the Maritime Connectivity Platform in order to create a more secure and seamless data exchange in the maritime world.
The GreenPilot Project final seminar, “Guiding the Way to Sustainable Shipping”, will be held 3rd May 2018 in Gothenburg, Sweden and all are welcome to attend. The seminar will include presentations of results from the project to convert a pilot boat to methanol operation, as well as presentations covering sustainable methanol production, safety and performance of methanol, and perspectives from ship operators regarding methanol operation.
The needs and possibilities of electrification within shipping is analysed in a pre-study, conducted as a Swedish collaborative project by Lighthouse, SSPA, Chalmers and RISE. This report is a synthesis of previous projects and interviews with actors within the shipping industry and closely related areas. The aim is to give an overview of the technical development within electrification of sea transportation and analyse parameters that influence the performance and costs of maritime electrification. The study also investigate the perspective of industry actors regarding their drivers for maritime electrification as well as existing challenges. Several project ideas has been formulated based on those insights.
There are multiple reasons for carrying out accident investigations, but the primary reason is often a need to gain a deeper understanding of the course of the events from both a human and technical perspective. From this analysis, conclusions can be made that may result in recommendations for decreasing the risk of a similar accidents occurring.
Legislation on the Energy Efficiency Design Index (EEDI) requires the determination of a “weather factor” – fw – reflecting the percentage of its calm-water speed that a ship can maintain in Beaufort 6 and corresponding waves. The higher the fw value, the smaller the speed loss and the better the ship will perform in a seaway. But how do we determine this unknown fw factor, and how do we strike a balance between accuracy and costs?
Manoeuvring performance generally features too late in the design process in SSPA’s experience. Sometimes shipyards have to face costly and time-consuming last-minute changes to the design (when the IMO standards for ship manoeuvrability are not met). And what if the manoeuvring performance is “too good”? Is the rudder too big? (Resulting in resistance that is too high). The use of a new method of CFD calculations enables SSPA to offer early-stage manoeuvring predictions with much higher accuracy than before.
MaRINET2, the Marine Renewables Infrastructure Network, is composed of 39 organisations who collaborate to progress offshore renewable energy technologies in Europe. It aims to accelerate the development of wave, tidal and offshore wind energy technologies and infrastructure by opening up access to 57 test facilities across 13 European countries. The project is now in its second iteration, and it is supported by the EU’s Horizon 2020 programme.
The Board of Directors at SSPA has decided to strengthen SSPA’s core business and to review the company strategy plan. As part of this process, the board has appointed Stefan Eliasson as acting CEO & President during the on-going recruitment of a new permanent CEO.
SSPA are working with projects on the development of innovative logistics solutions and energy efficient vessel concepts for increased use of sea transportation in general and inland waterway transportation in particular. Within this area, SSPA has a large role in two large collaborative Interreg projects, NÖKS II (ending in June 2018) and IWTS - Inland Waterway Transport Solutions (running until late 2020).
The Swedish maritime industry join forces to put together the best trainee programme for newly graduated Naval Architects. The trainee programme involves different actors in the Swedish maritime industry; shipowners, shipyards, manufacturers, classification societies, authorities and more. SSPA is one of the companies involved in this trainee programme. The application for 2018/2019 opens 15 December 2017 and close 31 January 2018.
The railway bridges in Stockholm city centre are to be replaced. Needless to say, this is a very sensitive operation and the Swedish Transport Administration wanted to acquire as much information about the problem as possible, as early as possible. One way of managing the impact of the operation on traffic was to transport and install the bridges over water.
It is a major infrastructure initiative to renew Sweden's icebreaker fleet. The Swedish Maritime Administration (SMA) has procured expertise from SSPA to support them with several investigations and the results are utilized in a prestudy. Our experts have conducted investigations and analyses within ten different areas in order to find answers of key issues and to support the decision-making process. In the prestudy, SMA concluded that the design of the first new icebreaker should begin shortly and by 2030 the five state-owned icebreakers, existing today will either be replaced or life-time extended.
Demonstrating new logistics solutions is shown to be an important step for gaining understanding of system prerequisites for commercialisation, both with regard to technical issues such as vessel design characteristics and cargohandling equipment, and social matters such as the importance of practitioner involvement and the evaluation of performance criteria.
If you are enrolled at a Swedish technical university and would like to carry out your master thesis project at SSPA, please send us an application before December 1, using the provided form. You can either propose your own project idea or select one of the projects that we suggest.
The conflict in APM Terminals in Port of Gothenburg has led to a large reduction in volumes handled in the port. We can observe consequences within the supply chain and large companies across the country stress the negative implications in terms of increased cost as well as problems of sending/receiving goods on time. SSPA and the University of Gothenburg (School of Business, Economics and Law), will jointly investigate the consequences of the conflict from a national perspective. This knowledge will benefit both authorities and industrial actors.
In early December, the trade show Marintec China will be held in Shanghai. SSPA has participated in the exhibition on a regular basis for several years and it is an opportunity for us to meet our clients and partners and to make connections with new maritime professionals. Come and meet us at the Swedish pavilion if you are visiting the trade show.
The maritime industry is currently experiencing a significant increase of interest in battery hybrid installations for new buildings and retrofits. The driving forces include the current development in battery technology, potential for lowering operational costs, increased capacity of drivetrain and reduction of greenhouse gas emissions.
The 20th Numerical Towing Tank Symposium (NuTTS 2017) successfully ended on 3 October in Wageningen, the Netherlands. This two-day’s symposium attracts experts, researchers and young Ph.D. students all over the world to meet together to disseminate the latest results, work in progress as well as encountered challenges. Two experts from SSPA participated with their knowledge on hydrodynamics and the new tool Virtual Captive Tests (VCT).
A new bridge is being built in the centre of Gothenburg, Sweden. The Swedish Transport Administration is investigating if a traffic management system can be useful to minimize conflicts between different modes of transportation. SSPA has supported this investigation and our experts has performed an extensive traffic analysis based on AIS and ship data. When using our database of AIS-data we have the capacity to map, describe and visualize traffic patterns on shipping lanes.
The International Towing Tank Conference (ITTC) has an important role as a cooperation platform for all towing tank organizations. It gives SSPA, as an active member, an opportunity to influence the worldwide shipping community. At the ITTC’s 28th Full Conference, the Seakeeping Committee presented a recommended procedure for determining "fw". The procedure is largely based on work by SSPA’s experts. After a suggestion from SSPA, the conference took the decision to start up a new Specialist Committee on Combined CFD/EFD Methods that will run at least during the next three years. The Chairman is one of SSPA’s experts.
There is a big potential in optimising the construction of ships by reducing weight and steel. Transports can become more energy efficient and reduce the environmental impact at sea. To find out more, a pre-study was conducted in 2016 and now a collaboration is established. SSPA together with Chalmers, KTH and Stena Teknik will conduct research on methods for dynamic ship dimensioning and the understanding of dynamic loads on ships will be able to enhance. During the project, a vessel model will be equipped to measure structural loads, model wave tests, and numerical calculations will be validated against model trials. Stena's concept vessel Stena Elektra is chosen as a model vessel.
The EU-funded JOULES project recently presented its final results at a conference in Hamburg. SSPA was a partner in the four-year project, which developed simulation and assessment tools that were used to develop ship designs for two future scenarios (2025 and 2050), with significant reductions of energy consumption and emissions of greenhouse gases and other air pollutants.
Port operators are experiencing pressure to improve operational efficiency and reduce costs. One option could be to implement Lean Production concepts and thereby working with continuous improvements. In a collaboration between SSPA and Chalmers University of Technology, Value Stream Mapping was applied to four different seaport container terminals of varying sizes. Several improvement areas were identified and the project provided the terminals with improvement proposals to increase their efficiency, including increasing the collaboration between actors and consider to automate certain processes in the handling of containers.
The maritime industry is currently experiencing an increased interest in electric powered vessels. The driving forces include the current development in battery technology, potential for lowering operational costs, increased capacity of drivetrain and reduction of greenhouse gas emissions. One of the crucial aspects is finding out when battery and hybrid propulsion is a feasible way of meeting the targets for a specific ship, including its operational profile. A number of recent projects shows that SSPA has the tools and knowledge to support our clients with answers to their questions and to evaluate different alternatives for propulsion, from batteries and fuel tanks to propellers. We will share our expertise in a seminar in Gothenburg on 30 August.
Prediction and analysis of added hydrodynamic resistance in waves is an established research topic, with several accepted methods, but the study of sail aerodynamics in waves is an open research area. The unsteady aerodynamic behavior of sails in waves can greatly influence the performance of a yacht, by providing increased driving force in some conditions, but decreased driving force in others. SSPA and Chalmers are cooperating in the Sports & Technology initiative, with several research projects in sailing. The leading journal Ocean Engineering has recently published a paper titled “CFD prediction of steady and unsteady upwind sail aerodynamics”.
High performance in sports are closely coupled to technology. SSPA and Chalmers University of Technology are cooperating in Sports & Technology, with several research projects in sailing. A team with researchers recently visited a conference in France to present their papers. About 100 researchers was gathered at one of the sailing world's major conferences. Results and findings from the research projects "The Foiling Optimist", “The Paper Boat” and “Ranking of 7 Rudders for the Finn Dinghy” was presented.
The Port of Helsinki has recently published a safety manual on Liquefied Natural Gas (LNG) bunkering procedures. The safety manual has been developed by SSPA in collaboration with the Port of Helsinki and the Finnish authorities. The safety manual outlines the safety regulations and demands that are required for safe handling in LNG bunkering operations, including ship-to-ship (STS) and truck-to-ship (TTS) operations within the operating area of the Port of Helsinki. The manual details the minimum requirements for shipping companies and LNG suppliers that wish to perform LNG bunkering at the port in a clear and practical manner.
Good vessel design will reduce the impact on the environment and have a positive effect on the financial life-cycle cost for the ship and its operators. This much is clear, but how do we achieve this? The answer lies in a correct interpretation and adaption to the operational profile for the trade or service intended for the vessel. But how do we ensure that this performance is attained? It is obvious that an icebreaker operating in the Port of Sabetta has different requirements for open-water performance than an ice-breaking LNG (liquefied natural gas) carrier operating to ports in Northern Europe or for polar research vessels or even exploration cruise vessels. They all operate in icy waters, but with different purposes and different operating profiles. What is most important, the consumption and emissions for a single design point or for the intended sea route?
Welcome to an international seminar on the 15th June, presenting the outcome and lessons learned. In order to reach the national target of fossil free transport by 2030, emissions reduction in the transport sector needs to accelerate on a technical and operational level. Several on-going and ground breaking projects are contributing to the development of different sustainability solutions.
The development of smart functions for shipping is revolutionising the industry. The trend is to use software to increase the efficiency, safety and environmental aspects of ships. SSPA is invited to speak at the Autonomous Ship Technology Symposium 2017, on 6 - 8 June in Amsterdam, the Netherlands. SSPA will present an open-source framework and show how it is used in the development of new functions for autonomous ships. At SSPA, we supports our clients with hydrodynamic knowledge and tools to make them able to test their smart future functions.
As of 1 June, Ph.D. Christian Finnsgård takes the role as Vice President, Head of SSPA Research. He succeeds Ph.D. Peter Grundevik who retires. Christian Finnsgård has been working as a senior researcher and project manager at SSPA since 2014, heading international and national research projects ranging from maritime logistics to sports research.
All merchant ships longer than 100 metres must fulfil the International Maritime Organization’s (IMO) standards for ship manoeuvrability. The best way to validate the criteria is model tests. Running model tests will avoid the risk of very unpleasant surprises during full-scale sea trials. The manoeuvring model tests are usually performed late in the design process. If the requirements are not fulfilled at this time, undesired design changes may be needed at the very end of a project.
The GreenPilot project has converted a pilot boat to methanol operation to show how a methanol conversion of a smaller vessel can be carried out in practice and to demonstrate the emissions reductions that can be achieved. The project began in March 2016 and the partners are ready to share their latest results. Project representatives will be attending the Nor-Shipping 2017 Exhibition, held May 30th to June 2nd in Oslo, to discuss the project. A project seminar will be held in Gothenburg, Sweden on June 15th, 2017. SSPA is committed to developing sustainable solutions for shipping, and we have dedicated experts who are excited to be part of this project team.
Widely used so-called energy efficiency indices and Key Performance Indicators (KPI) measure Carbon Dioxide (CO2) emissions and there is indeed a connection between energy and emissions, but the distinction should be made clear. In practice, energy efficiency refers to optimisation in hydrodynamics, technical solutions and operational profiles. The challenges of energy efficiency and reducing emissions have to be approached internationally and the International Maritime Organization (IMO) has focused on emissions and energy efficiency for a considerable time. An upcoming regulation is the European Union (EU) MRV Regulation 2015/757.
The consequences of global warming may reduce the need for icebreaking assistance in certain shipping areas, but will also open up for increased sea traffic and offshore activities in pristine Arctic areas. This situation provides opportunities to reduce the carbon footprint from maritime transport through reduced fuel consumption in sea areas such as the Gulf of Bothnia and the Gulf of Finland, and also through favourable conditions for transoceanic short cuts in the Northern Sea Route (NSR). But it also entails considerable environmental and safety risks that must be carefully assessed and controlled. SSPA is currently engaged in a number of client assignments and inter-disciplinary research projects related to oil-spill risk assessment and safe traffic management in ice-covered waters.
A demo for investigating the opportunities for using waterways in the city of Gothenburg has recently taken place in Sweden. The DenCity project is studying how waterways can become part of the city transport solution. Cities becomes denser, more people, more goods and more waste needs to be transported. The waterways are almost an untapped resource in Gothenburg. There is a great deal of space available for transporting goods and waste, and moving the transport to waterways would relieve the pressure on the roads and reduce both congestion and noise pollution. SSPA will evaluate how the use of the city waterways could be scaled up and become a commercial solution in the future.
Students and researchers from Chalmers Sports & Technology and SSPA, has together designed and developed an optimist dinghy with supreme capabilities. By using a composite with added graphene, the hull is made stronger. Hydrofoils are added to lift the boat, decreasing drag and allowing greater speeds. After tests performed in SSPA’s facility, the towing tank, the dinghy was ready to be tried out at sea. By this project, SSPA has increased the practical knowledge concerning the particular challenges of construction, configuration and testing of hydrofoil craft.
We are all aiming to avoid future economic surprises, to “think first” and to make wise decisions. But unfortunately, economic surprises sometimes arise. One of the main reasons for this is that when a new product or system is to be acquired, it is common to investigate only the cost for acquisition, with ownership costs frequently forgotten. Thus, just one part of the life-cycle cost is considered. This well-known problem is often visualised using the famous LCC iceberg, which shows that the acquisition cost is “merely the tip of the iceberg”, and that the ownership costs are hidden under the surface, e.g. cost for human resources, training, repair, upgrades and disposal; costs that constitute the largest part of the total life cycle cost in most scenarios.
During the spring, several projects are performing demo tests with the goal to develop the potential of inland waterways and city logistics in Sweden. SSPA is involved in several of these projects and our experts in logistics and shipping have knowledge to share. Waterways in urban areas have unused capacity which could be used for transport of people, goods and waste. An increased use of inland waterway transport and city logistics can reduce the strain on the road network with positive environmental effects such as less noise and lower emissions.
Under contract with DSME (Daewoo Shipbuilding and Marine Engineering Co. Ltd), SSPA has been testing and simulating the hydrodynamics of the new DSME 1400 AIP Class Submarine. SSPA performed the model testing on a scale model, manufactured and equipped with propeller, active aft control surfaces and forward hydroplanes.
The second Marine Renewables Infrastructure Network (MaRINET2) program has recently been launched and SSPA is a partner. The aim of the project is to facilitate research test infrastructures for actors in offshore renewable energy, free of charge. The European Commission Horizon 2020 program supports and finances the project that runs from 2017 to 2021. SSPA offers four major test facilities, Maritime Dynamics Laboratory, Towing Tank, Cavitation Tunnel and a Simulator, that are well suited for marine energy testing.
The Swedish Defence Materiel Administration (FMV) has procured SSPA to support with revision of technical information for CB90 (Stridsbåt 90H) and the support vessels LTRB (Lätt Trossbåt). The current technical information has become invalid and needs to be updated and modernised regarding content, layout and quality. Using the international documentation standard S1000D, SSPA will produce user-friendly electronic technical information customised specifically for each vessel. This project makes SSPA a part of raising quality and availability of technical information on-board, and part of making the amphibious systems safer and more available.
Ice-free waterways and harbors can be desirable during a greater portion of the year than what might be possible on behalf of nature. A possibility for suppressing ice formation at such locations can be the use of air bubbler systems. SSPA has just finished a project for STA Road Ferries (Färjerederiet) for proposing and comparing different design alternatives and pipe routes for an air bubbler system intended for a ferry route close to Östersund, Sweden.
The Swedish Defence Materiel Administration (FMV) has delivered updated combat boats, used in the amphibious battalion. The project includes in total 29 combat boats (CB90) that will acquire so called "lifetime extensions". Recently twelve CB90 was finalized and the remaining will be delivered during 2017. The goal is to increase the combat boats operational efficiency and technical availability. SSPA supports FMV with general technical support and expertise throughout this project.
The issue of speed is more complex for RoRo/RoPax vessels than other segments. A Swedish team with researchers from SSPA and the University of Gothenburg has addressed the preconditions for introducing slow steaming in Northern Europe and asked operators in Scandinavian waters how they prepared and have acted under SECA. An article about this study was recently published in HANSA International Maritime Journal.
Sea Traffic Management (STM) is an initiative to establish standardised information sharing with open interfaces. Now the STM Validation Project, which is a continuation of MONA LISA 2.0, starts to validate the Sea Traffic Management concept on 300 ships and in 13 ports, testing real-time information sharing to authorized parties in the maritime transport chain. A large part of the work relies on AIS data processed with the SSPA EGAC (enterprise GIS analytics cluster), which capacity has evolved dramatically during the last few years.
The Swedish maritime industry join forces to put together the best trainee programme for newly graduated Naval Architects. The trainee programme involves different actors in the Swedish maritime industry; shipowners, shipyards, manufacturers, classification societies, authorities and more. SSPA is one of the companies involved in this trainee programme.
Max Salminen, a two-time Swedish Olympic sailor, aims towards the Olympic games in Tokyo 2020. To prepare himself in the best possible way, he wants to find out what rudder is the best for him and his Finn. To find out, he teamed up with Chalmers Sports & Technology and SSPAs experts in hydrodynamics and sailing to test different existing rudders.
Interest in methanol as an alternative fuel for meeting emissions requirements continues to grow, and there are currently both a retrofit solution for a large Ro-Pax ferry and chemical tanker newbuilding projects underway. Methanol is also a good alternative for smaller ships operating on coastal and inland waterways, but has yet to be tested in these applications. SSPA is coordinator of the project, “Sustainable Marine Methanol” (SUMMETH), which is focused on developing methanol solutions for smaller vessels.
Chalmers, Sports & Technology and SSPA collaborates with several Swedish national team sailors and Olympic aspirants for Tokyo 2020. Some of the sailors are students at Chalmers and part of Riksidrottsuniversitet. In the Olympic classes athletes constantly strive to improve performance. To achieve this, they can either make changes on the dinghy or the way they sail. The hydrodynamic experts at SSPA performs different tests in the 260 metres long towing tank.
Currently there is a strong drive in the marine business sector to increase use of alternative fuels for propulsion, e.g. LNG fuelled ships. To supply alternative fuel, ship-to-ship operations play an important role, since it is the only way to transfer required bunker volumes for merchant ships in reasonable time, when terminal supply is restricted to less than a handful locations on an entire continent. Introducing an alternative fuel in large scale requires that the risks are evaluated in an efficient manner. SSPA is invited to present a paper on the Gas Fuelled Ships (GFS) Conference, taking place in Hamburg, 16-18 November. The paper “Simulator based risk management for LNG bunkering”, presents a tool for risk assessment, based on simulations, which is used for development and evaluations of equipment, ships, ports, operations and guidelines.
The development of the BB GREEN Air Supported Vessel has been ongoing for several years. Now, a demonstrator called “AiriEl” has been delivered from the shipyard in Riga to Stockholm for optimisation and sea trials. This Air Supported demo vessel utilizes electric propulsion and the aim is to reach a cruising speed of 25 knots. SSPA has been commissioned by Stockholm County Council to conduct and verify the model tests previously carried out by SSPA for the prototype. The goal is new fast ferries that enables rapid and environmentally friendly public transport in cities.
If looking on this issue from the perspective of a potential ship-to-ship LNG (Liquefied Natural Gas) bunker supplier or its client, the most important question is: - Under what circumstances and in which location is it possible to perform a ship-to-ship LNG bunkering operation with an acceptable risk level?
Lowering environmental impact, increasing comfort and control at sea, are effects and characteristics many ship owners and operators are searching for. The Danish shipyard Tuco Marine, in collaboration with Effect Ships International AS, Norway, has taken one step closer to these goals with an 18 metres carbon sandwich Air Supported Vessel (ASV) Soft Motion Demonstrator. The hull solutions has been tested and verified at SSPA.
The Ramform Titan launched a new class of seismic ship that is easily the most powerful and efficient in the world. They quickly recognized that the silent operations and wide stern made her perfect for seismic acquisition. The unique broad stern design and ultra-stable hull enables quick and safe deployment and the retrieval of massive volumes of towed seismic equipment.
The Swedish Maritime Administration (SMA) has procured SSPA to support them with technical expertise in a prestudy regarding a new fleet of icebreakers. The SMA is responsible for the Swedish icebreaking, and owns five icebreakers.
A recent article in the magazine Marine Propulsion & Auxiliary Machinery highlights the growing concern about environmental impact of ship noise emissions. Organisations such as IMO (MEPC), United States’ National Oceanic and Atmospheric Administration (NOAA) and EU (MFSD) are addressing the problem. This has lately been brought to wider public attention through articles published by national newspapers, e.g. The Guardian in the UK and The New York Times in the US.
Marine Propulsion & Auxiliary Machinery highlights SSPA as an example of companies that offer services to help maximise both energy and environmental efficiency: “In addition to offering services such as ship design and hydrodynamics, safety and risk management and alternative fuels, the company offers a portfolio of energy efficiency and environmental tools and services relating to underwater radiated noise.”
A seminar was held in Göteborg to introduce the recently initiated GreenPilot project and present the status of methanol as a marine fuel.
SSPA is a partner in the project, which has the goal of converting a pilot boat to methanol operation to show how a methanol conversion of a smaller vessel can be carried out in practice and to demonstrate the emissions reductions that can be achieved.
A study for the European Maritime Safety Agency (EMSA) on the use of methanol and ethanol as marine fuels has been completed by SSPA, together with sub-contractor Lloyds Register. The study evaluates the potential of these alternative fuels as solutions for shipping to meet more stringent emissions requirements.
The maritime industry is in the middle of a paradigm shift. It’s therefore with great pleasure that we like to announce that the Finnish Maritime Cluster project (FMC) signs a cooperation agreement with Zero Vision Tool (ZVT) to widen the use of the ZVT collaboration method for a safer and more environmentally, climate and energy efficient, while still profitable, transport at sea. A unique industry driven cross-border triple helix way to move forward together.

The International Maritime Organization (IMO) is responsible for regulation of international shipping, in particular to prevent from marine pollution. Next area to look into is the Wider Caribbean Region (Caribbean and the surrounding coasts), how can this area adapt to the same emission requirements as other Emission Control Areas (ECA), where the Baltic Sea region is an example. On behalf of the IMO and together with White Smoke, will SSPA conduct a LNG feasibility study, which in many ways is following the same structure as the one that SSPA and ÅF conducted for the Danish Maritime Authority in the the Baltic Sea region, but in a smaller scale. The most important aspect of the work is to identify barriers and enablers.
SSPA's has been working for The Swedish Contingencies Agency in the EnSaCo Oil Spill Project, an EU InterReg IV project. The assignment has been to generate material to harmonise a GIS tool which presents the environment sensibility for oil spill along the Baltic sea costs depending on season as well as looking into the avalable response resourses. A manual has been produced for how to plan, implement and evaluate such an oil spill response in the HELCOM area.
