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.

The latest issue of our company magazine, SSPA Highlights 65, has been published. Read about; Hull air lubrication: future and challenges, Assessing costs for new Swedish icebreakers: a 25-year perspective, The Nobel Prize and its implication for mariners’ health and performance, Maritime spatial planning and ship routeing systems, Strategic research plan for hydrodynamics, Ongoing hydrodynamic research project.

The goal of reducing fuel consumption, enforced by international regulations and high fuel costs, is motivating ship designers to investigate revolutionary ideas or re-visit old techniques and apply them using new technologies. Hull line optimisation and propulsion system improvements are common practice for achieving this goal, but what if we can eliminate resistance (at least partially) at its source.

Renewing Sweden’s icebreaker fleet is a major infrastructure initiative. The existing icebreakers have been in operation for almost 50 years and the new icebreakers are expected to have a similar lifetime. Operational costs for such a long lifetime have a huge impact on the vessels’ total life cycle costs. Based on a number of investigations of key features, SSPA has conducted life cycle cost assessment of a new Swedish icebreaker.

At SSPA, our specialists are involved in research and development in parallel with their commercial commitments. In this way, there is a direct link between R&D and commercial application. Four of our hydrodynamic experts will here present examples of ongoing hydrodynamic research projects intended to improve today’s methods in different areas.

The needs and possibilities of electrification within shipping is analysed in a pre-study, conducted in a Swedish collaborative project. 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. The study also investigate the perspective of industry actors regarding their drivers for maritime electrification as well as existing challenges.

Legislation on the 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? As a member of ITTC, SSPA is actively involved in developing guidelines.

SSPA assisted with an investigation of the tragic accident that occurred at the Port of Genoa, Italy in May 2013. A ship backed into a port control tower, causing it to collapse and killing nine people. By simulating the accident and running alternative scenarios, SSPA were able to give our clients thorough understanding of the events as well as important documentation to use in the legal process.
