Focus on energy efficiency
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. On the 1 January 2018, shipping companies will be required to monitor the CO2 emissions of their vessels per voyage for all voyages conducted into, between and out of EU ports.
SSPA has performed a study on behalf of the IMO, focusing on the optimisation of energy efficiency as part of the implementation of a Ship Energy Efficiency Management Plan (SEEMP). With decades of in-house experience on ship optimisation and a range of studies related to energy efficiency, SSPA has a vast knowledge of both the technical and operational aspects of energy efficiency, including regulative elements.
The Maritime Executive has publiced SSPA’s article with focus on energy efficiency at their website Ways to Boost Energy Efficiency

Ways to energy efficiency

A fair trial – how to obtain the correct EEDI
IMO recently passed a resolution on the Energy Efficiency Design Index (EEDI). This index is a measure of the amount of carbon dioxide a ship emits in relation to its cargo capacity and speed. A ship’s EEDI value must not exceed the allowable limit set by IMO. SSPA can help derive the hydrodynamic part of the EEDI value for new ships.
