The Amendment to MARPOL Annex VI came into force from January 2013, enforcing mandatory EEDI calculation and EEDI regulation values for vessels contracted from 1 January 2013 onwards. When calculating EEDI, external factors such as the wind, waves, tides, shallow waters, and displacement during speed trials can be corrected for to allow for higher accuracy when determining a ship’s speed in calm sea conditions.
ClassNK developed this software to provide a straightforward method for compensating for external factors in progressive speed trial analysis based on ISO Standard 15016:2002, recognized in the IMO EEDI Guidelines “2012 GUIDELINES ON SURVEY AND CERTIFICATION OF THE ENERGY EFFICIENCY DESIGN INDEX (EEDI)”.
ClassNK is committed to supporting the maritime industry in complying with new international conventions, and is constantly developing various support tools among others as part of this commitment.
PrimeShip-GREEN/PSTA is provided to shipyards free of charge. To apply, please complete the application form available from the link below and return to the ClassNK EEDI Division.

Leading classification society ClassNK (Chairman and President: Noboru Ueda) has announced the development of the software, PrimeShip-GREEN/PSTA (Progressive Speed Trial Analysis), to help shipyards comply with the Amendment to MARPOL Annex VI making calculation of a vessel’s EEDI (Energy Efficiency Design Index) mandatory. The software analyzes the results from speed trials and calculates a ship’s speed in calm sea conditions.
