Free ClassNK Software for Shipyard EEDI Calculations

ClassNK releases Progressive Speed Trial Analysis Software 'PrimeShip-GREEN/PSTA' which analyzes the results from speed trials and calculates a corresponding ship’s speed in calm sea conditions for compliance with the amendment to MARPOL Annex VI.

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.

ClassNK says it 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.
