15 May 2015 Dry Bulk | Shipping & Transport ClassNK has released PrimeShip-GREEN/ProSTA, making it the world’s first classification society to develop software which analyzes and calculates a ship’s speed trial results for EEDI calculation in compliance with the latest IMO Guidelines on 1 May 2015. ClassNK has also developed support tools such as PrimeShip-GREEN/ProSTA for shipyards, shipowners, and the greater maritime industry to enable smooth adoption of the amended standard. The software enables ship designers to calculate the ship’s speed in compliance with ISO15016:2015 and reduces the workload required for EEDI calculation.
