ClassNK launches EEDI ship speed calculation software

ClassNK has released its new PrimeShip-GREEN/ProSTA software system, used to analyse and calculate a ship’s speed trial results for Energy Efficiency Design Index (EEDI) calculation in compliance with the latest IMO Guidelines from 1 May 2015.

{mprestriction ids="1,2"}PrimeShip-GREEN/ProSTA aims to assist shipyards, shipowners, and the greater maritime industry in adoption of the new harmonised ISO 15016:2015 international standard for analysing and calculating a ship’s speed in calm sea conditions, set to be adopted at this month’s MEPC68.

MARPOL AnnexVI states one parameter to calculate EEDI as the ship’s speed in calm sea conditions based on the speed trial results. ISO 15016:2015, published on 1 April 2015, is an attempt to harmonise the two methods for calculating this figure that are found in IMO’s Guidelines on survey and certification of the EEDI (ISO 15016:2002 and the International Towing Tank Conference (ITTC) Recommended Procedures).

ClassNK’s new software enables ship designers to calculate a ship’s speed in compliance with the new ISO15016:2015 standard, and as a result can help to reduce the workload required for EEDI calculation, the class society says.

As a non-profit organisation, ClassNK says it will be offering this software completely free of charge to all applicants. Further details are available on the organisation’s website.{/mprestriction}
