ClassNK Releases EEDI Verification Software – Free
ClassNK has released its new PrimeShip-GREEN/MinPower software, developed to help shipyards comply with the EEDI requirements of the Amendment to MARPOL Annex VI by calculating minimum propulsion power requirements in compliance with ‘IMO 2013 Interim Guidelines for Determining Minimum Propulsion Power to Maintain the Manoeuvrability of Ships In Adverse Conditions’. To evaluate minimum propulsion power requirement, added resistance in irregular waves should be calculated based on ship’s Lines, and this calculation can be difficult especially at the initial design stage. Consequently ClassNK has developed this simplified formula to calculate added resistance in waves using only basic information such as main ship specifications…

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.
