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 âIMO 2013 Interim Guidelines for Determining Minimum Propulsion Power to Maintain the Manoeuvrability of Ships In Adverse Conditionsâ. To evaluate minimum propulsion power requirement, added resistance in irregular waves should be calculated based on shipâs 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 specificationsâŚ
