Minimum propulsion power evaluation software extended to calculate added resistance in irregular waves

Classification society ClassNK has released the latest version of its PrimeShip-GREEN/MinPower software.

The software was originally developed by ClassNK and released in April 2014 to help shipyards comply with amendments to MARPOL Annex VI, specifically EEDI requirements, by calculating minimum propulsion power requirements in compliance with the IMO 2013 INTERIM GUIDELINES FOR DETERMINING MINIMUM PROPULSION POWER TO MAINTAIN THE MANOEUVRABILITY OF SHIPS IN ADVERSE CONDITIONS. With this updated software, users will now be able to calculate the added resistance in irregular waves, allowing for minimum propulsion power requirements to be determined to an even greater accuracy.

To evaluate the minimum propulsion power requirement, added resistance in irregular waves must be calculated with ship's lines. ClassNK incorporated a new calculation module into the software to calculate the added resistance in irregular waves accurately developed by National Maritime Research Institute of Japan in addition to simplified formula for calculating added resistance in waves using only basic information.

The PrimeShip-GREEN/MinPower software is provided to shipyards free of charge. Application forms can be downloaded from below website: PrimeShip.
