ClassNK updates EEDI verification tool

23 Sep 2014

ClassNK has released the latest version of its PrimeShip-Green/MinPower software, developed earlier this year to help shipyard comply with amendments to MARPOL Annex VI.

The software was developed to help ensure shipyard comply with IMO guidelines, specifically EEDI requirements, by calculating minimum propulsion power requirements. With this updated software, ClassNK says users can now 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. For this reason, ClassNK has incorporated a new calculation module into the software, 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.
