ClassNK issues revised guidance on minimum propulsion requirements

PrimeShip-GREEN/MinPower ver.2.0 is released today, updating advice first issued in 2014.

For each ship to which ‘Required EEDI’ of MARPOL Annex VI applies, its installed propulsion power should not be less than the propulsion power needed to maintain the manoeuvrability of the ship in adverse conditions.

This evaluation has been required in line with ‘2013 Interim Guidelines for Determining Minimum Propulsion Power to Maintain the Manoeuvrability of Ships in Adverse Conditions’.

At MEPC 76 held in June 2021, the amendments to revise the definition of adverse conditions and incorporate R&D outcomes of SHOPERA and JASNAOE were adopted, and ‘Guidelines for Determining Minimum Propulsion Power to Maintain the Manoeuvrability of Ships in Adverse Conditions’ has been newly issued.
