Minimum Propulsion Power required by the Amendments to ANNEX VI of MARPOL 73/78 (EEDI related Requirements)
Amendments to MARPOL ANNEX VI that make the "Energy Efficiency Design Index (EEDI)" and the "Ship Efficiency Management Plan (SEEMP)" mandatory were adopted at the 62nd session of the Marine Environment Protection Committee (MEPC 62) held in July 2011, and will come into force from 1 January 2013.
Relevant information on the amendments to MARPOL ANNEX VI has already been provided in ClassNK Technical Information Nos. TEC-0863, TEC-0872 and TEC-0929. This ClassNK Technical Information provides additional information regarding a specific requirement on minimum propulsion power specified in the amendment to MARPOL ANNEX VI.
1. Background
For ships to which the requirements regarding required EEDI specified in Reg.21 of MARPOL ANNEX VI apply, the installed propulsion power is not to be less than the propulsion power needed to maintain the manoeuvrability of the ship under adverse conditions as defined in the guidelines developed by the IMO, in accordance with Reg.21.5 of ANNEX VI.
After considerable deliberations at the 64th session of the Marine Environment Protection Committee (MEPC 64) held in October 2012 and the 91st session of the Maritime Safety Committee (MSC 91) subsequently held in November 2012, "Interim Guidelines for Determining Minimum Propulsion Power to Maintain the Manoeuvrability of Ships in Adverse Conditions" (hereinafter referred to as "interim minimum power guidelines") was developed and issued as MSC-MEPC.2/Circ.11.
2. Application
The interim minimum power guidelines are applicable only to bulk carriers, tankers and combination carriers to which compliance with an EEDI limit value (required EEDI) is required by Reg.21 of MARPOL ANNEX VI*.
* Applies to bulk carriers, tankers or combination carriers of 20,000DWT or above for which either the building contract is placed on or after 1 January 2013, or in the absence of a building contract, the keel of which is laid or which is at a similar stage of construction on or after 1 July 2013, or the delivery of which is on or after 1 July 2015.
