Optimal ship operation: monitoring technology of ship overall heat balance

Abstract

International Maritime Organization (IMO) Marine Environment Protection Committee (MEPC) Circular 684 (Circ. 684) is a detailed explanation of the Energy Efficiency Operational Indicator (EEOI). So MEPC Circ. 684 is cited as it is in this section, including the annex, because IMO official documents must be transmitted unchanged. MEPC Circ. 684 is an invaluable reference for developing a real-time EEOI on board. The MEPC of the IMO, at its 59th session (13-17 July 2009), agreed to circulate the guidelines for voluntary use of the ship EEOI as set out in the annex. As a result member governments are invited to bring the Guidelines (MEPC.1/Circ. 684) to the attention of all parties concerned and to recommend that they use the Guidelines on a voluntary basis. IMO Assembly resolution A.963 (23) is related to the reduction of greenhouse gas (GHG) emissions from ships and it urges the MEPC to identify and develop such a mechanism or mechanisms as are needed to achieve first, the limitation or reduction of GHG emissions from international shipping, giving priority, in doing so, to the establishment of a GHG baseline; and secondly, the development of a methodology to describe the GHG efficiency of a ship in terms of a GHG emission indicator for that ship.
