Othercorrection factors, for example for voluntarystructural enhancement, are underdevelopment.Some proposed measures, such as kitesor solar panels, cannot provide power allthe time and will not enable the mainengine power and thus the EEDI to bereduced. At the moment, there are noguidelines for how such measures can beapplied to reduce the EEDI, but theseare expected to be developed at a laterstage, most likely through the Peff parameter.Propulsion efficiency devices, suchas Mewis ducts or propeller boss cap finscan either reduce the main engine power(Pme), or enable the ship to obtain a higherspeed (Vref).Further, the use of biofuels is not coveredby the current framework as their6 | Tanker UPDATE NO. 2 2011
CO2 emissions from shipsPhoto: Geostockcarbon content cannot easily be determined.There are no indications regardingif and when guidelines for biofuelswill be developed.Further work A number of guidelinesare going to be developed during the nextfew years, with the most important beingissued before the EEDI and SEEMP enterinto force in 2013:■■February 2012 – MEPC 63: Guidelinesfor minimum propulsion power■■■■■■October 2012 – MEPC 64: Guidelines onvoluntary structural enhancementJuly 2013 – MEPC 65: Guidelines forCO2 abatement technologiesMarch 2014 – MEPC 66: Guidelines forcalculation of EEDI for roro, passenger,diesel-electric and hybrid propulsionshipsThe requirements and dates are subjectto two reviews: the first is on the requirementsfor small ships and large bulkersand tankers and is due in July 2013. Thesecond review allows for a discussion ofboth the requirements and the time linefor when Phases 2 and 3 are to enter intoforce, and is due in January 2015. Tanker update NO. 2 2011 | 7
