MEPC187(59) came into force on 1 Jan, 2011. There are changes to the C 11 entries and a requirement for a C11.4 which is not included in the U.S. Coast Guard oil record book. Examples of the required entries are found in MEPC.1/circ.736/rev.2.
Missing this entry could cause problems with PSC.
The U.S. Coast Guard has issued a letter to vessel masters and Chief Engineers regarding the continued use of the 2007 ORB (Oil Record Book).
A post at Bryant’s Maritime Blog is here.
