As adopted by the resolution MEPC.186(59), a new chapter 8 to the MARPOL Annex I is introduced and Regulations 40,41 and 42 included, state that all oil tankers of 150 Gross Tonnage and above engaged in the transfer of oil cargo between oil tankers at sea (STS Operation) conducted on or after 1 April 2012, are required to have onboard and should implement an STS Operation plan approved by the Administration.
Since these new Regulations under MARPOL ANNEX I will enter into force on 1 January 2011, Streamlined Naval Architects have already developed an easy-to-use STS Operations plan, in accordance to the information contained in the IMO “Manual on Oil Pollution, Section 1 Prevention” as amended, and the ICS and OCIMF “Ship to Ship Transfer Guide, Petroleum, fourth edition, 2005”.
In detail, as quoted from Regulation 41 :
