MEPC 73(39); Amendments to Regulation 13G of Annex I(Regulations for the Prevention of Pollution by Oil) make existing oil tankers between 20,000 and 30,000 tons deadweight carrying persistent product oil, including heavy diesel oil and fuel oil, subject to the same construction requirements as crude oil tankers. Regulation 13G requires, in principle, existing tankers to comply with requirements for new tankers in Regulation 13F, including double hull requirements for new tankers or alternative arrangements, not later than 25 years after date of delivery. The amendments extend the application from applying to crude oil tankers of 20,000 tons deadweight and above and product carriers of 30,000 tons deadweight and above, to also apply to tankers between 20,000 and 30,000 tons deadweight which carry heavy diesel oil or fuel oil. The aim of the amendments is to address concerns that oil pollution incidents involving persistent oils are as severe as those involving crude oil, so regulations applicable to crude oil tankers should also apply to tankers carrying persistent oils. Related amendments to the Supplement of the IOPP(International Oil Pollution Prevention) Certificate, covering in particular oil separating/filtering equipment and retention and disposal of oil residues were also adopted. A third MARPOL 73/78 amendment adopted relates to Annex II of MARPOL Regulations for the Control of Pollution by Noxious Liquid Substances in Bulk. The amendment adds a new regulation 16 requiring a Shipboard marine pollution emergency plan for noxious liquid substances. Amendments were also made to the International Code for the Construction and Equipment of Ships carrying Dangerous Chemicals in Bulk(IBC Code) and the Code for the Construction and Equipment of Ships carrying Dangerous Chemicals in Bulk(BCH Code). The amendments address the maintenance of venting systems,
