The International Maritime Organisation's (IMO) Bulk Liquids & Gases Sub-committee (BLG), meeting this past February, failed to make decisions in a number of areas of concern to tanker operators, as its focus was very much on the agreement of revisions to air pollution codes. However, there was substantive agreement on proposed amendments to Annex I of the International Convention for the Prevention of Pollution from Ships (Marpol) covering the prevention of maritime pollution during ship-to-ship (STS) oil transfer operations.
