Book excerpt: Essential for all vessels who wish to enter an Emission Control Area, are at berth in a United Kingdom port, or a UK passenger ship operating in UK waters and controlled waters or any other passenger ship which calls at a port in the UK. The Merchant Shipping (prevention of Air Pollution from Ships) Regulation 2008, as amended, require that the master of a ship to which the regulations apply make a record to demonstrate compliance for any ship using separate fuel oils and make a record of any fuel changeover operation. The master of a ship to which the regulations apply is required to make a record: (a) in the case of a UK ship, in a log book in the format prescribed in Appendix 6 to Merchant Shipping Notice 1819 (M+F); (b) in the case of any other ship, in a ship's log book. This log book has been approved by the Maritime and Coastguard Agency for use on United Kingdom ships when recording the use of maritime fuel oil in accordance with the requirements of Annex VI of MARPOL and for ships at berth in United Kingdom ports in accordance with EU Directive 199/32/EC, as amended by Directive 2005/33/EC regarding the sulphur content of marine fuels.
