Crude Oil Washing Operations and Equipment Manual

 Every tanker which operates with crude oil washing, in accordance with Regulation 13, must be provided with an Operations and Equipment Manual, approved by the Administration. The Manual must detail the system and equipment and specify operational procedures (Regulation 13B of Annex I of MARPOL 73/78).

 As the purpose of the Operations and Equipment Manual is not only to provide guidance to the crew of the ship for the proper operation of the system but also to provide information on the system and its operational procedures for inspectors going on board for inspection in ports, the Marine Environment Protection Committee decided to develop a standard format for the Manual. It is hoped that the standard format will help shipowners in preparing the Manuals for their ships and Administrations in approving them.

 The standard format contains:

  • (1) Standardized wording for the introduction of the Manual

  • (2) Index of the Manual

  • (3) 18 sections, detailing the information or operational instructions to be provided under each section as required by the revised Specifications for the Design, Operation and Control of Crude Oil Washing Systems (Assembly resolution A.446(XI) as amended by resolution A.497(XII) and resolution A.897(21)).

 Administrations may require information and operational instructions to be included in the Manual in addition to those specified in the standard format. Such information should be included in part 2 of the Manual. If no such information or operational instructions are required, the Manual will consist of one part only.

 This publication also contains two examples of the Manual developed by tanker owners in accordance with the standard format for two actual tankers, one of which is a conventional pipeline tanker of about 315,000 tons deadweight and the other a full free flow tanker of about 270,000 tons deadweight. As will be seen from these two examples, the information and operational instructions under the corresponding sections vary considerably in their wording and presentation.

 It should be noted in this connexion that:

  • (1) What is standardized is the type of information to be included in the Manual under each section and not its presentation.

  • (2) The two examples show how the Manuals may be presented. Although some sections may be generally applicable to all ships, these are merely examples and should be treated as such.

 The attention of Governments is drawn to the recommendation made by the MEPC, inviting them to use the standard format when approving the Manual and to ensure that, if the language of the Manual is neither English nor French, the Manual includes a translation into one of those languages.
