Crude Oil Washing Systems - Foreword

Foreword

. This publication contains:

. Revised Specifications for the Design, Operation and Control of Crude Oil Washing Systems (resolution A.446(XI)), as amended in 1981 (resolution A.497(XII) and resolution A.897(21)).

. Standard format for the Crude Oil Washing Operations and Equipment Manuals

. Examples of Crude Oil Washing Operations and Equipment Manuals

. Guidelines for In-Port Inspection of Crude Oil Washing Procedures

Revised Specifications

. The International Conference on Tanker Safety and Pollution Prevention (TSPP Conference) convened by the International Maritime Organization (IMO) in February 1978 adopted, inter alia, the Protocol of 1978 relating to the International Convention for the Prevention of Pollution from Ships, 1973, which modified the 1973 Convention. see footnote MARPOL 73/78 requires certain ships to operate with a cargo tank cleaning system using crude oil washing (Regulation 13 of Annex 1 of MARPOL 73/78). The crude oil washing installation, associated equipment and arrangements, must meet the requirements established by the Administration based on the Specifications for the Design, Operation abnd Control of Crude Oil Washing Systems adopted by the Conference in resolution 15 and as may be revised by the Organization (Regulation 13B of Annex 1 of MARPOL 73/78).

. The Conference requested the Organization to review and revise the Specifications, as necessary, in order that the revised Specifications would reflect the latest technology and practices which might be developed by the time of entry into force of MARPOL 73/78.

. The task of reviewing and revising the Specifications was carried out by the Marine Environment Protection Committee (MEPC) of the Organization at its tenth and eleventh sessions as a matter of urgency. In the course of its work, the MEPC found that there was a need, not only to revise certain provisions of the Specifications, but also to agree on interpretation of some of the provisions.

. The Assembly of the International Maritime Organization, at its eleventh session, received and examined the recommendations made by the MEPC on this matter and adopted, by its resolution A.446(XI) of 15 November 1979, the revised Specifications for the Design, Operation and Control of Crude Oil Washing Systems together with agreed interpretations of certain of the provisions of the revised Specifications. As stated in the resolution, the revised Specifications supersede the Specifications contained in the Annex to resolution 15 of the TSPP Conference.

. Since the eleventh session of the Assembly, the MEPC kept the revised Specifications under review and recommended certain amendments and additions both to the revised Specifications and to the agreed interpretations; these were adopted by the Assembly at its twelfth session by resolution A.497(XII) of 19 November 1981.

. The attention of Governments is drawn to the fact that the Assembly urged them to establish, in time for the entry into force of the MARPOL 73/78 requirements for the crude oil washing installation and associated equipment and arrangements based on the revised Specifications, and urged further that such requirements should not impose requirements over and above those laid down in the revised Specifications.

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
