IMO GUIDELINES FOR THE OPERATION, INSPECTION AND MAINTENANCE OF SHIP SEWAGE SYSTEMS 1 The Maritime Safety Committee, at its sixty-first session (7-11 December 1992), instructed the Sub-Committee on Ship Design and Equipment to include an item on standards for the design and construction of sewage systems on ships in the Sub-Committees work programme. 2 This follows an incident on a passenger vehicle ferry which led to the tragic loss of life of two children. The investigation into this incident revealed several unsatisfactory aspects and highlighted the potential dangers associated with the operation of sewage systems on board ships if they are not installed, operated and maintained properly. 3 The installation, operation and maintenance of sewage systems on ships is not currently provided for in any of the international conventions. Against this background and in consideration of the action taken by the Irish and the United Kingdom Governments, the Sub-Committee on Ship Design and Equipment, at its thirty-seventh session, developed guidelines to promote uniform standards in relation to the examination of the installation, routine inspection and regular maintenance of these systems, to ensure safe operation at all times. The Maritime Safety Committee, at its sixty-third session (16 to 25 May 1994), approved the guidelines, set out at annex to the present circular. 4 The attention of Administrations and the industry is drawn to the recommendations contained in the guidelines and Member Governments are invited to apply them on all ships flying the flag of their State. ANNEX GUIDELINES FOR THE OPERATION, INSPECTION AND MAINTENANCE OF SHIP SEWAGE SYSTEMS Introduction 1 These guidelines apply to all ships.
