The Assembly

 RECALLING Article 15(j) of the Convention on the International Maritime Organization concerning the functions of the Assembly in relation to regulations and guidelines concerning maritime safety,

 NOTING that mobile offshore drilling units continue to be moved and operated internationally,

 RECOGNIZING that the design criteria for such units are often quite different from those of conventional ships and that, by virtue of this, the application of international conventions, such as the International Convention for the Safety of Life at Sea, 1974, as amended, and the International Convention on Load Lines, 1966, as amended, is inappropriate in respect of mobile offshore drilling units,

 RECALLING that when the Code for the Construction and Equipment of Offshore Drilling Units (MODU Code) was adopted in 1979 by resolution A.414(XI) it was recognized that the design technology of mobile offshore drilling units was rapidly evolving and that new features of mobile offshore drilling units would be introduced to improve technical and safety standards,

 RECALLING ALSO that the Maritime Safety Committee was authorized to amend the Code as necessary after due consultations with the relevant organizations, as the Committee deemed necessary,

 NOTING that since the 1979 edition of the MODU Code was adopted there have been a number of tragic MODU casualties which have emphasized the need for a review of the international safety standards developed by the Organization,

 HAVING CONSIDERED the recommendation made by the Maritime Safety Committee at its fifty-seventh session,

  1. ADOPTS the Code for the Construction and Equipment of Mobile Offshore Drilling Units, 1989 (1989 MODU Code), the text of which is set out in the Annex to this resolution, which supersedes the existing MODU Code adopted by Assembly resolution A.414(XI) for mobile offshore drilling units whose keels are laid or which are at a similar stage of construction on or after 1 May 1991 ;

  2. INVITES all Governments concerned:

  • (a) to take appropriate steps to give effect to the Code;

  • (b) to consider the Code as an equivalent, for purposes of application to mobile offshore drilling units, to the technical requirements of the above-mentioned Conventions;

  • (c) to inform IMO of measures taken in this respect;

  3. AUTHORIZES the Maritime Safety Committee to amend the 1989 MODU Code, when appropriate. taking into consideration the developing design and safety features after due consultation with appropriate organizations.
