The Maritime Safety Committee,

 The annex of this document has been consolidated into 2009 MODU Code

RECALLING Article 28(b) of the Convention on the International Maritime Organization concerning the functions of the Committee,

RECALLING ALSO that the Assembly, when adopting resolution A.1023(26) on the Code for the Construction and Equipment of Mobile Offshore Drilling Units, 2009 (2009 MODU Code), authorized the Committee to amend the 2009 MODU Code, as appropriate, taking into consideration developments in design and technology, in consultation with appropriate organizations,

RECOGNIZING that these requirements and provisions are very similar to the SOLAS requirements and that some of them, being applied to mobile offshore units, may lead to potentially hazardous situations, due to the fact that they have been developed on the basis of typical operations for conventional ships,

RECOGNIZING FURTHER the tragic loss of life and lessons learned from the explosion, fire, and sinking of the mobile offshore drilling unit Deepwater Horizon in the Gulf of Mexico, which occurred from 20 to 22 April 2010,

HAVING CONSIDERED, at its ninety-eighth session, the recommendation made by the Sub-Committee on Ship Systems and Equipment, at its fourth session,

1 ADOPTS, the amendments to the Code for the Construction and Equipment of Mobile Offshore Drilling Units, 2009 (2009 MODU Code), as set out in the annex to the present resolution, for mobile offshore drilling units, the keels of which are laid or which are at a similar stage of construction on or after 1 January 2020;

2 INVITES Member States concerned to take appropriate action to give effect to these amendments.
