MODE CODE 2009 INCLUDING 2020 AMENDMENTS

This is the most important document released by the IMO in connection with the Mobile Offshore Drilling Unit safety. This document of 2009 has been amended several times to include the IMO Resolutions adopted after 2009. The present publication contains all amendments up to and including those of 2022 and is the current version of the Code.

The arrangement of the content is pretty traditional for the IMO MODU Code – the first section provides general information on the purpose of this regulatory document, its application areas and definitions used throughout the text, survey and certification requirements etc. The second section of the Code deals with the construction of the Units, the hull strength and materials used for construction.

The third section is devoted to the stability and freeboard including the hull subdivision and watertight integrity requirements. After that there are requirements concerning the machinery installations including boilers, propulsion machinery for self-propelled drilling units, elevating systems installed on jack-up rigs, hull systems etc.

The electrical installations are dealt with in a separate section, followed with the one on the hazardous area classification and associated requirements. The rest of the volume addresses such the critical aspects as fire safety, lifesaving equipment and systems, radiocommunication equipment, cargo gear, operational aspects, chopper facilities and, finally, the air test appliances used in the confined spaces.
