This Guide specifies the ABS requirements for building and classing Mobile Offshore Units of self-elevating or column-stabilized type, not fitted with drilling equipment, production facilities, hydrocarbon storage, or any other system onboard handling hydrocarbons. Examples of Mobile Offshore Units covered by this Guide are:

• Accommodation Units

• Crane Units

• Construction and Maintenance Units

• Drilling Tenders

• Pipe and Cable Laying Units

• Wind Turbine Installation, Maintenance and Repair Units

and similar units used by the offshore industry.

The requirements contained in this Guide are for design, construction, and survey after construction of the Mobile Offshore Unit (including hull structure, equipment and marine machinery) and are based on the ABS Rules for Building and Classing Mobile Offshore Drilling Units (MODU Rules). Reference tables are provided to identify the requirements in the MODU Rules applicable to the Mobile Offshore Units.
