Introduction

This offshore standard provides principles, technical requirements and guidance related to stability, watertight integrity, freeboard and weathertight closing appliances for mobile offshore units and floating offshore installations.

The types of units and installations that are covered by this standard include:

— ship shaped units

— column stabilised units

— self elevating units

— deep draught units.

Guidance note:

For novel designs, not recognised by the typical features of a known type of design, the stability requirements have to be considered separately and based on an evaluation of risks reflecting the unit's design, the intended operational aspects and the environmental conditions.

The standard has been written for general worldwide application. Governmental regulations may include requirements in excess of the provisions by this standard depending on the size, type, location and intended service of the offshore unit or installation.
