General 

This standard is applicable to hull and topside of ship-shaped offshore units, such as drilling units, floating production and storage units, constructed in steel for both non-restricted and restricted operations. 

This standard covers the following structural items:

— material selection and fabrication principles

— design principles

— design loads

— ultimate strength requirements

— fatigue requirements 

The environmental loads used for the longitudinal strength calculations for the survival condition is based on the 10-2 annual probability of exceedance (100 year return period). 

Flag and shelf state requirements are not covered by this standard.
