General

This standard, DNV-OS-H203, Transit and Positioning of Offshore Units, provides specific requirements and recommendations for positioning any type of offshore unit such as:

— semi-submersible units

— self-elevating units

— drilling ships

— floating productions and/or storage units

— loading buoys

— offshore installation vessels

— well intervention units.

Guidance note:

In this standard the term positioning covers the activities required to position a unit/vessel at an offshore location and the planning, analyses and testing required for documenting a safe condition of the unit/vessel at that location. The positioning is considered completed when the unit/vessel is ready for operation or operating under normal conditions, see 201, and all required analyses and testing have been performed and accepted.

This standard also provides specific requirements and recommendations for transit of mobile offshore units.

This standard does not include specific requirements to the strength/capacity of the mooring systems. For such requirements references are made to applicable codes and standards in Sec.4 B.
