DNV規格 DNV-ST-N001, 2023: Marine Operations and Marine Warranty
Description
This standard addresses the marine operations that can occur during the development or decommissioning of an offshore asset or when objects are moved by water from one place to another. It addresses marine warranty survey requirements relevant to load-out, construction afloat, voyages and installation/removal and the load cases that should be addressed in the design and planning of these marine operations.
The integrity of the final structure in the installed condition is the responsibility of the assured and would normally be verified and accepted by the certifying authority. The marine warranty survey company takes no responsibility for the installed condition unless the marine warranty survey scope specifically addresses this case e.g. for jack-up location approval.
With the exception of location approval of mobile offshore units (MOUs) which are covered in DNV-ST-N002, /39/, this standard covers most offshore assets and operations that are likely to require MWS approval.
