DNV DNV-RP-G101 [ Active ]

This RP describes a method for establishing and maintaining a risk-based inspection plan for offshore pressure systems. It provides guidelines and recommendations on how to customise methods and working procedures that support the inspection planning process. .

This RP covers the planning of in-service inspection for offshore topsides static mechanical pressure systems when considering failures by loss of containment of the pressure envelope. Failure modes and functional failures, such as failure to operate on demand, leakage through gaskets, flanged connections, valve stem packing, together with valve passing and tube clogging are not addressed in this document.
