API RP 2MIM
Mooring Integrity Management
|Publication Date:||1 September 2019|
This recommended practice (RP) provides guidance for the integrity management (IM) of mooring systems connected to a permanent floating production system (FPS) used for the drilling, development, production, and/or storage of hydrocarbons in offshore areas. The scope of this RP extends from the anchor to the connection to the floating unit (e.g. chain stopper) and includes components critical to the mooring system (e.g. turret bearings, fairleads, chain stoppers, anchors, suction piles).
Specific guidance is provided for the inspection, monitoring, evaluation of damage, fitness-for-service assessment, risk reduction, mitigation planning, and the process of decommissioning. This RP incorporates and expands on the IM recommendations found in API 2I and API 2SK. In the event of any discrepancy between API 2MIM and API 2I/API 2SK, API 2I/API 2SK will govern.
This RP is not intended for:
- structural steelwork of turret systems and TLP tendons, which are addressed by API 2FSIM;
- thrusters, power generation, or control system;
- mobile offshore drilling unit (MODU) or other temporary moorings that are deployed and retrieved frequently;
- vessels holding station via a dynamic positioning (DP) system, without the use of mooring.
