Omfang

The document provides guidance on managing the integrity of FPS and loading/unloading buoy weathervaning systems. This includes load and transfer subsystems and their interfaces with hull structures, platform tower structures, risers, umbilicals, and moorings. The following list summarizes the weathervaning subsystems that are covered: a) load transfer subsystems: 1) bearing assembly;  2) structures:  i) turret;  ii) turntable;  iii) buoys;  iv) hull support structures;  v) tower/yoke structures;  vi) access structures; 3) disconnectable locking system;  4) mooring appliances (interfaces); b) fluid transfer subsystem:  1) swivel stack assembly:  i) fluid swivels;  ii) electric swivels (low, medium, and high voltage);  iii) communication swivels (optical, signal, etc.);  iv) utility swivels (hydraulic, air, chemical, etc.);  2) riser appliances (interfaces and piping);  3) umbilical appliances (interfaces, piping, and conduit); c) other subsystems: 1) pull-in/installation/tensioning equipment. The regions of the hull or tower structure away from the immediate support of the weathervaning system and the regions of the risers, umbilical, and mooring lines below and away from the interface or connections to the weathervaning system are not included within this guidance. Guidance managing the integrity of these structures can be found in the following recommended practices: — hulls: API 2FSIM, Floating Systems Integrity Management;  — tower structures (fixed platforms): API 2SIM, Structural Integrity Management of Fixed Offshore Structures;  — permanent mooring systems: API 2MIM, Mooring Integrity Management;  — riser systems: API 2RIM, Integrity Management of Risers from Floating Production Systems.  The guidance provided in this informative is applicable to offshore areas worldwide. Purpose This document is intended to be used by owners and engineers concerned with the following: a) Decisions in a design that can influence the ability to maintain the long-term integrity of weathervaning systems. This relates to design features that can help facilitate integrity activities during operation. b) Developing and managing an IM program of weathervaning systems: 1) required OEM documentation; 2) baseline activities;  3) in-service integrity activities;  i) inspection; ii) maintenance;  iii) monitoring;  iv) spares;  4) personnel competencies.
