3400 Guidelines for the management of structural ALE issues for mono-hull FPSOs

Overview:

These guidelines support duty holders, operators and contractors with the structural integrity management (SIM) of ageing FPSOs in the oil and gas industry.

The focus of this document is on hull structures for mono-hull FPSOs, including cargo oil tanks, water ballast tanks, voids, internal caissons, topside module structural connections which integrate with the hull structure, etc.

This document excludes guidance for the following:

• semi-submersible structures;
• topside structures;
• marine systems;
• watertight integrity;
• optional aspects;
• turrets and station keeping systems, and
• subsea-to-surface interface equipment, i.e. risers, mid-water arches, umbilicals, etc.
