What to do after a hurricane?
After a hurricane moves on, work is performed to assess any damage that may have occurred, prepare for personnel to reoccupy the vessels, and resume drilling and production activities. Post-hurricane inspections and evaluations of mooring systems should focus on potential damage to on-vessel components (e.g., fairleads, etc.) to ensure that they are not damaged in a way that can cause excessive wear on the mooring components that run through them.
Chain and wire sections that reside near the surface, in the wave zone, and in the fairleads should be examined with special attention given to the grip areas, evidence of localised bending, and excessive wear. Wires should be evaluated for damage from dropped objects and parted strands near sockets and connections. Connecting links deserve close examination for loose pins and fittings. Line components in the touch-down / thrash zone, where lines are picked up and set down on the seabed as the vessel moves, also deserve special attention since that section is more likely to experience damage from grounding forces and abrasion.
Polyester rope components should also be examined for excessive damage to jacketing and sub-ropes and the potential for extreme tensions in permanent polyester moorings should be evaluated, as the subsequent rope elongations may affect the vessel’s overall station-keeping performance.
