This FPSO had endured many years on station in the vicinity of the Shetland Islands when fatigue hot-spots were located in cargo oil tanks. LETS Global was contracted to strengthen the fatigue hot-spots against further structural fatigue.
After magnetic particle inspection the LETS Global Ultrasonic Peening Procedure was applied to all located fatigue hot-spots, extending the service life considerably. LETS personnel gained access to concerned areas with rope access.
In total LETS personnel made four separate trips to the client’s offshore installation in order to execute the project.
