Here at Trelleborg, we’re committed to meeting the demands of both shallow and deep water tandem mooring operations. We strive to provide operators with best-in-class solutions that enable vessels to be moored safely and efficiently, even in the harshest offshore environments.

So, I’m delighted to reveal that we have been awarded the contract to supply complete tandem mooring systems to two floating production, storage and offloading (FPSO) vessels in Angola, West Africa.

The Angola-based FPSO tandem mooring projects demanded robust solutions that were capable of performing in particularly demanding offshore applications, while of course, adhering to project quality documentation processes and Class rules. In addition, the projects also required the long-term provision of technical and field support services.

Our 30 years’ of experience designing, manufacturing and commissioning high performance equipment for FPSO projects, coupled with our ability to provide dedicated support throughout the full project timeline, saw us chosen as the candidate to deliver the demanding requirements of the projects.

Our tandem mooring-winch and integrated Quick Release Hawser Hook (QRHH) system was installed onto the stern of the FPSO and used to moor a shuttle tanker in open sea conditions, with a separation of up to 150 meters. The mooring system includes integrated mooring tension monitoring, as well as a remote release system that can instigate an emergency release of the FPSO / shuttle tanker mooring from the FPSO stern deck or vessel’s control room.

Releasing the hooks from a remote location not only ensures complete oversight of the conditions of both the FPSO and the vessel, but also removes the need for jetty personnel to be close to the hook when a loaded mooring line is released which significantly reduces the risk of injury.
