GMC Limited has announced that following its two recent caisson awards from North Sea operators, the company has been awarded a third caisson fabrications contract. All three awards will utilize GMC’s unique multi-tooth mechanical connector, specifically designed for replacement caisson applications.

GMC continues to expand its Sea Water Lift (SWL) caisson replacement service in providing Operators with a fully managed caisson fabrication service, including client specific coating requirements, and often working to tight delivery schedules.

SWL caissons are integral to the health and safety of the personnel working on board the platform. Maintenance is a vital part of the offshore routine in order to maintain the integrity of the platforms and safety critical appurtenances that have now exceeded their original design life.

Using the GMC mechanical connectors mitigates the risks associated with a naked flame, when the caisson spools are welded. A typical weld could take up to four days to make the connection, whereas, the GMC connector takes approximately 30 minutes. This is a drastic reduction in off shore time required.

The SWL Caisson replacement project, as a whole, is an example of utilizing existing innovative technology to replace traditional installation methods, with the aim of reducing risks offshore. The connectors avoid the need for welding and its associated risks, as well as, reducing the total installation time, which also reduces the shutdown time and improves the economic sustainability of the platform.

Projects of this nature are becoming more frequent and highlight the need for regular inspection and maintenance across the industry, especially at a time when operators are looking to cut costs.

With the GMC Mechanical Connector, operators now have a safe and efficient fabrication and installation service that delivers considerable cost savings, whilst at the same time, extending the life of aging assets.
