Revolutionary SealWelding™ technology from Trelleborg Sealing Solutions allows seals to be welded in-situ on an FPSO platform, eliminating the need for the vessel to disconnect and return to shore
Innovative SealWelding™ technology reduces FPSO downtime
Utilizing Trelleborg’s well-established seal materials, our technology can massively reduce the downtime and associated costs that come from maintaining an FPSO swivel stack. Currently, swivel stack maintenance requires a vessel to travel back to shore so that components can be completely disassembled and seals replaced. Through optimized billet welding, Trelleborg’s SealWelding™ technology means a replacement seal can be welded in-situ in approved materials.
Offshore, on board the FPSO, the seal is unpacked and installed onto the swivel by personnel from Trelleborg’s service team; our skilled engineers install it in the Weld Head Enclosure (part of the welding system) which, certified to ATEX zone 1, is then pressurized so that the welding can take place. Fully enclosed, production on other swivel stacks can continue without risk.
following end of swivel stack seal service life
The original seal is removed on-site and a
new split Turcon® Variseal® is inserted
inside the swivel.
Turcon® Variseal® is welded
to correct diameter using the Trelleborg Sealing Solutions proprietary SealWelding™ process.
SealWelding™ process is complete
, equipment is removed and the Turcon® Variseal® is successfully welded together and ready for service.
