Trelleborg to slash downtime with new SealWelding technology

Manufactured from Trelleborg’s already well-established seal material, this new technology will 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.

“The offshore oil and gas sector has been going strong since the late 1940s, however, as the industry continues to move toward even more demanding offshore applications in order to drill deeper and reach further, the use of floating production, storage and offloading vessels have become particularly popular in recent years. While these offshore facilities have opened the potential of oil and gas exploration and production, maintaining them can often prove difficult and time consuming, especially as environments become more challenging,” commented Henk-Willem Sanders, Technical Manager Europe, Trelleborg Sealing Solutions.

“This is because with a number of component failures able to easily lead an FPSO to a shutdown that requires onshore maintenance, the cost and travelling time required to return an FPSO to shore can very quickly add up. In fact, when maintaining the swivel stack, a critical element onboard any facility, typically the FPSO would be down for between six and 12 weeks and the cost of that could rise to 100s of millions of dollars.
