This will be used to rehabilitate various 6-in., 8-in., and 10-in. subsea crude oil gathering and high-pressure gas and condensate lines, varying in length from 700-3,500 m (2,296-11,483 ft).
Petronas’ proprietary InField Liner system is a flexible Kevlar-reinforced liner installed in existing subsea pipelines. Once in place, the system acts as a corrosion barrier, providing protection against aggressive service conditions and extending the use of the pipeline beyond its original design life.
The system has been independently tested by a third party to meet oil and gas industry standards API 17J (2008), 15S 2006; DVGW G 469-2010; DIN 53536 (1992) and ASTM F1545-97, D4060, D1599-99. It can extend pipeline lives by up to 30 years, APS claims.
Petronas has also granted APS a 20-year exclusive license to apply the technology for other oil and gas operators worldwide.
