Vestigo Petroleum | Pipeline Installation 2020

The Tembikai Non-Associated Gas (TNAG) pipeline system consisted of a 12-inch, 58km gas pipeline tied in from an unmanned wellhead platform (WHP) to the Berantai floating production, storage and offloading (FPSO) facility, offshore Peninsular Malaysia.  The project also included a 58km subsea fibre optic cable which was installed along the pipeline route to provide data communications.  Cortez Subsea leads the charge in new and proven technology for quicker, safer and cleaner subsea pipelay and championed the Zap-Lok™ mechanical interference connector as a weld-free alternative to traditional methods.  This was the first time this technology, which allows for much faster and more efficient pipelay, has been used offshore Malaysia. In another industry first, the rigid pipe was connected to the flexible risers using the Cortez Subsea and AFGlobal developed Stinger Deployed Diverless Connector (SDDC).  Work class ROVs with Photo Realistic 3D Cloud (PRC) technology were also used for the inspection and survey of the pipeline system once installed and allowed us to ensure operational excellence regarding positional measurement throughout. The pipeline installation, end to end, was completed in 20 days with best average lay rate of 4.7 km in 24 hours, three times faster than traditional pipelay.
