Petronas Carigali Sdn Bhd subsidiary Vestigo Petroleum Sdn Bhd has completed the 68-km, 12-in. OD subsea pipelay for the Tembikai natural gas development in 70 m (230 ft) of water offshore Malaysia. The pipeline connects the non-associated gas development’s unmanned platform to the Berantai floating production, storage, and offloading vessel.
Cortez Subsea Ltd. partnered with Alam Maritim (M) Sdn Bhd in using NOV-Tuboscope’s Zap-Lok mechanical connector technology for the project. The project recorded a best average lay rate of 4.7 km/24 hr, with rigid pipelay completed in 20 days, according to Cortez. The rigid pipe was connected to flexible risers by using a stinger-deployed diverless connector, remotely operated vehicle, and a deployment frame.
Cortez’s work included engineering, procurement, construction, installation, and precommissioning of the pipeline system.
Vestigo launched the gas development project in 2018. Tembikai produced first oil in 2015 from a separate development.
