China’s first three.5” coiled tubing skid, collectively developed and manufactured by Jereh Group and CNOOC, was efficiently utilized within the South China Sea. It marks that the pre-commissioning of subsea pipeline in China has entered a brand new period.
Offshore oil & fuel improvement, particularly these for deep-sea oilfields, intensifies and requires extra subsea pipeline constructed. The pipeline pre-commissioning is essential to assist cut back future corrosion, maximize throughput, and prolong service life.
In China, the subsea pipeline is washed with glycol which are conveyed by high-pressure hoses. However, it usually comes with points like low stress resistance and sluggish recovering. Facing these challenges, Jereh R&D group and CNOOC engineers took thorough evaluation and developed the brand new three.5” coiled tubing skid for subsea pipeline pre-commissioning.
The gear has handed CCS certification, totally satisfying the necessities of marine working surroundings. Also, the skid is supplied with latest-developed gadgets resembling quick-change sprocket, yard spooler, lead screw and and so forth. In this fashion, the hurt on grippers and coiled tubing could be minimized.
In the in the meantime, Jereh has innovated the hydraulic drive in addition to electrical management system and has reserved the features of blowout preventers and stripe packers. Therefore, the skid options giant diameter, small resistance, low value, quick pipeline restoration and powerful anti-pressure functionality.
It is thought that CNOOC has made the South China Sea Subsea Development Strategy to construct extra deep-water oilfields on this space. Its first self-operated deep-sea fuel subject is estimated to achieve the capability of 35.three Bcf, requiring extra funding to unleash the potential and improve power provide in China.
