Chinese yard Dalian Shipbuilding Industry Corporation (DSIC Offshore) has signed two separate contracts with China Oilfield Services Ltd (COSL), the country's top offshore contractor, to build a deep-water semi-submersible drilling rig and a jack-up.
The semi-sub, to be built to the A5000 design of Norway's Agility Group, is a high specification unit capable of working in water depths of 5000 feet, and will have a drilling capacity of 30,000 feet.
In the signing ceremony held at COSL's headquarters in Yanjiao on Wednesday, DSIC Offshore committed to completing the fabrication in about 35 months.
The rig — to be named Hai Yang Shi You 982 — will be the sister unit to Hai Yang Shi You 981, an ultra-deepwater semi-submersible rated to 10,000 feet, and built by SWS two years ago. SWS was also in the running for COSL's latest rig building contract, as was CIMC Raffles.
