Yantai CIMC Raffles Offshore Limited reported Wednesday that the company has delivered the JU2000E Coastal Driller 4001 (400' ILC) Aug. 13 to Malaysia's Coastal Contracts Bhd as the ninth jackup in Yantai, Shandong, China.

Coastal Driller 4001 is 230 feet (70.36 meters) long, 249 feet (76 meters) wide and 31 feet (9.45 meters) high, with leg length of 548 feet (167 meters), spud can diameter of 59 feet (18 meters), designed draft of 22 feet (6.7 meters), accommodation for 140 persons, maximum operation depth of 400 feet (122 meters), maximum drilling depth of 35,000 feet (10,668 meters), and minimum operation temperature of minus 20 degree. The rig was classified to ABS, with basic design by American company F&G, drilling package by Norway AKER MH, detail design and construction design by Shanghai offshore institute and Yantai offshore institute which belong to CIMC Group, and completed construction and delivery by CIMC Raffles.

Based on the design and construction experience of delivered jackups, CIMC Raffles optimized and innovated critical technology, craft procedure, and the construction, mating and installment of key structure and equipment. It employed a derrick barge to complete mating legs for the first time in China in the floating condition of main hull; it managed weighing cantilever in rig creatively and completing pre-blasting trail and jacking trail test in ultimate state; it achieved designing, constructing, installing and commissioning multi-blocks in parallel by employing the principle of “modular design and construction”, which improved the quality and reliability and reduced the construction period.

On the drilling package, it is the first time for a Chinese offshore firm to choose Norway's Aker. CIMC Raffles created brand new project management cooperation model, that is, shipyard and Aker carried out profound cooperation during drilling package’s preliminary design period and construction plan management.

On the production of critical components “jackup legs”, CIMC Raffles researched and developed core technology and craft procedure independently and overcame difficult issues such as deformation control of ultra-high strength and thickness plate, temperature control, quenching and tempering of material deformation, deformation control of rack cutting, welding craft etc., by which it fulfilled the manufacturing of rack bar and chord with approval of classification society.

Huang Zhenxing, the CEO of Coastal Contracts Bhd, said that Coastal Driller 4001 is Coastal’s first choice of serial drilling rigs. Its successful delivery proved the construction capability of CIMC Raffles and strengthened Coastal’s confidence of devoting to offshore field.

Coastal Contracts Bhd is a Malaysia-based marine incorporation that provides marine products and services to the shipping, oil and gas and commodities industries, and its main services include build, charter, repair, maintain and trade marine and offshore vessels. Coastal Contracts Bhd placed two orders in CIMC Raffles, one JU2000E jackup and one gas plant, and except for delivered Coastal Driller 4001, other two rigs are scheduled to be delivered in 2015.
