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.

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.
