CIMC Raffles COSLPROSPECTOR set off a sea trial
On 8th Oct. 2014, COSLPROSPECTOR, the fourth semisubmersible drilling rig provided to COSL, set off a sea trial under the cooperation with Yantai Harbor Pilotage and Beihai Resure Bureau, the company said in its press release.
This sea trial is organized by CIMC Raffles, COSL, DVN, CCS, Rolls-Royce, Simens and Congsburg, aiming to commission and test for 609 sub-systems and 70 systems, including thrusters, PMS, DP, Close Ring, FMEA, communication, endurance capability, automatic cabin, lifesaving and mooring. During this sea trial, it is the first time to make engine management system close ring test applied to deep-water semisubmersible drilling rig in the whole world. Compared with usual power distribution design, it will reduce dynamos and 5% fuel. This environmentally-friendly system will be the mainstream power distribution design in high-performance semisubmersible drilling rig.
COSLPROSPECTOR is 104.5 meters long, 70.5 meters wide, 37.55 meters high, with operating depth 1,500 meters, drilling depth 7,600 meters and accommodation for 130, classified in DNV AND CCS. Due to over 10,000 control and alarm sets, the system is high-automatic, realizing remote monitoring in the cabin. The platform is equipped with the most advanced NOV AND DP3 systems, satisfied with PSA and NORSOK. Addition to the North Sea, it can work well for other sea areas.
In accordance with the "Quality Projects" standard, CIMC Raffles made breakthroughs in platform construction and design, hull structure, pipe electric installation, which was highly recognized by COSL. Compared with other three delivered semisubmersible rigs, the MC amount of this platform increases 45%, reaching 46,500 totally, and get through the strict test before seal trial.
CIMC Raffles commissioning team owned advanced system and process that can control MC and commissioning through PDCS system. Besides, it can realize dynamic quantization management to installation inspection procedure and inspection opinions, ensuring document tracking detailed and completed, and generate the required real-time monitoring project progress reports. The database system gets through twice by Statoil and has now become the core data management system of the marine project.
COSLPROSPECTOR started to build on 3rd Jul, 2012. The sea trial is the symbol that COSLPROSPECTOR will be delivered in a short time.
