Crew Reviews, Ratings & Info for Cosl-Prospector

On Thursday, east China's Shandong Province saw the successful delivery of the new deep-water semi-submersible rig, 'COSLPROSPECTOR.' This state-of-the-art rig, crafted by Yantai CIMC Raffles Offshore Limited, departed from the builder's deep-water wharf in Yantai City and has been handed over to China Oilfield Services Limited. With a remarkable accommodation capacity for 130 personnel, the 'COSLPROSPECTOR' is engineered for operations in seawater depths of up to 1,500 meters, capable of drilling down to an impressive 7,600 meters. Furthermore, it is designed to withstand winds of up to 117 km per hour, showcasing its robust engineering. Notably, the Yantai shipyard has now manufactured a total of nine deep-water semi-submersible rigs since the year 2010, underscoring its expertise in advanced maritime technologies.

On Wednesday, Yantai CIMC Raffles Offshore Limited proudly announced the successful delivery of the COSLProspector, the fourth mid-water semisubmersible drilling rig crafted for China Oilfield Services Limited (COSL). The handover took place in Yantai, Shandong, China, showcasing cutting-edge design that complies with the most stringent international standards, making it fit for the challenging conditions of the Norwegian North Sea. This Dynamic Positioning Class 3 (DP3) vessel spans 343 feet (104.5 meters) in length and 231 feet (70.5 meters) in width, with a towering height of 123 feet (37.55 meters). It boasts an impressive operational depth capability of up to 4,921 feet (1,500 meters) and a maximum drilling depth of 24,934 feet (7,600 meters) while enduring temperatures as low as minus 20 degrees Celsius. With a maximum variable deck load of 5,000 tons and accommodation for 130 personnel, the COSLProspector is a multifunctional platform that exemplifies innovation. Classified by DNV and CCS, this state-of-the-art drilling rig adheres to the highest standards set forth by PSA and NORSOK, ensuring reliability and safety. Additionally, the COSLProspector comes equipped with a sophisticated system of 10,000 controllers and alerts, enabling advanced remote monitoring in this highly automated unit. The vessel's design is based on the GM-4000 series and is a collaborative effort between COSL, CIMC Raffles, and AG (Agility Group), reflecting a commitment to pushing the boundaries of maritime engineering.

On Wednesday, Yantai CIMC Raffles Offshore Limited announced that the COSLProspector, a cutting-edge mid-water semisubmersible drilling rig, has officially embarked on its sea trials off the coast of China. This marks an important milestone as it is the fourth semisubmersible rig delivered to China Oilfield Services Ltd. (COSL). Supervised by Yantai Harbor Pilotage and Beihai Rescue Bureau, the sea trial is organized by a consortium that includes CIMC Raffles, COSL, DNV, CCS, Rolls-Royce, Siemens, and Congsburg. The sea trials are designed to test and commission an impressive 609 sub-systems and 70 various systems, focusing on vital elements such as thrusters, power management systems (PMS), dynamic positioning (DP), close rings, failure mode and effects analysis (FMEA), communication systems, endurance capacity, automated cabins, lifesaving equipment, and mooring solutions. Notably, this trial will feature the first-time application of the engine management system's close ring test on a semisubmersible. The innovative power distribution design showcased in the COSLProspector is engineered to optimize efficiency by minimizing dynamo use and reducing fuel consumption by 5%. This ecologically friendly system is poised to become the standard for high-performance semisubmersible drilling rigs. The COSLProspector measures an impressive 343 feet (104.5 meters) in length, 231 feet (70.5 meters) in width, and stands 123 feet (37.55 meters) high. With certifications from DNV and CCS, this semisubmersible is capable of operating and drilling at depths reaching 4,921 feet (1,500 meters) and 24,934 feet (7,600 meters) respectively, providing accommodation for up to 130 personnel onboard.
