On Dec 18, 2020, CNOOC Limited the China's largest producer of offshore crude oil and natural gas company awarded the COSL Drilling Europe AS’s (CDE) Semisubmersible the COSL Prospector for drilling work offshore China. The contract is expected to start from mid January 2021 and run until mid December 2021. The duration of contract would be around 334 days. The day rate is undisclosed.
On May 25, 2020, COSL Drilling Europe AS (CDE) signs Master Framework Agreement with Equinor on the Norwegian Continental Shelf, that fully enables COSL to provide additional drilling units and services to Equinor. The agreement will strengthen the corporation between the companies and to facilitate long-term collaboration at all levels. The parties will commit to work on technology development as well as operational enhancements with initiatives to limit greenhouse gas emissions from drilling operations. The agreement also lays out framework for delivery of integrated services.
Equinor is still our most important customer. We have very effective rigs with a technology that can help Equinor reach its recently announced goal of an “emission-free” Norwegian continental shelf. One of our rigs that Equinor uses, has been rated their best rig multiple times the last five years, says Tollefsen and ads:
- With this agreement we can now fully compete for Equinor contract awards on the same terms as our competitors. I am very pleased with that. This is great news for us going forward, once the current situation normalises

On 30th April 2015, the COSLProspector semisub officially left the deep-water 
wharf of CIMC Raffles and joined the deepwater fleet of CNOOC. COSLProspector is the fourth deepwater semisubmersible drilling rig delivered by CIMC Raffles for China Oilfield Services Limited (“COSL”). It can operate in all sea areas except for the arctic. The operational water depth is up to 1,500 meters, whilst drilling depth is up to 7,600 meters, designed temperature -20?, accommodation for 130 personnel and the maximum variable deck load of 5,500 tons.
On 19 Nov 2014, COSLPROSPECTOR, the fourth deep-water semisubmersible drilling rig built by CIMC Raffles for COSL, has been delivered in Yantai, Shandong. The unit has the ability to work in the harsh Norwegian North Sea. The COSLPROSPECTOR is a DP3 vessel with length of 104.5 meters, width of
70.5 meters, height of 37.55 meters, and an operating depth of 1,500 meters, a drilling depth of 7,600 meters and a designed operating temperature of minus 20 degrees Celsius. A maximum variable deck load of 5,000 tonnes, the multi-function platform is also able to accommodate 130 personnel. It is classed by DNV and CCS, and satisfied with the strictest standards of PSA and NORSOK. Equipped with 10,000 controllers and alerts, the remote monitoring can be achieved in this high-automatic unit. On the base of GM-4000 series, COSLPROSPECTOR is jointly designed by AG (Agility Group), COSL and CIMC Raffles.
It adopts the most advanced power management and environmentally-friendly design concept, and facilities with DP3 close bus-tie, variable frequency drive, escape chute system and auto ice-cleaning technology. Compared with last delivered COSL series semisubmersible drilling rigs (COSLPIONEER, COSLPROMOTER and COSLINNOVATOR), COSLPROSPECTOR adds ICE-T, CLEAN and WINTERIZATION, to satisfy ice-class, environmentally-friendly and low-temperature requirements. COSL Prospector is made up by 112 blocks, over 700 mechanical equipment, more than 800,000 meters cable and 35,000 pipes. There are 46,500 test points of MCR, which is increased by 45% compared with three semi drilling rigs of the same series delivered already. 118 significant technical improvements have been made. In addition, weight deviation between inclined test and theoretical calculation is 80 tons and the noise level is controlled less than 45 dB in the living area.
