Electric-drivers Equipment
Electric-drivers Equipment is a cementing equipment for automatic slurry mixing and pumping operation on a new generation of dynamic positioning offshore deepwater drilling platform. The maximum mixing capacity can reach 16bpm, which is characterized by energy conservation and environmental protection, high mixing accuracy, near and remote full process automatic control.
Using frequency conversion motor instead of the traditional diesel engine, more energy saving and environmental protection;Split and modular design, more flexible installation , can provide multi-clock configuration extension;Using SUPER ACM-type system , which can precisely control the cement slurry density;Local and Remote automatic control, lmplement local and remote monitoring and operation;DNV certification, which is consistent with the international most advanced offshore platform certification;Pass the whole machine explosion-proof certification, can be installed in Zone II dangerous area.
China Oilfield Services Limited (COSL) is the leading integrated oilfield services providers in the Asian offshore market. COSL’s four main services divisions—Geophysical Services, Drilling Services, Well Services, and Marine and Transportation Services—cover the exploration, development, and production phases of the oil and gas industry.
