CPS 730 Cement Pumping Skid | SLB


Cement pumping skid

A completed CPS 730 cement pumping skid inside a manufacturing facility.

The CPS-730 cement pumping skid is a twin-pump offshore cementing unit that provides cementing and pressure pumping capabilities in deepwater environments. Two General Electric (GE) motors provide a combined horsepower of 1,200 bhp. The motors drive two triplex pumps that deliver a maximum flow rate of 18.5 bbl/min and maximum pressure of 15,000 psi.

The mixing system enables cement slurries to be mixed at conventional rates. Cement mixing processes are fully automated, with autodensity control for consistent cement slurry properties and performance. Cement mixing and pressure pumping processes are fully remote controlled, with local operation available as backup.

The CPS-730 skid meets DNV-OS-A101 standards for operation in Zone 2 hazardous areas.
