Product Sheet CPS-763 Ultradeepwater Cementing Pump Package
High-pressure pumping with up to 860 kW for ultradeepwater and semisubmersible applications.
Performance expectations are extreme for cementing units onboard ultradeepwater drillships and semisubmersibles. Maximum cement mixing rates and downhole pump rates are critical to improve overall rig efficiency and save valuable time.
The CPS-763 cement pumping skid was designed and built to exceed these extreme requirements. The 1,193-kW [1,600-hhp] unit has the capability to pump 3.8 m3/min [24.4 bbl/min] and can be used at working pressures up to 103 MPa [15,000 psi]. It is optionally equipped with a high-efficiency mixing package of dual Mark III SLURRY CHIEF cement mixers with averaging tanks capable of 3.5-m3/min [22-bbl/min] rates for lead slurries and 2-m3/min [15-bbl/min] rates for standard tail systems.
Two electrically driven 16-m3 [100-bbl] batch mixers can be integrated for spacer or pill mixing isolated from contamination points. A high-rate, process-controlled, direct-injection liquid additive system provides the ability to meter up to six chemicals into the mix-water stream.
Data acquisition and control is handled by two complete systems for redundancy and reliability of automated mixing, solids fraction monitoring, foam process control, and liquid additive system.
