As cuttings reinjection has, over the last few years, become recognized as an environmentally responsible and cost-effective disposal method for offshore drill cuttings, we have been at the forefront of cuttings reinjection pump package development.

Our high pressure waste injection (CRI, cuttings re-injection) pumps are in use in hazardous areas around the world, both onshore and offshore, for continuous injection over a wide range of flows and pressures. They are used for the injection of seawater and slurries, drill cuttings, drilling muds and sand into subsea strata. Additionally, our waste injection pumps are suitable for a range of high pressure well service pumping applications.

Your CRI unit can be configured to include an electric motor with Variable Speed Drive (VSD) control, capable of providing a variable flowrate from 10% to 100% at the required duty pressure. Alternatively, diesel-driven systems are available with six-speed transmission. Additional configurations such as diesel/electro hydraulic drives are also available. We offer a range of noise hoods and enclosures which provide noise attenuation and weather protection.

Whatever your cuttings re-injection or waste injection requirements, our wealth of experience and ongoing design and development processes will ensure you receive a well service pump package designed for the job with the inherent reliability that has become synonymous with Calder.
