Offshore Water Jetting

Calder offshore MultiJet pump units are designed and certified to undertake high and ultra high pressure waterjetting applications in Zone 1 and Zone 2 hazardous area locations. Designed to allow operation on drill rig, production platform or FPSO, these offshore high pressure pump packages can be safely used for cleaning and surface preparation in superstructure and fabric maintenance projects including heli-decks, accommodation areas, walkways, pipes and supports, plus waterjet abrasive cold cutting of tanks, pipes and decks and other composite materials. High pressure waterjetting is a dust-free technique which allows other adjacent activities such as painting and lagging to continue, minimises the waste stream created, reduces clean-up time, is not weather dependent, and when used in surface preparation operations is proficient at exposing the original profile without further erosion and guarantees the highest level of cleanliness of all surface preparation methods. Ancillary vacuum equipment can be used in conjunction with the offshore high pressure pumps to contain all washings and contaminants and, once filtered, washings can be reused and contaminants disposed of as appropriate.

As well as our MultiJet offshore high pressure pump units, we manufacture hazardous area vacuum units and hot water high pressure washdown packages, providing customers with cost-effective, compliant and environmentally sound solutions to Zone 1, Zone 2 and rig-safe cleaning tasks.

Container and Crash Frame Units

Offshore pump packages are supplied in accordance with DNV 2.7-1 for offshore containers. Both crash frames and containers can be supplied complete with fork lift entry point and a certified sling set. Design features include lockable double access doors complete with galvanised hinges, external stainless steel bulkhead panels for access to controls and services connections, inlet water supply, air supply, discharge hose connections, and optional 110v/24v lights and yellow alert. Container units have the option for accommodating a bench with vice for routine maintenance and servicing.






NORSOK Z015

The offshore MultiJet can be designed to comply with, and operate to, stringent NORSOK Z015 specifications; units are inspected by a third party for compliance before being released to the customer.

Certification

Equipment and component parts are supplied to client specifications or compliant with Atex legislation. A comprehensive documentation package is compiled in accordance with client and hazardous area requirements. All Atex Category 2 electric motor driven units (Zone 1 applications) are SIRA registered and are pre-inspected by Offshore Inspection Services at Calder's manufacturing facility in Worcester before release.
