The ultimate cleaning system for the subsea infrastructure.
The Deep Water Cleaning System (DWCS) is the world's first subsea deployed patented manifold, tree and pipeline remediation cleaning system.
Delivering high-quality results in a fraction of the time required by conventional methods, DWCS enables Pipetech to complete cleaning operations remotely in subsea manifolds, trees and pipelines.
Utilising high-pressure water, we remove any naturally forming foreign body material in the subsea environment to return the operating system to full flow efficiency.
Pipetech has developed the ultimate remediation cleaning system for subsea pipelines, manifold and trees. The DWCS is a compact technology that sets an entirely new global standard for subsea cleaning operations.
The DWCS comprises a range of topside and subsea equipment to remove subsea scale, wax and other foulants. This high-pressure water supply from topside is routed through a large bore high-pressure downline to the DWCS and out through a specialised nozzle at the end of a feeder hose. A subsea guide frame/ or bespoke base is used as secure foundation for the DWCS to be coupled into the entry of the piping infrastructure.
■ The DWCS frame is designed according to DNV 2.7-3, TR1231 and DNV-RP-H103
■ The frame accommodates a single point lift with a 12 metric tons shackle
■ The design allows for a deployment through moon pool and/or by use of a crane from the side of the vessel
■ Sea depth: 500m with topside High Pressure water supply
■ Cleaning length: 30m
■ Cleaning speed: 1 foot per 2 minutes
■ High pressure water velocity 430 m/s
■ Can be operated in up to 4m wave heights
■ Manifolds
■ Trees
■ Pipelines
■ Can remove the widest range of scales from all subsea pipework
■ Removal of stuck pigging tools
