The Deepwater Diamond Wire Saws (DWDWS) are designed for deep water cutting of horizontal or vertical pipe. The DWDWS is run on hydraulic power and controlled remotely. This delivers a more efficient cutting action with enhanced operator safety and greatly extended wire life. Three models are available to cut from 4 inch - 52 inch O.D. (DN100-DN1300).
The Subsea DWDWS 1604 Deepwater Diamond Wire Saw (part number 10-10-516-ROV) is designed for subsea cutting of horizontal or vertical pipe, casings and structure at depths up to 3000 meters (9843sfw) within a range of 4 to 16 inch (102 to 406mm) outside diameter. Hydraulically powered, the DWDWS 1604 is controlled remotely from the surface using the Subsea TCP Topside Control Panel and your power unit, or with the HPU-84 Subsea Hydraulic Power Unit with integrated TCP.
DWDWS 1604 may also be controlled by ROV and powered via zero leak hot stabs. Every DWDWS is equipped with a ROV compliant control panel featuring easily readable gauges and large, tapered color-coded knobs operating a clutched mechanism to resist breakage. All DWDWS models come standard with Advanced Syntactic Flotation with Adjustable Buoyancy, Auto Wire Feed / Retract System, Auto Synchronized Clamping and a sealed, pressure adjusted 3 circuit hydraulic system.
DWDWS 1604 ships with (1) continuous loop diamond cutting wire that is quickly and easily changed in the field. Order replacement 1604 wires as Part Number P09-071-710. A highly recommended accessory is the dedicated DWDWS 3604 Shipping / Deployment Basket (Part Number H11-029-000).
