Years of burying cables and pipes by hand led us to design machines to do it.
Cable burial sled. About 6 m long, with a hydraulic cable-guide arm (400 × 400 mm), high-pressure water-jet nozzles, a weight-adjusting skid and burial depth up to 3,500 mm.
Pipeline trencher. For a 700 mm pipeline, on an A-frame with a 10-tonne block, a 150 mm high-pressure sand pump, a 200 mm airlift, water-jet nozzles and rollers, with adjustable burial depth.
Alongside these we drew a jet-nozzle test rig, a plough-type concept and a cable stopper for the AAG sea-earth cable at Tong Fuk.
