Dredging & Excavation
DWT BAG10 Grab
The DWT BAG10 Grab is a 10 m³ ultra deep water grab operated through a salt water based hydraulic system. The grab is part of the Water Tooling Pack, a package covering the complete system from ROV to tool. Because the hydraulics use salt water, no compensators (oil reservoirs) are needed, and the DWT BAG10 Grab can operate at depths up to 6000 m. The DWT BAG10 Grab has a bucket capacity of 10 m³ and 4 × HD water gasket cylinders. It weighs 10 ton and has an SWL of 50 ton. The grab is 5550 mm long fully open, 2400 mm wide and 4250 mm high fully closed. The salt water hydraulics have a max working pressure of 120–320 bar and a water flow of 30–120 l/min.

The Buckleys Marine Survey Kit is a corrosion survey kit for marine structures. The kit comprises a weighted silver/silver chloride half cell, a plastic cable spool and a multimeter. The half cell is connected to the cable spool by 75 m of CSP 55/015 cable, and two other leads connect the spool and the structure to the multimeter. The half cell is housed in a PVC body with holes that let water flow around the cell, and it is weighted to help keep it in position. In use, the multimeter is connected to the structure (+ terminal) and the cable spool (− terminal), the half cell is lowered into the sea at the desired position, and the multimeter set to the DC voltage range displays the corrosion voltage. The kit can be tailored to customer requirements. The half cell measures 140 mm long × 25 mm diameter and has an output of −5 mV @ 25 °C to a calomel reference cell, with an accuracy of ±10 mV in 3 % sea water.
