DEME’s peephole inspection design for CSD dredge pump is in the running to receive the IADC Safety Award 2023.
While performing dredging works on the parts of the Ok Tedi River in Papua New Guinea, DEME faced the following problem: the dredge pump and booster of its Cutter Suction Dredger (CSD) kept constantly getting clogged up with large amounts of timber, tree roots and other materials.
As a consequence, the pump inspection hatch had to be opened and closed up to 22 times per day, as there was no other way to check if the pump was blocked.
To avoid this inconvenience, DEME team have come up with a simple, but efficient solution: installation of a peephole that allows effortless inspection of the pump.
With this design , the crew are able to carry out an inspection of the pump with the advantage of literally being able to see “through” the pump.
