Abrasive water suspension jet -- A multifunctional working tool for underwater applications
- Univ. of Hannover (Germany). Inst. of Material Science
It is the aim of the paper to show the possibilities of Abrasive Water Suspension Jets (AWSJ) for underwater machining tasks in the offshore industry and other deep sea operations. The AWSJ is a remote-controllable and multifunctional tool for different underwater purposes like maintenance and repair as well as salvage, removal and decommissioning. Therefore it is possible to clean structures from rust and marine growth, to remove concrete and other functional coatings, to cut through different materials as well as composite materials and also to carry out the preparation for repair welding. First the paper will give some basic information about Abrasive Water Jets under water and about the equipment to produce AWSJ. Afterwards the possibilities of jet generation for cutting (round jet), cleaning and material removal (flat jet) and multifunctional operation will be demonstrated. Test results which were carried out under water will be presented. The influence of relevant parameters on processing efficiency is given and discussed.
