Abstract (en)

[origin: CA1207603A] The underwater operating unit shown in Fig. 1 comprises a hollow body which is specially reinforced, against bending moments and compressive forces acting upon it, by means of flow-ducts (for drive-elements) passing longitudinally therethrough and by permanently incorporated, multi-purpose pressure chambers. Unit is held by, and supplied through, a holding- and supply-cable. A main grab, adjustable to widely varying gripping diameters and located at front-end, is adapted to cling to pipes, wrecks, and the like so firmly that the unit itself, and the booms extending therefrom (tool-arm, auxiliary grab, platform), may be subjected to heavy loading as a fixed work-base both for hand-tools operated by divers and for entirely remotecontrolled, un-manned manipulators, in spite of the small dimensions. Control-elements and drive-elements allow unit to be used both as a vehicle, as a mobile unit, as a hoist, as a machine tool, and as a power-base for auxiliary equipment used in underwater operations, also in confined pipestructures and cavities, in a particularly efficient and safe manner, and to be rapidly and reliably adapted to varying operation conditions by the use of replaceable, modular pieces of auxiliary equipment etc.
