Energy Director

Abstract

The invention relates to an energy guiding device for supply lines, such as cables, hoses and other lines, particularly for supplying machines in the offshore sector that are used under water, e.g. for supplying drill heads that essentially drill vertically downwards. The essential new features consist in that the energy guiding device is designed as an energy guiding chain (1; 15), in that the energy guiding chain (1; 15) displays at least two parallel load strands (3; 16) with consecutively arranged straps (4; 17), in that the straps (4; 17) are made of flexible, water-resistant material and permanently connected to the adjacent straps via coupling elements (5; 18) to form a load strand (3; 16), in that at least one tension-resistant, water-resistant cable (6; 20), extending over the entire length of the energy guiding chain (1; 15), is guided through each load strand (3; 16), in that the load strands (3; 16) formed from the straps (4; 17) are connected to each other by cross-members (7; 19) arranged at intervals, and in that the cross-members (7; 19) display holders (8) for receiving the supply lines (2).

Description

technical field [0001] The invention relates to an energy guiding device for power supply lines, such as cables, hoses and other lines, in particular for powering machines in marine areas used underwater, for example, for powering substantially vertical Drill bit powered down drilling. Background technique [0002] Such drilling is performed to form the foundations of, for example, offshore wind turbines. To supply power to such drill bits operating at depths of up to approximately 200 meters, permanently enclosed cable harnesses have been used so far, which are guided down from the ship or working platform to the seabed. This known technique has the disadvantage that when using enclosed cable bundles, the individual wires cannot be replaced or added in case of defect or damage to replace them with other wires or to extend them with additional wires. Furthermore, in the case of drilling very deep, the load-carrying capacity of the wires also causes problems, since the tens...

Problems solved by technology

This known technique has the disadvantage that when using enclosed cable bundles, the individual wires cannot be replaced or added in case of defect or damage to replace them with other wires or to extend them with additional wires

Furthermore, the load-carrying capacity of the line also causes problems when drilling very deep, since the tensile stress acting on the line risks exceeding the permissible limit
