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

Embodiment Construction

[0030] According to the attached Figures 1 to 4 , the energy guiding device according to the invention is designed as an energy guiding chain 1, which is used to accommodate different supply lines 2, such as cables, hoses and other lines. The energy guide chain 1 shown in the figures is envisaged for supplying drill bits for underwater use in offshore areas. This type of drill bit works in a tube that stands on the ocean floor. The drill bit is sunk into the tube, and the tube follows the drill bit to the sea floor. Such drilling operations are performed in particular to construct foundations for offshore wind turbines. The energy guiding chain according to the invention is intended to be used to guide the power supply lines required to operate the drill bit from the vessel or working platform to the drill bit.

[0031] according to figure 1 In the practical example shown, the energy guide chain 1 comprises two load cables 3 which absorb the entire load.

Abstract

The invention relates to an energy supply device for supply lines such as cables, hoses and other lines, particularly for supplying machines in the offshore field which are used under water, such as for supplying drill heads which drill substantially vertically downward. The essential novel features according to the invention are that the energy supply device is designed as an energy supply chain (1; 15), the energy supply chain (1; 15) has at least two parallel load strands (3; 16) having tabs (4; 17) arranged consecutively, the tabs (4; 17) are made of flexible, water-resistant material and are permanently connected together with the adjacent tabs into a load strand (3; 16) via coupling elements (5; 18), at least one respective tensile-resistant, water-resistant cable (6; 20) is guided through each of the load strands (3; 16) extending over the entire length of the energy supply chain (1; 15), the load strands (3; 16) formed from the tabs (4; 17) are connected to one another by cross-bridges (7; 19) arranged at intervals and the cross-bridges (7; 19) have 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...
