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). |
