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).
