Deep drilling rigs with top drive systems are used in the oil and gas industry. To guide cables in these systems, manufacturers and operators have so far been using so-called ‘service loops’. However, these often create problems: the cables have no guidance or defined bend radius, and can slip into the service loop or, in the worst case, break. In high winds, the freely hanging service loop can get caught in various structures and be torn off. In this situation, the complete dress pack has to be replaced, because the cables are enclosed together within the hose.
igus has developed the e-loop, a new energy chain that can safely guide cables with large cross-sections and heavy weights in hanging applications. The loop is a round, three-dimensional modular system that can move strain-relieved cables with a defined bend radius. It consists of individual chain links that have a shock-resistant outer body attachment made of PU foam and cable-friendly inner parts made of igumid high-performance, corrosion-free and chemical-resistant polymer. The loop is built around a high-tensile plastic rope that absorbs the tensile forces of the cables. The rope is composed of a synthetic plastic fibre and is therefore shatter-proof, weather-resistant, flexible and corrosion-free. The e-loop can absorb weights up to 220 kN with the rope.
When developing the e-loop, igus’s engineers focused on simple installation. The loop can be opened from the outside and filled at any time, allowing individual cables to be inserted and replaced quickly in case of maintenance. The links can also be replaced at any time. Several secured screw connections are used between the elements of the energy supply, preventing components from falling down, and increasing operational reliability.
Since deep drilling rigs need to change locations on a regular basis, the developers incorporated bolted mounting brackets that enable a quick disassembly. In addition to use on deep drilling rigs, the saltwater-resistant e-loop is also suitable for hanging applications in the offshore industry, for construction machinery, shore power or even wind turbines.
