Examples of successful applications in the offshore industry

This deep drilling system drills holes to a depth of 6,000 metres largely automatically and is a "walking unit" that can even change position. The handling system that feeds the drill pipes is supplied via E4.1 energy chains.

The long travels and the high cable weight on drilling rigs pose a cable guidance challenge. Energy chain systems such as the E4.1 series or the e-loop are suitable as a proven alternative to conventional service loops.

A particularly robust plastic energy chain operates on a Huisman multi-purpose tower aboard a drilling vessel, moving on a 40-meter route. Because it moves vertically upwards, it is very exposed to the strong wind on rough seas.

This 3000HP modular offshore drilling rig has the world's largest plastic e-chain installed on a cantilever and the drill floor. The energy chain was delivered pre-assembled, reducing assembly time and costs.

E4.1 series energy chains are used to ensure that all cables for supplying the drill floor skid are carried safely on this drilling vessel. They have a low dead weight and can easily carry additional weights of 250kg/m and more.

This jack-up rig was equipped with our E4.1 e-chains from the 800 and E4.112 series with an extension link for high additional loads. The reverse energy chain principle for the cantilever and the sliding extension link chain on the drill floor reduce the installation space required for the system.

Energy chain systems are used for such applications as equipping the fingerboard or operating the top drive. They have to bear heavy weight on the many energy and data cables and hydraulic lines.

For a catwalk on a drilling vessel, the manufacturer was looking for the right cable guidance system. He found what he was looking for in the E4/4 energy chain system made of plastic, which works robustly and durably on the sea.

In the largest offshore drilling rig to date, our offshore energy chain is used for high tensile loads. From the ship, a huge drill is lowered to the rock floor. The chain ensures a safe, stable energy supply for the drilling rig.

Inside this pipe-laying vessel, the cables for the pipe-laying and welding equipment are guided by swarf-resistant e-pipes. They prevent damage to the cables and allow safe movement, even over long travels.

Several robust E4.1-series energy chains were installed for the cable guidance to the pipe-laying tower and the tensioner on a pipe-laying vessel. Because they were delivered pre-assembled, the operator saved installation time and costs.

A rotary module with internal energy chains is used to ensure cable routing in a heavy duty crane on a pipe-laying vessel. Interlocking e-chains allow an especially space-saving design.

For this riser handling crane on a drilling vessel, our engineering team implemented a complete system consisting of energy supply systems, trough modules, and chainflex cables, from design to final acceptance.

This Ship & Yacht Engineering A-frame has pivoting kinematics that allow a 180° radius of motion. To minimise maintenance and keep the bearing points lubrication-free, the company uses plastic bearings made of the igutex TX1 material.

Safe energy supply to the adjustable crane boom was needed for two sheerleg cranes. The challenges of the heavy duty cranes were great: High cable weights (up to 45kg/m) and long travels required robust cable guidance for long-term use.
