For a Canadian oil drilling company, our e-loop energy chain solution ensures that the top drive, which lowers the drill pipe into the earth and pulls it out again, is always safely and reliably supplied with energy and signals, even after heavy storms. The energy chain replaces the service loop previously used.
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 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.
Heavy-duty CAL-series Liebherr rotary cranes are used on installation ships for offshore wind turbines. They can lift components weighing up to 1,500 tons. Energy transfer through the slewing ring is ensured by an innovative concept connecting two energy chains, allowing the boom to rotate up to 900 degrees.
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.
