Tetrahedron is set to build a prototype crane together with its consortium partners, consisting of Jack-Up Barge, TNO, Shell and GE.Tetrahedron has come up with a patented type of crane design that can lift higher than a conventional luffing boom crane on the same foundation. The 130 metre tall prototype will be built to measure key aspects of the Tetrahedron crane’s structural behaviour, verify the design and test its resilience against phenomena such as crane-deflection and a sudden loss of load. The crane can be installed on existing jack-up vessels.
