Synchronised stability ... Instead of the more typical pair of floating cranes, only one was available to place the 600t superstructure onto a ship being built for the New Zealand Navy

摘要

The Tenix is a multifunctional support and troop transport ship for the New Zealand Navy currently being built at Merwede Shipyard in Hardinxveld-Giessendam. The ship's superstructure weighs more than 600t. Placing this to precise geometric tolerances would normally require two cranes or floating derricks. As Johan van Vuuren, project manager at Merwede Shipyards, explains: "The weight is no problem for a single crane. It's the volume that makes it awkward. You could compare it to lifting a flexible cardboard box. That's why we designed the construction for hoisting using two cranes."
