Pieter Schelte is a planned platform installation/ decommissioning and pipelay vessel for the Allseas company, which when built will be the world's biggest.
Long-lead items, such as the power generation equipment and the thrusters, were ordered in March 2007. In June 2008 the high-tensile steel for the jacket and topsides lift systems were ordered. Allseas has committed to build the Pieter Schelte at a cost of US$1.7 billion. It will be 382 metres (1,253 ft) long and 117 m (384 ft) wide.
