In June 2010 the contract for building Pieter Schelte, the 382 m long, 117 m wide dynamically positioned platform installation / decommissioning and pipelay vessel, was awarded to the South Korean shipyard Daewoo.
Long-lead items such as the power generation equipment, thrusters and DP system were ordered in 2007. In 2008 the high-tensile steel for the jacket and topsides lift systems was ordered. The detail design of the hull was completed in May 2010.
When built, Pieter Schelte will have a topsides lift capacity of 48,000 t and a jacket lift capacity of 25,000 t. Her pipelay tension capacity will be 2,000 t, doubling the capacity of Allseas’ Solitaire and thereby surpassing her as the world’s largest pipelay vessel.
Delivery of the completed single-lift and pipelay vessel is expected at the end of 2013, ready for offshore operations early in 2014.
