In January 2007, Allseas took the final decision to build Pieter Schelte, the
382 m long, 117 m wide dynamically positioned platform installation / decommissioning and pipelay vessel.
Pieter Schelte will have a topsides lift capacity of 48.000 t and a jacket lift capacity of 25.000 t. The pipelay tension capacity will be 2000 t, doubling the capacity of Allseas’ Solitaire and thereby surpassing her as the world’s largest pipelay vessel.
Delivery of the completed vessel is foreseen for 2013.
