Pieter Schelte

In June 2010 Allseas awarded the contract for building Pieter Schelte, its  382 m long, 124 m wide dynamically positioned (DP) platform installation / decommissioning and pipelay vessel, 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, and the detail design of the hull was completed in May 2010.
Equipment for the lift systems and pipelay system were ordered in 2011, continuing into 2012.

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 topsides lift and pipelay vessel is expected in the second half of 2014, ready for offshore operations early 2015.
The jacket lift system will follow later.

In November 2013 Allseas announced plans to build a second single-lift vessel larger than Pieter Schelte, to be delivered in 2020.
It is intended for installation and removal of the very largest existing platforms.
