Installation and decommissioning vessel

Pioneering Spirit

Pioneering Spirit, the world's largest offshore construction vessel. In 2005 Vuyk is contracted by Allseas to assist in performing the structural design of the decommissioning vessel Pioneering Spirit (Pieter Schelte). Main challenge in this exciting project is developing a structural design method suitable for this extraordinary large vessel together with Lloyd’s Register as rules are not compatible with the vessel.



Due to lack of rules, together with Allseas, we had to define the waves to be used for the design since the rules were not sufficient. This has proven and further strengthened Vuyk’s expertise in global and detailed calculation methods for wave loads (3D diffraction AQWA), bending fatigue, typical problems with thick plates, high strength materials and design of structural details to solve problems in highly loaded area’s (FEM).

In the period between 2005 and 2016 Vuyk determines the full scantlings for the hull and deckhouses and performs mechanical engineering work for stinger and topside equipment.
