Jacket Lifting System of the Pioneering Spirit
The story of this project
Pioneering Spirit (formerly Pieter Schelte) is the largest construction vessel in the world, designed for the single-lift installation and removal of large oil and gas platforms and the installation of record-weight pipelines.
With new mission equipment to be installed on the vessel, the Jacket Lifting System, Pioneering Spirit will be able to handle jackets for a.o. topside for both removal and installation.
The Jacket Lifting System consists of two beams capable to handle jackets up to 20.000 tons. The beams will rotate with bearings capable to handle the load of the jacket and the beams itself, in adjustable degrees to align to the jackets. Additional demands for the bearings are that they must be maintenance free and safe for the environment.
Due to the smart innovative bearing design with D-glide® the 170 meter beams can be lifted at two sliding bearings of 1300 mm diameter each. Side effect is that the bearings are cost effective in purchase and maintenance.
