Jack-up vessel Obana embarks on first project in the North Sea
The world’s largest jack-up heavy-lift vessel, Obana, has commenced its first project in the southern North Sea following delivery to its owner Petrodec.
After completing final trials, including its first offshore topside lift, Obana began decommissioning work on the Perenco UK Galahad platform (block 48/12a).
Project scope
The vessel will first remove the topside and jacket of the Galahad platform before moving on to the Amethyst field to dismantle jackets C1D, A2D, and B1D.
The work is expected to be completed and offloaded in the Netherlands by the end of the year, after which Obana will mobilize for additional operator contracts.
