HOUSTON – A subsidiary of Rowan Companies plc has awarded Damen Shiprepair Vlissingen, part of Damen Shiprepair & Conversion, the contract to remodel the Rowan Viking, a Keppel Fels N-Class drilling rig that is active in the North Sea.
The Rowan Viking has been contracted to explore the Norwegian Lundin oil field and will have to be converted accordingly. The work will consist of:
- Special periodic survey (certification extension)
- Acknowledgement of compliance scope (safety modifications in accordance with Norwegian law)
- Leg extension scope [the 170-m (558-ft) legs will have to be extended to 180 m (591 ft) to work in the deeper Norwegian waters]
Because the leg extension work heights, DSV has contracted Palfinger Systems to use the latter’s unique JUMP Systems. JUMP stands for Jack Up Maintenance Platform. These are platforms that can be built around, and moved up and down, the legs. Mammoet’s largest PTC cranes will be used to hoist the 120-metric ton (132-ton) leg extensions. The crane will be more than 200 m (656 ft) high (nearly four times the height of the covered dock at the shipyard in Vlissingen).
The Rowan Viking will be at the shipyard for 130 days.
