DSV Makes Room for Rowan Viking

DSV Makes Room for Rowan Viking

Damen Shiprepair Vlissingen (DSV), part of Damen Shiprepair & Conversion, has been awarded the contract by a subsidiary of Rowan Companies Plc. to remodel the Rowan Viking.

The Rowan Viking at Damen Shiprepair in Vlissingen

The Rowan Viking is a Keppel Fels ‘N’ Class Drilling Rig. The rig, which at 124 (l) x 95 (w) x 170 (h) metres is one of the largest of its type, 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-meter legs will have to be extended to 180 metres to be able to work in the deeper Norwegian waters).

Because the leg extension work will be done at great heights, DSV has contracted Palfinger Systems to use the latter’s JUMP Systems (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-tonne leg extensions.

The crane will be more than 200 metres high (nearly four times the height of the covered dock at the shipyard in Vlissingen).

To make room for the crane, DSV has moved its warehouse, demolishing the warehouse itself and building a special foundation that can handle the high ground pressure of 30 tonnes per m² that the crane will create.

The Rowan Viking will be at the shipyard for approximately 130 days.
