The Deepwater Millennium is a dynamically positioned drillship capable of drilling in water depths of between 2,468 m and 3,048 m, and as deep as 10,000m below the sea surface.
Transocean chose the port of Ngqura because it is on the direct path of the Deepwater Millennium’s final destination in Mozambique, and also because it has a draft of 16 m, which is suited to the vessel’s minimum required depth of 15 m. “Transocean was amply satisfied with the facilities made available by DCD Marine to undertake the required modifications,” says Gerry Klos – General Manager of DCD Marine, adding that work on the vessel started on November 16, 2011.
The project included the manufacture and installation of new lifeboat davits and the lifeboat platforms, the painting and coating of the decks and the installation of temporary living quarters (TLQ). DCD Marine also installed a reverse osmosis system for the supply of fresh water, and a High Precision Acoustic Positioning (HiPAP) valves. It also replaced sea valves and pipes. According to MarineLog Online, a total of 372,571 work hours were clocked, including 110,751 by DCD Marine’s employees; 98,428 hours from DCD-appointed sub-contractors and 163,392 hours clocked by Transocean and Transocean-appointed sub-contractors
