Jurong Shipyard Builds Singapore’s Largest Harsh-environment Ultra-deepwater Semi-submersible SeaDragon I

Jurong Shipyard, a wholly owned subsidiary of Sembcorp Marine, has achieved a key milestone with the construction success of SeaDragon I, the largest ultra-deepwater semi-submersible drilling rig to be completed in Singapore.

SeaDragon I, the first of two identical Moss Maritime CS50 MK II design ultra-deepwater dynamic positioning (DP3) semi-submersible units ordered by SeaDragon and managed by Vantage, was christened in a ceremony in Jurong Shipyard on Friday, November 5, 2010 by Lady Sponsor Mrs Karen Dawson-Smith, wife of Mr Guy Dawson-Smith, Project Manager of SeaDragon Project.

One of the largest ultra-deepwater 6th generation semi-submersible rigs capable of working in harsh-environment conditions, SeaDragon I marks a landmark achievement for Jurong Shipyard being the yard’s first harsh-environment semi-submersible project and the first of its class to be built up from a six-column bare-deck hull. Designed for versatility and flexibility, the rig has the ability to drill 35,000 feet and operate in up to 10,000 feet water depth, with an accommodation capacity for 192 persons.

Following the naming, the rig will complete final commissioning and acceptance testing before its scheduled delivery in early 2011.

Mr George Sutherland, Technical Director of SeaDragon, said: “We are very pleased with the progress made to date and are looking forward to taking delivery of SeaDragon I early next year. Jurong Shipyard’s rig building capabilities and strong management expertise have played a vital role in the successful completion of this project and SeaDragon would like to congratulate everyone in the Jurong Shipyard team in the achievement of this significant milestone.”

Mr Paul Bragg, CEO and Chairman of Vantage Drilling, said: “I would like to thank Jurong Shipyard’s construction team for your outstanding work and cooperation. Your workmanship and professionalism are on display and you have distinguished yourselves as world-class builders.”

Mr Wong Weng Sun, President and Chief Executive Officer of Sembcorp Marine and Managing Director of Jurong Shipyard, said: “We would like to thank SeaDragon for their vote of confidence in selecting Jurong Shipyard to outfit their two new semi-submersible rigs. Jurong Shipyard is proud that this Moss Maritime design ultra-deepwater rig will provide another industry solution to oil and gas companies when it comes to rigs selection. When delivered, SeaDragon I will add to Vantage’s stable of high quality and modern rigs. We had previously completed and successfully delivered rigs of Friede & Goldman ExD and Bingo 9000 designs. We will continue to build competencies in this segment to prepare for future opportunities.”
