With the launch of TDU-400 jackup, a new Premium Class 400 HPHT rig, Triyards Holdings Ltd. has become one of three Singapore yards able to design and build its own proprietary jackups and self-elevating units. “The design is in the final submittal stage to ABS, and from a construction standpoint, we are getting ready to order components,” Richard Altman, senior vice president for global business development, said at a press conference Monday at the 2012 OTC. Triyards is in discussion with clients for a rig and hopes to have an order in the next three months, Lionel Lee, chairman and director, stated.
The TDU-400 is designed to capitalize on the most advanced drilling systems and equipment available today. The design can be customized to meet the disparate needs of clients without having to be continuously redesigned, thus avoiding costs associated with variation in orders. “We wanted to design something that is shipyard friendly,” Mr Altman said. “We wanted to offer a premium performance package as light weight as we could develop with a jackup.”
The jackup can withstand 100-knot winds and meets wave criteria for global utilization. Providing accomodation for up to 220 personnel, the jackup boasts leg lengths of more than 535 ft (163 meters) and can operate in water depths of up to 400 ft (120 meters). The rig is rated to 32,500 ft drilling depth with 1.5 million tons of hookload. “We’ve incorporated a 1,000-ton topdrive, which gives you more torque,” Mr Altman said, “and today’s horizontal application or extended-reach applications need that additional torque.”
