Hitachi Completes Jackup Drilling Rig For India

The jackup offshore drilling rig Sagar Vikas (shown above), ordered by the Oil and Natural Gas Commission of India, was delivered recently by the Osaka Works of Hitachi Zosen, Japan. Scheduled for operation in the oil field of Bombay High, it is the first rig built for India by Hitachi, and the eighth rig to be completed by the Japanese shipbuilder, which has nine more on order.

For the Sagar Vikas, a fixed jacking unit was adopted, doing away with the conventional jackhouse. Overall weight was thereby reduced, allowing a greater payload of supplies and materials to be taken on the rig.

It is capable of operating in water depths to 300 feet, drilling to a maximum depth of 20,000 feet, and can withstand winds up to 86 knots and waves up to 61 feet high. The drilling platform can be raised or lowered at a rate of about one foot per minute.

The three-legged platform has a length of 210 feet, beam of 194.5 feet, and depth of 23 feet, and has been built to American Bureau of Shipping classification.
