Hitachi Zosen recently received an order from National Drilling Company (NDC), Abu Dhabi of the United Arab Emirates, to construct a cantilever type jackup offshore oil drilling rig. The rig is the fourth of the same kind to be constructed by Hitachi for NDC—a subsidiary of the state-run Abu Dhabi National Oil Company (ADNOC).
The former three rigs, two cantilever types and one slot type, were completed between December 1979 and April 1980. They were constructed at the Ariake Works.
The rig of this latest order will be constructed to almost exactly the same specifications as the other three rigs, except that it will be able to operate in water depths about 15 meters deeper than the others. It will be constructed at the Ariake Works also, for delivery in February 1982.
