Caspian gets new drilling capacity
NATIONAL Iranian Oil Company (NIOC) has launched its home-built semi-submersible drilling rig, Iran Alborz, at the Sadra Shipyard in Nekkairan, on the Caspian Sea coast. NIOC claimed the rig cost just $80million to build, but that, had it been built abroad, the cost could have been as high as $450million.
