SYNOPSIS: The 5,930-ton American drilling ship, "Glomar Java Sea" was owned
by Global Marine of Houston, Texas, and leased to Atlantic Richfield Company
(ARCO). In the fall of 1983, the vessel was on duty about 200 miles east of
the Vietnamese coast. The ship was drilling for oil in the South China Sea
in a joint venture of ARCO and China Naitonal Offshore Oil Corporation, a
state-owned concern.
The "Glomar Java Sea" is a sister ship of the "Glomar Explorer," which,
under the guise of being utilized by the late Howard Hughes in a deep sea
mining operation in the Paficic, was really being used by the CIA and Navy
in a $350 million project to retrieve a sunken Soviet Golf-class submarine.
A large part of the submarine was in fact recovered in 1974 before details
of the project were publicly revealed.
Documents removed from the ship by a crewman before the disaster indicate
that the vessel was being shadowed by armed Vietnamese naval craft and that
there were submarine mines beneath the "Glomar Java Sea," placed there and
retrievable by its crew. Another document indicates that the ship was
damaged prior ot the typhoon when a Chinese supply boat rammed into its
side, causing some $320,000 damage to the vessel. The Glomar Java Sea did
not leave its post for repairs.
Communications between ARCO and Global Marine, as well as telegraphic and
radio communications of the U.S. Western Pacific Rescue Coordination Center
(WESTPAC) reveal information about the search for the crew of the Glomar
Java Sea.
The documents indicate that a number of survivors from the stricken vessel
were floundering in the water off the coast of Vietnam for hours after the
disaster. There is also indication that the men were picked up by Vietnamese
coastal patrols and are held captive of the Hanoi regime.
