GSF Explorer, formerly USNS Hughes Glomar Explorer (T-AG-193), is a deep-sea drillship platform initially built for the United States Central Intelligence Agency Special Activities Division secret operation Project Azorian to recover the sunken Soviet submarine K-129, lost in April 1968.
The cultural impact of Glomar Explorer is indicated by its reference in a number of books: The Ghost from the Grand Banks, a 1990 science fiction novel by Arthur C. Clarke; Shock Wave by Clive Cussler; Charles Stross's novel, The Jennifer Morgue; and The Hunt for Red October by Tom Clancy.
Hughes Glomar Explorer (HGE), as the ship was called at the time, was built between 1973 and 1974, by Sun Shipbuilding and Drydock Co. for more than US$350 million at the direction of Howard Hughes for use by his company, Global Marine Development Inc. She set sail on 20 June 1974. Hughes told the media that the ship's purpose was to extract manganese nodules from the ocean floor. This marine geology cover story became surprisingly influential, spurring many others to examine the idea. But in sworn testimony in United States district court proceedings and in appearances before government agencies, Global Marine executives and others associated with Hughes Glomar Explorer project unanimously maintained that the ship could not be used in any economically viable ocean mineral operation.
Because K-129 sank in very deep water 1,560 miles NW of Hawaii, a large ship was required for the recovery operation. Such a vessel would easily be spotted by Soviet vessels, which might then interfere with the operation, so an elaborate cover story was developed. The CIA contacted Hughes, who agreed to assist.
While the ship did recover a portion of K-129, a mechanical failure in the grapple caused two-thirds of the recovered section to break off during recovery. This lost section is said to have held many of the most sought items, including the code book and nuclear missiles. It was subsequently reported two nuclear-tipped torpedoes and some cryptographic machines were recovered, along with the bodies of six Soviet submariners, who were given a formal, filmed burial at sea.
The operation became public in February 1975 when the Los Angeles Times published a story about "Project Jennifer", followed by news stories with additional details in other publications, including The New York Times. The CIA, wanting to neither confirm nor deny the story, issued the Glomar response, which set the precedent for subsequent boilerplate responses to Freedom of Information Act requests. The true name of the project was not publicly known to be Project Azorian until 2010.
Red Star Rogue (2005) by Kenneth Sewell makes the claim "Project Jennifer" recovered virtually all of K-129 from the ocean floor. Sewell states, "[D]espite an elaborate cover-up and the eventual claim that Project Jennifer had been a failure, most of K-129 and the remains of the crew were, in fact, raised from the bottom of the Pacific and brought into the Glomar Explorer".[N 1] A subsequent film and book by Michael White and Norman Polmar revealed testimony from on-site crewmen as well as B&W video of the actual recovery operation. These sources indicate that only the forward 38 feet of the submarine were recovered.
After Project Azorian
While the ship had an enormous lifting capacity, there was little interest in operating the vessel because of her high cost. From March to June 1976, the General Services Administration (GSA) published advertisements inviting businesses to submit proposals for leasing the ship. By the end of four months, GSA had received a total of seven bids, including a US$2 million offer submitted by a Lincoln, Nebraska college student, and a US$1.98 million offer from a man who said he planned to seek a government contract to salvage the nuclear reactors of two United States submarines. The Lockheed Missile and Space Company submitted a US$3 million, two-year lease proposal contingent upon the company's ability to secure financing. GSA had already extended the bid deadline twice to allow Lockheed to find financial backers for its project without success and the agency concluded there was no reason to believe this would change in the near future.
Although the scientific community rallied to the defense of Hughes Glomar Explorer, urging the president to maintain the ship as a national asset, no agency or department of the government wanted to assume the maintenance and operating cost. Subsequently, in September 1976, the GSA turned Hughes Glomar Explorer over to the Navy for mothballing, and in January 1977, after she was prepared for dry docking at a cost of more than two million dollars, the ship became part of the Navy's Suisun Bay Reserve Fleet.
Lease, sale and current status
In September 1978, Ocean Minerals Company consortium of Mountain View, California announced it had leased Hughes Glomar Explorer and that in November would begin testing a prototype deepsea mining system in the Pacific Ocean. The consortium included subsidiaries of the Standard Oil Company of Indiana, Royal Dutch Shell, and Boskalis Westminster Group NV of the Netherlands. Another partner, and the prime contractor, was the Lockheed Missiles and Space Company.
In 1997, the ship was taken to Cascade General for modifications that converted her to a dynamically-positioned deep sea drilling ship, capable of drilling in waters of 7,500 feet (2,300 m) and, with some modification, up to 11,500 feet (3,500 m), which is 2,000 feet (610 m) deeper than any other existing rig. The conversion cost over $180 million US and was completed during the first quarter of 1998.
The conversion of the vessel from 1996-1998 was the start of a 30-year lease from the U.S. Navy to Global Marine Drilling at a cost of a mere $1 million US per year. Global Marine merged with Santa Fe International Corporation in 2001 to become GlobalSantaFe Corporation, which merged with Transocean Inc. in November 2007 and operates the vessel as GSF Explorer.
In 2010, Transocean acquired the vessel in return for a US$15 million cash payment.
GSF Explorer is currently working off the East coast of India in the Bay of Bengal for ONGC.
The rig was reflagged from Houston, US to Port Vila, Vanuatu in the 3rd quarter of 2013.
