L/P Odyssey is a self-propelled semi-submersible mobile spacecraft launch platform converted from a mobile drilling rig in 1997.

The vessel is currently used by Sea Launch for equatorial Pacific Ocean launches. She works in concert with the assembly and control ship Sea Launch Commander. Her home port is the Port of Long Beach in the United States.

In her current form, Odyssey is 436 feet (133 m) long and about 220 feet (67 m) wide, with an empty draft displacement of 30,000 short tons (27,000 t), and a submerged draft displacement of 50,600 short tons (45,900 t). The vessel has accommodations for 68 crew and launch system personnel, including living, dining, medical and recreation facilities. A large, environmentally-controlled hangar stores the rocket during transit and then rolls it out and erects it prior to fueling and launch.

History

Ocean Odyssey in her original drilling rig configuration

The platform was built in 1982 for Ocean Drilling & Exploration Company (ODECO) by Sumitomo Heavy Industries. It drilled its first exploratory hole about 40 miles (64 km) south of Yakutat for ARCO Alaska, Inc. The rig cost about US$110 million to build during the early eighties oil "boom".

During construction the vessel was called Ocean Ranger II, and was renamed Ocean Odyssey after the Ocean Ranger capsized with all hands lost during a storm off Newfoundland on February 15, 1982.

When built, Ocean Odyssey was classed +A1 +AMS by the American Bureau of Shipping for unrestricted worldwide ocean service. She was a 390-foot (120 m) long, 226-foot (69 m) wide, twin-hull design with a 12,450 hp (9,280 kW) propulsion system. The rig's structure was designed to simultaneously withstand 100-knot (190 km/h) winds, 110-foot (34 m) waves, and a 3-knot (5.6 km/h) current. The derrick was fully enclosed with a heated drill floor permitting operations down to −35 °C (−31 °F).

The rig had other advanced extreme-condition features as well. For example, the rig's columns were strengthened to withstand some ice impact and the marine riser had a feature similar to a cow-catcher to keep floating ice off the marine riser that connected the rig to the well on the ocean bottom.

1988 North Sea gas blowout

On September 22, 1988, Ocean Odyssey suffered a blowout while operated by Diamond Offshore Drilling on hire to ARCO (now a subsidiary of BP), drilling the 22/30b-3 well on a prospect in the North Sea.^[1] The ultimate direct cause of the incident was a failure of the subsea wellhead equipment after a prolonged period of well control.^[2] During the resulting fire the radio operator, Timothy Williams, was killed. He had been ordered from the lifeboats and back to the radio room by the rig's manager, who failed to countermand the order when the rig was evacuated.^[1]

Launch platform conversion

Ocean Odyssey spent the next several years as a rusting hulk in the docks of Dundee, Scotland. Her availability prompted Boeing to establish the Sea Launch consortium, for which she was bought in 1993 by Kværner Rosenberg of Stavanger, Norway, and renamed L/P Odyssey.

From late 1995 to May 1997, Kværner extended the length of the platform and added a pair of support columns and additional propulsion systems. The upper deck — the location of the former drill floor — was rebuilt to accommodate the launch pad and launch vehicle service hangar. In May 1997, Ocean Odyssey arrived at Kværner Vyborg Shipyard for the installation of the launch vehicle equipment itself.

By 1999, the vessel was ready for service, and on March 27, 1999, a Zenit-3SL rocket successfully launched a demonstration satellite to a geostationary transfer orbit.^[3] The first commercial launch occurred on October 9, 1999, with the orbiting of the DirecTV 1-R satellite.^[4]

2007 launch failure

On January 30, 2007, a Zenit-3SL carrying the NSS-8 satellite failed to launch and exploded aboard Odyssey. There were no injuries. Damage to the launch platform was mostly superficial, though blast deflectors underneath the platform were knocked loose and lost when they fell into the sea.

Odyssey returned to service with the January 15, 2008, successful launch of the Thuraya 3 satellite.^[5]
