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