Constituent Parts of the System

Launch Platform Odyssey

A self-propelled semi-submersible, catamaran-type, Launch Platform (LP) Odyssey is a floating rocket launch system. The platform is based on an off-shore oil drilling rig and was built at Rosenberg shipyard (Stavanger, Norway). It is equipped with a launch pad, a launch vehicle erector, systems for filling with propellant components, and other systems that support the integrated launch vehicle pre-launch processing and launch. The installation of the rocket systems, launching and support equipment was performed at the Kvaerner-Vyborg shipyard at Vyborg (Russia).

The platform has a hangar, inside which a launch vehicle Zenit-3SL integrated with the payload is transported to the launch site. The hangar has an air conditioning system which operates throughout the entire transit period. There is a special transporter/erector to roll the launch vehicle out of the hangar and erect it on the launch pad. There are rooms equipped for propellant component storage (kerosene and liquid oxygen). A remotely-controlled rocket fuelling system and an automatic launch system allow to conduct pre-launch operations without any persons present on board the platform.

LP can accommodate 68 persons of crew and launch support personnel.The accommodations include living quarters, a canteen, and an ambulance room.

The home port of the launch platform is Long Beach port located in south-western US (California).

The vessel arrived from Europe to the Home Port under its own power by way of Gibraltar, Suez channel and Singapore.
