The Odyssey-class Sea Launch Platform is the first component of a package of a mobile, semi-submersible launch platform at sea and its launch commander. It is a rather bare-bones design, based on a design for a semi-submersible oil rig from the 90s, capable of being remote-controlled via the Laige Network (see below).

The core and pride of the design is the capability to lift and place rockets, at sea, from the assembly bay on the Cosmos-class Sea Launch Commander onto the Rocket Deck thanks to a crane capable of lifting 7000 tons at once over a distance of 140 metres, capable of rotating 360 degrees. This crane also ensures, that the Odyssey-class Sea Launch Platform can be used for different purposes as well, for example as a Deepwater Construction Vessel. For storage and last checks of the rockets in question, a hangar is erected on the deck, accessible for the rocket with the help of a launch vehicle.

Once the rocket is loaded onto the platform and the ideal position for the launch reached, the ballast tanks are filled with up to 84,000 m³ of water rushing into the forty tanks, while, for a quicker fixation on one position, 14 additional tanks can be filled with up to 26,000 m³ of water. This increases the draught during normal transfer's 10.5 metres to 27.5 metres, which makes the vessel stand calmly even in rough sea.

Moved by ten propellers in gondolas, all capable of being controlled individually with highest precision, the Odyssey-class Sea Launch Platform can move at a speed of ten knots. They are diesel-electrical in nature, the power provided by the diesel engines also used to power the other systems of the vessel.

The Odyssey-class Sea Launch Platform is equipped with a Differential Global Positioning System and a system for dynamic positioning, which allows for holding position with utmost precision, either automatically or controlled by hand, while the responsible computer systems are double redundant. This works either with help of the sixteen anchors or without. Before ignition of the rocket, the blast shields are raised and the whole vessel vacated by the crew for security reasons, all functions can be taken over by the Cosmos-class Sea Launch Commander via Laige Network. The blast shields protect the superstructure of the platform and redirect the launch fire of the rocket into the sea, behind the vessel, akin to a fire trench on dry shore.

Once the rocket is launched, the crew can go back onto the vessel and prepare it for the next launch. This can be achieved by either helicopter, a flight deck with outdoor maintenance facilities is installed on the rocket hangar, or via dinghies, two of which will be provided. The Odyssey-class Sea Launch Platform carries the provisions to house her 70 men strong crew and a few additional passengers relatively comfortably.
