A jack-up type of offshore oil-drilling platform is adapted for rocket launching, wherein the rocket is assembled on a mobile launch pad in a protected on-shore facility then loaded onto the floating jack-up barge for transport to a launch site miles offshore. The barge is jacked up to create a stable, sea-bottom supported structure; a particular feature is the used of a movable cantilever structure on which the rocket and its supporting pad are loaded while in the on-shore facility, then this structure is moved to a central location on the barge, the barge is floated, and the floating barge is towed to the launch site. At the launch site the structure is moved back to a cantilevered position for launch. In this manner the exhaust gasses from the rocket motors can be directed harmlessly into the sea.
