The invention relates to an offshore platform lifting and transportation system for jacket type platforms which incorporate a flotation unit 1 and a stabilisation unit 2 which can be assembled in halves or sections around the platform to lift the complete platform after cutting of the jacket legs 6. Stability and structural integrity of the system are further provided by vertical columns and bracings 3 attached to the upper part of the platform with the capability to allow connection and vertical adjustment between the flotation and stabilization units by sliding or geared connections. The stabilisation unit is maintained at sea water level during lifting and transportation using tow lines 4 and a suitable towing vessel 5.
