Aircraft refueling system is a refuelling equipment for aircraft, and in particular to a cellular system for refuelling long range aircraft crossing oceans. A floating refuelling station for aircraft includes at least one container hull, which is movable and a sloping platform supported by the container. The sloping platform has at least one runway thereon for take off and landing of aircraft. The container hull may be used to store aviation fuel for refuelling the aircraft, the movability of the hull may be used to orient the runway with respect to the direction of the wind and the runway has a ramp section inclined at an angle to help slow down landing aircraft and/or to help speed up aircraft taking off. The height of the runway above the sea surface needs to be sufficient to accommodate any loss of buoyancy due to outpourings of gas from the sea bed.
