An insulation for a liquefied transport vessel 1, the vessel comprising an outer hull 2 and at least one liquefied gas tank 3 contained within the hull, the hull and tank defining an insulating void 5 between the inner surface of the hull and the outer surface of the tank wherein the void is an integral layer of the insulation apparatus, the apparatus comprising an inert gas cooling arrangement 7 arranged in use to reduce the temperature of an inert gas. The method discloses the void and the step of controlling the temperature of the inert gas and in the void below 0 degrees C. Additionally, a control system comprising an inert gas temperature control arrangement that controls the temperature of gas within the void to be below 0 degrees C is disclosed. Furthermore, a cooling system for the vessel comprises a gas heat exchanging apparatus 7 that receives a first input of boiled-off gas 8 from the tank on the vessel, and a second input of a supply of inert gas 9, wherein the heat exchanging apparatus is arranged to cool the inert gas by using the boiled-off gas and to output the inert gas at a reduced temperature.
