Installation (1) for VOC-recovering and shielding gas protection of tanks (2) and connected devices on board a tanker, said installation comprising a first installation section (3) that normally is in operation for shielding gas protection and VOC-recovering and a second installation section (4) based on use of the inert gas (IG), which in substance is gaseous combustion product from the tanker's boilers/turbines and motors or gas from an inert gas generator, which second installation section functions as a back-up installation that normally is not in operation except for freeing the tanks (2) from gas. The first installation section is based on use of hydrocarbon (HC) gas and comprises: at least one VOC-recovering plant (5) connected to, at least one HC-storage (6) connected to, at least one HC-gas preparation device (7), devices for fluid communication (8) for HC-gas transport between the HC-storage and the tanks of the ship, devices (9,10) for fluid communication within the installation, internal on the ship and to/from an external installation (10), a control device (11) for operation of the installation according to pressure, volume, level, composition, temperature or flow within or through the components of the installation. A method making use of the above-mentioned installation is also a part of the invention.
