A tank for storage of hydrocarbon liquids on the seabed, being of double hull construction which is compartmented to form a plurality of chambers, such that the tank may be safely towed from its build location or shipyard, to offshore deployment location as marine warranty compliant vessel, having appropriate intact and damaged stability characteristics. There is also provided a method for deploying a tank for storage of hydrocarbon liquids on the seabed, the method comprising the step of towing the tank having un-ballasted storage areas and compartments to the location of deployment; flooding at least partially the storage area to achieve substantial neutral buoyancy of the tank to allow decent of the tank up to a submerged equilibrium; allowing decent of the tank to the seabed and injecting air into at least one compartment for maintaining equilibrium between the pressure applied by the surrounding sea and the pressure inside compartments and storage area. |
