A supporting arrangement for a vessel for counteracting compressive loads at an operating temperature. The supporting arrangement also provides inertial stiffening of the hull of the vessel as well as acoustic and vibration damping. The supporting arrangement includes a support structure that is made from a shape memory alloy that contacts and presses against the inner walls of the vessel. The supporting arrangement utilizes the shape recovery properties and/or the internal energy properties of the shape memory alloy support structure to provide reinforcing and damping forces.
