heal.abstract	In the European project ""Surfacing System for Ship Recovery"" (SuSy), gas inflated balloons are envisaged to be used for providing reserve buoyancy to damaged ships for the purpose of preventing ship capsizing and/or sinking, along with lifting wreckages from the seabed. The external application of a SuSy device on an Aframax Tanker that has been structurally compromised is studied, using the finite element method and following the IACS CSR rules for Tankers. A damage condition is assessed, where the middle compartment is compromised on the starboard side and the Tanker is heeling. The damage condition is simulated using a three compartment finite element model along with a simulated damage on the middle compartment. The residual hull girder strength is evaluated and compared to the undamaged case. Subsequently reserve buoyancy is introduced on the damaged side of the Tanker, in terms of attached balloons on the outer hull of the vessel, for the purpose of bringing the ship to an upright position. The effect of the forces exerted from the attached balloons on the vessel is studied, considering global ship strength. The global ship strength is evaluated considering the most suitable areas for attaching the balloons aimed at lowering the stress peaks that appear on the damaged compartment of the vessel. ©2011: The Royal Institution of Naval Architects.	en
