A floatable twin carcass hose has a main carcass surrounded by a secondary carcass adapted to expand radially if pressurized fluid leaks through the main carcass to between the two carcasses. There is buoyancy material around the secondary carcass, an outermost cover layer, and inextensible hoop reinforcement between the secondary carcass and outer cover at one or more localized positions along the length of the hose thereby locally to inhibit expansion of the cover if fluid leaks to between the carcasses. |
