Abstract
Non-pressurized fully flooded (or ‘wet’) undersea vehicles are sensitive to weight and buoyancy changes. Thus, wet vehicles as they will be referred to from here on out, need the application of both an uncertainty margin for weight and buoyancy prediction during the design development phase. Classical margin approaches for addressing risk uncertainty in surface ships or pressurized submersible vehicles do not address buoyancy uncertainty. This is primarily due to establishing and locking-in the surface ship hull or the pressure hull of a submersible vehicle early in the design. Therefore, margin approaches that address both weight and buoyancy uncertainty during wet undersea vehicle designs appear to be needed.
