The general purpose for constructing the buoyant vessel covered within this specification is to demonstrate the feasibility of a new buoyancy control concept. The vessel is to fulfill the following performance characteristics 1 Produce approximately 1000 pounds net buoyant force as indicated on the weight-buoyancy table, using helium as the pressurizing gas. In addition to the 1000 pounds, an allowance of 160 pounds shall be included in the total weight of the vessel for the use of certain black box items to be added at a later time. 2 Construction of the pressure vessels shall be accomplished under commercial code limits with a safety factor of 3.5 to 1 to attain the operating pressure given in the weight buoyancy table. 3 The buoyant vessel shall function as a free floating, unmanned and untethered device. 4 Approximately 60 to 180 minutes will be allowed for descent to and ascent from the operating depth.
