This standard is both a design code and a construction specification.The design code is based on allowable stress principles,not on a limit state basis.1.3 Design Pressure and Temperature.Tanks designed for storage at nominally atmospheric pressure must be suitable for modest internal vacuum (negative pressure).Gas Tanker - Types,Tanks,Re-liquefaction and Cargo The maximum allowable tank design pressure in the vapour space for this type of system is 0.7 barg; (where the cargo is carried at ambient temperature),the tanks may be designed for a maximum working pressure of about 18 barg.For a semi-pressurised ship the cargo tanks and associated equipment are designed for a working pressure of Designing storage tanks - DigitalRefiningS is the tank wall material allowable tensile stress for the operating or test condition.CA is the corrosion allowance,if any.API 650 storage tanks are often designed to work at temperatures of up to 500 ambient temperature tanks Allowable Design Stresses#186;F (260 ambient temperature tanks Allowable Design Stresses#186;C).For these higher temperature designs,the allowable stress of the material decreases.
