The Shell Courses window allows users to modify parameters for each shell course.
Shell Course ID – Displays shell course’s identification number.
Start Angle – Specifies shell course’s first plate start orientation angle.
Height – Specifies shell course’s height.
CA – Specifies shell course’s corrosion allowance.
JE – Specifies shell course’s joint efficiency.
Shell Course Material – Specifies shell course’s material.
Min Yield Strength – Displays shell course’s material minimum yield strength.
Min Tensile Strength – Displays shell course’s material minimum tensile strength.
Product Design Stress, Sd – Displays shell course’s material product design stress (Sd).
Hydrostatic Test Stress, St – Displays shell course’s material hydrostatic test stress (St).
Erection Shell Thickness – Displays shell course’s required erection thickness.
Design Shell Thickness – Displays shell course’s required design thickness.
Hydro Test Shell Thickness – Displays shell course’s required hydro test thickness.
Ext. Press. Shell Thickness – Displays shell course’s required external pressure thickness.
Required Shell Thickness – Displays shell course’s required overall thickness.
Actual Shell Thickness – Specifies the shell course’s actual thickness.
Nominal Shell Thickness – Displays the shell course’s nominal thickness greater than the overall required thickness.
Shell Thickness Check – Displays shell course thickness check.
Impact Test – Specifies shell course’s material impact test requirement by the user.
Use Extra Thickness – Specifies shell course’s option for using extra thickness for calculations (only for Variable-Design-Point method).
Set Default Angles Button – Set default shell courses start angles.
Set Default Shell Values Button – Set default shell values using the input values from Shell Tab in the Design Panel. Tank shell actual thickness is set to the minimum nominal thickness that passes the Shell Thickness Check.
Equal Height Courses Button – Set all shell courses to have the same height. Tank shell actual thickness is set to the minimum nominal thickness that passes the Shell Thickness Check.
Set Min Nom Thickness Button – Set the shell course’s actual thickness to the minimum nominal thickness that passes the Shell Thickness Check.
Calculation Method – Specifies the shell calculation method. It supports two methods: the 1-Foot Method, and Variable-Point-Design Method.
Cancel Button – Exit window without performing changes.
OK Button – Exit window saving changes.
