Wind Load acting on Lower Part of Vessel

Go Wind Load acting on Lower Part of Vessel = Coefficient depending on Shape Factor*Coefficient Period of One Cycle of Vibration*Wind Pressure acting on Lower Part of Vessel*Height of Lower Part of Vessel*Outside Diameter of Vessel

Wind Load acting on Upper Part of Vessel

Go Wind Load acting on Upper Part of Vessel = Coefficient depending on Shape Factor*Coefficient Period of One Cycle of Vibration*Wind Pressure acting on Upper Part of Vessel*Height of Upper Part of Vessel*Outside Diameter of Vessel

Maximum Wind Moment for Vessel with Total Height Greater than 20m

Go Maximum Wind Moment = Wind Load acting on Lower Part of Vessel*(Height of Lower Part of Vessel/2)+Wind Load acting on Upper Part of Vessel*(Height of Lower Part of Vessel+(Height of Upper Part of Vessel/2))

Thickness of Bearing Plate inside Chair

Go Thickness of Bearing Plate inside Chair = sqrt((6*Maximum Bending Moment in Bearing Plate)/((Width of Bearing Plate-Diameter of Bolt Hole in Bearing Plate)*Allowable Stress in Bolt Material))

Total Compressive Load on Base Ring

Go Total Compressive Load at Base Ring = (((4*Maximum Bending Moment)/((pi)*(Mean Diameter of Skirt)^(2)))+(Total Weight of Vessel/(pi*Mean Diameter of Skirt)))

Thickness of Base Bearing Plate

Go Thickness of Base Bearing Plate = Difference Outer Radius of Bearing Plate and Skirt*(sqrt((3*Maximum Compressive Stress)/(Allowable Bending Stress)))

Thickness of Skirt in Vessel

Go Thickness of Skirt in Vessel = (4*Maximum Wind Moment)/(pi*(Mean Diameter of Skirt)^(2)*Axial Bending Stress at Base of Vessel)

Axial Bending Stress due to Wind Load at Base of Vessel

Go Axial Bending Stress at Base of Vessel = (4*Maximum Wind Moment)/(pi*(Mean Diameter of Skirt)^(2)*Thickness of Skirt)

Maximum Bending Stress in Base Ring Plate

Go Maximum Bending Stress in Base Ring Plate = (6*Maximum Bending Moment)/(Circumferential Length of Bearing Plate*Thickness of Base Bearing Plate^(2))

Compressive Stress due to Vertical Downward Force

Go Compressive Stress due to Force = Total Weight of Vessel/(pi*Mean Diameter of Skirt*Thickness of Skirt)

Minimum Width of Base Ring

Go Minimum Width of Base Ring = Total Compressive Load at Base Ring/Stress in Bearing Plate and Concrete Foundation

Maximum Wind Moment for Vessel with Total Height Less than 20m

Go Maximum Wind Moment = Wind Load acting on Lower Part of Vessel*(Total Height of Vessel/2)

Maximum Bending Moment in Bearing Plate Inside Chair

Go Maximum Bending Moment in Bearing Plate = (Load on Each Bolt*Spacing Inside Chairs)/8

Maximum Tensile Stress

Go Maximum Tensile Stress = Stress due to Bending Moment-Compressive Stress due to Force

Moment Arm for Minimum Weight of Vessel

Go Moment Arm for Minimum Weight of Vessel = 0.42*Outer Diameter of Bearing Plate

Minimum Wind Pressure at Vessel

Go Minimum Wind Pressure = 0.05*(Maximum Wind Velocity)^(2)

Moment Arm for Minimum Weight of Vessel Formula

Moment Arm for Minimum Weight of Vessel = 0.42*Outer Diameter of Bearing Plate
R = 0.42*D_ob

What is Design Vessel?

Design vessel refers to the process of designing a vessel or a container, such as a pressure vessel, storage tank, or a reactor, that is used for storing or transporting materials at different temperatures and pressures. The design of a vessel includes determining the appropriate material and thickness, dimensions, configuration, and structural integrity to ensure safe and efficient operation under various conditions. This involves following various codes and standards such as ASME Boiler and Pressure Vessel Code, API standards, and other industry-specific regulations. The design process involves various aspects such as mechanical design, stress analysis, fatigue analysis, corrosion analysis, and material selection.
