REFRIGERATED LPG STORAGE TANK DESIGN SERVICES

Refrigerated LPG (liquefied petroleum gas) storage tanks are specialized containers designed to store LPG at low temperatures to keep it in its liquid state. Here's an overview of the various aspects related to the design of these tanks:

Design Codes & Standards: These tanks are designed in accordance with specific codes and standards established by regulatory bodies and industry organizations to ensure safety, reliability, and compliance with applicable regulations. Examples include API (American Petroleum Institute) standards such as API 620 and API 625.
Design of Shell: The shell of the tank is designed to withstand the internal pressure exerted by the stored LPG and external loads such as wind and seismic forces. The thickness and material of the shell are determined based on design calculations and standards.
Design of Roof: The roof of the tank is designed to provide structural support and prevent leakage. Various designs, such as cone roofs or dome roofs, may be used depending on factors like tank size and operational requirements.
Design of Bottom Plate: The bottom plate of the tank is designed to support the weight of the stored LPG and the tank itself. It is typically constructed to be strong and resistant to corrosion.
Design of Wind Loads: The tank must be designed to withstand wind loads to prevent structural failure or damage. Wind load calculations are performed based on factors such as wind speed, tank height, and local environmental conditions.
Design of Seismic Loads: In areas prone to seismic activity, the tank must be designed to withstand seismic forces. Seismic design considerations include factors such as soil conditions, seismic zone classification, and structural dynamics.
Anchorage Design: Anchorage systems are used to secure the tank to the foundation and prevent it from overturning or shifting during external forces such as wind or seismic events. The design of anchorage systems is critical for the stability and safety of the tank.
Design of Foundation: The foundation of the tank provides structural support and stability. It is designed based on factors such as soil bearing capacity, tank weight, and seismic considerations.
Design Calculations: Various design calculations are performed to ensure the structural integrity and safety of the tank, including calculations for shell thickness, roof design, bottom plate design, and anchorage design.
GA Drawing: General arrangement (GA) drawings provide an overall layout and dimensions of the tank, including details of components such as the shell, roof, and foundation.
Detail Drawings: Detail drawings provide more specific information and dimensions for various components of the tank, including weld details, connection details, and reinforcement details.

Overall, the design of refrigerated LPG storage tanks involves careful consideration of various factors to ensure safe and reliable operation, compliance with regulations, and protection of the environment and surrounding communities.
