API standard 650 self-anchored flat-bottom tanks shell-plate

The API 650 specification provides guidelines for the API standard 650 self-anchored flat-bottom tanks design, manufacturing, materials, installation and inspection of welded vertical and cylindrical tanks. Such containers must be on the ground and have a closed or open top.

Oil tank is an important equipment for oil storage. The common API standard 650 self-anchored flat-bottom tanks is composed of foundation, bottom plate, wall plate, top plate and accessories. The types of oil tank are various, which can be divided according to the characteristics of material, installation position, storage oil, use, appearance, structure and volume of oil tank. The commonly used materials of metal oil tank are stainless steel, carbon steel, alloy steel, etc.

The design metal temperature of API standard 650 self-anchored flat-bottom tanks each component exposed to the liquid or vapor being stored shall be the lower of the following:
a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.
b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
