Abstract
A steel plate and concrete composite tank unit, tank groups and offshore platforms with new type of tank units are disclosed. The tank unit comprises an outer concrete tank that comprises an outer tank shell, two heads and ring shell connections at both ends, an inner steel tank that comprises an inner tank shell, epitaxial structures at both ends of the inner steel tank. Inner tank shell is connected to the outer tank shell by epitaxial structures, and an isolation layer that is formed from the gap between the outer concrete tank and the inner steel tank where it is filled with isolation medium.
Claims19
A tank unit, comprising:
- an outer concrete tank, comprising an outer tank shell, two heads, and ring shell connections at both ends of the outer tank shell;
- an inner steel tank inside the outer concrete tank, comprising an inner tank shell, two inner heads, two epitaxial structures at both ends of the inner tank shell, wherein the inner steel tank is connected to the ring shell connections of the outer concrete tank by the epitaxial structures;
- and
- an isolation layer, being formed from a gap between the outer concrete tank and the inner steel tank, wherein the gap is filled with an isolation medium, wherein the isolation medium inside the isolation layer is one or more of:
- an inert gas, a liquid, an inert gas with a soft solid material, or a liquid with a soft solid material, wherein a system pressure inside the isolation layer is controlled.
2 more elements
A tank group, comprising:
- two or more tank units that are closely connected in parallel or in series by group connections, wherein the tank units in the tank group are arranged vertically to become a vertical tank group or arranged horizontally to become a horizontal tank group,
- wherein the tank unit comprises an outer concrete tank, an inner steel tank inside the outer concrete tank and connected with the outer concrete tank via ring shell connections of the outer concrete tank and epitaxial structures of the inner steel tank, and an isolation layer in between the outer concrete tank and the inner steel tank, wherein the isolation layer is filled with an isolation medium, wherein the isolation medium inside the isolation layer is one or more of:
- an inert gas, a liquid, an inert gas with a soft solid material, or a liquid with a soft solid material, wherein a system pressure inside the isolation layer is controlled.
An offshore platform, comprising:
- a tank group comprising two or more tank units, wherein the tank unit comprises an outer concrete tank, an inner steel tank inside the outer concrete tank and connected with the outer concrete tank via ring shell connections of the outer concrete tank and epitaxial structures of the inner steel tank, and an isolation layer in between the outer concrete tank and the inner steel tank, wherein the isolation layer is filled with an isolation medium, wherein the isolation medium inside the isolation layer is one or more of:
- an inert gas, a liquid, an inert gas with a soft solid material, or a liquid with a soft solid material, wherein a system pressure inside the isolation layer is controlled;
- a topsides, including facilities used for drilling, oil and gas production and transportation, utilities, or living, wherein the topsides is above water and located on a top of the tank group, and connected to the tank group by supported leg structures;
- and
- a positioning system or a foundation, wherein the positioning system is used with the offshore platform when the offshore platform is floating, and comprises one or more of:
- an anchor mooring system or a dynamic positioning system, wherein the foundation fixes the offshore platform on a seabed and comprises one or more of:
- a long pile foundation, a suction pile foundation, a sealing steel pile foundation, or a gravity foundation.
