A method for floating deployment of cylindrical components

This application provides a method for the floating deployment of a cylindrical component. First, the cylindrical component is loaded onto a semi-submersible barge, and a buoyancy device is installed on the inner side of the component. After the semi-submersible barge submerges until the bottom surface of the buoyancy device contacts the liquid surface, the air intake and exhaust pipes of the buoyancy device are opened. When the cylindrical component sinks to a preset water depth, air is pumped into the stabilization chamber through the air intake and exhaust pipes until the buoyancy device can float in the water, and then the air intake and exhaust pipes are closed. The buoyancy device is then adjusted to be coaxial with the cylindrical component; air is pumped into the stabilization chamber a second time through the air intake and exhaust pipes until the buoyancy of the buoyancy device is sufficient to lift the cylindrical component and suspend it in the water, causing it to automatically separate from the semi-submersible barge. The cylindrical component can then be towed out of the dock to the deployment position. After the gas pumped into the stabilization chamber is expelled, the cylindrical component begins to sink. After adjusting the verticality of the cylindrical component, it is finally sunk to the bottom of the substrate.
