ABSTRACT:
The offshore facility and terminal includes a plurality of underground salt caverns located beneath the ocean floor. An offshore platform is located above the caverns and includes a flow line to a single point mooring for connection to a supertanker. A well extends from the platform into the underground salt caverns for the flow of hydrocarbons. The hydrocarbons are stored in the underground salt caverns with an immiscible displacing fluid, such as brine. The hydrocarbons and brine are immiscible and have different densities such that the brine settles at the bottom of the underground cavern. Another well extends from the underground cavern to a displacing fluid reservoir. This reservoir is a brine pond located in a depression in the ocean floor. The brine is pumped to and from the brine pond and into the underground cavern to assist in the off-loading and removal of the hydrocarbons.
