Abstract
A modular offshore hydrocarbon production storage, and loading system, which includes an assembly of cylinders rigidly connected together, with the cylinders including at least one metal floatation cylinder adapted to occupy a vertical position in use. A bottom of the cylinder is situated below a level of the water and a floatation cylinder surrounded by several metal peripheral cylinders which descend below the floatation cylinder. The peripheral cylinders include metal oil storage cylinders, with the storage being effected on a water column communicating with the water surrounding the system, and metal balast cylinders or parts of cylinders filled with oil, water, air or inert gas.
