The discussion covers the need for large tanker loading and mooring equipment caused by the advent of giant tankers; the usefulness of single-point mooring buoys in oil-producing zones where no port facilities are available and their limitations (by marine and climatic conditions) in other areas; single-point mooring piers consisting of a rigid vertical structure rotating freely around a pivoting point anchored on the sea floor, developed for open and deep-sea use and virtually immune to rough seas, winds, and currents; tests conducted on a reduced-scale model, showing that stresses caused by a moored tanker in 4 m avg (7 m max) seas are within acceptable limits; and other advantages of such mooring piers, e.g., minimum relative oscillation between pier and ship, loading in agitated seas, high allowable pumping rates, and mechanically performed connection to tanker manifold.
