Abstract: A single anchor leg mooring and tanker cargo transfer system has a base with an anchor leg pipe shaft having a horizontally swiveling housing thereon to which are attached vertically pivoting cargo hose arms. The arms have widely spaced, parallel portions extending a substantial distance beyond the base portion for augmenting the torque applied to the swivels by the cargo hoses. The hose arms are stabilized and limited in their vertical pivoting by a balanced lever structure pivotally mounted on the base and carrying buoyancy tanks. Bumpers limit the vertical pivoting of the lever structure flexing of the hose arms secured thereto.
Abstract: A single anchor leg type single point mooring and cargo transfer buoy has a load-carrying central shaft pipe for anchoring on the sea bottom and having a plurality of structurally segregated transfer chambers about which rotatable housings are sealingly mounted. Cargo vessel piping connects with these rotatable housings which communicate with the sea floor piping through connections extending longitudinally through the central shaft pipe and through apertures in the central shaft pipe wall.
