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.
