A mooring buoy assembly includes a floating structure, a pipe, an elbow, and a swivel joint. The pipe extends vertically into and away from the floating structure, and is fixed to the floating structure such that the floating structure does not rotate with respect to the pipe. Furthermore, the pipe is configured to provide a flow path in fluid communication with a submerged hose. The elbow is in fluid communication with the pipe and provides a change in direction of the flow path. Furthermore, the elbow is supported by the floating structure and is configured to be in fluid communication with a floating hose. The swivel joint is connected to the pipe and is configured to allow the elbow and floating hose to rotate relative to the submerged hose.
