When tankers first began to be converted into floating production platforms back in the late 1970s they were connected to their moorings via an external yoke or turret simply welded onto the vessel's bow.
This approach still serves well enough for units which, like the early floaters, are destined to serve in mild environments. A single turntable, added to the vessel above water level, is perfectly adequate to take the mooring loads as the ship weathervanes with the prevailing wind and waves.
