Abstract
Abstract A turret type mooring for a seagoing vessel, such as an oil tanker, is disclosed. The mooring includes a fluid swivel joint which is formed in the bow of the vessel for loading and unloading oil or other fluid to or from the vessel. The mooring is disposed within a watertight compartment and can be accessed for repairs, maintenance and monitoring purposes from within the vessel so that external access beneath the waterline is not required and the mooring can be serviced without taking it or the vessel out of operation.
