THE MOORING OF A TANKER TO A SINGLE POINT MOORING BY A RIGID YOKE

The rigid arm or yoke type Single Buoy Mooring (SBM) system is replacing the conventional SBM system as the oil field storage mooring. Since 1973, fourteen yoke type SBM systems have been ordered. The popularity of this type of tanker mooring is accelerating. In 1977 alone, five new systems were ordered. To date, four types of yoke systems have been developed to the building stage. Yoke moored tankers installed vary in size from 54,000 DWT to 167,000 DWT. Total tonnage for all systems combined in use and on order exceeds the 1.3 million DWT mark. Rigid arm moorings have been installed in water depths ranging from 140 feet to 400 feet, and maximum wave heights from moderate to as high as 52 feet. A design has been completed for the yoke mooring of a VLCC in the North Sea. This paper describes and catalogues the various types of yoke SBM systems installed or under fabrication. The application, characteristics, and component buildup will be discussed. Operational properties and fields of application of yoke moored tankers will be reviewed. Some general design aspects will be mentioned.
