ABSTRACT:
A mooring system is provided, of the type that includes several chains extending in loose curves from a mooring buoy at the sea surface to spaced anchor locations at the seabed, which enables the buoy to deflect sidewardly by a further distance and to absorb more energy during such deflection than heretofor, particularly in shallow water mooring. The system includes an anchoring device which holds the lower end of a chain at a level raised high above the sea floor when the chain is pulled taut, while allowing the lower end portion of the chain to lie at a lower level such as at the sea floor when the chain is loose. One system includes an arm having an inner end pivotally mounted near the sea floor and an outer end connected to the lower end of the chain, so that tension in the chain pivots up the outer end of the arm to thereby raise the lower end of the chain.
