Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
A method for monitoring the mooring forces in the mooring cable of a single-point mooring system for the loading and unloading of a ship wherein said ship is moored by its bow to the single-point mooring system by means of a single mooring cable in such a manner that the ship can freely swing about the singlepoint mooring system, said method comprising: measuring the tension force in said mooring cable adjacent said single-point mooring system; supplying said measured force to said single-point mooring system; transmitting from said single-point mooring system to said ship a signal representing the measured force; receiving on said ship said transmitted signal and converting said transmitted signal to a usable display; and disconnecting said ship from said single-point mooring system when said received signal indicates that said measured force has exceeded a preset value.
Claim 2
Independent Claim
138 words
A method for monitoring the mooring forces in the mooring cable of a single-point mooring system for the loading and unloading of a ship wherein said ship is moored by its bow to the single-point mooring system by means of a single mooring cable in such a manner that the ship can freely swing about the singlepoint mooring system, said method comprising: measuring the tension force in said mooring cable adjacent said single-point mooring system; supplying said measured force to said single-point mooring system; transmitting from said single-point mooring system to said ship a signal representing the measured force; receiving on said ship said transmitted signal and converting said transmitted signal to a usable display; and disconnecting said ship from said single-point mooring system when said received signal indicates that said measured force has exceeded a preset value.
Claim 3
Dependent Claim
14 words
The method of claim 1 wherein said signal is transmitted and received by radio.
Claim 4
Dependent Claim
24 words
The method of claim 2 wherein said transmission of the signal is triggered by the transmission of a signal to said single-point mooring system.
