... of the positioning system is to keep the mooring tensions at an acceptable level. It is recommended to use mean thrust, as much as necessary to keep line tensions below requirements, but not using more thrust than necessary by allowing for some of the mean load to be taken by the mooring. If required...

... controller is equivalent to frequency domain analyses where additional stiffness and damping matrices is used to represent the control system / 2 /. Mooring line dynamics are not included in the calculations, i.e. mooring line tensions are calculated as quasi-static tension. This is considered...

... Mooring line tension monitoring is required for permanently moored floating offshore platforms by some regional regulators and classification societies. This requirement is typically satisfied by installing physical sensors that directly measure the line tension. Experience shows these sensors...

...-domain simulation methods. Vibrating Wire Gauges are a potential alternative to the use of in-line load cells or inclinometers for measuring mooring line tensions. These sensors have a proven track record in the Geotechnical Industry. A sensor dedicated for the offshore industry has been developed...

These recommendations are supported and illustrated using results from time-domain analyses of three different offshore systems: two turret-moored ships and one spread-moored ship.
