Applications Mooring Tension Measurement
Mooring Tension Measurement
Ports and terminals worldwide face the challenge of dealing with ever larger vessels and cruise ships. Also, due to climate change, more extreme weather conditions are having an impact on the levels of strain the mooring lines are subjected to. Strong wind, waves and currents mean that even when docked, ships are constantly in motion. This means the tension placed through mooring lines is changing all the time, contributing to material fatigue and reducing service life. Additionally, if one or several mooring lines experience higher tension levels than others, there is a real risk of the mooring line breaking, resulting in potential damage to the jetty and to personnel.
To ensure a vessel stays securely docked, the tension in each mooring rope must be subject to the same loading or tension, or as close to as possible. This can be achieved through the installation of a mooring tension measurement system, which continually monitors the loads on each mooring line, so that any instances of overload or underload can be identified immediately. Port operators can then alert vessel masters so that they can take prompt corrective action to evenly redistribute mooring line loads.
The mooring measurement systems that LCM Systems supply use either load measuring pins installed into quick release mooring hooks, or load shackles/load links that are installed into the mooring line structure and secured to existing port mooring facilities. The load measurement data provided is then usually fed into a PLC system, but a separate read out can be provided where appropriate (usually in smaller ports and harbours). This can also include alarms that are triggered in the event of overload situations.
