Mooring load monitoring

Strainstall's mooring load monitoring system, MoorAlert™, enables safe and efficient mooring of a vessel to its berth and ensures continued security.

The mooring monitoring system provides an accurate indication of loads in multi-line mooring configurations and provides data that will protect the performance of the line. Loads are monitored in real-time by load measuring pins installed into quick release mooring hooks, enabling each mooring line to be pre-tensioned to acceptable values of load.

Strainstall can also provide simple, portable systems for vessel owners who wish to monitor mooring line loads but are docking at terminals without an integrated mooring load monitoring facility, typically comprising of wireless load shackles and a display.

MoorAlert™ mooring load monitoring benefits:

• Maintains safe and efficient mooring line tension
• Ensures safety of personnel whilst vessel is moored
• Protects jetty equipment and infrastructure

MoorAlert™ mooring load monitoring features:

• Real-time monitoring of tensions in the mooring lines during unloading/loading
• Indication of the position of the quick release hook (open or closed)
• Alarms in the event of parameters being outside of operator-settable limits
• Remote release of quick release hooks
• Emergency release of quick release hooks

How Strainstall's MoorAlert™ mooring load monitoring system works:

The forces generated by a vessel on the mooring lines due to wind, tide, surge and currents can become extremely high, resulting in progressive failure of the mooring lines and potential damage to the loading arms, access gangways and jetty infrastructure.

Mooring lines are pre-tensioned to acceptable values of load with Strainstall's load measuring pins, which detect any deviation from these defined values and provide the data that will protect the performance of that line.

The signals from the load pins, together with the hook status sensors (open or closed), are consolidated by a network interface unit mounted in the hook motor starter enclosure, situated at the rear of the hook base. This unit allows the digital signals from all the hooks to be transmitted over a simple two wire network back to the jetty control room.
