Background:

Buoy-based systems must be moored to ensure they remain stationary. Buoys are usually mooring with stainless steel mooring lines, bottom chains, and anchors. It is recommended that the buoys be moored at the deepest part of the channel to ensure the most inclusive measurement. This allows for multiple measurements of depth and best reflects the characteristics of the entire body of water. Buoy-based systems are usually moorings either single or two-point moorings depending on the environment and application-specific factors. JXCT's floating water quality monitoring system can help monitor the water quality of rivers and lakes.

Single point mooring

Single point mooring data buoy. Single point moorings are uncommon, but they require minimal mooring equipment. The device can be deployed in very calm waters with minimal instrumentation. Single point mooring should only be used when all sensors and equipment are installed in instrument cages or deployment tubes. Hanging sensors are at risk of damage or entanglement with anchor lines. Cages or pipes protect the instrument from entanglement, underground debris, and electrical currents without affecting sensor readings.

In a single point configuration, the mooring line connects the buoy directly to the bottom chain and anchor. The sensor is usually mounted in a central deployment pipe or connected to a rigid instrument cage. Anchors, bottom chains, and mooring lines are assembled and attached to buoys before the system is deployed.

Two point mooring

Data buoy with two points mooring. Two-point mooring is the most common deployment configuration. This is the recommended setting if the sensor will be suspended at multiple depths in the water column. In a two-point setup, the mooring line is pulled away from the data buoy by two smaller marker buoys. This configuration allows the column of water below the buoy to be used for sensors without the risk of entanglement with the anchor line. It also provides higher stability if there is current or wave action at the location.

Two-point moorings require a larger deployment area than single-point moorings because marker buoys are usually set about ten feet away from data buoys. Additional mooring lines extend from marker buoys to bottom chains and anchors on the seafloor. The added system stability of the two anchor points is well worth the additional equipment, as is the extended area of the suspension sensor.

floating water quality monitoring system

The large-scale water quality monitoring system floating station is an intelligent monitoring equipment that can adapt to marine monitoring operations. The floating water quality monitoring equipment can float on the sea for a long time to monitor the water quality environment in real time.
