CB-450 Deployment 

Two point mooring 
 

Two-point moorings are commonly used when monitoring sensors are 
deployed in the water column below the buoy. In this setup, the mooring 
lines are pulled taut away from the buoy, freeing the water column for a 
suspended sensor line.  
 
In most two-point configurations, mooring lines connect the data buoy to 
small marine marker floats, often located on the water surface. These marker 
floats are shackled to another mooring line that runs to the floor and 
connects to a bottom chain and anchor assembly. Additional subsurface 
marker floats may also be used in some applications. As in single-point 
systems, the bottom chain prevents buoy submersion as the water level 
fluctuates. 
 

Important: 

This section contains only general information on the available 

mooring options for CB-450 data buoys. To develop an effective mooring 
strategy, a variety of application-specific criteria (water level fluctuations, 
currents and wave action, debris loads, etc.) must be thoroughly reviewed prior 
to deployment. NexSens does not endorse any particular mooring strategy for 
any specific application.
