CB-450 Deployment 

Single point mooring 
 

Single-point moorings are used in calm waters when monitoring sensors are 
attached to the instrument cage or housed in deployment pipes. The sensors 
are thus protected and less vulnerable to damage caused by subsurface debris, 
high currents, and entanglement from anchor lines.  
 
In a single-point configuration, a stainless steel mooring line connects the buoy 
directly to a bottom chain and anchor. At normal pool/stage, the mooring line 
should be taut, with most of the bottom chain resting on the seafloor. As the 
water level increases and the buoy rises, the bottom chain is lifted from the 
floor. 

 

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.
