Buoy Deployment Guide

Note this guide is in two sections to be used if on a large ship, if using a small vessel 
the two sections need to be merged.


1.	Pre-departure:  Check the coordinates for the site and discuss the deployment 
	procedure and safety concerns with bridge and deck crews.  

2.	Arrive on site. 

3.	Survey deployment site for hazards, depth, as well as for ocean conditions and ships drift.

4.	Fall off the drop site and line up to deploy the mooring while moving upwind and/or up-current 
	to the mooring site (this keeps the buoy and mooring line away from the vessel during deployment).

5.	Communicate to deck personnel when the ship is approximately twice the length of the mooring away 
	from the drop site for a shallow mooring (less than 300 feet) or about 1.5 times for deep mooring; 
	the ship should also be headed to the drop zone at this time.

6.	Hold position and heading as the buoy is transferred overboard.  Depending upon conditions it may 
	be necessary to make way toward the drop site if position cannot be held.

7.	Once overboard slowly steam (2 to 3 knots) to the drop site.  The deck crew will pay out the 
	mooring at this time.

8.	As the drop site is approached give a count down to the deck crew so that the anchor can be dropped 
	as close the targeted coordinates as possible.  If the mooring has not been payed out fully by the 
	time the drop site is reached make a gradual circle that will come back to the site and then repeat 
	the count down.

9.	After the drop move clear of the drop site, but stay in the area to assure that all went well with 
	the deployment.


1.	Call CDIP to check in and make sure the buoy is properly communicating.

2.	Assure buoy is attached to mooring and double check all mooring connection points for tightness and 
	the presence of cotter pins.

3.	Rig buoy to the release mechanism (this may vary from a quick release to simply sliding the buoy down 
	a ramp or off the side of a small craft).

4.	If lifting with an A-frame, crane or davit rig a line in the one corner of the triangle to assure that 
	the buoy does not spin while it is being lifted!  Spinning the buoy can damage its sensors.  It is 
	easiest to use a long line and hold both ends to stop spinning.  You can then release one end of the 
	rope once the buoy is in the water to recover this line.

5.	Let the bridge know the buoy has been released and start paying out the line.  Do not place any personnel 
	in pinch and crush points and pay attention to inline floats and sinkers while deploying the line.

6.	Once the line is payed out communicate the bridge that you are ready to put the anchor over-side.  
	(In some cases the anchor may already be rigged on the outside of the ship).

7.	Rig the anchor with a quick release or ready the release chute and deploy once onsite.

8.	Check to make sure the buoy deployed well.  Note how it is riding in the water after the anchor is on the 
	bottom.  Check buoy finder to look at wave and location data.  Call CDIP to assure communications between 
	the buoy and the network are working.
