Anchoring Systems
Standard anchoring systems
Anchor sizes vary Selected based
Boom array Currents Winds
Anchor line At lest 3-5 times the
depth of water
![Page 9: Strategies and Tactics for Boom Operations](https://reader036.fdocuments.net/reader036/viewer/2022062521/56816660550346895dd9e986/html5/thumbnails/9.jpg)
Boom Angles
Key consideration for deployment
![Page 10: Strategies and Tactics for Boom Operations](https://reader036.fdocuments.net/reader036/viewer/2022062521/56816660550346895dd9e986/html5/thumbnails/10.jpg)
Strategy
Identify location & trajectory of spill
Identify, prioritize & select sensitive areas
Select configuration
Mobilize to location & deploy
![Page 11: Strategies and Tactics for Boom Operations](https://reader036.fdocuments.net/reader036/viewer/2022062521/56816660550346895dd9e986/html5/thumbnails/11.jpg)
Strategy
Secure anchor system, mooring points, vessels, boom control devices, etc.
Monitor & adjust as appropriate
Setup secondary system

Diversion Boom
Objective & Strategy Redirect spill from
one location to another or direct travel to a specific site for recovery
Sometimes confused with deflection
![Page 15: Strategies and Tactics for Boom Operations](https://reader036.fdocuments.net/reader036/viewer/2022062521/56816660550346895dd9e986/html5/thumbnails/15.jpg)
Diversion Boom

shoreline Recovery tactic Shore side or marine
recovery

Easier to handle Additional equipment
needed

Fast water Anchored middle
stream/river Allows boat traffic

Closed Chevron Configurations
Divides oil to two recovery areas
![Page 23: Strategies and Tactics for Boom Operations](https://reader036.fdocuments.net/reader036/viewer/2022062521/56816660550346895dd9e986/html5/thumbnails/23.jpg)

Don’t assume 100% efficiency Deploy back-up boom downstream Consider spotter/rescue person downstream Mark anchor points and trip lines Readjust angles as needed Continuous monitoring
Deployment Consideration and Limitations

![Page 26: Strategies and Tactics for Boom Operations](https://reader036.fdocuments.net/reader036/viewer/2022062521/56816660550346895dd9e986/html5/thumbnails/26.jpg)
Deflection Boom
Directs spilled oil away from a location to be protected or simply to change the course of the slick
Redirected away from an area but not recovered, in contrast with the term “diversion”, which is always associated with oil recovery.
