  1. Strategies and Tactics for Boom Operations Lt. Michael J. Magda Western Wayne County HMRT, Livonia Fire & Rescue

  2. Safety Considerations • Weather • Response personnel • PPE • Vessel- size, crew & experience • Communication

  3. Types of Boom Sorbent Boom Snare Boom Fire Boom Hard Boom

  4. Boom Components

  5. Components of Hard Boom

  6. Bridle Components

  7. Boom Classification Clam water boom (harbor boom)  1’ Fast water boom (clam water/fast current boom)  1’ Protected water boom  3’ Open water boom (ocean boom)  6’ Tidal-seal boom

  8. 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

  9. Boom Angles • Key consideration for deployment

  10. Strategy • Identify location & trajectory of spill • Identify, prioritize & select sensitive areas • Select configuration • Mobilize to location & deploy

  11. Strategy • Secure anchor system, mooring points, vessels, boom control devices, etc. • Monitor & adjust as appropriate • Setup secondary system

  12. Booming Tactics Diversion Deflection Exclusion Containment

  13. Diversion Boom

  14. Diversion Boom • Objective & Strategy • Redirect spill from one location to another or direct travel to a specific site for recovery • Sometimes confused with deflection

  15. Diversion Boom • Tactic • .5 – 3.0 knots • Diverted to or from a shoreline • Recovery tactic • Shore side or marine recovery

  16. Diversion Configuration Single boom- divert inshore or away from shore Cascade- open or closed Chevron- open or closed

  17. Operating Environments • Commonly used • Protected water • Clam water • Fast water • Rarely used • Open water • Broken Ice • Difficult

  18. Single Boom- Divert Deployment • Easily deployed • Minimal current • Anchored at site • Deployed at optimum angle

  19. Divert Offshore Configurations • Single boom • Diverts away from shore • Recovered by • On-water recovery • Marine recovery systems

  20. Cascade Configurations • Several booms • Allows vessel traffic • Easier to handle • Additional equipment needed

  21. Open Chevron Configurations • Fast water • Anchored middle stream/river • Allows boat traffic

  22. Closed Chevron Configurations • Divides oil to two recovery areas

  23. Closed Chevron Configurations

  24. Deployment Consideration and Limitations 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

  25. Deflection Boom

  26. 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.

  27. Deflection Boom

  28. Deflection Boom • Tactic • .5 – 3.0 knots • Diverts from a shoreline • Releasing it into the current again with a new trajectory

  29. Operating Environments • Commonly used • Protected water • Clam water • Fast water • Rarely used • Open water • Broken Ice • Difficult

  30. Deflection Configurations Fixed Live Cascade

  31. Fixed Deflection • Fixed Deflection • Boom is anchored to the shoreline or bottom.

  32. Live Deflection • Live Deflection • Attached to vessels and held in position by the power of the vessels • One end anchored and the other end held in position with a vessel.

  33. Cascade Deflection • Several booms • Fast current • Strong current • Shorter sections • Vessel traffic • Downside • Additional equipment

  34. Exclusion Boom • Objective & Strategy • Prohibit oil slicks from entering sensitive area • Tactic • Fixed-boom tactic • Completely boomed off • Conventional boom or tidal-seal boom

  35. Exclusion Boom

  36. Exclusion Boom

  37. Operating Environments • Commonly used • Protected water • Clam water • Rarely used • Open water • Fast water • Broken Ice • Difficult

  38. Containment Boom • Objective & Strategy • Corral spilled oil on the water • Tactic • Fixed-boom tactic

  39. Containment Boom

  40. Containment Boom

  41. Operating Environments • Commonly used • Protected water • Clam water • Rarely used • Open water • Not recommended • Fast water • Broken Ice • Difficult
