Strategies and Tactics for Boom Operations

Lt. Michael J. Magda

Western Wayne County HMRT, Livonia Fire & Rescue


Safety Considerations

  • Weather

  • Response personnel

  • PPE

  • Vessel- size, crew & experience

  • Communication


Types of Boom

Sorbent Boom

Snare Boom

Fire Boom

Hard Boom


Boom Components


Components of Hard Boom


Bridle Components


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


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


Boom Angles

  • Key consideration for deployment


Strategy

  • Identify location & trajectory of spill

  • Identify, prioritize & select sensitive areas

  • Select configuration

  • Mobilize to location & deploy


Strategy

  • Secure anchor system, mooring points, vessels, boom control devices, etc.

  • Monitor & adjust as appropriate

  • Setup secondary system


Booming Tactics

Diversion

Deflection

Exclusion

Containment


Diversion Boom


Diversion Boom

  • Objective & Strategy

    • Redirect spill from one location to another or direct travel to a specific site for recovery

    • Sometimes confused with deflection


Diversion Boom

  • Tactic

  • .5 – 3.0 knots

  • Diverted to or from a shoreline

  • Recovery tactic

  • Shore side or marine recovery


Diversion Configuration

Single boom- divert inshore or away from shore

Cascade- open or closed

Chevron- open or closed


Operating Environments

  • Commonly used

    • Protected water

    • Clam water

    • Fast water

  • Rarely used

    • Open water

  • Broken Ice

    • Difficult


Single Boom- Divert Deployment

  • Easily deployed

  • Minimal current

  • Anchored at site

  • Deployed at optimum angle


Divert Offshore Configurations

  • Single boom

  • Diverts away from shore

  • Recovered by

    • On-water recovery

    • Marine recovery systems


Cascade Configurations

  • Several booms

  • Allows vessel traffic

  • Easier to handle

  • Additional equipment needed


Open Chevron Configurations

  • Fast water

  • Anchored middle stream/river

  • Allows boat traffic


Closed Chevron Configurations

  • Divides oil to two recovery areas


Closed Chevron Configurations


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


Deflection Boom


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.


Deflection Boom


Deflection Boom

  • Tactic

  • .5 – 3.0 knots

  • Diverts from a shoreline

  • Releasing it into the current again with a new trajectory


Operating Environments

  • Commonly used

    • Protected water

    • Clam water

    • Fast water

  • Rarely used

    • Open water

  • Broken Ice

    • Difficult


Deflection Configurations

Fixed

Live

Cascade


Fixed Deflection

  • Fixed Deflection

    • Boom is anchored to the shoreline or bottom.


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.


Cascade Deflection

  • Several booms

    • Fast current

    • Strong current

    • Shorter sections

    • Vessel traffic

  • Downside

    • Additional equipment


Exclusion Boom

  • Objective & Strategy

    • Prohibit oil slicks from entering sensitive area

  • Tactic

    • Fixed-boom tactic

    • Completely boomed off

    • Conventional boom or tidal-seal boom


Exclusion Boom


Exclusion Boom


Operating Environments

  • Commonly used

    • Protected water

    • Clam water

  • Rarely used

    • Open water

    • Fast water

  • Broken Ice

    • Difficult


Containment Boom

  • Objective & Strategy

    • Corral spilled oil on the water

  • Tactic

    • Fixed-boom tactic


Containment Boom


Containment Boom


Operating Environments

  • Commonly used

    • Protected water

    • Clam water

  • Rarely used

    • Open water

  • Not recommended

    • Fast water

  • Broken Ice

    • Difficult
