Strategies and tactics for boom operations

Strategies and Tactics for Boom Operations

Lt. Michael J. Magda

Western Wayne County HMRT, Livonia Fire & Rescue


Safety considerations

Safety Considerations

  • Weather

  • Response personnel

  • PPE

  • Vessel- size, crew & experience

  • Communication


Types of boom

Types of Boom

Sorbent Boom

Snare Boom

Fire Boom

Hard Boom


Boom components

Boom Components


Components of hard boom

Components of Hard Boom


Bridle components

Bridle Components


Boom classification

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

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

Boom Angles

  • Key consideration for deployment


Strategy

Strategy

  • Identify location & trajectory of spill

  • Identify, prioritize & select sensitive areas

  • Select configuration

  • Mobilize to location & deploy


Strategy1

Strategy

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

  • Monitor & adjust as appropriate

  • Setup secondary system


Booming tactics

Booming Tactics

Diversion

Deflection

Exclusion

Containment


Diversion boom

Diversion Boom


Diversion boom1

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 boom2

Diversion Boom

  • Tactic

  • .5 – 3.0 knots

  • Diverted to or from a shoreline

  • Recovery tactic

  • Shore side or marine recovery


Diversion c onfiguration

Diversion Configuration

Single boom- divert inshore or away from shore

Cascade- open or closed

Chevron- open or closed


Operating environments

Operating Environments

  • Commonly used

    • Protected water

    • Clam water

    • Fast water

  • Rarely used

    • Open water

  • Broken Ice

    • Difficult


Single boom divert deployment

Single Boom- Divert Deployment

  • Easily deployed

  • Minimal current

  • Anchored at site

  • Deployed at optimum angle


Divert offshore configurations

Divert Offshore Configurations

  • Single boom

  • Diverts away from shore

  • Recovered by

    • On-water recovery

    • Marine recovery systems


Cascade configurations

Cascade Configurations

  • Several booms

  • Allows vessel traffic

  • Easier to handle

  • Additional equipment needed


Open chevron configurations

Open Chevron Configurations

  • Fast water

  • Anchored middle stream/river

  • Allows boat traffic


Closed chevron configurations

Closed Chevron Configurations

  • Divides oil to two recovery areas


Closed chevron configurations1

Closed Chevron Configurations


Deployment consideration and limitations

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


Deflection boom1

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 boom2

Deflection Boom


Deflection boom3

Deflection Boom

  • Tactic

  • .5 – 3.0 knots

  • Diverts from a shoreline

  • Releasing it into the current again with a new trajectory


Operating environments1

Operating Environments

  • Commonly used

    • Protected water

    • Clam water

    • Fast water

  • Rarely used

    • Open water

  • Broken Ice

    • Difficult


Deflection configurations

Deflection Configurations

Fixed

Live

Cascade


Fixed deflection

Fixed Deflection

  • Fixed Deflection

    • Boom is anchored to the shoreline or bottom.


Live deflection

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

Cascade Deflection

  • Several booms

    • Fast current

    • Strong current

    • Shorter sections

    • Vessel traffic

  • Downside

    • Additional equipment


Exclusion boom

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 boom1

    • Protected water

    • Clam water

  • Rarely used

    • Open water

    • Fast water

  • Broken Ice

    • Difficult


Containment boom

Containment Boom

  • Objective & Strategy

    • Corral spilled oil on the water

  • Tactic

    • Fixed-boom tactic


Containment boom1
