MODULE 6 Containment and Protection Familiarize with the structure, uses, deployment techniques and limitations of boom Session Outcomes Areas of Knowledge: Main response strategies and their basic advantages and disadvantages Application and limitations of various boom types Boom deployment techniques: equipment, vessel And ancillary equipment selection Generic boom components and design Containment & Response Strategies Protection Dispersant Application Monitor Only Shoreline Protection Shoreline Clean-up In-situ Burning Every spill is different; these response strategies may or may not be used Containment & Protection Protect Shoreline/Near Shore Sensitivities Deflect to Enhanced Collection Areas Contain & collect for recovery Assist Shoreline Cleanup There are various types of boom Types of Boom Benefits / Disadvantages Shore Sealing Boom Full Tidal Range Set boom before filling Poor sealing on rocks current velocity (knots) 0.75 knots 6 Location 5 current Access 4 boom angle 3 2 1 Success 0 10 20 30 40 50 60 70 80 90 100 boom angle (degrees) Deflect Protect Inshore Booming Contain Assist with Shoreline Clean-up Associated Ancillaries Preserving sensitive areas Deflecting to enhanced collection points Protect Prior to impact Protection of specific areas Limiting environmental impact Reduce area of Stranding Contain Collect and control for recovery. Corral to maximise efficiency of recovery equipment. Assist with Shoreline Clean-up Reduce impact area of re-mobilised oil Corral re-mobilised oil to recovery equipment Air Blowers Water Pump & Hoses Towing Connectors Ancillaries Anchors Anchor Chains Buoys Spares Deployment Technique Land Land Beach Beach Current Current Opt to take out boom in sections Sea Sea Deployment Technique Land Beach Boom Towing Current Sea Stakes Anchors Shore Sealing Boom Secure Points Anchoring River Booming Fast Flowing Rivers Angle of booms Large deflection booms & small collection points Multiple collection points For collection and recovery In-situ burning Offshore Booming Protection of deep water inlets/fish farms Ocean Booming Formations U configuration V configuration J configuration Single ship system Large entrapment area Good wave following properties Will work with deflated sections Pros & Cons Boom speed limitations Only 10%-20% recovery of oil at sea depending on type of release Weather dependant Offshore Ancillaries Vessels of opportunity Good communication Good low speed manoeuvrability Current Speed Limitations Splash over Drainage Man power Logistic support New Equipment Trends Move away from large, heavy systems. Compact, lighter, easier to handle systems preferred. Lower encounter / recovery rates but multiple units. Main response strategies and their basic advantages and disadvantages Session Review Application and limitations of various boom types Boom deployment techniques: Equipment, vessel And ancillary equipment selection Generic boom components and design
