Study Notes

Containment & Protection Strategies

Spill response strategies include containment and protection, dispersant application, monitor only, shoreline protection, shoreline clean-up and in-situ burning
Each spill is unique and the chosen response strategies may vary
Boom containment is a primary containment and protection strategy
Boom containment protects shore/near shore sensitivities
Boom containment deflects oil to collection areas
Boom containment assists with shoreline clean-up
Boom containment is used to corral and collect oil for recovery

Boom Types

There are various boom types to choose from, each with its benefits and disadvantages
Shore sealing boom is designed for a full tidal range
Shore sealing boom should be set before the area is filled
Shore sealing boom does not perform well on rocky surfaces.

Inshore Booming

Booming is effective in diverting oil, protecting sensitive areas, assisting with shoreline clean-up and containing oil
Boom angle, current velocity and boom location all impact the success of boom deployment
Inshore booming requires ancillary equipment such as air blowers, water pumps and hoses, towing connectors, anchors, anchor chains, buoys and spares

Boom Deployment Techniques

Booming deployment should occur in sections
Booming deployment should be done in a seaward direction
Deployment of boom in sections reduces the overall stress on the system
Anchor boom to the shore using stakes or anchors

Booming Deployment Techniques

Booming should be towed in a direction opposite the direction of the current
River booming should be used with an angle of booms to account for fast moving currents
Large deflection booms and small collection points are recommended for faster currents
Multiple collection points may be necessary on rivers with fast currents

Offshore Booming

Offshore booming is used for oil collection and recovery, in-situ burning, protection of deepwater inlets and fish farms
Common offshore boom configurations are U, V and J shapes
Single ship systems are another offshore booming option.

Offshore Booming Advantages & Disadvantages

Offshore boom configurations have a large entrapment area
Offshore boom configurations perform effectively in wave conditions
Offshore boom configurations can be used with deflated sections
Offshore boom configurations are limited in boom speed and only recover 10%-20% of oil at sea
Offshore booming success is weather dependent

Offshore Booming Ancillaries

Offshore booming utilizes vessels of opportunity with good communication and low speed manoeuvrability capabilities

Boom Limitations

Current speed, splash over, drainage and manpower are factors that impact boom effectiveness
Logistical support is a fundamental requirement for successful boom deployment

New Equipment Trends

The trend in boom deployment is to move away from large, heavy systems.
