Appendix 1 Operational Tactics

1. 1. Open Water Conditions

1.1.1 – In Situ Burning (ISB)

Equipment Function Number of Staff Mobilization Time Deploy Time Tug 1 Tow boom 2

Tug 2 Tow boom 2 Fire Boom Containment, ISB 2‐3

1.1.1.1 - Description

In situ burning is a technique to remove oil from the surface of the water before it reaches the ice or shoreline. Vessels must capture the oil and tow it to a safe location (defined by the FOSC with respect to water depth, smoke plume, distance from population and other responders) while moving at less than 1 knot. This tactic is enhanced if the wind is blowing away from populated areas and if the collected oil forms a thick enough layer (>2-3 mm) so it will burn better.

1.1.1.2 - Objective of this Demonstration

To evaluate the ability for local vessels to handle and manipulate fire boom in a safe and efficient manner.

1.1.1.3 – Measure

• Keep the surrogate (oranges) inside the boom

• Correlate with GPS positioning data

• Handling and support adequate

1.1.2 – Herding

Tug 1 or 2 Working platform 2

Fire monitor Herd surrogates 2

1.1.2.1 - Description

Herding is designed to move the oil slick into an area where it can be burned, contained or recovered. It is usually done with a fire monitor mounted on the bow of the vessel that can move oil from a fixed location into a preferred area. In the open water, it is useful in gathering up wayward slicks into one mass for an easy recovery operation.

1.1.2.2 - Objective of this Demonstration

To evaluate the ability for local vessels to handle a fire monitor and understand available strategies in corralling oil.

1.1.2.3 – Measure

• Able to swivel around on tug deck

• Move surrogates into desired location

• Handling and support adequate

1.1.3 – Finding Collection Points

1.1.3.1 - Description

During most time of the year, oil will gather in natural collection points along the shoreline in locations where the current and waves are minimal. In ice conditions, oil will also move to these types of areas. Using the ice as a natural barrier for containment is crucial for recovery without pushing the oil below or on top of the ice.

1.1.3.2 - Objective of this Demonstration

To evaluate the ability for local vessels to approach and collect oil without disturbance. Evaluate the use of herding to move oil into collection areas.

1.1.3.3 – Measure

• Vessel can stand-off the location without contacting the ice

• Vessel can stabilize location while skimmer is deployed.

1.1.4 – Remotely Operated Vehicle (ROV)

ROV Detect surrogate 3

1.1.4.1 - Description

The ROV is used to provide visuals of the oil under ice that cannot be seen by the human eye. It can be deployed in the water and powered by thrusters and is able to stay underwater for hours with sensors and cameras to provide all necessary oil spill information to the responders. It can also be used down a hole if the ice is solid and personnel are deployed.

1.1.4.2 - Objective of this Demonstration

To evaluate the ability for local vessels to handle and manipulate an ROV without disturbing the oil or ice. Determine if cameras are adequate for this task or if other sensors are needed.

1.1.4.3 – Measure

• Able to detect surrogates under water

• Able to deploy equipment

• Ease of control

• Avoid damage to ROV by hitting ice

• Quick data feedback

• Able to deploy under-ice recovery techniques

2.1. Broken Ice Conditions

2.1.1 – ISB

Tug 1 Tow boom 2

Tug 2 Tow boom 2 Fire Boom Containment, ISB 2‐3

2.1.1.1 - Description

In situ burning is a technique to remove oil from the surface of the water before it reaches the ice or shoreline. Vessels must capture the oil and tow it to a safe location (defined by the FOSC with respect to water depth, smoke plume, distance from population and other responders) while moving at less than 1 knot. Broken or brash ice may be collected along with the oil but vessels do their best to avoid amassing a large number of ice pieces. This tactic is enhanced if the wind is blowing away from populated areas and if the collected oil forms a thick enough layer that would burn better.

In areas where the broken ice is large and tightly packed, ISB is employed by using the ice as a natural barrier against which the oil concentrates.

2.1.1.2 - Objective of this Demonstration

To evaluate the ability for local vessels to avoid as much broken ice and handle the fire boom in a safe and efficient manner.

2.1.1.3 – Measure

• Keep the surrogate (oranges) inside boom

• Collect the least amount of broken pieces of ice

• Correlate with GPS positioning data

• Demonstrate on-board temporary storage

AUV Detect surrogate 3

3.1.1 - Description

The AUV is used to provide detection of the oil under ice that cannot be seen by the human eye.

It can be deployed in the water and powered by thrusters and is able to stay deployed for hours with sensors and cameras to provide all necessary oil spill information to the responders. It can also be used down a hole if the ice is solid and personnel are deployed.

3.1.2 - Objective of this Demonstration

To evaluate the ability for local vessels to handle an AUV without disturbing the oil or ice.

Determine if cameras are adequate for this task or if other sensors are needed.

3.1.3 – Measure

• Able to detect surrogates under water

• Able to deploy equipment

• Avoid damage to ROV by hitting ice

• Quick data feedback

• Able to deploy under-ice recovery techniques
