ICS 209 Exercise

Incident

An offshore platform crew, watching 4 seasons of a popular cable TV show rather than their gages, cause a three-day leak of 15 bbl/hr of a light Louisiana crude

Wind is 10 knots the first day, strengthens to 20 knots for the next two days and then returns to 10 knots, always from the north.

Water temp is 68 F under open ocean conditions.

Limited skimming equipment is employed and recovers 5/bbl hour for eight hours during the first day.

On the second day, dispersants are proposed on 20% of the surface slick with an estimated efficiency of 40%.

The on-scene command wants an ICS 209 form prepared for day 2 of the spill.

Use WebGNOME’s Fate Mode to provide the data for the ICS 209 form.

  7. Repeat the procedure above, but changing the speed to 20 for the next two days (4 records), then back to 10

  8. Click Save

Response Options:

Limited skimming equipment is employed and recovers 5/bbl hour for eight hours during the first day.

On the second day, dispersants are proposed on 20% of the surface slick with an estimated efficiency of 40%.

Skimming

  1. Click “Response Options”

  2. Click “ADIOS Skimming”

  3. Optionally set a name for this skimmer

  4. Leave the “Time of Skim” at the model start time

Run the model

Click “Solve”

The on-scene command wants an ICS 209 form prepared for day 2 of the spill.

  1. When the model is done running, click the “ICS209” tab.

  2. Set the operational period by clicking and dragging on the the oil budget graph.

    or

  3. Set the Start time and End Time of the Operational Period Directly

The resulting Table should have everything you need for the ICS 209 form.
