VI. RECOMMENDED APPLICATION PROCEDURE
1. Application Method:
Aerial applied dispersant – spray from an aircraft flying with a controllable speed at altitudes of 30 to 50 feet. Spray nozzles should be sized to cover an area using 5 gallons per surface acre.
Spray from boat: NOKOMIS 3-AA can be applied by ships of workboat with spray booms mounted as far forward as possible. NOKOMIS 3-AA will generally be marketed in 55 gallon plastic drums. Application of the products may be made directly from the drum. By using a direct connection from pump to drum NOKOMIS 3-AA can be applied at full strength to the oil spill. The determination of whether to use NOKOMIS 3-AA at full strength or diluted with water must be determined by observations and evaluations made on-site at the oil spill.
Portable engine powered centrifugal water pumps are a satisfactory means of moving the dispersant from the container to the spill’s surface. Diesel-powered larger capacity pump may also be used. If the spill is confined to a small area, a hand-pump connected directly to the 55 gallon drum can be used. Hose diameters and lengths will relate to capacities required for the specific situation and distances from the pump to container and the spill. Fire hose has been successfully used, and with hand pumps small diameter hose is adequate. Fog nozzles on the dispersing end of the hose provide a fine spray of NOKOMIS 3-AA full strength or diluted as appropriate. Any type of hose nozzle can be used, but preferable one with the ability to produce a spray rather than a coarse stream.
2. Concentration/Application Rate:
NOKOMIS 3-AA may be applied to oil spills at full strength, or diluted with sea water. Where large areas of water may be covered with heavy concentrations of crude or Bunker C oil, it may be advantageous to apply NOKOMIS 3-AA at full strength. Where lighter fractions of petroleum are involved it is possible that dilutions of up to one part NOKOMIS 3-AA to 30 parts water may be applicable. Approximately 5 gallons of NOKOMIS 3-AA can be used for one surface acre of oil spill.
3. Conditions for Use:
Once NOKOMIS 3-AA is applied to the water’s surface, to obtain the most efficient emulsification of the oil it is necessary to agitate and mix dispersant, oil, and water thoroughly. In open unconfined areas, the use of ship propellers has been determined a practical way of accomplishing this purpose. By passing over the spill area on a grid system, the vessel’s propellers will churn the water, causing the needed mixing. For a large spill, two or more vessels may be needed to apply the product and agitate the water. In and around piers and similar confined areas it is necessary to apply the product from small boats, the shore, or pier itself. Where it is impossible or impractical to supply agitation with propellers of a vessel it is necessary to use pumps and a hose, applying salt water in the coarse stream and under sufficient pressure to cause surface turbulences and subsequent mixing.
