OSD/LT - Oil Spill Dispersant
Description
OSD/LT oil spill dispersant is a superior low toxicity oil dispersant for combating oil spill pollution. Powerful wetting agents and solvents combine with a fast penetrating, oil-soluble liquid carrier specifically designed to disperse oil spilled on water.
OSD/LT oil spill dispersant also has proven itself to be an effective product for cleaning and dispersing oil on solid surfaces such as docks, decks and piers.

Application and Use
Through extensive testing and research, Drew Marine has developed OSD/LT dispersant, a highly effective, low toxicity oil spill treatment, to meet today’s stringent pollution and environmental standards. OSD/LT dispersant has been granted license by the following agencies:
• U.K. DEPARTMENT FOR ENVIRONMENTAL, FOOD & RURAL AFFAIRS (DEFRA)
• SCOTTISH OFFICE AGRICULTURE, ENVIRONMENT AND FISHERIES DEPARTMENT
as a Type 1 Dispersant
In addition, OSD/LT dispersant is approved by the following governments:
• AUSTRALIA • JAPAN
• PHILIPPINES • HONG KONG
• SINGAPORE When approved and used as directed, the application of OSD/ LT dispersant as soon as possible after an oil spill occurs will enable the dispersant to effectively diminish overall damage to the environment.
I. Spills on Water
A. For Small Spills: Spray Method
1. Spray the predetermined amount of full strength OSD/LT oil spill dispersant uniformly over the surface of floating oil using a pressurized spray device with a coarse spray pattern.
2. Allow about 15 minutes for OSD/LT dispersant to penetrate, then vigorously agitate the treated surface. This may be accomplished by one of the following methods:
(a) Delivering a jet of water onto the treated oil from a fire hose.
(b) Backing a lightly loaded launch through a treated slick.
(c) Allowing a 3-5% OSD/LT dispersant in seawater solution spray to strike the oil ahead of the vessel’s bow wave, thereby obtaining agitation from the bow wave as well as from the screws.
(d) Towing a five-bar gate or modified five-bar gate as specified by Warren Spring Laboratory through the treated slick at 2-4 meters/second. B. For Larger Spills: Positive Displacement - Pump or
Eductor Method
1. Spray a solution of 3-5% OSD/LTTM oil spill dispersant on floating oil by pumping seawater through a boom or spray device while a positive displacement pump of eductor injects full strength OSD/LT dispersant into the water pump suction at a rate previously determined necessary to treat the spill.
2. This should be done from a height of approximately 75cm (30 inches) above the surface of the slick in front of the normal bow wake to agitate the treated oil and allow time for penetration.
3. Additional agitation can be provided as described in A.1. on the previous page.
II. Spills on Solid Surfaces (Docks, Decks, Piers, etc.)
A. Pour full strength OSD/LT dispersant on the oil spill and mix thoroughly with a mop, broom or other appropriate agitating device.
B. Apply water and continue the agitation until penetration is complete.
C. Remove the treated oil/water mixture by flushing with full force stream of water.
III. Accumulations on Dock Pilings, Harbor
Structures and Supports
A. Spray contaminated areas with concentrated OSD/ LT dispersant and allow to soak for 15-30 minutes.
B. Scrub treated surface with a stiff brush.
C. Rinse t scrubbed area with a full force stream of water.
D. Repeat Steps A through C as often as necessary to clean the contaminated surface.
IV. Oil on Beaches and Shore Line
When approved and used as directed, the application of OSD/LT dispersant as soon as possible after an oil spill occurs will enable the dispersant to effectively diminish the overall damage to the environment. On thin layers of oil, 1 liter of OSD/LT dispersant will disperse 25 square meters of oil.
NOTE: It is advised that a vessel in an oil spill should not use its evaporators during cleaning operations. This will avoid possible contamination of evaporators by treated oily seawater which might be drawn into the suction lines. Where there are specific laws regarding the application of oil spill treatment chemicals, it is necessary to consult with the local regulatory agency before application of any oil spill dispersant product.
