Study Notes
Oil Spill Cleanup Methods
- Oil spill cleanup uses various methods, like tools for home repairs.
- Key offshore methods include skimming, in-situ burning, and chemical dispersants.
Skimming
- Removes oil from the water surface, preventing coastal impact.
- Equipment: Various types (e.g., disks, drums) collect oil.
- Collected oil is transferred to collection tanks.
- Optimal conditions: Calm seas, daylight, thick oil slick.
- Challenges: "Encounter rate" (direct contact needed); often collects oil-water mixture.
In-Situ Burning
- Burns oil directly on the water surface to reduce volume.
- Method: Fire-retardant boom concentrates oil for burning.
- Optimal conditions: Mild winds, calm seas, daylight, thick oil layer.
- Environmental considerations: Crucial air monitoring (smoke and residue effects).
Chemical Dispersants
- Sprays onto oil slick to break down oil into smaller droplets.
- Benefits: Smaller droplets allow quicker microbial breakdown.
- Environmental considerations: Potential harm to marine life (water column and seafloor); careful use.
- Optimal conditions: Daylight, mild winds, moderate seas, away from shore/shallow water.
- Natural dispersion: Waves can naturally break oil; dispersants speed up this process.
Ideal Conditions Summary
- Skimming: Calm seas, daylight, thick oil.
- In-Situ Burning: Mild winds, calm seas, daylight, sufficient oil thickness.
- Chemical Dispersants: Daylight, mild winds, moderate seas, away from sensitive areas.
