Preventions● Double-hulling-build double hulls into vessels,which reduces the
risk and severity of a spill in case of a collision or grounding. Existing single-hull vessel can also be rebuilt to have a double hull.
● Secondary containment-methods to prevent releases of oil or hydrocarbons into environment.
● Blowout preventer.
● Well castings.
Conclusion● Most oil spills and most serious accidents
are caused human error, so this can be redused if one takes extreme precautions and proper safety assessments.
● Focusing on many techniques such as blowout preventer and well casting can contain the oil spill.
