Practical Experience of Dispersant Usage

Source

This paper examines selected aspects of dispersant usage from a practical point of view and with reference to the experience gained from oil spill incidents around the world.

The factors to be considered when deciding what, if any, response should be employed in the event of an oil spillage are discussed and the importance of well-prepared contingency plans stressed.

Environmental considerations are of obvious importance in deciding whether or not dispersants should be used, but it is explained that ultimately the decision will depend upon the priorities for protection and the unique circumstances of each incident. It is emphasized that the effective use of dispersants from vessels and aircraft depends upon good initial evaluation of the response required and continual control of the whole operation. Aerial surveillance is essential to continually reevaluate and direct the response in an ever-changing situation.

It is concluded that dispersants, applied correctly and after detailed consideration of the particular circumstances of the incident, have a role to play in combatting oil spillage at sea and can prevent or reduce damage to coastal resources and amenities. They should be regarded, however, only as one of the many courses of action open to cleanup controllers and not as a panacea for all ills.
