A number of different sizes of Boat Spray sets are available, ranging from large, permanently mounted equipment for use on tugs to small, portable inshore spray sets for use by small vessels. While ships can carry large loads of dispersant they are also much slower than aircrafts. This means that for a fast response it is important to identity potentially available vessels, with spraying systems permanently mounted to especially spray the type 3 dispersants (Neat). The portable spray sets will be suitable for oil platforms if restricted to Neat (Type 3) spraying. These systems can also be designed to spray both the dilute and neat dispersants thereby be suitable for harbor/terminal use.
