Spray Arms

Designed for installation on offshore and inshore oil spill response vessels, Spray Arms can be used for both neat and dilute oil dispersant application.

Ayles Fernie supply standard Spray Arms from 3m to 10m in length. Assembled on deck and mounted to the port and starboard sides of the vessel utilising the gunwale or handrail, when not in use they can be removed and stowed.

Retractable Spray Arms are mounted on cantilever support beams that extend from the port and starboard sides of the vessel and are lowered into position.

Spray Arms are supplied with downpipes to ensure that the nozzles are positioned at the optimum 1m to 2m height from the water surface.

The type and number of nozzles is varied depending on the length of the Spray Arms to ensure an even distribution of neat or dilute dispersant.

Compatible with BOATSPRAY and CLEARSPRAY oil dispersant spray systems manufactured by Ayles Fernie.
