WIDESPRAY 

- Shipboard dispersant spray system

The WIDESPRAY dispersant spray system comprises of a diesel driven pump set, a pair of spray arms fitted 

with special nozzles and a set of hoses for the suction of seawater, dispersant and discharge to the spray 

arms.

The WIDESPRAY unit can be diesel or electrically driven.

 

The pump set is fitted with a flow meter and a recirculation valve that allows you to set the flow rate  

according to the desired application rate.

For dilute spraying an eductor is fitted which will give a mixture of up to 30% dispersant chemical in the 

seawater. This percentage can be varied. 

The standard 4-6 m spray arms can be fixed to the sides of a vessel, preferably near the bow. Each arm is 

supplied with 3-4 nozzles that provide an even spray pattern.

The nozzles are provided with down pipes for vessels with a high freeboard.
