Engine room ventilation system for Australian Border Force Vessel


In a refit managed by AST Oceanics Marine Air Flow are proud to have been engaged to rectify salt ingress issues the vessel was having.


The Thaiyak already managed their engine room cooling well so it was simply a matter of adding in Air Intake Grilles to reduce the salt spray and mist ingress the boat was having challenges with.


While many engine rooms do need a significant level of equipment, sometimes its an easy fix as was this one. We supplied engine room mist eliminator grilles to be installed which completely solved the vessel's challenges.

There was a whopping 25 air intake grilles installed in the Thaiyak! That is probably the most mist eliminators we've ever added to one vessel.


  • A total of 15 x Single stage intake separator grilles & 10 Two Stage Intake separator grilles.
  • These grilles service both the intake air and the outlet penetrations of the vessel.


Thaiyak Information

Manufactured in 2014 the Thaiyak was a joint effort from AST Oceanics, Strategic Marine and MMD which between them designed, managed and built this vessel for the Australian Border Force.


The Thaiyak was designed for long term deployment in remote marine environments so it is essential that the vessel engine room remains cool and dry.


At 9 years of age the engine room refit should enable this capable vessel to work for many more years servicing the Australian community.

build and launch of the Thaiyak.
