Past Projects We Have Recently Completed

The Siabo - A New Pilot Boat headed to Papua New Guinea

We have worked closely with Norman Wright and Sons for quite some time now and it is always a pleasure to be involved in any of their projects.

This latest vessel, the "Siabo" is one of two pilot boats that will be patrolling the coastline of Papua New Guinea.

The engine room ventilation system was designed specifically for this project and incorporates a single grille as combined intake/outlet with dedicated internal ducts, fans and dampers to distribute and circulate the air correctly and efficiently. 

Operating in such extreme temperatures, it was essential that the Siabo has the best possible operating conditions to not only be economically viable, but to keep the crew safe.  There isn't too many places on earth hotter and more humid than Papua New Guinea and it was our pleasure to design and construct a system for a vessel that is going to help keep our northern neighbours safe. 

Feedback from the launch

We launched the pilot boat on Monday. First test run today. The feedback from the sea trial was that after coming back to the wharf the engine room is cooler than the wheelhouse!  Very impressive. Thanks for your efforts.

Port Of Brisbane - The BRISBANE

Marine Air Flow Ventilatio Project - Fast 8 Batam Ferry, Indonesia

We recently completed a project for Port of Brisbane which was the largest air intake grilles we have ever made. Manufactured for the BRISBANE a Trailing Suction Hopper Dredge this complete engine room ventilation system was a great project to be part of.

At 2100 mm plus, these grilles were manufactured in three sections to ensure the integrity of the grilles.

Brisbane River Cat

We are proud to have supplied the ventilation system for the about to be commissioned Brisbane River City Cat. 
  • You can see our new roof mounted fresh air ventilation modules designed for ferry passenger spaces where air conditioning is not desired.
  • You can also see our new Stainless Steel Drop Flap style Air Dampers- these allow personal access as well as function as an Air Damper.This saves space and expensive additional equipment purchases and installation- on a typical Ferry Cat this saves 4 expensive deck access hatches and installation costs.
  • And you can see our latest Intake Separator Grille Combination, with an inbuilt air duct mounting a pair of DC Compact Fans (producing approx 1400 l/sec) capable of supporting approx 700 Hp in a typical ferry.

We have worked hand in hand with Batam Fast Ferries in Indonesia on two projects to date, one a 41.6 meter ferry and the other their Ocean Raider fast ferry. Both projects were full ventilation systems designed by Marine Air Flow to support the General Arrangement supplied and were shipped from our factory here on the Gold Coast to their production facility in Indonesia.
