Tropical Environment Patrol Boat System

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.

The Siabo system ready for despatch. 


A compact designed system, this was designed with a single mist eliminator grille as a combined intake and outlet with our compact fans for ventilation and air dampers for fire safety. As you can see from the pics below, the Siabo is a compact vessel, however it is still important to ensure correct air flow in a tight space.

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.
