Project OVERVIEW
The Port Authority of New South Wales recently welcomed the Burra and Girawaa, two advanced firefighting vessels built by local company Birdon. These aluminium monohull vessels are designed to respond swiftly to major on-water incidents in Sydney Harbour and surrounding areas. Equipped with twin Scania engines and Namjet waterjets, they boast speeds exceeding 20 knots, essential for rapid response in emergencies.
Project GOALS
We wanted to create an effective ventilation and cooling system that utilized limited generator resources to allow that to remain free for critical applications.
Additionally, MAFI provided comprehensive fresh air ventilation for all void areas on the vessel, maintaining positive ventilation to mitigate condensation and prevent corrosion. This solution enhances operational reliability and longevity in critical vessel compartments.
The CHALLENGE
Weight was a major consideration in this project, so it was essential that our system was as light as possible while still allowing for the correct amount of airflow and temperature handling for a vessel that might not be moving for an extended period of time.
The SOLUTION
Due to the extensive equipment onboard utilizing the genset for power, we employed high-volume 24V DC fans. This strategic choice minimized additional load on the genset, allowing it to allocate more power to water pumps and other critical firefighting equipment. The fans operate efficiently on the 24V battery supply, crucial for fast-response vessels like firefighting boats.
These lightweight fans were custom-tuned to draw a maximum of 35 amps each, ensuring optimal power efficiency.
