Engine Room Ventilation for Line Handling Vessel
Marine Air Flow has been proud to work in conjunction with Dongara Marine & Southerly Designs for a few years now. This latest project we have supplied engine room equipment for was recently launched by Dongara Marine and we think you will agree it's a beast of a boat!
Specifically built for Jetwave Marine, who provides offshore service vessels catering to primarily the oil, gas and resource industries Australia wide, this is the second in the series that Dongara Marine has manufactured. A sister to the Stanley Point, the Nelson Point which was also designed by Southerly Marine as a line handling boat, is 9.7 meters in length and powered by a single Yanmar 365hp motor. That's 272kw.
Marine Air Flow's Involvement:
Our supplied equipment for the Nelson Point included:
- Intake single stage separator grilles with coalescing fabric particulate filters.
- Outlet mist eliminator grilles also with particulate filters.
- Stainless steel air dampers (fire flaps if you use old school terminology) &
- 24volt DC compact fans for supply and extraction air.
Knowing this vessel will be operating in Port Hedland in the very hot far north of WA, it is essential that the engine room and all its components are kept cool and operational at all times. As you can see in the video below, conditions could get much worse that this and it is extemely important to ensure that salt mist, spray and water are kept out of the engine room without affecting the operating temperature.
Specific calculations are made for all our engine room ventilation projects and to ensure that this 365hp Yanmar motor had the best possible operating air conditions, our calculations take into account:
- the litres per second for engine combustion air,
- an added calculation to ensure that the engine room air volume exchanges at 120 time per hour as it should &
- also takes into consideration the size of the engine room.
We have been very proud to have been associated with both Dongara Marine and Southerly Designs especially as Brad, our director is actually from that area of Western Australia. It's always great to see local companies doing so well.
