Description

Huon Aquaculture was looking for a solution to provide stand-alone power to their salmon fishing pods on the water of Macquarie Harbour in Tasmania. The power system needed to meet a number of key requirements.

Firstly, there were environmental considerations. The power generation couldn’t expose the Macquarie Harbour marine environment to diesel, coolants, or oil. It also needed to be low noise, as any sound would reverberate off the water and into the surrounding valley. Finally, it was essential that power was highly available, and the machinery was low maintenance.

Optimal worked in partnership with BOC to design and deliver a natural gas fuelled 65 kW microturbine, specially housed for marine environments. We installed a Capstone C65 Microturbine in a ten-foot container that features a custom-designed vane pack, or air inlet, to eliminate any seawater coming in. This is supported by an exhaust that has a custom-made silencer to reduce sound to less than 50dBA. The container is made for rapid connection of power, communications, and fuel delivery.

As well as designing and delivering the system, we also provided remote monitoring for a six-month period. The reliability test ran the turbine continuously for six months and met all performance KPIs.
