Oxygen systems

Oxygen where it counts.
Delivered when it matters.

Dissolved oxygen is the defining variable of any farm. When it holds, everything behind it follows: appetite, growth, feed conversion, fish health. When it slips, every hour counts.

We engineer oxygen systems around that reality. From supply and storage to diffusion and monitoring, every system is designed for working water: variable loads, changing seasons, and the demand for redundancy that performs on its worst day, not its best.

Through collaborations with leading oxygen and subsea infrastructure providers, we deliver complete oxygen solutions with guarantees on performance, reliability and long term value.

Supply & storage
Bulk and on demand oxygen supply, engineered for continuous delivery across your site infrastructure.
Diffusion & aeration
Engineered diffusion that moves oxygen where it does the most work, efficiently and quietly.
Redundancy & backup
Backup supply and automatic changeover engineered in, so a single fault never becomes a stock event.
Monitoring & control
Continuous dissolved oxygen monitoring with automated control, alarms and escalation.

Air systems

Air under pressure.
Held exactly where it works.

Compressed air is the quiet workhorse of a marine site. It drives the bubble curtain, feeds the diffuser line, holds the water column moving and keeps treatment systems doing their job. It is only ever noticed when it stops.

Advanced Air builds the packages in house. Compressor skids engineered for marine service, housed in weatherproof acoustic enclosures, configured around the pressure, volume and duty cycle your operation actually needs.

From a single skid on a barge to a site wide network feeding several curtain lines, the whole path is designed together: generation, distribution, diffuser and control. The air arrives where it does the most work, at the rate it is needed, with the redundancy to hold when conditions turn.

Compressor packages
In house Advanced Air compressor skids, specified and built around your pressure, volume and duty cycle.
Acoustic enclosures
Weatherproof, sound attenuated housings built for deck, barge and shoreline installation, with safe access for service.
Diffuser & curtain lines
Subsea diffuser hose, manifolds and curtain lines engineered to deliver air evenly along the full length of the run.
Control & support
Automated control and monitoring, with ongoing service across Australia and New Zealand.

Power systems

Power that holds.
From first start to last watch.

On the water, power is not a convenience. It is the system every other system depends on: pumps, feeding, monitoring, lighting, comms, life support. When generation holds, the operation holds.

Advanced Power generating sets are engineered for marine service, then configured around the requirements of your operation. Output, redundancy, footprint, control and the way your crew actually work: the design starts with your vessel or site, not a catalogue.

From single sets to matched installations, every package is delivered with the control and instrumentation to run it with confidence, and backed by the same people who installed it.

Marine generating sets
Generating sets specified and built around the electrical and operational demands of your vessel or site.
Control & instrumentation
Control panels, metering, alarms and shutdown protection that put the state of your power system in front of the crew.
Installation & commissioning
Supply, installation and commissioning managed on site, delivered ready for service.
Service & support
Ongoing maintenance, troubleshooting and parts support across Australia and New Zealand.
