Commercial Diving


For over 17 years, Dive Works have been providing the Aquaculture Industry a specialised In-Situ Net Cleaning. We are experts in removing heavy growth from fish nets, sea cages, predator nets, and steel and aluminum structures, below the water on Atlantic Salmon Fish Farms. We provide a safe, economical and environmentally friendly in-water net cleaning system, in which individual units are capable of cleaning between 1500 – 3500m2 per day.

Clear Benefits

There are many benefits In-Situ Net Cleaning including; reducing the stress on the fish – during every net change fish stop feeding, thus reducing their overall weight. In-Situ Cleaning also reduces operating costs associated with net handling (as manpower, equipment, freight and drum washing etc.) and extends the life of the nets. All types of nets can be cleaned, whether its loose or tight nets, providing ultimate convenience – nets are washed under water by our self sufficient dive boat and crew with experienced and qualified divers.

Healthier Fish

It important to be proactive – timely removal of growth on nets ensures optimal environment for fish to grow. Ensuring optimal flow is maintained, which in turn increases oxygen flow through the nets is known to produce healthier stock. There are also less net changes that are required, which adds to the escape prevention measures by reducing fish changes. It also prevents predators such as jelly fish from entering the new nets which can lead to heavy fish losses.


Dive Works can conduct underwater inspections and repairs, using either a dive team for closer inshore regions or our ROVs for depths up to 300 metres. We offer inspection and repair of pipelines, mooring lines and subsea structures as well as cleaning and maintenance of underwater diffusers, pipelines and outfalls. We also offer water storage inspection, maintenance and cleaning, including reservoir cleaning using diver controlled vacuums to remove sediment waste and silt from reservoir floors. Reservoir inspections, both internal and external for asset management, future planning, OH&S and detection of leaks and sediment levels.


For subsea construction and maintenance projects, Dive Works provides specialised wet welding and Broco cutting services. While most diving contractors offer underwater welding and cutting services, very few are able to provide certifiable welds or the precision cutting that is often required.

At Dive Works our policy of employing tradesman diver’s means that only qualified metal fabricators and welders are used to carry out significant underwater welding and cutting projects.


Dive Works offers a complete suite of subsea construction, inspection and maintenance services tailored to suit Government and Water authorities, the Oil and Gas industry and the Aquaculture industry. Our services are designed to minimise downtime whilst ensuring that the value of the asset is prolonged and protected. Adhering to strict OH&S standards our highly trained team  provide a reliable and comprehensive service in all subsea environments.

Included in our services is the ability to use explosives, clear seabed’s, lay pipelines (either steel or polypipe) and lay concrete. We have delivered projects including construction of 600 metres of 515mm polypipe for discharge pipes. The total weight of the concrete blocks and pipes was in excess of 700 tonnes.
