MACS (Marine Aquaculture & Commercial Service) is at the forefront of the commercial and aquaculture industries in Australia.
The Victorian-based company has been involved in large scale operations including the Victorian Desalination Project and, more recently, the ongoing live harvesting of scallops in Port Philip Bay.
Founded in 2005 by two business partners, Peter Bold and Brendan Meloni, MACS has become a great Aussie success story.
Peter Bold is a successful Mussel farmer in Portarlington in Victoria.
Over the years he has gained an excellent operational knowledge of the Aquaculture industry and Port Phillip/Western Port Bays.
Brendan Meloni has been successful in business in the Commercial industry, and together the partners recognised that there was a need for a professional Commercial and Aquaculture Marine Service within their local area.
The partners developed a business plan and began building a new 13m boat, which they called the Beverly Anne.
In 2007 the Beverly Anne was launched and MACS quickly established a number of clients within the commercial market.
As MACS progressed, the Diving Services arm to the business was introduced.
Committed to safety and quality, MACS’ team of commercially certified divers specialise in a wide variety of offshore and inland services.
Part of the success in MACS’s diving operations has been the ability to produce Nitrox on-board the vessel, allowing divers to spend longer dive times under water, resulting in a higher production rate.
MACS was instrumental in being the first company to build this Nitrox producing machine in Australia.
MACS has also been successful in the implementation of Screw Anchors for the Commercial and Marine industry.
Screw anchors have been used throughout the world for many applications both on land and into the seabed.
Initially anchors that were installed into the seabed used a diver operated drill.
Having a diver bought with it some serious issues regarding OH&S, extra equipment on board, was time consuming and added an additional cost.
Therefore, the next development step was to remove the diving component, which in turn would result in a faster and most cost effective operation. All screw anchors are now installed totally driverless.
The screw anchor is designed to screw into almost any soft surface seabed. The screw anchor rig consists of a surface unit with a stand-alone diesel power unit running the pneumatics and hydraulics.
The machine is connected to the subsurface drill unit via a 50m umbilical.
This unit is controlled by the operator using an underwater camera and has a fine degree of control, allowing gentle and correct placement of the drill unit, minimising any potential environmental damage. The rigging doesn't contact the seabed as it goes straight up towards the surface where it is attached to a buoy.
Screw anchors are positioned using a DGPS, which results in precise positioning of each application.
Underwater video backup is also used to verify correct installation. Screw anchors also have a superior holding ability in comparison to concrete weights and have a less warp ratio. With a steeper angle on the warp there is no contact with the seabed.
The environmental impact of the screw anchor is negligible, and many have been installed throughout Australia where any other type of anchor would not have been allowed. The major environmental advantage of the anchor is the avoidance of “chain-drag” on the seafloor there for reducing seagrass erosion. After installation the only visible evidence of the screw anchor on the seafloor is a small "footprint" and the anchor warp.
MACS has ambitious plans to keep growing its business nationally and internationally, with a continued focus on outstanding customer service.
