Aquaculture Power

January 26th, 2009 by Andrew

Resolute Marine Energy, Inc. of Watertown, Mass. has an ocean energy harvesting system, which makes use of a buoy undulating on the ocean’s surface to create a pumping action with an arm to a platform below.

Ocean Farm Technologies, Inc. of Searsmont, Maine, has developed a 64-foot, 3,600-cubic-meter cage made of polyethylene and wire mesh to grow fish deep in the ocean.

As finfish aquaculture moves into deeper ocean sites, it will need sustained, autonomous sources of power. AquaPod net pens are designed to be moored at a stationary, licensed site at a depth near 100 feet. The power system creates compressed air that could power auto-feed systems, lower the cage, or in the future, power propellers to move the cage from place to place.

Contra Rotating Tidal Turbine for Aquaculture

October 31st, 2008 by Andrew

The Energy Systems Research Team at the University of Strathclyde is developing a contra-rotating marine current turbine with integral power take off. Using patented new rotor technology this design enables more energy to be delivered from the flowing stream while reducing mechanical complexity.

Compared to existing turbines of similar dimensions contra-rotating rotors are more efficient, yield a higher power output, and reduce the environmental impact associated with the downstream disturbance of the seabed and aquaculture.
Some of its features which might make it attractive for the aquaculture industry are its reduced environmental impacts, low maintenance and that there is no expensive piled seabed structure requirement.

Independent Power for Offshore Aquaculture

September 3rd, 2008 by Andrew

Increasingly, the ability to create large sustainable aquaculture production capability seems to be headed in the direction of automated systems.

Some proposals are going as far as autonomous aquaculture operations.

If this is the case then increasingly automated aquaculture operations will require more electrical power.

What are the sources of power that we could consider for autonomous offshore aquaculture operations? 

One way to think about power sources in the open ocean may be to consider the ability to derive power from ocean currents.  Perhaps the work conducted by SeaGen may be a signpost to the future?
