Wave energy developer Minesto creates new simulation software

Wave energy technology group Minesto has developed a new simulator to aid the development of its "Deep Green" marine power plant, the Swedish company has announced.

The simulator, developed in-house by Minesto's research and development department, is based on two existing open-source programs designed for commercial flight simulation and marine vehicle simulation.

Minesto calls the tool HAMoS (Hydrodynamic Analysis and Motion Simulation) and said it is "believed to be the first in the world to simulate the movements of a flying tethered underwater vehicle."

The company describes its Deep Green wave energy devices as an "underwater kite, comprised of a wing and a turbine which is secured to the seabed with a tether", making HAMoS a valuable tool in determining how the units will operate in an undersea environment.

"We can easily scale and change different variables in the simulator to predict and optimize Deep Green’s power production performance with great accuracy," CEO Anders Jansson said. "It is of great commercial value to be able to estimate the cost of energy more precisely at a specific location."

By combining the flight and marine vehicle simulation programs, Minesto said its new program will be able to calculate lift, drag and added mass acting on Deep Green bodies. Information gathered can then be used to modify the unit's shape, flight path and control system.

The company said HAMoS could also eventually be used as a training tool once Deep Green units begin commercial operation.

HydroWorld.com reported in November 2012 that Minesto was beginning quarter-scale testing of its Deep Green units in Northern Ireland's Stangford Lough.

The company was also recently recognized as one of Sweden's hottest young technology companies in being named to the "33 List" compiled by technology magazine Ny Teknik and business publication Affarsvarlden.
