Efficient Wave-Generated Power … Really!
Wave-generated power could be considered the Rodney Dangerfield of offshore renewable energy sources; it gets no respect. There have been a number of high-profile, expensive failures that have conspired to give the sector a poor reputation despite a number of engineering advances. A new entrant is SurfWEC offering a patented “surf-making” Wave Energy Converter which has been in development since 2007. Its developers promise it will stand out from the field and perform where others have failed. How?
The Future: Autonomous Robotic Hull Grooming
Ship hull biofouling has significant impacts on fleet readiness, ship performance, cost, and the environment. Biofouling results in increased hydrodynamic drag which results in greater fuel use and greater emissions per distance traveled than a hydraulically-smooth hull. A study by Schultz, et al. found the typical fouling rating (FR) of a US Navy DDG-51 class vessel, FR-30, increases fuel consumption by 10.3% over a hydraulically-smooth DDG-51. Results showed that reducing this…

Predicting the Motion of the Ocean
For thousands of years sailors have looked out to sea, anticipating the motion of their craft from the waves they see coming. The nature of this constant motion, phasing in and out with the groups of waves, influences the safety of operations, from moving about the deck or rigging to transferring people and materials between craft. Waves and the resulting motions are a key factor in deciding whether to perform an operation. Could you do better than your eyeball for predicting when that next big wave is going to knock you off your feet? When the U.S.

Fighting Barnacle Buildup with Biology
New research solves a mystery behind the gunk that sticks to the bottoms of ships. The coating of barnacles and other growth along the bottoms of vessels is more than just an eyesore. Biofouling, as it is known, slows down ships and impedes the readiness of emergency response and military vessels. “Biofouling is an economic issue,” said San Diego State University biologist Nick Shikuma. A new study by Shikuma identifies key developmental steps these waterborne organisms must take to metamorphose from their larval to adult state.
Will Naval Operations Heat up in the Arctic?
As diminishing sea ice in the Arctic Ocean expands navigable waters, scientists sponsored by the Office of Naval Research have traveled to the region to study the changing environment and provide new tools to help the U.S. Navy operate in a once-inaccessible area. "This changing environment is opening the Arctic for expanded maritime and naval activity," said Rear Adm. Mat Winter, chief of naval research.
