Wave energy converter (WEC) systems have not yet made it to the stage of development of wind and solar systems, but wave energy is a concentrated form of wind energy covering over 70% of the Earth and presents a fascinating opportunity for the future of renewable energy. 

Martin & Ottaway is developing a novel approach to commercially harvest wave energy called SurfWEC. Ocean wave energy conversion involves the simple relationship between mass and velocity. The more water mass a WEC displaces per second, the more power it puts into the energy storage and conversion subsystems. The term “marine hydrokinetic” is often used to describe these systems and abbreviated “MHK” systems. Three types of MHK systems convert power from either surface wave, tidal, or ocean current motions to useful forms of power or energy such as electricity or charged batteries or pressurized fluids respectively. The SurfWEC system converts the power from ocean surface waves into grid quality electricity. 

The SurfWEC system incorporates an energy storage subsystem in each unit capable of storing over 500 kilowatt-hours (500 kWh) of energy. In some scenarios, energy storage is commercially important as it allows SurfWEC operators to sell both electric power and electric power capacity.

 A truly powerful wave farm is analogous to positioning a swath of 200 SurfWEC units over an area of 12 miles (North to South) by 2 miles (East to West) and 20 to 200 miles offshore from New Jersey. A SurfWEC farm of this size would have over 1000 Megawatts (1000 MW) of nameplate capacity.

While the primary design function is industrial scale electricity production, harnessing wave energy reduces wave energy behind the wave farm; therefore, wave impacts behind the wave farm are reduced, which is something to consider for offshore wind farm and shoreline protection applications. 

The SurfWEC system is differentiated from other existing WEC system with the ability to autonomously generate surfing wave conditions in deep water locations offshore. Without this ability, it is not possible to harness the surge potential in offshore waves. By having the ability to convert seas and swell into surge offshore, the SurfWEC is capable of being built out into economically competitive, industrial scale, electricity production projects in locations such as the Atlantic Outer Continental Shelf region of the United States from Maine to Florida. 

Harnessing and converting wave energy off the New Jersey shore to electricity at an overall conversion efficiency of 24% (taking into account the hydrodynamics, PTO efficiency, generator efficiency, and power use during PTO winch rewind), results in the following output:

4,500,000 joules x 0.24/second = 1.08 Megawatts (MW) of annual average electricity production. This equates to 9460 Megawatt-hours (MWh) per year of grid-quality electric energy production. This calculation accounts for flat sea periods as more than 1.08MW will be produced during times when wave heights exceed 1 meter which will compensate for time when seas are flat. Historically, hours per year with waves over 1 meter high off New Jersey (at potential SurfWEC locations) are more than 10 times the hours per year when seas are flat.

We would like to thank all generous contributors for your past support of the New York Metropolitan Section Special Funding Appeal for past SNAME seasons. 


Our appeal for your generous support is especially urgent at this time as we face an increasing need to reach out to the New York Metro community at large regarding SNAME and the maritime industry as well as to keep meeting prices in check in the face of rising costs.

On behalf of SNAME NY Met Section, THANK YOU to the following Special Fund Donors for the 2018-2019 year:

 Dr. Walter Maclean, P.E.
Dr. George Williams
Mr. Martin Toyen
Mr. Raj Panda on behalf of Shesand Technologies


To make a Special Fund donation, please contact our Section Chair, Amit Mokashi.   We on the NY Met Section Leadership Committee thank you in advance for your thoughtful consideration of this request.
