Process-Fluid-Lubricated Polycrystalline Diamond Bearings for application in Marine Hydrokinetic Machines

Sexton T.N., Cooley C.H., US Synthetic Corp., US

Polycrystalline diamond thrust and radial bearings have proven to be successful in harsh environments, such as those encountered in down-hole oil and gas drilling tools. They are particularly well suited for applications where a harsh [...]

Offshore Renewable Resources – Improving the Cost-of-Energy

Roznitsky S., HighSeasWind, US

The U.S. has an abundance of wind and wave offshore resources suitable for industrial-scale power generation, the best resources are in deep waters. Cost-of-Energy (COE) is defined as Production Facility’s Total Costs (C) divided by [...]

Offshore Wave and Wind Together – Afloat

Brown N.A., Float Incorporated, US

Offshore wind and wave power are, or can be, remarkably complimentary. Given a stable floating platform to share, important economies of renewable power production and storage are possible. (A figure shows how wind and wave [...]

Mobile Wave Energy Harvesting System

Sharon A., Briggs J., Wirz H., Boston University - Fraunhofer CMI, US

Conventional approaches to harvesting energy from ocean waves and currents suffer from at least three major drawbacks: 1) expensive underwater power transmission cables, 2) storm damage susceptibility, and 3) energy output is not delivered at [...]
