R&D Cutting-Edge Contract Engineering Services

Ocean Wave Energy Harvesting

Electro Standards Laboratories (ESL) Contract Engineering Services Group has the ability to devise a solution and carry it from theory to product design, to manufacturing, testing, installation and operation. ESL's cutting-edge engineering solutions are based on over 30 years of technological experience and thousands of real-world applications. Because ESL has its own manufacturing capabilities, the ESL Engineering Services Group can design, build, and deliver custom products for each project in prototype or production quantities. This guarantees functionality and performance along with unsurpassed quality control.

ESL's R&D Engineering Services Group is significantly involved in a number of projects including Electromagnetic Aircraft Launch Systems (EMALS), hybrid electric vehicles and precision instrumentation. The ESL Engineering Services Group works as an extension of its client's R&D team and works from theory to simulation, design, development, programming, etc., to develop working systems. Electro Standards develops innovative products for commercial, industrial, and military applications.

ESL's R&D Engineering Services Group is involved in the design of Ocean Wave Energy Harvesting Systems designed for Sensor Buoys. The targeted applications for this technology include:

  • Recharging Stations for UUV (unmanned underwater vehicles)
  • Replacement for Solar Power
  • Augmentation of Solar Power
  • Elimination of Batteries
  • Sonar Listening Stations
  • Weather Monitoring Buoys
  • Wave Monitoring Buoys
  • Tsunami Warning Stations
  • Port Monitoring Buoys
  • Hybrid Battery/Super Capacitor Systems

ESL is addressing the need for extended operation of autonomous sensor buoys or other remote ocean platforms. Many existing remote ocean-based platforms currently are powered by batteries or by batteries in combination with solar power. As a solution to augment or replace any of these electrical-power-providing systems deployed in the ocean environment, power harvesting from ambient ocean wave energy becomes a natural and viable option.

Collaboration with the University of Rhode Island (URI) has produced two concept designs to address these needs. One concept is a direct drive system which provides power from the differential motion between the buoy float and a submerged resistant plate. The other concept is a resonant drive system which amplifies the generator' armature motion at the peak period of the sea state.

Scale model testing has been performed in the URI Department of Ocean Engineering wave tank as well as at the mouth of Narragansett Bay in Rhode Island. ESL model simulations have shown good agreement with scale model tests.

ESL's R&D engineering consultants have been involved in embedded controls, sensorless motor controls, multi-level inverters, controls modeling and simulation for motor drive systems, energy storage, and energy harvesting. ESL's R&D group is versed in using many types of DSP/microcontrollers to implement controls including TI DSP TMS320C3X, TMS320F24XX, TMS320C67XX, ADSP Sharc, Motorola 68HCxx, Infineon DSPs, 8xCXX, and more. ESL's R&D engineering group has designed structural controls to reduce bending or vibrations, PI controllers, advanced LQG, H-inf controllers, sliding mode controllers and much more.

ESL's engineering design team is also involved in precision instrumentation products involving strain gage or LVDT sensors, MIL spec cables and high-density fiber optics.
