Summary
The Pelamis wave energy converter uses a novel joint and control system for power amplification in moderate seas and a benign state in severe seas. Its modular design enables cost-effective commercialization.
Area of Science:
- Marine Engineering
- Renewable Energy Technologies
- Oceanography
Background:
- The Pelamis wave energy converter (WEC) has evolved from concept to commercial deployment.
- Early designs prioritized survivability and power absorption, leading to an articulated line-absorber in an attenuator orientation.
Purpose of the Study:
- To review the development of the Pelamis WEC.
- To present second-generation designs and discuss future enhancements.
Main Methods:
- Active tuning of joints and control systems for resonant power amplification in varying sea states.
- Hydraulic rams for power take-off and high-pressure accumulators for smooth electricity generation.
- Land-based modular construction for efficient offshore installation.
Main Results:
- A novel joint and control system allows active tuning for power amplification in small to moderate seas.
- In severe seas, the device defaults to a benign, non-resonant condition.
- Modular construction facilitates rapid offshore installation, crucial for commercial viability.
Conclusions:
- The Pelamis WEC's design incorporates features for both power optimization and survivability.
- Second-generation designs have been developed, with scope for further cost reduction and performance improvements.
- The engineering approach supports viable commercialization of wave energy.
