Operation & Maintenance

Since WaveRoller doesn't require any fuel, the main cost drivers during the life of a project are operation and maintenance. WaveRoller addresses these issues with a smart design that combines proven submarine technology with remote condition monitoring and control systems.

Maintenance always on surface

WaveRoller units can float without any external support. This feature makes it relatively cheap and easy to tow the devices to and from the project site. We deploy the units by flooding the ballast tanks with water - causing the device to sink to the sea bed where it can commence normal operations.

For service or maintenance, we simply pump air back to the ballast tanks, so that the WaveRoller unit can rise to the surface. Operators can then access the machine rooms directly on site or tow the device to a suitable location closer for maintenance work. This intelligent design also allows us to address a very important health & safety issue.

Remote condition monitoring & control system

The WaveRoller unit is controled remotely, making it possible to access device performance and condition data in real time from multiple locations around the globe. This data is collected via an array of sensors located inside the device. In addition monitoring the quality of the power output, remote monitoring provides data about the conditions inside the device and the behaviour of its individual components. The performance and condition data serve for many purposes.

  • To identify any potential faults or maintenance needs
  • To adjust the WaveRoller to respond to the sea state and ensure optimal power output the prevailing wave conditions
  • To collect data for long-term performance analysis
  • To provide data for R&D inputs for future generations of WaveRoller
