Operating Principle

At its simplest, SPERBOY™ is a floating buoy with an oscillating water column inside. Part of the device is always underwater, and on top of the buoy are turbines, generators, and associated system facilities. 

As SPERBOY™ is moved by the waves, the oscillating water column generates energy which is then transmitted to the mainland for distribution. 
Thanks to the innovative and pioneering design of the SPERBOY™, it has four key competitive advantages:

• it is capable of simple and easy deployment in deep water to maximise the greatest energy source
• its entire body floats, which means that it maintains the perfect angle to produce high energy capture at minimal cost.
• it is environmentally friendly, producing no greenhouse gases and slowing coastal erosion
• it requires low maintenance, making it easy to set up and then leave to generate energy

Deployment procedure

1) First we install anchors onto the seabed
2) Then we lay shore-to-farm cables to transmit the generated energy
3) SPERBOY™ is then deployed out into the ocean
4) The device interconnecting cables are then laid
5) SPERBOY™ is commissioned and starts generating clean renewable energy.

Infrastructure required

SPERBOY™ requires very little in terms of permanent infrastructure. The main body can be manufactured in a location close to the site, and then transported and deployed by suitable vessels. All the skills required are similar to most offshore sectors and can be introduced as required. The location will determine the actual infrastructure required.

The off-shore farm

Current work is based  on the projections of the deployment of a 90-device farm. When the commercial models are created, however, the optimum for commercial and operational considerations will be up to one thousand SPERBOY™s with around 350 metres between them, covering an area of 10 – 15 square kilometres.

Maintenance required

Routine maintenance would be carried out while SPERBOY™ is at sea. The device has a modular design, and so any parts can be exchanged simply. The design aim is a zero-maintenance requirement.

An appropriate support vessel with the necessary maintenance capability, but many vessels have the capacity to be used without extensive modifications.
