Project Summary – Goals and Outcomes
The project Balanced Wave Energy Converter (BWEC) is a groundbreaking initiative in ocean energy, developed to make wave power a stable and cost-effective energy source. The primary goal has been to develop a system that combines high operational reliability with efficient energy production—without requiring complex or expensive installations.
BWEC consists of three main units – storm buoy, submerged buoy, and seabed installation – which together form a balanced system for energy utilization. Under normal operation, the system converts the vertical movement of waves into electrical energy via two generators, each of 25 kVA, located in pressure compartments on the seabed module. In extreme weather conditions, the storm buoy can be pulled underwater to protect the system, making the technology especially robust and suitable for challenging waters.
Tests have shown that the concept functions as intended, with stable energy production and good operational reliability. This paves the way for further development and scaling up of the technology.
Innovation and Technology
What makes BWEC unique is the combination of simple mechanical construction and intelligent control. The system is designed for balanced movement, where the forces from the waves are optimally harnessed without unnecessarily stressing the components. This reduces maintenance requirements and increases the longevity of the equipment.
Each unit is constructed from robust materials – including strong GRP (glass-reinforced plastic) and steel – with an integrated ballast system, winch, and control system for the storm buoy. This makes BWEC both flexible and scalable for various ocean depths and locations.
Collaboration and Development
The project is developed by Ocean Energy AS, in collaboration with West Maritime AS and MetalCad d.o.o.. The collaboration has combined expertise in maritime technology, mechanical design, and renewable energy. Together, the partners have developed a concept that can help make ocean energy more accessible and commercially viable.
Long-term Impacts
BWEC represents an important step towards a more sustainable energy future. By extracting energy from waves – a constant and predictable resource – the system can contribute to increased production of green energy globally. The technology has the potential to supplement both wind and solar power, thereby strengthening energy security in coastal communities.
In the long term, the solution could also form the basis for new standards in wave power and inspire further research and commercialization in marine energy extraction.
Summary
BWEC demonstrates how Norwegian technology and maritime expertise can be translated into concrete solutions for the green transition. With a design that withstands natural forces and utilizes them in an intelligent way, the project points towards a future where the ocean is not only a thoroughfare but also a power source for new, sustainable energy production.
