SIXTH FRAMEWORK PROGRAMME PRIORITY
6.1 SUSTAINABLE ENERGY SYSTEMS

• 019831 WAVE SSG
• Full-scale demonstration of robust
• and high efficiency wave energy
• converter

Project Objectives

• Design a full-scale 150 kW technical prototype of
  the MST turbine
• Manufacture, test and install a full-scale 150 kW
  prototype MST turbine into the SSG structure
• Design a full-scale 150 kW generator and control
  system equipment
• Measure performance data of the SSG wave energy
  converter including the structure in a period of
  up to six months for reliability and life time
  assessment.
• Test and install a full-scale turbine/generator
  and control system equipment for grid connection
  and annual production of 200,000 kWh of renewable
  and pollution-free electricity, corresponding to
  20,000 kWh/m
• Obtain a hydraulic efficiency of at least 39 for
  the shoreline application
• Obtain a wave-to-wire efficiency of more than 25
  during the test period
• Obtain 96 availability of plant (with regards to
  operational hours)
• Obtain 85 availability of production (with
  regards to wave climate)

Pilot Plant

• The pilot project is to be installed on the west
  coast of Norway on the island Kvitsøy which is
  known for its energetic sea state.
• The pilot structure is planned to be a 10 m wide
  module with approximately 150 kW installed
  capacity

Technology

• The SSG concept is based on the wave overtopping
  principle utilizing multiple reservoirs placed on
  top of each other.
• The potential energy of the incoming wave will
  be stored in the reservoirs before running
  through turbines and generating electricity.
• The patented multi-reservoir concept ensures
  that the all the different height of waves are
  utilized for energy production, resulting in a
  high degree of efficiency.

The SSG is built as a robust concrete structure,
where the turbine shaft and the gates controlling
the water flow are the only moving parts of the
mechanical structure.

Technology

• The SSG concept makes use  of the innovative
  patented multi-stage turbine (MST).
• The MST is specifically designed to further
  optimize the efficiency of the SSG converter.
• The special design turbine enables utilization of
  the different heights of water with only one
  turbine wheel.
• This will minimize the number of start/stop
  sequence on the generator resulting in a smoother
  energy supply to the grid and an increased
  overall efficiency.

Project Time schedule
The main objective of the project is to operate
at full scale one module of the SSG converter in
19 kW/m wave climate, including turbine,
generator and control system. One of the
objectives of the project is to measure
structural and technical data for obtaining
experience data for determining the reliability
of the technology. As the WAVESSG project is
among the prototypes in the field, through its
results, it may influence the political policy
and public awareness in EU and Norway towards
ocean energy and in particular wave energy. By
including Kvitsøy municipality in the consortium
and to establish a public exhibition centre at
Kvitsøy, the project will obtain public awareness
and backing. For the exploitation of the
results, Wave Energy intends to enter strategic
alliances with strongly positioned construction
companies with marine engineering experience in
costal countries in Europe. If successful, the
technology could be the basis for creating a new
industry with new jobs for Europe.
