site evaluation

Site evaluation

Each site is different from the previous ones, and it is needed to undertake a site study before the tidal power array can be planned. Such assessments incorporate:

 

 
  • Water depth
  • Current velocity, profile and directions
  • Bathymetry
  • Wave and turbulence impact
  • Grid connection
  • Environmental issues

 

Water depth:
The tidal technology is designed to be installed at 40-100 meters depth.

 

Current velocity, profile and directions:
The technology is designed to generate cost effective energy from 2.5 m/s.
It is necessary to have knowledge of the current profile and up-stream/down-stream directions to design a tidal power array.

 

Bathymetry:
It is important that the project developer has good knowledge of the bathymetry at the site. The technology is tailored to suit most situations

 

Wave and turbulence impact:
The waves which influence the current deeper than ten meters are of interest to be able to evaluate if the waves may influence the installation.

 

Grid connection:
Access to the grid is essential for delivering electric power.

 

Environmental issues:
Stakeholder assessment, including e.g. fishing and ship traffic, as well as environmental assessments, including e.g. sea mammals, fish, seabirds and other marine life, need to be studied.
