The Norwegian Institute of Marine Research has given its support to Fiskebåt in its complaint about the conditions for Hywind Tampen. Fiskebåt had directed criticism at the proceedings in the Norwegian Environment Agency.

In the complaint Fiskebåt stated that the Hywind Tampen wind power plant is the first offshore wind plant to be established in Norwegian waters, with construction work just started. Fiskebåt therefore believes that it is very important that this is done properly, and that relevant information and knowledge is gathered about any consequences such a development may have for the environment, stocks, ecosystems and fisheries. Since this is the first major development, the results of such investigations can also be used on a larger scale. This has now received the support from the Institute of Marine Research.

In a letter to the Norwegian Environment Agency, the Institute of Marine Research writes, among other things:

“The Norwegian Environment Agency has received a complaint from a fishing boat about the decision on permission for the Hywind Tampen wind farm. The Institute of Marine Research agrees with the statement in the complaint that the advice from HI regarding the development of offshore wind has not been sufficiently followed, and recommends including the following conditions for implementation in the permit based on our advice:

“Carry out monitoring of marine organisms (fish, zooplankton, marine mammals) in the area, as well as monitoring of the noise level in the wind farm area. This is recommended to be done using echo sounders with at least two frequencies and hydrophones with recording over a wide frequency spectrum, to capture both noise from wind turbines and vocalizations in marine mammals. If necessary, measurements can also be made with ADCP.

“That the structures are removed after the end of operation.

“That materials are used in the mooring that create the least possible noise when the turbines move.”

The Directorate of Fisheries also agrees with the Fiskebåt’s complaint, and writes the following in its input to the Directorate of the Environment:

“We support the assessments made by Fiskebåt and request that the discharge permit be updated on the basis that new advice has been received from the Institute of Marine Research and that special requirements are set for the clean-up and removal of installations after operation has ended.

We ask that the discharge permit be updated with the following additional conditions (cf. Fiskebåt’s letter to the Norwegian Environment Agency dated 22 June 2022):

  1. The Norwegian Environment Agency sets requirements for monitoring fish in the area, including the installation of echo sounders in relevant areas with at least two frequencies and hydrophones that pick up a wide frequency spectrum in the area. Collected data must be openly available.
  2. The Norwegian Environment Agency requires the structures to be removed after the end of operation.
  3. The Norwegian Environment Agency requires that materials are used in the mooring of floating wind turbines that create the least possible noise when the turbines move, for example to avoid jerking and snagging in the anchor chains.”
