Selected as environmental consultant for the Fehmarnbelt Fixed Link
As leader of the Fehmarnbelt Environmental Monitoring and Consultancy (FEMO) consortium, we signed a DKK 300 million framework contract with Femern A/S on Friday, 28 November 2014.
The Fehmarnbelt project will establish a fixed link (an immersed tunnel) between Northern Germany and Denmark across the Fehmarnbelt. We previously worked with other partners and Femern A/S (which is in charge of planning the fixed link) to examine the environmental impacts from the construction works and permanent structures. As part of the Environmental Impact Assessment (EIA), we conducted baseline monitoring for two years, as well as an in-depth impact assessment of three possible options: an immersed tunnel, a suspension bridge and a bored tunnel.
Over the next seven years, we will monitor the environmental impacts of construction activities on the sea, air and land to ensure compliance with the limits set by the authorities. FEMO activities may include:
- operating a hydrographic monitoring system with two main buoys and several nearshore buoys
- quality assuring sediment spill data from the expected 19 million m3 of dredging works
- monitoring underwater sound and impacts on marine mammals
- monitoring sea bird, flora and fauna impacts
- monitoring coastal and seabed morphology impacts
- monitoring noise, dust and vibrations on land
- designing and developing compensatory nature elements on land, including a new lake
- assisting with ad-hoc assessments for coming adjustments in the project compared to the basis for the previously performed EIA
- conducting activities related to final plan approval in Denmark and Germany
In addition to our DHI Denmark office, the FEMO consortium also includes Orbicon (Denmark), BioConsult SH (Germany) and MariLim (Germany). Sub-consultants on the project include DHI Germany, DHI-GRAS (Denmark), NIRAS A/S (Denmark), Institut für Technische und Angewandte Physik GmbH (Germany), WTM Engineers (Germany), Müller-BBM (Germany) and Fiskeøkologisk Laboratorium (Denmark). FEMO’s work for the construction phase of the Fehmarnbelt project began 1 December 2014.
