The Marineff project is a collaboration between France and the UK with the goal of developing coastal infrastructure to enhance and protect the ecological status of cross-channel coastal waters. Today, coastal infrastructure (such as the seawalls, quays, piers, groynes, and moorings) do not incorporate the enhancement of coastal and transitional water ecosystems.

The project aims to produce new ecological enhancement units to improve the ecological status of coastal and transitional watercourses, as well as professionals and stakeholders in the process. Improvements in the ecological status of the coastal infrastructure will be measured at a minimum of 15% compared to the original coastal infrastructure state.

The INTERREG VA France (Channel) – England co-funded by the ERDF and 9 French and British partners.

The partners, objectives, work packages… you will know everything about the Marineff project !

The MARINEFF project will be presented in Brussels!

On October 19th, 2022, the Speeding Up Nature Positive Offshore Energy Infrastructure Deployment conference will be held in Brussels.

The objective of this conference is to discuss the challenges and possible solutions to accelerate the deployment of offshore energy infrastructure while restoring European marine ecosystems.

The added value of the MARINEFF project in this conference is to raise awareness among stakeholders developing offshore wind energy with the issues related to the impact of electrical connections on biodiversity. Presenting MARINEFF will be an opportunity to show that before the deployment of infrastructures, it is possible to better plan the construction phases and limit the impact on the underwater environment.

Ecological Enhancement for Marine Infrastructure Workshop

On October 11th-12th, 2022, a workshop on the Ecological Enhancement for Marine infrastructures will take place in Bournemouth (UK). It is organised by the MARINEFF, SARC and 3DPARE projects.

Participation in this event is by invitation only.

This workshop will give the opportunity to exchange on the projects, the main results and the knowledge of each.

At the same time, the next SCM of the MARINEFF project will take place at the partner Bournemouth University.

Feedback on the submarine duplex on September 16th, 2022

A submarine duplex took place on September 16th, 2022 in Saint-Malo, organised by the partner MNHN of Dinard.

The extension of the MARINEFF project was an opportunity to propose a new format for the dissemination of environmental monitoring results!

The press and the partners of the MARINEFF project were invited.

We were on board of a SMPE (Saint-Malo Plongée Emeraude) boat, moored at a MARINEFF mooring on the Bizeux site and two divers were at a depth of 16 metres to show us and comment on the results of the project.
