This rigorous approach means that we are able to offer our clients turnkey solutions which guarantee that their projects can be carried out in the utmost respect of deadlines and safety requirements.
MODIFICATION AND UPGRADE PROJECTS
Thanks to our centralised project department, which allows us to capitalise on feedback from our interventions, and our agency network which ensures complete geographical coverage of French nuclear power plants, Marsharcq fully masters the implementation of modifications and upgrades required by operators. Furthermore, our design capabilities, enhanced by our experience in the field, enable us to be source of proposal to support the performance of these solutions, therefore participating in the continuous improvement of facilities.
