Marsharcq participates in the construction of new military surface ships and submarines, for example the assembling and installation of piping networks in nuclear boiler rooms and traditional sectors of Barracuda submarines. On these most sensitive worksites Marsharcq copes with tight schedules requiring co-activities and adapted working hours while respecting safety, quality and environmental requirements.
SHIP MAINTENANCE
Marsharcq carries out maintenance works abroad on military surface ships and submarines that fall in the scope of complex naval sub-sectors, long-term framework contracts, drastic security and safety constraints and high-level technical requirements including in the nuclear domain. Furthermore, maintenance works must be adapted to operational imperatives which require responsiveness, availability and flexibility. Marsharcq particularly carries out the repair and replacement of valves, R&D missions including for specific tools, complex fabrications and planned shutdowns on vessels such as the SNA submarines and the Charles-de-Gaulle aircraft carrier.
