Multi-year contract for modernisation of submarines

The Dutch Defence Materiel Organisation granted Imtech Marine Netherlands the assignment to carry out the mechanical, engineering and electrical upgrade work on board the submarines, which will be done at the Naval base in Den Helder and will run from 2013 until 2020. IP-W includes a large number of modifications, such as disassembly, assembly and installation of a variety of equipment and systems to ensure that the submarines will remain effectively operational in service until at least 2025.
In addition to extensive conservation work, the programme comprises the replacement of the sonar installation, the replacement of the periscope system by an optronic mast, the replacement of the combat management system and internal communication system, modification of a number of platform systems and the complete redesign of the central radio cabin and electronic cabin. Imtech Marine says it will also be involved in the installation of the SATCOM systems and the delivery of new consoles for the redesigned combat information centre.
