The amphibious transport ship Zr.Ms. Johan de Witt has almost reached the halfway point of its expected lifecycle. To guarantee its capabilities until 2032 and to keep the ship operational and relevant, it will receive a so-called midlife upgrade (MLU). As works must start at the end of 2021, on January 31st contracts were signed with Damen Schelde Naval Shipbuilding and RH Marine. RH Marine is specialised in maritime electrical and automation systems.
The preparatory phase is now ready and the contracts concern the basic design phase. This is followed by detailed engineering, after which work preparation and execution can start. For efficiency reasons, the MLU is combined with planned periodic maintenance.
In the basic design phase, more than 60 MLU modifications and the maintenance works are processed into a well-functioning overall plan. The modifications vary from installing additional weapon systems to solving structural problems. This also includes upgrading automation systems, networks, installing modern sports facilities and modernizing medical facilities.
Damen Schelde Naval Shipbuilding and RH Marine are carrying out the contract with the Defence Material Organization and the Naval Maintenance and Sustainment Agency, the maintenance branch of the navy.
