On the main deck the built and deployable. The vessel is equipped with a compact 9-man in-built Saturation Diving System rated to 300 msw. The vessel MRSV hosts the Drass Submarine Rescue Capsule SR 11 Type and Drass Submarine Ventilation System (deployable version) to hosts an in-built Drass Submarine Ventilation System rated for 650 msw and a Working ROV. This vessel design is suitable to operate perform rescue operations for the DISSUB. The MRSV is also equipped with two stern lifting arms connecting each to a 60 ton winch. in extreme sea conditions (SS5). Each winch is capable to perform submarine salvage operations, lifting a flooded Drass DG160 Midget Submarine from the seabed and recovering it to the semi-submersible drydock for transportation ashore.
