She is a Tripartite Mine Hunter (CMT)and specifications per the Belgian Navy web site @
Dedicated to mine countermeasures operations:
Sweeping of anchorage mines
Hunting of bottom anchored mines
Special studies have shown the feasibility to construct the hull entirely of "GRP" (Glass Reinforced Polyester) because mine countermeasure vessels should have low magnetic signature and be shock resistant.
The radio equipments are in accordance with Nato requirements.
The airconditioning and the pressurization system ensure a safe passage through an NBC contaminated area.
