She is also operated by a civilian crew from the Ministry of Environment but is under navy control. The vessel can act as a landing ship and logistic support vessel. The 11 m bow ramp can be used to load or unload vehicles up to 48 tons. As a cleanup vessel, she can sweep a 30 m path at 1.5 kn with her MacGregor-Navire MacLORI pollution collection system. The vessel is equipped with a 360 m³ waste-collection tank. The ship was built in 1986 and refitted in 2010.
