Halli (899) is a modified, enlarged Hylje-design, and acts as a combined pollution cleanup and vehicle transport ship.

She is also operated by a civilian crew from the Ministry of Environment but is under Navy control.

The 11-metre (36 ft) bow ramp can be used to load or unload vehicles up to 48 tons.

As a cleanup vessel, she can sweep a 30-metre (98 ft) path at 1.5 knots (2.8 km/h; 1.7 mph) with her MacGregor-Navire MacLORI pollution collection system.
