Chemical plant
On 24 December 2011 "Louhi" and "Linja", another Finnish spill response vessel, were dispatched to the Gulf of Bothnia as a precaution after a tall oil spill from Arizona Chemical plant near Söderhamn in Sweden. While Sweden had not send an official request for assistance yet, the Finnish recovery ships prepared to join the spill combating operation if the oil slick, at that time some northeast from Söderhamn, started drifting towards the Finnish coast. Although "Louhi" can operate in relatively high seas, the recovery effort was hindered and subsequently the oil slick was broken up by the storm on 27 December 2011. When "Louhi" moved to the recovery area on 28 December, the slick could not be located and only of weathered oil was recovered.
