To Freeze Dredge 600m2 in the Hällevik Harbour in the south of Sweden. The Hällevik Harbour is a Blue Flag marina with high environmental standards and the FriGeo Freeze Method was chosen by Sölvesborg Municipality due to its cost-effective and environmentally friendly benefits. The dredging work carried out by FriGeo has contributed to a better environment in both the Hällevik Harbour and the surrounding Baltic Sea.

Here you can find brief information about a few of our completed projects.
Hällevik Harbour, Sövlesborg, Sweden
Högbytorp, Upplands-Bro, Sweden
A pilot project to freeze dewater oil polluted sludge at the Ragn-Sells recycling and remediation plant in Högbytorp. Via our mobile freeze plant the unique FriGeo freeze technology is applied to reduce sludge volumes and thereby facilitate handling and remediation work. Ragn-Sells is Sweden’s leading recycling and remediation facility with operations in six countries across Europe.
Stockviksverken, Sundsvall, Sweden.
To remove mercury-contaminated sediments in a 2700m2 large sea bay polluted by the process water of a nearby chemical plant. Through the FriGeo method of freeze dredging the contaminated sediments were safely removed from the seabed and transported to a remediation facility for further treatment.
Vassaraträsk, Gällivare, Sweden.
Lake Vassijaure, Kiruna, Sweden.
To freeze dredge the alpine lake of Vassijaure in Swedish Lapland with the purpose of removing oil-polluted sediments. Through freeze dredging it was possible to minimize turbidity and prevent the dispersal of material during removal.
The Baltic Sea
To stabilize the wreck site of a military DC-3 aircraft on the seafloor of the Baltic Sea, at a depth of 125m. After stabilizing the bottom sediments via freeze technology, pieces of the 1952 wreckage were salvaged in a frozen state and transported to a forensic investigation carried out by the Swedish Police and the Swedish Accident Investigation Board (SHK).
Muskö Naval Base, Haninge, Sweden
To remove contaminated sediments in a tunnel at the underground Muskö Naval Base as part of an environmental impact investigation conducted by The Swedish Defence Research Agency.
