The cargo vessel CF Liljevalch was part of a convoy that transported iron ore from northern Sweden to Germany in 1942. But outside Västervik, the ship was torched by a Russian submarine and sank very quickly. Only seven people survived in the crew of about 40 men.
Since then she has been at the bottom of the sea - at 60 meters deep. Divers have been at the wreck but no one has known exactly how the wreck looks until now.Finding everything possible
The ship Jacob Hägg conducts a comprehensive survey of marine waters in commercial shipping. Right now, the seabed is sailing along the Småland coast and Östgötakusen.
- We find both unknown and known wrecks, says Magnus Wallhegen, Production Manager at the Maritime Geography business area at the Swedish Maritime Administration.Unique 3D images
They use an advanced sonar that sends out thousands of rays, from the measuring points they can compile a unique 3D image that shows exactly how the wreck lies.
- In the pictures of CF Liljevalch you can see how the wreck stands on the bottom, what the cab looks like and that the mast has collapsed.
The images are sent to the National Marine and Transport Museum and the National Antiquities Office. They analyze the images and provide valuable facts to a knowledge bank built around Swedish wrecks.
Divers and archaeologists are also interested in the images.
