When cutting-edge technology meets precise heavy-lift logistics, projects of special significance are born.

The “Mammut” (PK135) loading crane from Gustav Seeland GmbH in Hamburg supported the test runs of the underwater drone

“GreyShark” in the Baltic Sea off the coast of Wismar. With a planned load of 8 metric tons, the system was tested and safely deployed into the water.
