In October 2011, the sailing ship Alexander von Humboldt II started its service and has been conquering the seas ever since. The ship, operated by the German Sail Training Foundation (DSST), is a barque rigged with three masts. The masts and hull consist of steel.
It is the first new vessel of a German tall ship after the construction of the Gorch Fock, the training ship of the Navy. On the Alex II, you can enjoy sailing trips lasting one or more days or learn to sail on special training trips.
HB Hunte Engineering GmbH was responsible for the construction of the new ship. Marine Engineering Wollert GmbH performed calculations of the rigging (the masts and the cordage holding the masts) as well as strength calculations of the hull. Both have been Dlubal customers for many years and use RFEM for their analyses.

The "Base Plate" component allows you to design base plate connections with cast-in anchors. In this case, plates, welds, anchorages, and steel-concrete interaction are analyzed.
