There was a huge demand in fast, mobile and modern task forces in the field of ship inspections and ship bottom cleaning in 1968 already. Thus, it was a logical conclusion for Leopold Krüger and Claus Günzlein to found Hansadiver. The company was able to position itself in this segment due to the permanently high quality of the performed works. It could also expand into the area of construction site diving and services for public authorities, shipyards, shipping companies and civil engineering companies within a short amount of time.

We played an indispensible role in several Hamburg projects like the construction of the Elbe Tunnel in 1970 and 2001, the expansion of all container terminals as well as the construction of ship lifts and locks.

Hansadiver extended its range of services through continuous training and adaptation to the clients’ increasing demands. Specially trained divers for the
disposal of explosive ordnance and location clearance managers have been operating on behalf of our clients since 2003. Crane and survey ships with qualified
personnel were part of the foundations for the conclusion of a framework contract with the explosive ordnance disposal unit of the Free and Hanseatic City of Hamburg.

At the same time, the segments of ship and structure inspection, repair works and certified underwater welding have developed very well. The field of activity extended significantly due to the foundation of GSS Hansa Offshore GmbH in 2013.
After having completed many successful projects, we are now able to benefit from an international network and extensive experience. We were certified by Shell in 2013,
followed by the GL certification as specialized company for underwater welding in 2014.

We train our divers, inter alia, in welding and inspection of underwater structures and vessels.

Hansadiver’s basis and offices have been located at the Norderelbe since 1982, including an own port facility since 2010. This central location ensures immediate readiness in Northern Germany.

Since 2016, Hansadiver has its own fleet base in the Berlin and Brandenburg area in Eastern Germany.
