Your local partner at Fehmarn Belt

The construction of the Fehmarnbelt Tunnel is well underway and steadily approaching the 2029 deadline. While involving numerous foreign and local contractors operating at sea and ashore, technical challenges are an inevitable part of the work progress at each state. This creates a demand for production and manpower support.

With SH Group, you are ready to meet this demand. We are an engineering company with newly established facilities and a technically highly qualified support team, and we specialise in steel, hydraulic, mechanical, and electrical engineering.

Help at sea and ashore

“We provide customised solutions and take care of all service aspects like maintenance, modifications, overhaul, testing and installation on machinery and equipment on cranes, dredging vessels, production plants etc. Logistically we are used to operating both ashore and at sea above and deep below the waterline,” explains Klaus Rasmussen, Site Manager Rødbyhavn.

“Some Fehmarn Belt contractors, especially foreign, may lack the resources to manage projects involving different professional groups. Based on hundreds of projects, we have developed strong recruiting, managing, and cooperation skills with various subcontractors needed for a specific project. We are currently building strong relationships with qualified local businesses to leverage large projects for companies working at the Fehmarn Belt construction site”.

One call does it all

When needing urgent technical support, a customised solution or help to launch a specific project, the “lifeline” is just one call away. SH Group operates by the principle of “One-call-does-it-all” to ensure that companies in need get help quickly and easily.
