The MoU aims to pave the way for more projects including the EU-funded EcoWindS research project, which was initiated by wind clusters in Denmark, England, Germany and Norway.
Under the terms of the MOU, the two firms will share best practice, ideas and non-confidential information, participate in and jointly sponsor projects and find opportunities for collaboration.
WAB managing director Ronny Meyer said: "Working together makes sense because we are probably the two biggest markets in the world and we have synergy and lots of potential between us.
"WAB, OrbisEnergy and Nwes already work together on the EcoWindS project and we would like to strengthen this collaboration."
OrbisEnergy business development manager Johnathan Reynolds said: "A growing number of our existing and graduate tenants have and are working on offshore wind projects both in the UK and in Germany. These include Seajacks who installed the 288MW Meerwind project, and more recently Fred. Olsen Windcarrier installing the 400MW Global Tech 1 wind farm."
