The MoU is intended to pave the way for more projects such the EU-funded EcoWindS research project initiated by wind clusters in Denmark, England, Germany and Norway.
Both the parties will share best practice, ideas and non-confidential information, participate 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: "We hope there will be stronger relationships for our business communities, collaborative relationships between OrbisEnergy and WAB, and new projects that will help the offshore wind industry in our own respective countries.
"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."
