The US Bureau of Ocean Energy Management (BOEM) said the MOU recognizes common interests of the two countries in developing the technology as a clean and sustainable energy source.
Under the terms of MOU, the counties will focus on priority areas including sharing best practices, policy initiatives, financing and risk management challenges as well as technical knowledge transfer.
BOEM director Abigail Ross Hopper said: "This is a historic event for our respective countries as we work together to share knowledge, experiences, data and best practices relevant to offshore wind energy development.
"This MOU represents an exciting milestone toward a achieving a clean energy future."
As per the deal, the countries will work together to share knowledge on a range of offshore wind energy issues including supply chain, offtake, grid integration/interconnection, and system planning to optimize offshore wind energy deployment.
In addition to sharing data on the benefits of offshore wind energyand strategies for achieving cost reductions, the countries will identify and discuss financing and risk management challenges for offshore wind energy facilities.
Danish Ambassador Lars Gert Lose said: "This agreement is a testimony to the strong Transatlantic ties between."
"Denmark has been using offshore wind power as an energy resource for 25 years and I am delighted that we – by sharing our knowledge and experience – can help promote renewable energy in the world’s largest economy."
