DH renewables have provided 6 technicians to Hornsea 2 Preassembly site over the last year. The team that has been provided is technically gifted, driven, committed and reliable working to exceptionally high standards of quality and professionalism. The interactions we have had with the company have been of the highest order and certainly show the high standards and high level of professional courtesy we would expect here at SGRE. This is a company that is on rise with its elevated standards and team of reliable and technically gift people. The sky is limit for them going forward! I will personally be recommending that we use this company again here at SGRE on future Offshore preassembly projects. Thank You DH Renewables it has been a pleasure working with you on the Worlds Largest Offshore Wind Farm Hornsea 2!!

DH Renewables has contributed significantly to the success of multiple of our onshore projects. I have been working closely with DHR on a daily basis for a period of 6-7 months. The technicians they offer deliver additional experience, knowledge and expertise to the team. In addition, they have the right mindset at work and have proven to be able to easily adjust to our team and site conditions. Working together with Dan and his team has been effective and pleasant thanks to their flexibility, quick reaction times, and thinking along towards solutions in all kind of situations. DHR brings a wide portfolio of qualified personnel which maximizes the likelihood of finding matching personnel for the needs on a project.
