Project Development Support

Technical, consenting and financial feasibility: We support to align the right people forming a strong alliance for a successful project development. 

Technical Advisory

Getting the technicalities right can be the difference between an average and well-performing project.

Our advisory expertise spans analysis, risk management, due diligence, technical advisory and financial services - all of which come together to deliver better energy projects.

Owner Engineering

The management and coordination of the technical trades are key elements of large infrastructure projects. In these activities, the client representation (Owner's Engineering) plays a central role.
