A project has to clear three gates to move forward

Policy design, execution reality, and the bankability test. Each of DeepWind's six research areas looks at one of these gates.

Gate 1Policy design

Do the auction rules leave room for a viable project?

Policy & RegulationWe assess how offshore wind laws, FIP rules, auction design, and evaluation criteria affect project formation and viability.Read the analysis → Market DynamicsWe analyze Japan's offshore wind market direction through auction outcomes, developer activity, and supply-chain signals.Read the analysis →

Gate 2Execution reality

Are there enough ports, vessels and factories to build it on schedule?

Project ExecutionWe evaluate execution constraints across ports, vessels, foundations, supply chains, and project schedules.Read the analysis → Floating WindWe analyze floating offshore wind through port readiness, installation risk, supply-chain capacity, and cost structure.Read the analysis → Technology & SystemsWe assess how turbines, foundations, installation methods, grid systems, and O&M affect market competitiveness.Read the analysis →

Gate 3Bankability test

On those terms, will a bank lend?

Cost & Commercial ViabilityWe examine project viability through LCOE, CAPEX, OPEX, IRR, and financing assumptions.Read the analysis →

Find a zone, test it, follow it

Find a zone on the map, test what it takes to get financed in the simulator, follow the changes every week in the Weekly, and read the full reasoning in the reports. The four work as one path.
