The TGS | 4C Intelligence Platform is a specialist market intelligence platform for organizations working in offshore wind. Developing an offshore wind project requires understanding much more than where projects are located: companies need information on developers, turbines, cables, installation vessels, ports, contracts and project timelines to assess opportunities and supply-chain requirements. TGS | 4C brings these interconnected datasets into one platform, covering both operating and pipeline projects worldwide. It is aimed at offshore wind developers, suppliers, vessel operators, investors and other industry participants that need structured market information for project planning, competitor analysis, forecasting and commercial decision-making.

Core Features

The TGS | 4C Intelligence Platform is organized around specialist datasets covering different parts of the offshore wind market. Together, they allow users to examine a project itself and the equipment, infrastructure and services required to develop it.

  • Global Offshore Wind Farms: Provides intelligence on more than 3,000 installed and pipeline offshore wind projects worldwide, including project specifications, development status and timelines, stakeholders, contracts, events, auctions and leasing rounds.

  • Offshore Wind Turbines: Covers more than 250 turbine models, including technical specifications, manufacturers and power curves. Users can examine which turbines have been selected for projects and analyze market shares and technology trends.

  • Offshore Transmission & Cables: Tracks the infrastructure needed to move electricity from offshore projects into power systems, including export and array cables, offshore substations, converters, transmission systems and interconnectors.

  • Vessels & Ports Intelligence Service: Covers more than 2,000 vessels, including offshore wind logistics, construction, cable-installation and heavy-maintenance vessels, together with vessel specifications, contracts and charter activity.

  • GIS Spatial Data Suite: Provides geographic datasets that users can bring into GIS software to analyze where offshore wind infrastructure is physically located. Coverage includes 3,100+ wind farm boundaries, 30,000+ turbine positions, export and array cable routes, interconnectors and substation/converter locations.

Closing Insights

TGS | 4C's value lies in connecting parts of the offshore wind market that are closely dependent on one another. A developer considering a future project may need to know which turbines are available, whether suitable installation vessels and ports exist, how grid connections could be arranged and what competing projects will be demanding the same resources. Suppliers can approach the same database from the opposite direction, using project pipelines to identify future demand and commercial opportunities. TGS says its intelligence serves offshore energy developers, supply chains, investors and governments worldwide.

The underlying 4C Offshore intelligence business was acquired by TGS in 2021, adding its established offshore wind and subsea cable databases to TGS's wider energy-data portfolio. More recently, the business changed its name from TGS 4C Offshore to TGS | 4C as it expands its intelligence and consulting coverage beyond its traditional offshore wind and subsea cable markets.
