What 4C Offshore does
4C Offshore, now operating as TGS | 4C, is a UK-based (Norwich/Lowestoft) market intelligence and consulting firm focused on the offshore wind sector. Founded in 2009 and now a subsidiary of US-listed energy data company TGS, the firm maintains a database of 3,616+ offshore wind projects across 60+ countries, covering wind resource, project status, ownership, supply chain, and subsea cable routing data. Its CEO is Chris Anderson. Named customers include Humber Work Boats Ltd, IHC Hydrohammer, and Global Marine Group.
The core product is a subscription-based Intelligence Platform that delivers offshore wind market data and analytics, supplemented by specialist subsea cable route consultancy services. In 2024 the company launched an upgraded platform with AI-powered generative summaries, an Onshore Wind Intelligence product line extending into the onshore wind vertical, and PowerPod, an industry podcast. The platform architecture is a structured project database with web-based delivery, layered insights, and tiered subscription packaging (Premium, Academic, Freemium).
The business model combines recurring SaaS-like subscription revenue across Premium and Academic tiers, a long-tail Freemium funnel, and project-based consulting fees for subsea cable route and feasibility studies. Go-to-market is primarily content-led (webinars, SEO, podcast, case studies) targeting offshore wind developers, operators, investors, supply-chain vendors, and academic institutions, with distribution leverage from TGS's enterprise sales channels.
