What TIS GmbH | Testing & Inspection Services does

TIS GmbH (legally T.I.S. GmbH | Testing & Inspection Services) is an independent, owner-managed consulting firm headquartered in Berlin that serves the offshore wind energy sector. Founded in 2000, the firm delivers an integrated portfolio of professional services spanning project management, construction site management, document verification, quality management, and QA/QC coordination. Underlying capabilities include welding and coating surveillance for offshore substations (OSS), monopiles, jackets, and transition pieces; non-destructive testing (NDT) including Time-of-Flight Diffraction (TOFD); non-conformance report (NCR) and technical query management; and corrosion protection consulting for offshore foundation structures.

The firm generates revenue through professional services engagements sold directly to enterprise clients. With 9 employees and 200+ projects supervised across Germany, France, the UK, Belgium, Denmark, Poland, the Netherlands, the USA, and Taiwan over more than two decades, TIS operates as a high-touch boutique. Its go-to-market is enterprise field sales targeting major European transmission system operators (50Hertz/Elia Group, TenneT), wind developers (Ørsted, EDF Renewables, Iberdrola, EnBW, E.ON, Atlantic Shores, Global Tech 1), and foundation manufacturers (Steelwind Nordenham). Pricing is bespoke and project-specific; no public pricing is disclosed. Marketing is limited to a multi-language company website, LinkedIn presence, and industry event participation, with bottom-of-funnel conversion driven by direct consultation requests.

Scale indicators3 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• RINA: Italy-headquartered TIC and engineering consultancy with an offshore wind certification and inspection offering. Comparable because RINA performs welding surveillance, NDT and certification on offshore wind foundations — the same service mix TIS provides.
• Worley: Global energy, chemicals and resources project services provider with offshore wind owner's engineering, EPC support and inspection services. Comparable for project management and QA/QC on offshore wind projects, though as a broad energy-services incumbent.
• TÜV SÜD: Major German TIC provider with energy and offshore wind inspection services including welding, coating and NDT. Comparable because TÜV SÜD competes for QA/QC mandates on the same offshore wind projects TIS serves, particularly across German and European markets.
• SGS: World's largest TIC company with inspection, testing and certification services across energy infrastructure including offshore wind. Comparable for inspection and QA/QC scope, but competes as a diversified mega-incumbent rather than an offshore-wind specialist.
• Bureau Veritas: Global TIC incumbent with significant offshore wind inspection, certification and owner's-engineering activities. Overlaps directly with TIS's QA/QC and welding/coating surveillance scope, particularly on European offshore wind projects, but operates across all TIC verticals.
• Intertek: Global TIC and quality assurance provider with offshore wind and renewable energy inspection offerings. Comparable for QA/QC, NDT and project oversight services, though as a broad incumbent serving many industries beyond offshore wind.
• DNV: Global TIC and certification major with a dedicated offshore wind practice covering type certification, project certification and QA/QC. Comparable because DNV competes for many of the same offshore wind QA mandates that TIS executes, but at vastly larger scale and broader scope.
• TÜV Rheinland: Global TIC incumbent with energy infrastructure inspection and certification services, including offshore wind. Directly comparable service portfolio (welding surveillance, coating inspection, project certification) but operates across a much wider TIC mandate.

Direct peers

• Fichtner: Germany-based engineering consultancy serving energy infrastructure including offshore wind with owner's engineering, project management and QA/QC services. Closely comparable business model and customer base to TIS, with greater scale and broader engineering scope.
• Mott MacDonald: Global engineering consultancy with a strong offshore wind owner's engineering and advisory practice. Comparable because Mott MacDonald performs project management, construction oversight and QA services for offshore wind developers — a direct adjacency to TIS's core offering.
