What mh² offshore does

mh² offshore GmbH is a privately held, owner-managed German specialty services company focused exclusively on the offshore wind energy sector. Headquartered in Loxstedt-Stotel, Lower Saxony, the firm delivers an integrated portfolio of five core service lines: welding technology (Schweißtechnik), periodic inspections and testing (Inspektionen & Prüfung), steel construction, assemblies and repairs (Stahlbau, Montagen & Reparaturen), rope access technology (Seilzugangstechnik), and engineering & consulting. Services span the full lifecycle of offshore wind structures—foundations, transition pieces, jackets, and offshore substations (OSS/OHVS)—from installation and commissioning through recurring integrity inspections and repair campaigns.

Underlying technical capability rests on certified human execution: FISAT Level 2/3 rope access enables work in difficult-to-reach areas without scaffolding; EN 1090 EXC3-certified welders cover SMAW (111), MAG (136/138), and TIG (141) processes with in-house application-specific procedure qualification; NDT Level 2 inspectors (VT, MT, PT per ISO 9712) and FROSIO Level III coating inspectors deliver inspection completeness in-house. The company is structured around three managing directors and co-owners: Markus Hummel (CEO, ISO 17024 expert for offshore steel structures, MSc Offshore Technology), René von der Hellen (CTO, International Welding Engineer), and Jens Metzen (COO, International Welding Specialist and FISAT Level III).

The business model is B2B, sales-led, project-based professional services with quote-based contracts. Revenue is generated through direct contracts with offshore wind farm operators (EnBW, RWE Renewables, Vattenfall, Trianel, Global Tech I, Merkur), TSOs (TenneT at HVDC platforms), and EPC contractors (Siemens Energy, GE Grid, Semco Maritime). Projects are recurring inspection mandates and discrete modification/repair campaigns delivered with the company's own qualified personnel—no subcontracting layer. The company maintains the full sector-mandatory certification stack (ISO 9001/14001/45001 by Lloyd's Register, ISO 3834-2, EN 1090-2 EXC3, Safety Culture Ladder Step 3) and operates exclusively in German North Sea and Baltic Sea waters.

Core offering

mh² offshore GmbH is an owner-managed German service company that delivers offshore steel construction, certified welding (SMAW, MAG, TIG), non-destructive inspection, rope access (Seilzugangstechnik), and engineering consulting for offshore wind farm foundations, transition pieces, jackets, and offshore substations. Services span the full lifecycle of offshore wind structures — from installation and commissioning through recurring inspections, repairs, and modifications — primarily in German North Sea and Baltic Sea waters.

Product overview

mh² offshore GmbH is a service company offering an integrated portfolio of five core service offerings for the offshore wind energy sector: Welding Technology, Inspections & Testing, Steel Construction Assemblies & Repairs, Rope Access Technology, and Engineering & Consulting. These services are designed to support all lifecycle phases of offshore wind structures—installation, commissioning, and operations—from planning through execution to documentation. The company combines these individual services into project-specific service packages, enabling independent project implementation from operations planning and document preparation to offshore installation, inspection, welding, and final documentation. Services are performed using rope access techniques for difficult-to-access areas.

Products and services

• Schweißtechnik (Welding Technology) Offshore welding services for tripods, jackets, substations, and transition pieces, performed by certified welders (SMAW 111, MAG 136/138, TIG 141) under supervision of in-house welding engineers, including weld seam documentation and non-destructive testing. Targeted at offshore wind farm operators, developers, and EPC contractors.
• Inspektionen & Prüfung (Inspections & Testing) Periodic inspections of weld seams, bolted connections, and corrosion protection on offshore wind turbine foundations, substations, and transition pieces, performed by qualified inspectors using visual inspection (VT2), magnetic particle testing (MT2), and dye penetrant testing (PT2) per ISO 9712 standards. Includes expert inspection services per ISO 17024. Targeted at offshore wind farm operators.
• Stahlbau, Montagen & Reparaturen (Steel Construction, Assemblies & Repairs) Steel construction services including assembly, disassembly, and repair work on offshore structures such as boat landings, ladders, railings, and large component replacements (transformers, switchgears), with associated method statements and risk analyses. Certified to EN 1090 EXC3. Targeted at offshore wind farm operators, developers, and EPC contractors.
• Seilzugangstechnik (Rope Access Technology) Rope access technique services enabling work at difficult-to-access locations on offshore structures, with technicians trained to FISAT Level 2 and Level 3 standards, used for assembly, inspection, and welding work. Targeted at offshore wind farm operators requiring access to areas where scaffolding or cranes are impractical.
• Engineering & Consulting Engineering support for offshore projects including preparation of workflows, method statements, risk analyses, development of inspection concepts, and project support at sea as client representative, including Marine Warranty Surveyor approval documentation. Targeted at offshore wind farm developers and EPC contractors during installation, commissioning, and operations phases.

Broad incumbents

• Bilfinger: Large European industrial services provider with established offshore wind, energy, and process industry service lines; competes for the same operator inspection and maintenance contracts from a much larger resource base.
• Worley: Global engineering, procurement, and construction services provider with strong offshore wind and subsea engineering capability; overlaps on engineering consulting and integrity management scopes.
• Ramboll: International engineering, design, and consultancy firm with a large offshore wind practice covering foundation design, integrity management, and inspection support — directly competing for mh²' engineering and consulting work.
• SPIE: European multi-technical services group active in energy infrastructure including offshore wind maintenance, inspection, and modification — a broader portfolio player but overlapping on the same German operator clients.
• Wood Group: Global engineering and consulting firm with a dedicated offshore wind and marine operations practice; competes for engineering consulting, inspection, and integrity management scopes served by mh²' consulting arm.

Emerging players

• Stiesdal Offshore Technology: Danish offshore wind engineering and technology developer; overlaps with mh² on offshore structural engineering, foundation design, and technology-focused service work for the wind sector.

Direct peers

• Bladt Industries: Specialist manufacturer and service provider of large-scale offshore wind foundations, transition pieces, and substations; offers a directly overlapping portfolio of steel construction, welding, and offshore installation services.
• Smulders: Belgian/Dutch offshore steel construction company building foundations and substations for offshore wind; comparable in its steel-fabrication-led delivery model and European offshore wind customer base.
• Semco Maritime: Danish offshore service company delivering welding, construction, inspection, and modification work on offshore wind foundations and substations in Northern Europe — directly comparable service mix to mh² and even appears in mh²'s customer references.

Regional players

• EEW Special Pipe Constructions (EEW SPC): German-based manufacturer of monopiles and heavy steel pipe structures for offshore wind; comparable on heavy offshore steel fabrication, welding certifications, and German wind-sector customer base, though focused on new-build rather than service.
