What ISC Rådgivende Ingeniører does

ISC Rådgivende Ingeniører A/S (CVR 26340713) is a privately held, family-owned Danish engineering consulting firm founded in 1967 and headquartered at Hesseløgade 16, 2100 København Ø. The firm operates through seven Danish offices (Copenhagen Ø, Copenhagen Øster Allé, Aalborg, Aarhus, Esbjerg, Kalundborg, Kolding) and employs 101-250 engineers across five service lines: Renewable Energy (the flagship), Oil & Gas, Buildings, Infrastructure, and Industry. Its renewable-energy practice is built on a 20+ year offshore-wind track record that began with the world's first offshore substation (Nysted Havvindmøllepark, 2003) and now spans detailed designs for more than 50 offshore substations across Europe, Asia, and the United States — including Hornsea 2 (1,320 MW, the world's largest HVAC offshore substation).

The company's core technology offering covers the full design lifecycle of offshore wind infrastructure: HVAC and HVDC substations, WTG foundations (monopile, jacket, gravity-based), floating substations, and four conceptual architectures for offshore hydrogen production (Power-to-X). Multidisciplinary in-house engineering covers structural, electrical, process, fire safety, geotechnical, HVAC, mechanical, and piping disciplines from feasibility through commissioning. Non-renewable practice areas cover oil & gas topsides and modifications, buildings with DGNB sustainability certification, complex infrastructure (bridges, ports, metro), and industrial process plants — supported by ISO 9001/14001/45001 certifications through May 2028 (DNV) and familiarity with regulatory frameworks including Germany's BSH.

The business model is project-based, quote-driven engineering consulting sold directly to enterprise clients — primarily offshore wind farm owners and developers (Ørsted, RWE, Vattenfall, Dominion Energy, EDP Renewables, Vineyard Wind, Parkwind, PGE) and EPCI contractors (Bladt Industries, Semco Maritime), plus selected government (Næstved Kommune, Metroselskabet) and industrial clients. ISC engages on long-term, multi-project programs (e.g., Hornsea 2, Coastal Virginia, Vineyard, Sandbank, Nordsee Ost, Baltica 2, Hai Long) via direct enterprise field sales. Pricing is non-public and negotiated per project. There is no public funding, M&A, or revenue disclosure.

Core offering

ISC Rådgivende Ingeniører A/S is a Danish engineering consulting firm providing multidisciplinary design and engineering services across renewable energy, oil & gas, buildings, infrastructure, and industry. Its flagship offering is detailed engineering design for offshore wind projects, including HVAC and HVDC substations, WTG foundations, floating substations, and offshore hydrogen production concepts. Services span the full project lifecycle from feasibility studies and concept design through detailed design, fabrication, installation, commissioning, and follow-up supervision.

Product overview

ISC Rådgivende Ingeniører is an engineering consulting firm specializing in five core areas: Renewable Energy, Oil & Gas, Buildings, Infrastructure, and Industry. The Renewable Energy division is the flagship offering, providing specialized services including HVAC Substations, HVDC Substations, Hydrogen Production (Power-to-X), WTG Foundations, and Floating Substations. The company has been a pioneer in offshore wind since 2003, when it designed the world's first offshore substation, and has delivered detailed designs for over 50 substations globally. Supporting these core offshore wind services are specialized engineering disciplines covering electrical, process, fire & safety, structural, geotechnical, HVAC, mechanical, and piping design. The remaining four divisions (Oil & Gas, Buildings, Infrastructure, Industry) provide traditional engineering consulting services spanning the full project lifecycle from feasibility studies through detailed design and commissioning.
