What Offshore Industry Service does
OIS-Conbit is an integrated offshore services company formed in April 2026 when Conbit acquired OIS Offshore Industrie Service GmbH and ISC, combining three specialized offshore service firms. The company delivers electrical, hydraulic, crane, and lifting services for offshore wind, maritime and port, oil & gas, and selected industrial clients across the Baltic and North Sea regions from hubs in Rostock and Bockhorn, Germany.
The core technical platform spans four integrated disciplines: MV, HV, and HVAC electrical services for wind turbines and substations; hydraulic support for offshore wind components, maritime crane systems, and jack-up installation units; crane services covering the full asset lifecycle including maintenance and statutory inspections (e.g., DGUV V3); and engineering-led lifting services combined with IRATA-certified rope access. An equipment supply line provides new, refurbished, and rental cranes, heavy load-handling tools, special lift booms, and rigging components. A condition monitoring service line offers fleet management insights, maintenance forecasting, and deck equipment optimization. Notable engagements include a DGUV V3 inspection campaign across 80 turbines at Meerwind Sud and Ost, an ICCP system supply and commissioning award at the SylWin Alpha converter station (executed with Bluestream and Deepwater), and interim electrical services at the He Dreiht offshore wind farm.
The business model is project-based enterprise services revenue. There is no public pricing; all engagements are quoted per project via direct consultation. Customers include major European energy and infrastructure operators — Tennet, Vattenfall, RWE, ENBW, Otary, Equans, Hellenic Cables — alongside named wind farms and offshore platforms. Go-to-market is engineering-led direct field sales under the Commercial Director, supported by content marketing (whitepapers, case studies), industry event presence (e.g., COS Lifting Incident Sharing Summit 2025), and a localized digital presence across seven European languages. The company employs 11–50 people and operates as a privately held German GmbH under Conbit ownership.

Offshore Industry Service competitors and assessment
Company assessmentDirect peers
- Osbit: Osbit designs and supplies specialized offshore lifting and handling equipment for the offshore wind and oil & gas sectors. Its focus on engineered offshore lifting solutions overlaps directly with OIS-Conbit's lifting and crane services practice.
- DeepOcean: DeepOcean is a subsea IMR and offshore services contractor serving oil & gas and offshore wind clients across the North Sea. Its survey, IMR, and installation services for offshore assets make it directly comparable to OIS-Conbit's integrated offshore service offering.
- Mammoet: Mammoet is a global heavy lifting and transport specialist serving offshore wind, oil & gas, and industrial customers. Its engineered heavy lifting services and crane rental capabilities mirror OIS-Conbit's lifting services and temporary crane offerings.
- Acteon Group: Acteon is a UK-headquartered group of offshore energy services businesses offering integrated subsea, foundation, mooring, and survey services. Like OIS-Conbit, it pursues a multi-discipline offshore services model targeting wind, oil & gas, and maritime customers, making it a closely aligned structural peer.
Broad incumbents
- Worley: Worley is a global energy, chemicals, and resources project services company with deep offshore engineering, construction, and maintenance capabilities. It is comparable as a broader incumbent whose energy asset services compete for the same European offshore wind and oil & gas maintenance budgets.
- Subsea7: Subsea7 is a global subsea engineering, construction, and services contractor serving the offshore energy industry. It competes for offshore wind installation and oil & gas offshore work that touches OIS-Conbit's addressable market, but at materially larger scale.
- Huisman: Huisman is a Netherlands-based designer and manufacturer of heavy construction equipment including offshore cranes, winches, and pipelay towers. It is comparable to OIS-Conbit's crane supply activity but operates at a much larger scale and broader scope.
Regional players
- Føn Energy Services: Føn Energy Services is a Norway-based provider of technical and operational services to the offshore wind industry. Its multi-discipline offshore wind service model is comparable to OIS-Conbit's, though it is primarily focused on the Norwegian continental shelf.
- Stiesdal Offshore Technology: Stiesdal Offshore Technology is a Danish offshore wind technology and engineering firm focused on floating and fixed-bottom wind foundations. Its engineering and offshore wind focus overlaps with OIS-Conbit's offshore wind technical services, though it is geographically anchored in Denmark.
Emerging players
- Verlume: Verlume is an emerging subsea power and energy storage specialist serving offshore wind, oil & gas, and aquaculture. It represents an emerging capability adjacent to OIS-Conbit's electrical services for offshore wind assets, though focused on power delivery rather than broader maintenance.
