Revenue model
- Sale of monopiles and transition pieces: Project-based manufacturing contracts for offshore wind foundations (WIND segment) — contract revenue recognised on production milestones; represents the majority of revenue. Q1 2026 Wind contribution was €55.0 million out of €63.8 million total contribution.
- Marshalling & Logistics services: Service revenue for storage, marshalling and logistics handling of foundations at Sif's Maasvlakte deep-sea quay. Q1 2026 Marshalling contribution was €0.2 million (scaled back to near-zero from Q3 2023 onward).
- Engineering services (KCI the engineers): Design engineering services for offshore foundations and energy market related projects, delivered through KCI the engineers B.V. acquired in March 2021. Q1 2025 engineering contribution €2.2 million.
- Offshore Steel Structures (OSS): Production of components (pin piles, jacket legs) for offshore steel structures / oil & gas jackets. Q1 2026 OSS contribution €5.5 million.
- Licensing of monopile production technology: License cooperation with GS Entec (Korea) signed July 2022 to transfer know-how and assist in converting Busan facility into monopile production site for Asian market.

Sif Holding product offering
Product offeringCore offering
Sif Holding N.V. manufactures large-diameter steel monopile foundations and transition pieces used to anchor offshore wind turbines into the seabed. The company operates two highly automated production facilities in Roermond and Maasvlakte 2 Rotterdam, with up to 500 Kton annual production capacity for monopiles up to Ø11.5 meters. It complements manufacturing with marshalling and logistics services at a 628-metre deep-sea quay, engineering services via subsidiary KCI the engineers, and licensing of monopile production technology to partners such as GS Entec in Korea.
Product overview
Sif Holding N.V. (Sif Group) is a total solutions provider for design engineering and manufacturing of offshore wind foundations, operating a portfolio built around a core set of structural products — Monopiles, Transition Pieces, TP-less Monopiles, and Pin Piles & Jacket Legs — complemented by supporting Marshalling & Logistics and Value Engineering services, as well as engineering services delivered through the acquired subsidiary KCI the Engineers. The portfolio is anchored by Sif's flagship Monopile product, which is described as the most common and cost-effective foundation for offshore wind turbines, while innovations such as Skybox extend the offering with slip-joint connection technology. Sif combines two highly automated production facilities (Roermond and Maasvlakte 2, Rotterdam) with technology leadership in rolling and welding heavy plate steel, and the products are delivered together via integrated marshalling and logistics services at its deep-sea quay.

Sif Holding partnerships and signals
Strategic signalPartnerships
Three partnerships are on record, tiered core and minor.
- GS Entec (Republic of Korea)coreStrategic licensing partnership signed July 2022 to develop monopile foundation production in the Asian region. Sif transferred know-how and trained GS Entec employees to convert their Busan facility into a monopile production site. License agreement finalised and kick-off implementation occurred in Q3 2022.
- Dillinger HüttecoreLong-term framework agreement signed with Dillinger Hütte (Germany) in Q3 2022 to secure future steel plate deliveries — a critical raw material for Sif's monopile production expansion to Ø11.5 metres and 500 Kton capacity.
- KCI the engineers B.V.minorKCI the engineers B.V. was acquired and consolidated as of 1 March 2021, strengthening Sif's in-house design engineering capacity for offshore wind foundations and energy market projects.

Sif Holding competitors and assessment
Company assessmentDirect peers
- EEW SPC: EEW Special Pipe Constructions is a German manufacturer of large-diameter welded steel pipes and one of the few direct competitors of Sif in European monopile production. Both serve offshore wind developers with heavy plate rolling and welding capabilities, making them the closest functional peer.
- Bladt Industries: Bladt Industries is a Danish manufacturer of monopiles, transition pieces and offshore substations. It competes head-to-head with Sif on European offshore wind foundation projects and shares a similar customer base of European offshore wind developers and EPC contractors.
- Steelwind Nordenham: Steelwind Nordenham (a subsidiary of Dillinger Hütte) is a German monopile manufacturer that competes directly with Sif. Sif sources its heavy steel plates from Dillinger, creating an unusual supplier-competitor dynamic typical of vertically integrated European monopile supply chains.
- Smulders: Smulders is a Belgian steel construction company producing jackets, transition pieces and substations for offshore wind. Smulders is also Sif's joint venture partner on the Baltyk project (100 transition pieces), illustrating the partially overlapping but complementary nature of their offshore wind offerings.
Broad incumbents
- Lamprell: Lamprell is a UAE/UK-based provider of fabrication, engineering and contracting services to the offshore wind and oil & gas industries. It is a broader incumbent that competes with Sif in offshore steel fabrication (jackets, substations) but operates across a wider portfolio including oil & gas and renewables EPC.
- Aker Solutions: Aker Solutions is a Norwegian provider of engineering, procurement and construction services for the energy industry, including offshore wind substructures and oil & gas platforms. Aker Solutions is both a customer of Sif (Yggdrasil, Valhall) and a broader incumbent in offshore steel fabrication.
- McDermott: McDermott is a global engineering, procurement, construction and installation company serving offshore energy projects. It overlaps with Sif in offshore structural steel fabrication and offshore wind construction but is a much larger and more diversified EPC incumbent.
Emerging players
- Doosan Enerbility: Doosan Enerbility is a Korean heavy industrial company developing offshore wind foundation manufacturing capacity in Korea. It represents the emerging Asian competitor cohort that could challenge Sif's licensing-led approach to the Korean market and other Asian geographies.
- CS Wind Offshore: CS Wind Offshore is a subsidiary of CS Wind, a Korean wind tower manufacturer expanding into offshore wind substructures including monopiles. It is an emerging player whose geographic focus in Asia intersects with Sif's Korean licensing strategy.
Others
- Dillinger Hütte: Dillinger Hütte is a German heavy steel plate producer and Sif's principal steel plate supplier under a long-term framework agreement. As parent of Steelwind Nordenham it is also a partial competitor, making it a critical adjacent ecosystem participant in Sif's supply chain.
