What Neptun Werft does

Neptun Werft is a German shipyard headquartered in Rostock-Warnemünde and operating as a wholly-owned subsidiary of the MEYER WERFT Group since 1997. The yard builds river cruise ships, ferries, and gas tankers, and produces fully equipped floating engine room units (FERUs) — modules up to 140m long, 16m high, and 46m wide — that are towed to the group's Papenburg facility for integration into ocean cruise ships. Its core technology stack combines modular block construction ("Lego principle"), 3D CAD/virtual construction, and Industry 4.0-enabled digital process management, supported by a 150-metre lowering device and 13,000 m² of production halls. The customer base is concentrated among major cruise and river-cruise operators — notably Viking Holdings (a 22-ship committed orderbook through 2028) and AIDA Cruises (LNG-powered engine room modules) — with all contracts negotiated directly on a multi-year, build-to-order basis.

Beyond cruise, Neptun Werft has, through its joint ventures Neptun Smulders Offshore Renewables (NSORe) and Neptun Smulders Engineering with Belgium's Smulders (an Eiffage subsidiary), entered the European offshore energy infrastructure market. In 2026 the NSORe–Siemens Energy consortium was awarded the turnkey North Sea Connector 2 HVDC converter contract by German TSO 50Hertz, with commissioning by end-2034 and a combined ~€2.5 billion potential across Connector 1 and 2. The yard employs approximately 600–650 people plus 30–35 apprentices and is one of the largest employers in the Mecklenburg-Western Pomerania region.

The business model is project-based B2B shipbuilding with no consumer-facing distribution, no public pricing, and revenue recognised upon delivery of completed vessels or modules. Sales cycles run multiple years from contract to delivery, and the company is currently pursuing parallel growth tracks: deepening the river-cruise orderbook with Viking, scaling FERU output to its four-units-per-year capacity, and bidding additional European HVDC converter tenders to capture energy-transition infrastructure spend — supported by a possible €300 million German federal loan guarantee aimed at reducing Chinese supply dominance.

Revenue model

1. Newbuild River Cruise Ships: Design and construction of new river cruise ships to customer order, including vessels for Viking Holdings. Revenue is project-based, earned upon delivery of completed vessels. Long production cycles with significant upfront engineering and fabrication costs.
2. Floating Engine Room Units (FERUs): Construction of fully equipped floating engine room modules for cruise ships built at MEYER WERFT in Papenburg. Units are transported by tugboat to Papenburg for integration. Revenue recognized upon module delivery and handover.
3. Ferries and Gas Tankers: Construction of ferries and gas tankers as part of the production programme. Project-based revenue model with custom-build-to-order arrangements.
4. Offshore Converter Platforms (via NSORe JV): Through Neptun Smulders Offshore Renewables (NSORe) joint venture, construction of offshore and onshore HVDC converter systems for grid connection projects (e.g., North Sea Connector 2, part of NordOstLink). Turnkey contracts for 2GW converter platforms. Combined potential contract value of approximately €2.5 billion for both connectors.
