Company profile
Engineer, fabricate and install complex energy infrastructure
Rosetti Marino is a Ravenna-based engineering group that grew from a one-worker mechanical workshop founded in 1925 into an international contractor. It combines in-house engineering, procurement, fabrication yards, offshore installation and technical services for conventional energy, offshore wind, carbon capture and energy-storage infrastructure, supported by specialist companies and operating bases outside Italy.
Products and services
Take an offshore structure from early design to installation
Rosetti Marino delivers topsides, jackets, living quarters, compression and utility modules, subsea structures and brownfield revamps. Its scope can run from FEED and detailed engineering through procurement, fabrication, commissioning, offshore installation, operations and maintenance, joining office engineering with its own construction yards.

Energy-transition projects
Build offshore wind foundations, hydrogen storage and carbon-capture platforms
For Nordsee II and Gode Wind 4, the group delivered a 60-metre jacket and a 30-metre transition piece. The Baseload Power Hub combines batteries, an electrolyser and a fuel cell inside an offshore wind farm. A Liverpool Bay project extends the portfolio to four structures for carbon capture and storage.
- Nordsee II and Gode Wind 4 Offshore-wind jacket and transition-piece delivery
- Baseload Power Hub Battery, electrolyser and fuel-cell energy storage
- Liverpool Bay CCS Four structures for a North Sea carbon-storage system
- Technology projects Electrified syngas reactors and pilot-scale development
Projects and geography
Load out in Ravenna, then deliver from the North Sea to Tierra del Fuego
Tolmount paired a 5,000-tonne topside with a 75-metre jacket for the North Sea. Ravenna's FSRU terminal required an EPCIC receiving platform and mooring structures, while Fenix placed an 86-metre wellhead jacket off Tierra del Fuego. Owned and partner yards extend fabrication into Kazakhstan.
- Tolmount platform North Sea topside, jacket and EPCIC delivery
- Ravenna FSRU terminal Receiving platform, gangways, moorings and piles
- Fenix platform An offshore wellhead platform for Tierra del Fuego
- Worldwide presence Group companies, yards and delivery countries

Heritage and operating model
Turn a blacksmith workshop into a network of engineering specialists
Marino Rosetti began with one worker on 1 April 1925. The Piomboni yard later opened the offshore-construction market; Fores Engineering added automation and electro-instrumental systems, while Basis and Tecon deepened multidisciplinary design. The same timeline records work on the Costa Concordia recovery and Carlo Magno's role refloating Ever Given.
