The company Rosetti Marino was founded in Ravenna between the two World Wars. Established by Marino Rosetti on 1st April 1925 as a “mechanical and blacksmith workshop”, it started with a single worker and took over the former Officina Meccanica Rosetti Menotti, founded by his father.

In the 1930s, Marino Rosetti led the workshop’s growth with vision and practicality.
He left behind old markets to explore new ones, expanded both staff and facilities, and built lasting relationships based on trust and integrity.
Through his steady commitment, the company began to take shape as a stronger and more established enterprise.

Over the years, the company expanded and, from the 1940s onwards, began specialising in boiler-making and ship repair, relying on a mechanical workshop and a yard area located within the Port of Ravenna.

The first major turning point occurred in the 1950s, when Marino Rosetti recognized the expansion potential that could arise from a partnership with Serafino Ferruzzi, who then led Italy’s most important grain import and export group. This initiative ushered in a period of significant transformation.
Starting as a simple ironworks and metalworks company,  Rosetti Marino entered the ship conversion market.

In the summer of 1960, AGIP – Azienda Generale Italiana Petroli, under the leadership of Enrico Mattei, discovered the first offshore natural gas field off the coast of Punta Marina at a depth of 1,500 meters.
Named Ravenna Mare III, it was the first offshore productive well in Europe and the Mediterranean. Drilling in the North Sea would only begin ten years later.
During this period, Ravenna became an integrated industrial hub, where alongside the AGIP district, the petrochemical complex ANIC (Azienda Nazionale Idrogenazione Combustibili), founded in 1953 and producing rubber and fertilizers, also developed. Gianfranco Magnani, son-in-law of Marino Rosetti and head of the company for several years, together with his right-hand man Medardo Ranieri, recognized the epochal transformation taking place in Ravenna at the time and foresaw the enormous development potential of the offshore energy business.
Rosetti Marino entered the offshore sector with the construction of metal structures (jackets and decks) for the newly established steel islands, giving its significant contribution to the industrial development that Enrico Mattei had envisioned for Ravenna.

The headquarters moved from the city center to the current site in Via Trieste, where administrative offices and a large workshop for prefabrication were established.
The construction of offshore structures was added to the production of pressure vessels and continued throughout the 1970s, following AGIP’s exploration activities in the Adriatic Sea. These were large-scale structures, but still monodisciplinary in nature — that is, “bare,” without any installed systems.

Between 1975 and 1980, Rosetti Marino acquired, in several stages, the large Piomboni yard in Marina di Ravenna – a key asset that enabled the company to fully enter the offshore construction sector.

The offshore market began demanding multidisciplinary products.
Gianfranco Magnani, always supported by Medardo Ranieri, enhanced its organization and shifted towards project- based operations, structuring its departments around contract execution.
Iron alone was no longer enough: the “bare” structures now had to be equipped with the systems required for oil or gas extraction and transport, capable of generating their own electrical power, and fitted with accommodation modules for the personnel working at sea.
This period also saw the establishment of RosBos, a consortium company between Rosetti Marino and Bouygues Offshore, which brought to Ravenna several complex projects for major oil companies.
Thanks to RosBos, Rosetti Marino began working with international clients, and the Piomboni Yard became a benchmark for offshore plant engineering throughout the Mediterranean and West Africa.

Tecon Srl was founded by Tullio Balestra and Dario Varisco, two engineers specialized in structural design and in providing support for the construction and installation of offshore structures.
It was an encounter between highly skilled professionals — but also between gentlemen — that over time gave rise to an increasingly profound synergy, built on mutual respect, esteem, a shared passion for their work, and common values and goals.

Fores Engineering Srl was established in Forlì as a subsidiary company specialising in the provision of engineering and electro-instrumental services.
With great insight and commercial acumen, Medardo Ranieri immediately seized the opportunity to bring together within this new entrepreneurial venture specialized expertise and disciplines in which Rosetti Marino, historically a mechanical construction company, still had limited experience.
In the years to come, Fores Engineering would expand its business by entering the market for the design and construction of automation and control systems, as well as skid and package units and technical assistance services.

Rosetti Marino was awarded the turnkey contract for the Daria B platform, destined for the Adriatic Sea. It was the company’s first EPC (Engineering, Procurement, Construction) contract.

The company resumed its historic role as a shipbuilder with the acquisition of a 50% stake in Cantieri Ravenna, located on Via XIII Marzo 1987.
The company owned a large equipped area and a dry dock at Porto San Vitale.
Here, a long series of tugboats were launched, including the Braveheart, the first Azimuth Stern Drive Tug with a bollard pull of 100 tonnes.

The jacket for Ivana A, a platform destined for the Croatian offshore sector, was launched. This was the first offshore structure built by the company outside the Marina di Ravenna yard — a significant first step in Rosetti Marino’s growth beyond national borders.

The shipbuilding company Cantieri Ravenna, was incorporated into Rosetti Marino, through the transfer of the shipbuilding division, which also included ownership of the San Vitale Shipyard on Via XIII Marzo.
The newly established Naval Division expanded its business from ocean-going tugs to platform support vessels, specializing in the construction of powerful Platform Supply Vessels (PSVs) serving platforms in the North Sea, the Gulf of Mexico, the Mediterranean, and the West African coasts.

These were the years of international expansion for Rosetti Marino, during which the company intensified its search for new geographical areas, products, and clients.
The need to “go abroad” arose from the challenges of transporting extremely large structures, such as platforms, over long distances, as well as from the local content requirements imposed by foreign countries where these structures were destined.
The 2000s marked a period of international expansion for Rosetti Marino. It was during this time that the Kashagan field was discovered – the largest offshore hydrocarbon deposit in the world – located in Kazakhstan, in the north-eastern waters of the Caspian Sea.
Rosetti Marino became involved in this major project by securing the contract for the construction of the Karligash floating living quarters: an accommodation module for 180 people, equipped with air-conditioned cabins, offices, a laundry, gym, recreation rooms, kitchens, and a canteen.

Rosetti Marino began its first operational activities along the shores of the Caspian Sea, in the Russian Federation, at a shipyard on the Volga River near the city of Astrakhan. Between 2005 and 2010, the Ravenna-based company built a series of process modules which, due to their considerable size, could not be transported along the Volga-Don Canal.

Production began on a new type of vessel: Anchor Handling Tug Supply Vessels (AHTS), including the Carlo Magno, which in 2021 helped refloat the Ever Given ship that had run aground in the Suez Canal.

KCOI – Kazakhstan Caspian Offshore Industries LLP – was established. From that moment on, KCOI progressively structured itself to manage major offshore and onshore projects with its own personnel, as the Rosetti Group company operating in Kazakhstan.

Rosetti Marino succeeded in securing a contract from Total UK for the EPCI (Engineering, Procurement, Construction, Installation) of the West Franklin
and Elgin B gas platforms, destined for the Scottish North Sea.
The company had to face two major technical challenges: the record levels of pressure and temperature in the reservoir, and the particular complexity of designing and constructing the gas treatment facilities.
Thanks to the excellent design work carried out first by Basis Engineering and Tecon, and later the construction at the Piomboni yard, the project was completed successfully, earning the full satisfaction of the Client.
The West Franklin and Elgin B project remains today a global benchmark for fields of such complexity.

On January 13th, 2012, the Costa Concordia cruise ship ran aground after striking rocks near the port of the Island of Giglio. The recovery tender was awarded to a consortium led by Titan (USA) and Micoperi (Ravenna), which immediately brought in Tecon for its expertise in complex marine operations.
The mission — to recover a 45,000-tonne, 300-meter-long ship intact — had never been attempted before. Within a month, Tecon presented a feasibility study to rotate the vessel, bring it upright, and refloat it with minimal environmental impact, using equipment that could be fully removed at the end of operations. This plan earned Tecon the executive design contract.
Rosetti Marino handled the construction of two underwater platforms supporting the ship’s rotation, assembling 2,200 tonnes of steel in under six months.
In September 2013, the Costa Concordia was successfully brought upright in just 19 hours, and in July 2014, it made its final journey to the port of Genoa.

Rosetti Marino entered the Technical Service business with the Goliat FPSO – Floating Production Storage and Offloading – project, located near the Arctic Circle.

Oscar Guerra was appointed Chief Executive Officer. He believed the company was ready to further expand its geographical footprint and to pursue a diversification strategy aimed at reducing its dependence on the Oil & Gas sector. The target areas identified were Nigeria and the Arabian Gulf.
RPL – Rosetti Pivot Ltd – was established in Lagos, Nigeria, as a joint venture between Rosetti Marino and a prominent local shareholder. RPL became the key vehicle for entering a promising yet complex market such as Nigeria, focusing on the revamping of offshore installations that had become obsolete and required modernization to boost hydrocarbon production in Africa’s most populous country, where many offshore facilities had already exceeded 20 years of service and were nearing the end of their lifecycle.

The first platform ever made in Qatar was built by Rosetti Marino.
Qatar Gas – a global leader in liquefied natural gas – awarded Rosetti a hybrid greenfield/brownfield project involving the construction of a new accommodation module connected to the existing living quarters.
Rosetti Marino’s execution strategy initially planned for the new structure to be built in the United Arab Emirates. However, just a few weeks after the contract signing, an unexpected crisis erupted between Qatar and Saudi Arabia, soon joined by the UAE. The so-called “Qatar blockade” forced Rosetti Marino to completely rethink its plans.
At the client’s request, the company had to organize the construction of the platform directly in Qatar, a country where such a project had never been carried out before.

RSY – Rosetti Superyachts was established to enter in the market as a builder of elegant and exceptionally reliable yachts in response to the price crisis caused by the trade war between the United States and Saudi Arabia, which had a significant impact on the offshore business.

Rosetti Marino was awarded a four-year contract by Mobil Producing Nigeria for a major offshore revamping project.
The Idoho platform was the first project managed by Rosetti Marino’s Nigerian subsidiary, followed by many others carried out in an ethical and sustainable manner, always in full respect of the host country.

RAS – Rosetti Ali & Sons LLC – was established in Abu Dhabi as a company under Emirati law, consolidating Rosetti Marino’s presence in the Arabian Gulf, a geographical area that had already been a focus of attention a few years earlier. Based in Abu Dhabi, the newly formed company represents a strategic partnership with a major local construction contractor, capable of delivering high-level services in the construction of offshore structures.

Alongside the traditional Oil & Gas sector, plans were made to enter the Renewables and Carbon Neutrality market, positioning itself as a leading contractor in the opportunities arising from the Energy Transition: offshore wind, carbon capture–utilization–and–storage (CCUS), decarbonization, and biomethane.
This marked the creation of the company’s new Energy Division.
Six offshore wind projects were acquired for France, Germany, and the Netherlands.
Five of these involved the construction of offshore electrical substation structures, while the sixth concerned the development of the world’s first platform capable of producing green hydrogen from offshore wind energy.

Rosetti Marino acquired 60% of Green Methane Srl, thereby expanding its technological expertise in the field of CO₂ capture, in line with its commitment to Renewables & Carbon Neutrality.

First contract for the production of rubber derived from plant-based hydrocarbons, replacing those from fossil sources.

Rosetti was awarded the project for the construction of a large module for the decarbonization of an offshore plant, enabling the recovery and utilization of natural gas

KCOI was awarded the contract for the construction of the first hybrid renewable–gas power plant in Kazakhstan, one of the first of its kind in the world.

The Ravenna LNG terminal was designed, built, and installed in record time for a project of this scale

Two major projects were delivered in the field of Renewables and Carbon Neutrality: a structure integrating an offshore wind farm off the German coast in the North Sea and a pilot-scale offshore energy storage system that produces green hydrogen and stores it in batteries to provide stable power from a Dutch wind farm.

The Technological Innovation Department has successfully completed important projects co-funded by the Emilia-Romagna Region. In collaboration with the Politecnico di Milano, we carried out experimental validation of an innovative technology for producing syngas from green hydrogen and CO₂ — a crucial step toward the production of synthetic methanol (e-MeOH).
Starting in 2023, the construction of a pilot plant featuring a 25 kW reactor and its related system to test the “e-RWGS” technology on an industrial scale was completed.
The project also included the installation of a new 864 kWp photovoltaic system, expected to generate over 1,031,100 kWh of renewable energy per year.

The company Rosetti Marino was founded in Ravenna between the two World Wars. Established by Marino Rosetti on 1st April 1925 as a “mechanical and blacksmith workshop”, it started with a single worker and took over the former Officina Meccanica Rosetti Menotti, founded by his father.
