About RINA
- RINA S.p.A. was stablished in 1861 and is a founding member of IACS (International Association of Classification Societies). RINA’s headquarters are in Genova, Italy but the company has over 200 offices in 70 countries. Marine business represents about 27% of the company’s operating revenues. It operates on behalf of 122 flag authorities, and it is one of the top-ranking marine classification societies in the world. In the last three years, RINA’s fleet has grown at rates of over 15% thanks to the classification of existing ships and the delivery of new buildings. In addition to the provision of classification and statutory certification, it delivers value added services to the shipping industry. Today, RINA provides tailored advisory services for shipyards and shipowners, particularly in complex areas relating to sustainability, environmental regulations and digital technologies
- Decarbonisation is the driving force of the shipping sector for years to come, and RINA plays a proactive role towards achieving a sustainable future. Innovation is the main driver of RINA’s evolution, and it is key to ensuring continued success. Through research and innovation RINA builds a knowledge base, exploring new market opportunities and anticipating new trends, to offer innovative and high-level services. RINA is among the most active industrial players in European research and innovation programs.
- In NH3craft project, RINA contributes to all the engineering design, manufacturing, risk assessment and testing activities needed for regulatory compliance, both for the demonstrator, the auxiliary systems and the desktop studies on five selected ship types.
Meet the Experts Driving NH3CRAFT Forward
- Alessandro Maccari:

- Alessandro Maccari has an M.Sc. in Naval Architecture and Marine Engineering, currently Director of Marine Research and Development at RINA Services S.p.A. – developed multidisciplinary competences in ship design, shipbuilding, and strategic innovation activities applied to more than 60 passenger ships. Adviser of the Italian Flag Administration at the International Maritime Organization (IMO) since 1994, he actively contributes to the development of the regulatory framework on marine environment protection and on ship safety in a vast collaborative international network.
- Alessandro Maccari has been involved both in managerial and technical activities within the NH3craft project. More specifically he has been involved in leading and coordinating the activities related with the specification of the ammonia containment system demonstrator’s requirements and establishing the boundaries and data required for the desktop studies (WP2). In addition, he has a significant role in updating the consortium regarding the upcoming rules and regulations deriving by the IMO.
- Nikoletta Trivyza

Nikoletta Trivyza has been part of the Marine Research and Development department of RINA for the last three years. She is a graduate of the School of Mechanical Engineering at the National Technical University of Athens (NTUA) and holds a PhD degree in decision support for sustainable ship energy systems from the University of Strathclyde. She is now actively involved in various research projects related with the decarbonisation of the shipping sector such as NH3CRAFT, LH2CRAFT and SAFeCRAFT research projects. In parallel, she is engaged in preparing and submitting funding proposals for new research projects in the fields of shipping and alternative fuels and technologies.

How RINA is Powering NH3CRAFT’s Success
- [WP2 Demonstration Implementation plan and evaluation criteria] – RINA is the Work Package leader and has contributed to the following:
- RINA was deeply involved in the specification of the ammonia containment system demonstrator’s requirements.
- In addition, RINA played a leading role on establishing the boundaries and data required for the desktop studies, including auxiliary systems where appropriate, bunkering arrangements, implementation requirements of project solutions on new-buildings and tank configurations (on-deck or hull-integrated storage).
- RINA also led the concept design of the demonstrator.
- [WP3 Engineering design process for the tank storage systems] – RINA contributed throughout the engineering design and reviewed relevant deliverables to ensure compliance with the regulations.
- [WP4 Engineering design process for the auxiliary systems] – – RINA contributed throughout the engineering design and reviewed relevant deliverables to ensure compliance with the regulations.
- [WP6 assembly, installation and functionality testing of system] – RINA looked after all the relevant testing activities to ensure compliance with the regulations.
- [WP7 Safety & Risk assessment] – RINA was deeply involved with the safety risk assessment of the demonstrator. This was significant for the risk mitigation and verification of the detailed design. In addition, RINA provided continuous updates to the consortium with the relevant upcoming regulatory requirements.
- [WP11 Dissemination, Exploitation and communication] – RINA has contributed in various ways in the dissemination and communication material providing input in various ways, such as the website, the poster, the banner and relevant posts made through the communication platforms. Finally, RINA obtained an invitation for the consortium to present the NH3CRAFT Ammonia dispersion study to the IACS Safe Decarbonisation Panel Members during their 2024 Spring meeting.
