RINA is a private, multinational company headquartered in Genoa, Italy. It was founded in 1861 under the name Registro Italiano Navale (Italian Naval Register).

In 1999, following the enforcement of a 1994 European Council directive regarding the inspection, survey and certification of ships^[6] that liberalized the ship classification market, the Registro Italiano Navale transferred all operational activities to RINA S.p.A.,^[7] making it the sole, and later, majority shareholder.^[8]

Until 1999, RINA worked almost exclusively as a ship classification company. It has since included operations in the following sectors: Energy and Mobility, Marine, Certification, Industry and Real Estate and Infrastructure. The company has also expanded its services in the fields of testing, inspection and certification and engineering consultancy.^[9]

The group is headed by RINA S.p.A., which acts as the holding company and no longer carries out operational activities, but provides the group with administrative, organisational and financial services. As parent company, RINA S.p.A. also controls the two main sub-holdings RINA Services S.p.A. and RINA Consulting S.p.A.^[17]

Until 2023 the shareholders of RINA S.p.A. and therefore of the whole Group, are Registro Italiano Navale, with a large majority share (70%), Naus S.p.A. (27%) and RINA management (3%).^[18]

On June 1, 2002, Ugo Salerno was appointed Chief Executive Officer of RINA; since 2012, he has also held the position of Chairman.^[19]

On 13 December 2023, Fondo Italiano d'Investimento SGR officially entered into the shareholder structure of RINA S.p.A.^[20] The new share distribution gives Registro Italiano Navale a majority stake, 33% to Fondo Italiano d'Investimento and other co-investors led by it, and 3,5% to RINA's management.

Concurrently, on the same day, the Board of Directors of RINA S.p.A. appointed Carlo Luzzatto as the CEO and General Manager of the company, while Ugo Salerno remains in his role as the Executive Chairman.^[21]

The first office outside of Italy was opened in Shanghai in 1885.^[22] Today, it has a network of over 200 offices in 70 countries worldwide with a workforce of 5,300 people. Its head office is in Genoa.

RINA provides quality assurance and certification for ship's components and accessories, including life-saving appliances, marine pollution prevention, fire protection, navigation, radio communication equipment, deck gear, cables, rodes, and anchors.^[23] It also provides engineering consultancy services through the RINA Consulting S.p.A. and its subsidiaries.

RINA is one of the founding members of IACS and actively participates in technical, research and rule-making groups in different institutional contexts at national and international level.

In December 1999 the tanker MV Erika sank off the coast of Brittany, causing a major oil spill. RINA was the certification society responsible for issuing all the safety certificates for Erika.^[24] The case came to trial in 2007 and Total, which chartered the oil tanker, was eventually found guilty and ordered to pay a fine of 375,000 € and a compensation to the civil parties of 200 M €.^[24][25]

In December 2012 the garment factory Ali Enterprises in Karachi burned down causing 289 victims.^[26] The Company was certified in the weeks before this incident by RINA with a SA8000 certificate.^[27]
