ICN’s mega operation to transport sections of the Tonelero submarine

ICN carries out mega operation to transport sections of the Tonelero submarine. ICN, formed by the OEC and the French Naval Group, promoted a real war operation to transport three sections of the Tonelero submarine, the third in the series of four Riachuelo class submarines being built through Prosub for the Brazilian Navy in Itaguaí (RJ). The S2B/S3/S4 sections already joined compose the front part of the Tonelero submarine that shelters the crew’s accommodations, vessel control room and the torpedo tubes.

Built with 100% Brazilian manpower by ICN, in the Manufacturing Unit of Metallic Structures, in Itaguaí, the sections represent a great landmark for the naval industry and the country’s defense sector, as they materialize the advance of engineering and the training of new skills for thousands of Brazilian workers who successfully received the transfer of French technology, allowing not only to manufacture submarines, but also the possibility to develop a complex 100% national naval projects.

It took approximately nine hours on a 4.5-kilometer route, from the factory to the shipyard, involving the work of several operational teams, from ICN technicians to Federal Highway Police support, Navy scouts, Military Police, Itaguaí City Hall, and other partners.

To complete the transfer of the Prosub’s third submarine, the last section, which houses the rudders, propeller and electric propulsion engine (MEP),  will be transferred on October 29th. The full integration of the S42 Tonelero will take place on December 11th this year, at the same launching ceremony for the second submarine of the program, the S41 Humaitá, in a presidential event at the shipyard, and it will be broadcasted online on ICN’s and the Navy’s social networks.

Itaguaí Construções Navais – ICN

Created to manufacture five submarines for Prosub, four conventional and one with nuclear propulsion, the taguaí Construção Navais (ICN) has become a reference in highly complex projects in the naval industry, becoming a multi-product company, capable of building multiple vessels on demand from the Brazilian Navy, such as corvettes, Tamandaré class ships, arctic ships, submarines, maintenance and/or upgrade of submarines and other naval surface systems.
