The objectives of these underwater operations are namely in the Atlantic Ocean off the Brazilian coast: the yet to be constructed oil rigs for the oil fields recently found in Santos, Campos and Espirito Santo.
The construction of the whole fleet, which includes 20 conventional submarines, is due to be completed by the year 2047.
The planned nuclear submarine however remains the most ambitious projects: with six thousand tons and 96.6 meters in length, the construction will take up to eleven years. It will be driven by a nuclear reactor developed at the Marine Research Centre Aramar. A land prototype for the entire drive of the nuclear submarine boat is currently under construction -– in a size ratio of 1:1 to the original drive to be built later. Once this test phase has concluded, the entire submarine will be completely assembled for testing purposes in a multiple-story building.
THE SOLUTION For the drive test rig, VULKAN has delivered in cooperation with the subsidiaries VULKAN do Brasil and VULKAN Italia a flexible coupling RATO S 731T and the elastic mounts.
"For decades, VULKAN has successfully participated worldwide in many marine projects already via the French DCNS (a world leader in naval defence and innovator in the energy sector). We have a very good reputation because of many submarine projects in Europe, Asia and Australia", says Eric Boon, responsible sales team and driving force behind the submarine project.

THE BENEFITS Not only the long-standing successful cooperation of the Brazilian VULKAN subsidiary with the officials at the Brazilian Navy, but also another current project predestine VULKAN to be the preferred coupling supplier: In 2008, Brazil ordered four submarines of the Scorpène class as part of its armament programme, which will be supplied from 2017. For the diesel-electric main propulsion of the first submarine of this class, the S40 "Riachuelo", VULKAN has already delivered an elastomeric coupling RATO S 48. A further one for the second of the four submarines is currently in production.
