Apart from the professional experience in Brazilian Navyand submarines for over 30 years.


LOGSUB throughout its history participated or developed with its partner companies several projects. Among them we can highlight the following:

Tupi Class Submarine Rescue Bell Coupling System

The Tupi Class Submarine Rescue Bell Coupling System is composed of a lug installed on the forward hatch of the submarine not soldered, but adapted to a stainless steel cross stuck to pre-existing screws results in the hatch. This device has met an old need of the Submarine Force and avoided the total replacement of the hatches by others with this eyelet, thus bringing a very low cost solution for the Submarine Force of the Navy of Brazil.

Brazilian Navy Ship Repairs

In partnership with the Survey Engenharia Company LOGSUB managed all BN Ship repairs at the Naval Base in Rio de Janeiro from 2010 to 2014, in the boiler, structural and network services in general. Some of the ships are NSS Felinto Perry, 04 PMG from NE Brazil, NE CisneBranco, NDD Rio de Janeiro, NT Marajó, Niterói Class Frigates and Inhauma Class Corvettes, Patrol and Hydrographic Ships.


In 2010, LOGSUB, in partnership with Babcock Integrated Technoloy (UK), developed and finalized a proposal for the adaptation and installation of a transfer station at the NT Marajó stern. This project had a high nationalization index with the manufacture of the entire structural part, nets, pumps and winches in Brazil that would be manufactured at BNRJ facilities at the time.

SubmarineRescue System

LOGSUB, in partnership with JFD (UK) presented to the Brazilian Navy (BN) a proposal to provide a modular and airborne Rescue System, a common high nationalization and manufacturing index in Brazil, which can be quickly deployed and installed on any opportunity vessel in any national port.

This system is currently the most widely used in the world, having JFD already supplied to several other navies and Organizations such as: NATO (NSRS), Italy, Sweden, South Korea, Singapore, Australia and most recently two complete systems for the India Navy.

The JFD System is the only existing system in the world that could be loaded on current BNMearim District ships, as the competing system needs the DP2 (+) requirement that does not exist on those ships.

Ship Lifting and Transfer Systems

LOGSUB together with the Norwegian company TTS Syncrolift AS supplied and assembled in South America two complexes Ship Lifting and Transfer Systems, one to the Brazilian Navy at the Naval Military Complex of Itaguaí, for submarine construction design projectof this Navy and another for the SIMA Callao Shipyard of the Peruvian Navy for the Navy Modernization Project.

In both projects LOGSUB was responsible for receiving logistics and supported TTS in the assembly and commissioning services. Currently two more mainland navies are developing similar projects for the expansion and modernization of their naval industrial facilities and LOGSUB is responsible for the initial technical / commercial support.
