15. ITN –Naval Technology Institute
The ITN is designed to have 4 areas of activity.
Phase I began during the 3rd quarter 2011
 Phase I- Qualification and Training
— on 1st July 2011, OSX entered into an agreement with FIRJAN for the training of up to
3.100 pepole in 23 job functions (welders, mechanics, among others)
— in this first phase, SENAI’s facilities and faculty in the city of Campos shall be utilized as
well as mobile units in São João da Barra
— classes shall commence in 2012
— estimated investment for this phase is approx. R$ 12.7 million

16. ITN –Naval Technology Institute
 Phase II- Training at UCN Açu:
— contemplates several training activities, technical assistance and supervision of operations in
partnership with Hyundai (40 specialists based in Brazil for 5 years)
— 50 employees from UCN Açu to be trained at Hyundai’s shipyard in Ulsan, South Korea
— construction of ITN at UCN Açu, with an area of approximately 1,800 m2
— facilities for workshops, labs, classrooms, auditorium and library
— implementation of systems for simulation of operations of offshore units
Phase 1 – Employee Training

17. ITN –Naval Technology Institute
 Phase III- Supply Chain Strengthening
— Identification of suppliers that have the potential to develop new materials,
equipment and innovative work methodologies, focused on OSX’s potential demand
 Phase IV- Technological Innovation
— The ITN will establish partnerships with Brazilian and international academic
institutions, focused on the development and assimilation of new technologies.
