AbstractThis work presents the approach used at PETROBRAS to develop new suppliers in the local and international market as to provide innovative equipments to the deep water exploration and production activities. The task of pushing up the industry limits to foster the manufacturing of new prototype pieces of equipment at a commercial scale has been addressed by PETROBRAS for more than 15 years in a join effort between the Exploration and Production area and the Procurement Department. Significant results have been achieved especially in the development of new local suppliers. The paper presents a general overview of the PETROBRAS Technology Management Model and how the process of developing a prototype equipment is inserted into it. The main challenges of such developments and the solutions used to figure them out are discussed. The conceptual basis of the criteria and objective approach used to select a particular manufacturer to a specific project named the Innovation Potential Evaluation Index is presented also. At the end of the paper the results achieved so far in the increase of the registered new suppliers and a portfolio of the equipment developed are presented as well as the perspectives for the increase of local content due to future initiatives.

Since World War I, the commercial aviation industry has seen many improvements that now allow people and goods to reach the other side of the world in a few hours, consuming much less fuel than in recent decades. Improvements in cargo capacity and energy efficiency were significant, and in this scenario, commercial airlines were able to thrive and bring great benefits to the world economy. However, this sector is facing environmental challenges due to the intensive use of jet fuel. Brazil is one of the largest domestic air passenger markets in the world and still has great growth potential, considering its economic potential and territorial dimensions, which are roughly the same size as the US and twice the size of the European Union. This paper discusses the partial productivity of jet fuel in Brazilian domestic aviation and proposes an econometric method to support public regulators and airline decisions. The proposed model uses variables, such as aircraft size, route characteristics, and idle flight capacity, in a panel data analysis. The results show that reducing idle capacity is one of the best ways to achieve better short-term fuel efficiency, and therefore will reduce the environmental impacts and have positive economic effects on commercial air transport activities. This paper brings a new approach to the discussion of airline performance, focusing on the use of jet fuel, with economic and environmental consequences.
