Industrial waste - destination and valuation techniques of floating hoses: case study in Macaé, RJ

Abstract

A large part of the oil extracted in Brazil today, is drained to the coast, or even transported to larger vessels through Floating Hoses. This oil unloading operation is called Offloading, it is of fundamental importance for the performance of offshore operations. These operating units use storage systems and oil relief, which can be FSO (Floating Storage Unit and Transfer) or FPSO (Floating Production Unit, Stockpiling and Transfer). In this oil transshipment scenario, floating hoses have primary role therefore they are responsible for this operation. The Floating Hoses after useful life are discarded. How do the environmentally correct disposal of this waste? The destination most used for this waste are the landfills Class 2, for non-hazardous waste. In this study, we attempted to develop appropriate allocation techniques for Floating Hose, in order to obtain a greater appreciation potential of the materials that compose it, as well as presenting the risk of these being put up in a landfill, even if it is a controlled landfill. This technique is based on a so-called Reverse Manufacturing, all components are reused and recovered, with a more environmentally sound and economically viable destination. The research methodology was based on empirical studies of phenomenological framework, involving operational staff of a medium-sized company with a rising share of Treatment and Waste Disposal Market, in the city of Macaé. It was evidenced in the survey that there is a possibility of potential gains from the application of reverse manufacturing techniques of hoses, both in terms of environmental liability reductions and the financial return through the recovery of materials that compose them.
