Análise do sistema de funcionamento de uma embarcação de lançamento de linha e manutenção de seus dutos

Abstract

The great challenge of oil exploration and production in Brazil is the development of technologies and knowledge to achieve greater depths of water, where the majority of the national reserves are found. At this scenario the flexible pipelines becomes a key component of better adaptation to harsh operating conditions due to great depths, temperature variations, strong ocean currents, waves, winds and platform's movements. The flexible pipelines are used to oil transportation, fluid injection, gas or chemicals transportation between various submerged and surface equipment. A general characteristics of these structures is its high flexibility, which justifies its use coupled to complacent structures and ability to be stored on reels and spools, reducing the transportation and installation cost. In this work we will show some processes related to submarine pipelines from the composition to its launch, addressing the general characteristics and applications, the types, and procedures for launching in deep waters based on technical visits on the Petrobras Line launch ferry (BGL-1)
