Abstract(s)
A corrosão em navios petroleiros é a principal causa da sua degradação quando estes estão sujeitos a condições agressivas como é o mar ou mesmo danificações mecânicas nos próprios cascos. Neste relatório de estágio irei abordar como se faz a manutenção em navios petroleiros de forma a minimizar os danos causados pela corrosão. Para tal iremos abordar os diferentes tipos de operações que podemos desenvolver de tratamento superficial e os diferentes tipos de recobrimentos que potenciam um efeito barreira contra os meios agressivos a que estes estão sujeitos.
Para além dos trabalhos desenvolvidos serão abordados métodos de controlo de qualidade bem como os requisitos de especificações de pintura de forma a conseguir a qualidade adequada à utilização e durabilidade.
Foi escolhido um projeto (navio) em que temos dois trabalhos distintos de forma a alargar um pouco os diferentes tipos de tratamento superficial e recobrimentos. Iremos para tal ter um trabalho desenvolvido no costado de um navio e convés, envolvendo diversos tipos de equipamento e tipos de revestimento.
No final do projecto foram atingidos os objectivos propostos inicialmente conseguindo-se deixar o navio protegido contra os meios agressivos, fazendo o cliente final satisfeito com o resultado final.
Corrosion in oil tankers is the main cause of their degradation when they are subjected to aggressive conditions such as the sea or even mechanical damages in the hulls it self. In this traineeship report I will discuss how to maintain oil tankers in order to minimize damage caused by corrosion. For this we will address the different types of operations that we can develop for surface treatment and the different types of coatings that enhance a barrier effect against the aggressive means to which they are subject. In addition to the developed works will be approached methods of quality control as well as the requirements of painting specifications in order to achieve the right quality for the propose and durability. A project was chosen (ship) in which we have two different works in order to slightly extend the different types of surface treatment and coatings. We will have a work developed on the side of the ship and one on the deck, involving various types of equipment and coating protection. At the end of the project, the initially objectives were achieved, leaving the ship protected against possible aggressive means and the end customer satisfied with the final result.
