Sensores de vento aplicados a sistemas de posicionamento dinâmico: Um melhor entendimento sobre os seus efeitos, vulnerabilidade e riscos as operações offshore

Abstract

The present work addresses in an applied, explanatory and descriptive way the relationship between wind sensors and dynamic positioning systems. The main objective of this work is to resolve doubts about the effects of wind sensors on dynamically positioned vessels, as well as to describe and analyze the main risk scenarios applied to the Offshore environment. In total six daily and current scenarios were discussed and described. These scenarios where dynamically positioned vessels may react unexpectedly and / or undesirably, thus surprising the operator and subjecting the operation to an operational risk framework. These reactions were described and analyzed based on the philosophy of DP systems, emphasizing the relationship between wind sensors and dynamic positioning systems. In addition to such analyzes, specific recommendations regarding each scenario will be suggested in order to improve the operators' understanding of the real impact of the wind input on the DP plants. Such knowledge will provide safer and more efficient operations, not only with a view to contingency, but also offering an explanatory content that allows operators to anticipate scenarios that may lead to potential risk. As intermediate objectives we will mention definitions, classifications, operating philosophies, employability, errors, failures, advantages and disadvantages always focusing on wind sensors and their direct influence on dynamic positioning systems. Including providing material, the result of a first study, which can assist as a basis for future research even more technical and deep, as well as applied practical guide and reference source to all dynamic positioning operators and stakeholders.
