Plataformas Oceânicas

Objectives

Attaining knowledge of the global behaviour of the various types of ocean platforms, especially those for exploration and production of oil and gas, their design, their construction and installation and their operability.

Syllabus

The course is divided into seven parts. Part 1 presents the main types of platforms, the overall behavior of each type, and the construction and installation methods; Part 2 is a review of stochastic analysis of oceanic structures, focusing on the estimation of extreme responses due to wave actions; The structural design of fixed and semi-submersible floating platforms are presented in Parts 3 and 4 respectively; Part 5 deals with the stability analysis of semi-submersible platforms; Part 6 addresses the local checks of ultimate strength; and finally, Part 7 presents methods for fatigue analysis of ocean platform.

Prerequisites

Knowledge in structural and stability analyses of vessels.

Cross Competence Component

The UC allows the development of transversal competences in: (a) Critical Thinking, including strategic thinking and problem-solving approaches, in the implementation of projects by student groups; (b) Interpersonal and Intrapersonal Skills (Skills (oral, organizational and teamwork, self- discipline, perseverance, self-motivation skills ) in project implementation by groups; and (c) Information and media literacy (ability to locate and access information, as well as to analyze and evaluate media content), to collect and systematize information for the implementation of projects by student groups. The assessment percentage associated with these competences should be around 20%.

Programming And Computing Component

The UC has the following Programming and Computing components: (a) Application of DNVGL's SESAM software package, whose licenses are made available to students by CENTEC, for the execution of part of the project tasks; and (b) Development of spreadsheets using Excel, Mathcad or Matlab to perform part of the project tasks. The evaluation associated with these programming and computing components is approximately 80%.

Ethical Principles

All members of a group are responsible for all group's work. In any assessment every student should honestly disclose any help received or sources used. In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
