88261 - Offshore OIL&GAS Technologies

Academic Year 2021/2022

  • Moduli: Alessandro Tugnoli (Modulo 1) Paolo Macini (Modulo 2)
  • Teaching Mode: Traditional lectures (Modulo 1) Traditional lectures (Modulo 2)
  • Campus: Ravenna
  • Corso: Second cycle degree programme (LM) in Offshore Engineering (cod. 9249)

Learning outcomes

The aim of the course is to introduce the student to the processes and technologies for the production of offshore Oil&Gas resources. The student will gain knowledge on the offshore upstream operations and on sub-sea, top-side and floating production technologies.

Course contents

Requirements/Prior knowledge

A prior knowledge and understanding of the fundamental concepts used to describe a production process and its material and energy input/outputs is required to attend with profit this course. This implies basic knowledge of physics, chemistry and thermodynamics.

Fluent spoken and written English is a necessary pre-requisite: all lectures and tutorials, and all study material will be in English.

Course Contents

Module 1

- Design of upstream Oil & Gas processing systems

- Subsea systems

- Case studies of field developments

- Focus on a specific technology: design of gravitational separators

- Tutorials and Individual Case Study development

Module 2

- Drilling fluids, casing and cement operations. Drilling fluid engineering. Hydraulic optimization.

- Casing and cement design.

- Directional drilling: downhole motors and turbines, well path directional control technologies and directional surveys.

- Wellhead , safety equipment and BOP (Blow Out Preventers) configuration. Well control technology.

- Offshore oil well drilling operations. Marine riser, subsea wellheads and BOPs. Motion compensation systems.

Assessment methods

Achievements will be assessed by the means of a final written exam. This is based on an analytical assessment of the "expected learning outcomes" described above.

A single written test will cover both modules of the course (no separate tests are possible).

The written test will typically consist of 4-6 open questions, 1-2 applicative exercises and 1 design exercise*.

* The design exercise can be substituted by the development of Project Work during the lesson period.

Grading criteria and rules

The exam is set to evaluate the students' knowledge-level, analyzing and synthesizing abilities, and technical communication skills.

Higher grades (from 25/30 to 30/30) will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, a clear and concise presentation of their ideas and an appropriate use of technical language.

To obtain a passing grade (from 18/30 to 24/30), students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language.

A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.

If you sit the exam as part of an integrated course (12 ETCS), you must score a mark ≥18/30 on both componets; a fail grade on a component requires the test on that component to be repeated.

The passing grades of each component are normally valid for 12 months, then the mark is lost and the written test of that component must be repeated.

Requests to refuse a mark of a module ≥18/30 must be submitted to the Professors within 48 hours after you receive the graded exam, and with a written justification. After 48 hours, the mark of the module is automatically considered accepted and the test on the module can not be taken again.

An intermediate mark ≥18/30 for a given module can not be refused more than 2 times.

Final mark of the Integrated course is awarded 48h after passing both intermediate marks.

Teaching tools

Lecture slides and integrative supporting material will be available on-line by Virtuale service (virtuale.unibo.it). A password is required for access (communicated at the first lesson or upon request to the teacher).
