Course content

Application of electrical power in marine installations for production of oil&gas and subsea oil&gas process installations. Power generation, dynamic models of rotating machines, short circuit analysis, start-up of large motors, cable modelling and subsea cable networks. Subsea motors and subsea high voltage equipment. Electrical heating of subsea pipelines.Offshore power grid.

Learning outcome

After completing the course, the student shall:
- have an overview of utilization and application of electric power in offshore installations both on the suface and the seabed.
- understand dynamic modelling of rotating machnines.
- understand methods for short circuit calculations and determination of short circuit ratio.
- have an understanding of problems related to large machines in weak power grids.
- understand modelling of power cabels for subsea transmission grids.
- have an understanding of the design and construction of high voltage components for installations on the seabed.
- know how electric power is being used for heating of pipelines.

After completing the course, the student shall be able to design, construct and analyse marine power systems, with focus on power systems in installations for oil and gas production, installations on the seabed for processing of oil and gas and offshore power grids for transmission of electrical energy.

Learning methods and activities

Lectures and compulsory exercises. Analysis of marine power systems with relevant simulation software.
The course is given in English.

Compulsory assignments

  • Øvinger

Further on evaluation

The final evaluation will be based on a written examination (counting 75%) and a project (counting 25%) based on % fulfillment. Final grading will be from A to F.
If there is a re-sit examination, the examination form may change from written to oral.
In the case that the student receives an F/Fail as a final grade after both ordinary and re-sit exam, then the student must retake the course in its entirety. Submitted work that counts towards the final grade will also have to be retaken.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
