Course content

The main objective of the course is to give the students an introduction to electro-technical engineering and an understanding of marine electric power systems on ships and platforms, which is of importance for management, engineering, design, and analysis.

The course starts with an introduction to electric analysis techniques, with basis on electro-technical concepts, laws, and properties for electric systems, such as circuit analysis, electric power, 1-phase and 3-phase systems, phasor diagrams, electro-magnetic energy conversion, and physical principles of transformers and electric machinery.
The course continues with a study of electric machines, motors, and propulsion drives, electric power generation and distribution, power management systems (PMS), operational issues, and class rules and methods for independent testing and verification.

Learning outcome

At the end of the course, the student should be able:

- describe basic electro-technical laws and methods for understanding and analysis of simple electric circuits, and to apply these to calculate relevant parameters.
- define electrical power in single- and three-phase AC circuits and relate this to typical marine electrical power plants, to calculate generated or consumed power by electrical machines, and to demonstrate insight in power flow in marine electric distributions.
- explain the principles of operation and energy conversion of transformers and rotating electrical machines, and to model these by use of equivalent electric circuits for the purpose of circuit analysis of marine electrical power plants.
- describe typical electrical propulsion drives and explain their properties and differences of application.
- propose an electric distribution and electric propulsion drives for a typical marine vessel based on the specification, operational profile, and class rules.
- explain the main principles of diesel-electric power generation in terms of engine speed, electric frequency, excitation system, and system voltage, to model the speed dynamics of a diesel engine and to relate this to the generated electric frequency, and to model the generator excitation system and relate this to the system voltage.
- describe how to connect a generator set to a power bus, to explain the principles of power load sharing between several parallel connected generator sets, and to explain the behavior of connected generators due to power load changes and faults.
- define a power management system (PMS), to describe typical PMS topologies, to explain its main functions, and to design, implement, and test some PMS functions in software.
- understand and explain the main class rules and regulations, including important terms and concepts, applicable for marine electric power plants, to explain alternative classification notations, and to describe relevant methods for verification and testing of different parts of the electrical installation.
- write project reports with a clear and concise exposition of results, assessments, and conclusions, and to orally present the results of a project assignment in a clear and efficient manner, within time limits.
- conduct academic studies and written work in an honest and ethical manner, without any sort of plagiarism in work assignment, project reports, and presentations.

Learning methods and activities

Lectures and exercises (calculation and computer exercises).

Compulsory assignments

  • Project work
  • Exercises

Further on evaluation

Portfolio assessment is the basis for the grade in the course. The portfolio includes a written exam (70%) and project works (30%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.
Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
Postponed/repeated exams may be oral.
For a re-take of an examination, all assessments during the course must be re-taken.

Specific conditions

Compulsory activities from previous semester may be approved by the department.
