The courses in Marine Technology, namely the Marine basics, Structures, Hydrodynamics and Propulsion systems, safety and environment shall together enable the students to describe and understand the different aspects of marine technology and be able to carry out necessary engineering tasks related to design, construction and operation of marine systems. In addition, they shall give the student an overview of tools and methods for carrying out such work and certain training within communication skills building and teamwork. Marine Technology - Propulsion systems, safety and environment shall provide the understanding of modes of operation and performance with emphasis on design and operation of main machinery, electric power generation, distribution and electric propulsion, as well as the safety and reliability analysis of machinery systems. Upon completing the course the student should be able to: Hybrid and Electric Propulsion Systems: At the end of this section, the students are expected to: - Have the basic knowledge for the analysis and operation of shipboard electric power and propulsion systems and marine installations. - Understand basic electrical engineering for marine installations; analyze electric circuit networks including DC and AC circuits. - Define power flow in DC systems, and single- and three-phase AC power systems, generalize the power flow analysis to typical marine electrical power systems; calculate generated/consumed power by electrical machines; and describe the concept of power flow in marine electric distribution systems. - Explain the principle of electric machines including transformers and rotating machines, describe different topologies of electric machines applicable to marine propulsion, distribution and marine power generation, and model the electric components by equivalent electric circuits. - Understand and explain the principles of electric motors, motor drives and control of electric propulsion. - Understand the principle of hybrid power systems with batteries and fuel cells, and how it can contribute to reduced fuel and emissions. Conventional machinery: At the end of this section, the students are expected to be able to: - Quantify the power requirement of a certain vessel at various phases of operation and establish operating profiles. Estimate fuel consumption and exhaust emissions based on a specified operating profile, and also evaluate how changes in the operating profile may influence fuel consumption and exhaust emissions. - Understand basic principles of combustion and such definitions as heating value, excess air ratio, lean and fuel-rich combustion. Perform simple computations of the combustion process based on energy and mass balance. - Describe and analyze working cycles of internal combustion engines and gas turbines by means of p-V and T-s diagrams.

Explain terms used for describing performance of diesel engines and gas turbines related to power, energy utilization and exhaust emissions. - Compute, by means of mass and energy balance and simple process models, how performance of diesel engines and gas turbines is affected by external factors (atmospheric conditions, fuel quality) and internal factors (compression ratio, charge air pressure/pressure ratio in compressor, inlet temperature at turbine, etc.) RAMS: At the end of this section, the students are expected to: - Understand and be able to quantify component reliability. - Understand and calculate system reliability with reliability block diagrams and structure functions. - Understand and utilize fault tree analysis to characterize reliability and risk of technical systems. - Understand the meaning of system availability and how it can be calculated for complex and redundant systems. - Understand basic principles for maintenance management and know different types of maintenance, as well as the importance of maintainability. - Be able to calculate how system reliability can be improved through preventive maintenance. - Understand the basics of system optimization with respect to RAMS requirements. - Be able to use economic criteria, such as net present value, internal rate of return, and payback period, to assess design concepts and maintenance strategies. - Be able to use basic methods of risk analysis.
Learning methods and activities
Lectures, project assignment, laboratory exercises and conventional assignments. The project assignment and laboratory exercises carried out in groups are mandatory. Some/a share of the conventional assignments may be mandatory for access to the exam. The course may include a mandatory seminar series that requires at least 50% participation.
Further on evaluation
Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (70%) and exercises (30%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.
In order to pass the course, all parts of the exam must be assessed to having a grade level corresponding to passed.
If there is a re-sit examination, the examination form may change from written to oral. For a re-take of an examination, all assessments during the course must be re-taken.
Compulsory activities from previous semester may be approved by the department.
