Learning outcome
The courses Marine technology, i.e. foundations, structures, hydrodynamics, and propulsion systems, safety and environment, shall together enable the students to describe and understand the marine disciplines and perform necessary engineering work related to design, construction and operation of ships, platforms and other marine systems. They will also give the students an overview of methods and tools for performing such work, as well as training in teamwork and communication. Marine Technology - Propulsion Systems, Safety and Environment aims to provide an understanding of operation and performance with a view to design and operation of main machinery, electric power generation, distribution and electric propulsion, as well as assessment of the safety and reliability of machinery systems.
By the end of this course students should be able to understand and describe a typical propulsion/power system on board a vessel, give a brief overview of each part of the system, and apply basic analyses of fuel, power and the reliability, availability, maintenance, and safety expected for the system. The student should also have an appreciation of the environmental impact of different systems, mainly in terms of emissions.
In particular for each part:
Hybrid and electric propulsion
At the end of this section, students are expected to:
- Have basic knowledge for analysis and operation of hybrid (electric) power and propulsion systems onboard ships and maritime installations.
- Define electrical power in 1- and 3-phase AC circuits and relate this to typical marine electric installations; and demonstrate insight into power flow in maritime electrical distributions.
- Understand the basics of electric power systems for vessels, including AC and DC grid, and power management system.
- Explain the principle and modes of operation of electrical machines for marine systems; demonstrate various topologies of electrical machines relevant to propulsion systems, distribution, and maritime power generation; and model these using equivalent circuits.
- Understand and explain the principles of electric propulsion and associated controllers for marine vessels.
- Understand the principles of hybrid battery and fuel cell power systems, and how they can contribute to reduced fuel consumption and emissions as well as possible zero-emission.
Engine and fuel
At the end of this part, the student is expected to:
- Quantify a vessel's power requirements in different operational phases and describe this using operating profiles.
- Calculate fuel consumption and the amount of exhaust emissions to the atmosphere, based on a given operating profile, and assess how changes in the operating profile may affect consumption and emissions.
- Be able to apply the principles for design of the main machinery in a vessel based on a given operating profile.
- Understand the principles of combustion and know elementary concepts such as calorific value, excess air, lean and fuel-rich combustion.
- Be able to perform calculation of the combustion process using energy and mass balance.
- Be able to describe and analyze work processes for internal combustion engines using p-V diagrams.
- Calculate simple thermodynamic circle processes to determine energy utilization and work yield.
- Be able to explain the main components of the machines, the principles of energy conversion and typical operating characteristics of diesel engines.
- Be able to explain key concepts that describe a diesel engine's performance related to power, energy utilization and exhaust emissions.
- Be able to provide a basic description of the auxiliary systems (cooling, lubrication, fuelling) that support the operation of an engine.
RAMS
At the end of this part, the student is expected to:
- Understand basic concepts related to risk and safety, and be able to apply some methods in risk analysis, with particular emphasis on machinery systems.
- Understand and be able to quantify a component's reliability.
- Understand and calculate the reliability of complex systems with redundancy, such as marine machinery systems, using reliability block diagrams and structure functions.
- Understand and be able to apply fault tree analysis to calculate reliability and risk to technical systems.
- Understand what is meant by system availability and be able to calculate availability, including for redundant systems.
- Understand principles for maintenance management and planning, and know different types of maintenance, failure patterns, and the importance of maintainability.
- Be able to calculate how a system's reliability can be improved by preventive maintenance.
- Understand basic optimization with respect to RAMS requirements for a system.
- Be able to apply economic criteria such as net present value, internal rate of return, and payback period to evaluate design concepts and maintenance strategies.
Learning methods and activities
Lectures, project assignment, laboratory exercises, and ordinary assignments. Some/a share of the assignments may be mandatory for being eligible for the exam.
Compulsory assignments
- Compulsary assignments
Further on evaluation
The course grading is based on aggregated assessments, including a written exam and laboratory assignments. The results for the two parts are assigned letter grades (AF). In order to attend the exam, compulsory exercises must also be passed.
If there is a re-sit examination, the examination form may change from the written exam to the oral exam. For a retake of an examination, all assessments during the course must be re-taken.
