Læringsutbytte

The course shall provide a comprehensive understanding of fundamental concepts, models, and methods in marine technology. It is tailored towards students having an undergraduate degree in mechanical or civil engineering, and the teaching will seek to extend core engineering concepts that the student is already familiar with into the maritime domain. The course learning objectives are targeted towards four topic areas, as follows:

Hydrostatics and stability:

The overall learning goals or this module is for the students to understand and be able to apply fundamental theory of hydrostatics for describing, developing and analyzing ships and floating structures. This includes:

• Apply basic principles of displacement, stability and floatation on both arbitrary objects and specific marine constructions
• Explain core terms in naval architecture
• Be able to develop a hole form based on line-drawings, parameters and form coefficients
• Know how to analyze transverse stability on ships and floating structures
• Be able to analyse dynamic stability
• Analyse damage stability. Understand fundamental principles of probabilistic damage stability.
• Be able to develop a general arrangement, and determine freeboard and load lines

Marine power systems:

• Identify engineering challenges associated with specifying and designing the power/energy source aboard a vessel.
• Understand the power demands onboard with introduction to load profile.
• Introduction to the machinery and layout of prime movers, electrical generation and various subsystems for different vessel types
• Introduction to the diesel engine as most common prime mover, the fuels used and how they are utilized in the engine.
• Introduction to marine electrical systems

Hydrodynamics:

This covers topics in linear wave theory, floating bodies in waves and ship resistance and propulsion, and have the following learning objectives:

• Know the basic assumptions of potential flow theory and how to make use of a velocity potential to calculate flow variables.
• Know the assumptions of linear wave theory and general properties of linear waves, including conditions on the free surface and wave dispersion relation
• Know how the dynamic equation of a floating body in waves is obtained and be able to explain the different forces/loads involved.
• Know the concept of a response amplitude operator and make use of characteristics of a linear harmonic oscillator to explain body motions, resonance, natural frequency, effect of damping.
• Know the basics of how scaled model testing of ships is performed.
• Know the main resistance components and how they can be determined.
• Know the concept of Froude scaling.
• Explain how a propeller works and choice of propeller based on propeller diagrams.
• Explain how a propulsion test is conducted and purpose of doing it.

Structures:

The module comprises a review of the the structural configuration and behavior of ship hull girders, truss-work platforms and floating platforms. It gives an introduction to fundamental methods for static analysis of forces and stresses in beams, girders and frame structures, plastic analysis of ultimate strength, their resistance to buckling and application of these methods to analysis of relevant structural components

• Conduct calculations of global still water shear force and bending moment in the hull girder on the basis of hydrostatic data and load conditions
• Describe the structural configuration of the ship hull girder
• Understand and describe the force transfer in the hull and the interaction between them the hull girder components
• Conduct simple calculations of de principal hull stresses and their combination
• Describe how the solution with the deformation method can be systematized by means of matrix formulation
• Determine ultimate strength by means of plastic methods of analysis of beams and frame structures
• Describe how elastic buckling of columns can be analyzed by solving the differential equation and the principle of minimum potential energy
• Calculate the critical load for relevant beam-column components in marine structures

Læringsformer og aktiviteter

Learning is based on both ordinary classes and assignments. The assignments focus on applying methods for realistic cases.

Mer om vurdering

The grade in the course is based on the weighted average of a written examination in each of the four core topics. Examination papers will be given in English only. Postponed/repeated exams may be oral. For a re-take of an examination, all assessments during the course must be re-taken.
