Course content

Environmental conditions-loads-load effect-resistance. Examples of structural failures. Description of various marine structures. Ship hull girders and principles for structural drawings. Fundamental structural mechanics. Analysis of beams, beam grilllages and frames. Hull girder loads in still water, moment and shear force distributions. Interaction between structural components. Combination of stresses. Design codes. Analysis of frames with sidesway prevented with the deformation method. Matrix formulation of the deformation method. Application to transverse frames in ships and trusswork plattforms. Buckling of columns and beam-columns. Structural design of truss-work plattfoms and floating platforms

Learning outcome

The subjects Marine Technology Intro and Marine Technology 1, 2 and 3 shall together enable the students to describe and understand the basics of marine technology and carry out engineering tasks related to design, construction and operation of marine systems such as ships, other vehicles, offshore platforms and other marine systems. In addition they shall give the students a proper set of tools and methods for carrying out such work and training in the skills of communication and teamwork. Marine Technology 2 shall give the students basic understanding of the ship hull girder as a structural system, knowledge of fundamental methods for analysis of stresses and forces in beams and frames, their resistance to buckling as well as skills in practical use of the methods for analysis of structural components in the hull girder.

Learning methods and activities

Lectures, laboratory exercises and conventional exercises, partly PC-based. Mandatory project work on structural analysis with the matrix method using MATLAB. All laboratory exercises and a fraction of other exercises are mandatory. Presence in lecture on structural drawings for ship fabrication may be mandatory.
Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (75%) and exercises (25%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade. Postponed/repeated exams may be oral.
