1. Marine structures
The aim of this profile is to design and dimension marine structures optimally to fulfill both functional and safety demands. A master level of structural mechanics, is vital to verify testing and analysis and to develop new structures.
This study profile teaches the calculation and estimation of the effects of hydrodynamic and other loads; movements, deformations and internal forces in fixed and floating platforms and ships. Deformations and the strength of constructions are also important calculations, and must be controlled as regards the requirements of the operator and the authorities. Students are also trained in the evaluation of alternative solutions in view of requirements related to function and safety.
Keywords: Stress/tension, deformations and vibrations in constructions, construction analysis, materials and capacity, safety and reliability.
Learning knowledge and skills of Marine Structures
The purpose of your study in structural engineering is to enable you to carry out structural analysis of different types of marine structures, assess the results as well as apply the knowledge and skills to design and dimension marine structures. This includes establishing models for structural analysis, calculating loads and load effects as well as demonstrating that functional and safety requirements are fulfilled.
Students that have completed this study specialisation shall
- Have a deep understanding of key concepts within solid mechanics, such as equilibrium, stresses, strains, basic material laws and stability.
- Master the theoretical basis for analytical prediction of the behaviour of different types of structures, like truss works, frames as well as plates in bending and with in-plane loads.
- Have a good knowledge of the Finite Element Method for structural analysis of different types of structures with linear behaviour and a basic knowledge about nonlinear behaviour due to large deflections and inelastic material behaviour
- Have good knowledge about hydrodynamics and structural dynamics
- Have a good understanding of the loads acting on marine structures including functional and environmental loads, especially from ocean waves, and accidental loads, and how they vary in time and space, and master methods for estimating their effect on structures, including their statistical characteristics
- Have a good understanding of design criteria in general and a detailed knowledge about ultimate and fatigue strength criteria as well as how they are specified in design standards for marine structures
- Have a good understanding about how structures carry loads and how this understanding can be utilised to optimise the design of structures
The student shall be able to
- Carry out sufficiently accurate calculations of structures by using internationally recognised computer programmes based on the Finite Element Method and assess the results, based among other things on the convergence characteristics of the finite elements
- Make simplified estimates of structural behaviour for comparison with the results of finite element analyses to support structural design
- Suggest good design of different types of structures
The student shall
- Have a basic understanding of the behaviour of load carrying marine structures and construction materials
- Be creative, constructive and critical in his engineering endeavour – and especially have a critical attitude to results obtained by computer software of inestimable use, such as e.g. the Finite Element Method.
- Have knowledge as for the marine technology study programme in general
