Learning unit contents

This lecture is given in English.
It is a lecture of the EMSHIP ERASMUS MUNDUS MASTER DEGREE (WWW.EMSHIP.EU)
This lecture includes several parts and an introduction to ship structure design and analysis is given in the lecture "Integrated design project".
1) FUNDAMENTALS OF SHIP STRUCTURES
Criterions of dimensioning, Design limit states, Rational approaches (direct calculation) of sizing (scantling) versus rules based approaches, Modern tools for modeling; Structural analysis (FEA); Optimisation, .... An important part of the course includes practical exercises (weekly).
2) ULTIMATE STRENGTH, RELIABILITITY ANALYSYS, FATIGUE, VIBRATION and  OPTIMISATION
Description of the various limit states (service, ultimate, accident, ..) of the ship structure (yielding, buckling and tripping of beams, buckling and ultimate strength of plates and stiffened plates, ultimate bending moment of hull girder, fatigue (curves S-N), vibration, collision & grounding, ...). Ultimate strength of hull girder: simplified approach, curvature - bending moment curve and average stress and strain curve of the components (progressive collapse analysis, Smith method), non-linear analysis, fluid-structure interaction .... - Vibrations: theory of vibrations (basic notions); technology aspects: Cause of vibrations in ship structures; Techniques of measurement, control and prevention techniques; practical impact on design. - Structure reliability concepts (loads and strength) in calculation of structures (rule based approaches and direct calculations). - Materials (steel, aluminium, composite materials, sandwich panels, ...). - Introduction to ship structure optimization (least cost, least weight, ...).
3) SHIPYARDS & SHIP PRODUCTION
Shipyard layout (organisation, implantation, functions, shipyard types, etc.) - Planning and logistics - Economical context. - Shipyard production processes. - Main steps of shipbuilding production (sequences, material flows, etc.). - Modular construction (blocks, sections, etc.). - Main workshops in shipyards (machining, cutting, bending, forming, panel line, outfitting, straightening, etc.). - Welding and cutting processes (welding types, welding processes, welds control, weld calculation). - Launching methods (dry dock, slipway, etc.) - Modern tools for production simulation and cost assessment - Concurrent Engineering tools such as Design for Production, Lean manufacturing, Quality Management, etc. - Scheduling notions (Potential and Pert methods)
4) COMPOSITE MATERIALS (Marine application)
This part complete the lecture "Materials Selection (given by Prof Ruffoni)- MECA 0462-2". This lecture is to give relevant knowledge and practical expertise to perform a ship design using composite materials. Manufacturing methods (experimental test in lab - done by students - Prof Courard). Highlights are: structural failure modes/theories of composites ship structures; and application of the Class rules and/or FEM tools for composites ship structure.

Learning outcomes of the learning unit

- The main objective is to give a general overview of the structural problems that must be considered at the conceptual design stage, early design stage and detailed design stage.
The lecture focusses on the first principle design methods and relies on rational approaches. It surveys the various limit states that must be considered for the structural design and scantling assessment.


- Concerning Shipyards: The objective is the understanding of production technologies and manufacturing methods for shipbuilding industry in order to integrate production limits at the design stage (Design for production)

Prerequisite knowledge and skills

Good knowledge in structure mechanics

Planned learning activities and teaching methods

The course includes 5 to 6 practical works. Written works are marked.

Mode of delivery (face to face, distance learning, hybrid learning)

September to Mai , organized every year. 1/2 day classes a week and 3h/week to realise practical works at home .
PArt 1 is given from Sept to Dec, with written assessment in Dec.
Part 2 to 3 are given from Feb to MAi, with asessment in June (oral part + written exam - the same day)

Organisational adjustments related to the current health context

The evaluation is based on
- a continous assessment during the year (based on homeworks, reports), 10%
- a written exam, which can be done remoteny if necesary: 40% (in June 2020)
- an oral exam, which can be done remoteny if necesary: 50% (in June 2020)

Assessment methods and criteria

Below you will find information on the evaluation methods planned for in-person and remote exams as well as those planned for hybrid sessions. Depending on how the health crisis evolves, the chosen method will be communicated to you no later than one month before the start of the exam session.

Any session :

- In-person

oral exam

- Remote

oral exam

- If evaluation in "hybrid"

preferred remote
