Ships Structure Fundamentals

Presentation

This training course describes the various elements of the ship's structure, the loads acting on the structure and the required strength of the ship's structure to sustain such loads.

Objectives

On completion of the training, students will be able to:

Know the typical structural arrangements of different ship types. Understand stiffened panels as the fundamental structural units in ship structures and know the different framing systems used in ship construction

Know the different types of loads acting on the ship's structure and understand the static sea pressure and the wave induced dynamic sea pressure. Understand the concept of net loading on the ship's structure, shear forces and bending moments. Get familiar with fatigue loads

Understand the stresses on ship's structure including longitudinal stresses on hull girder, stresses on primary supporting structure and local stresses and the strength of the ships structure. Get familiar with fatigue strength and understand the corrosion and the net scantling approach.

Program

Module 2 – Loads on Ship Structure

Classification of loads acting on ship structure

Static and dynamic loads

Sea pressure

Internal loads

Net load on structure

Bending moment and shear force

Alternate loading condition

Module 3 – Strength of Ship Structure

Ship structural strength

Stress classification

Spreading of loads through the ships structure

Hull girder strength

Strength of primary structure

Finite element modelling analysis

Strength of plates and stiffeners: Stress check, section modulus, buckling strength

Fatigue strength

Corrosion of ship's structure, consequences of general corrosion

Net scantling approach

Certificate

On completion of the training program, the student will be awarded:

A Certificate of Ship's Structure Fundamentals, issued by Bureau Veritas Solutions Marine & Offshore.

The Certificate of Ship's Structure Fundamentals is obtained after completing the course and passing the online test.
