TECHNOLOGIES OF CONSTRUCTION AND OUTFITTING OF SHIPS
Educational objectives: they are mainly related to the correct knowledge of the main typologies of ship constructions, with reference to ship classification, rules, materials, connections, structural details and fabrication techniques. The skills of classifying the ship structures and reading the ship structural drawings, by the analysis of several schemes of existing ships carried out during the course, are additional objectives of the course.
Knowledge and understanding: Students shall prove to know the main topics related to ship technology and construction, with reference to ship typologies, fabrication techniques, connections, materials and classification. Finally, students shall be capable of determining the section modulus of some basic sections, in order to assess the bending strength.
Ability to apply knowledge and understanding: Students shall prove to apply the acquired topics and theoretical proficiencies, required to correctly read the ship structural drawings, with main reference to the ordinary and reinforced transverse sections, and the watertight transverse bulkheads. Besides, students shall be capable of correctly determining the section modulus of ordinary stiffeners with attached plating.
Judgment autonomy: Students shall autonomously evaluate and classify the main ship typologies, the applied materials, by correctly reading and understanding relevant structural drawings and schemes.
Communicative Skills: Students shall acquire the skill of reading the section schemes of main structural elements of ships, also with reference to the applied materials and the most suitable welding techniques.
Learning Skills: Students shall be capable of continuously update their skills, by reading books, articles and rules (mainly in English), in order to acquire a good capacity of enhancing the own knowledge in the field of ship technology and construction.
It is required to have learnt the basic elements of maths.
SHIP CLASSIFICATION (6h)
Classification depending on displacement type, navigation extent, propeller typology and service. Analysis of typical cross-sections of bulk carriers, oil tankers, containerships, ro-ro/pax ships and chemical tankers.
HULL MATERIALS (10h)
Classification of hull steels: yielding strength and grades. Tensile test for ductile materials. Charpy test. Classification of light alloys. Composite materials embodied in the shipbuilding sector. Pre-fabrication techniques. Glass content. Electric arc and TIG/MIG/MAG weldings. Welded joints and preliminary operations.
STEEL HULLS (32h)
Basic elements of steel hulls: bottom, side and deck structures. Typical hull girder cross-sections having transverse, longitudinal and mixed layout. The hull girder bending moment. The Navier formula. Section modulus of typical hull stiffeners. Section modulus of the hull girder cross-section. Detailed analysis of a 35000 DWT bulk carrier. Basics of corrosion wastage. Renewal criteria of corroded structures.
The course furnishes the basic elements concerning the classification and main ship typologies, the hull materials with particular reference to steel and light alloy, the main ship construction typologies and loads acting on the hull girder, as well as the most commonly applied welding techniques. The course is subdivided into three parts:
-SHIP CLASSIFICATION (6h)
-HULL MATERIALS (10h)
-STEEL HULLS (32h)
