OVERVIEW

The course presents main elements of shipbuilding, ranging from description of ship types and their hull structural lay-outs and equipment, to its scantling design methods as well as structural design rules and ship in service management and maintenance.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims at providing students with professional competences about fundamentals of shipbuilding and ship structures, showing typical methods and languages, i.e. structural plans and drawings, to describe the hull, its structural lay-out, its components and equipment. Various merchant ship types are presented, highlighting peculiarities of each. The course includes a description of ship structural design and analysis from a global view to construction details. The general scantling criteria of ship structures and components is also summarized with reference to rules and regulations of classification societies.

AIMS AND LEARNING OUTCOMES

The student will have understanding about shipbuilding and ship scantling design, including typical language, i.e. technical ship drawings, and methods for the different merchant ship types. Moreover, the student will know and will be able to properly apply rules of classification societies and requirements of international conventions about ship construction and strength, including those applicable to ship in service and for ship management and maintenance.

PREREQUISITES

Knowledge of basic mathematics and physics concepts, content of the ship stability course

Teaching methods

Lectures and guided exercises (visits in labs if possible). Totally, 90 hours of lectures.

SYLLABUS/CONTENT

The course is approximately divided into three parts as it follows:

First part: in this part of the course the ship types are presented first along with their structural lay-outs. The fundamental nomenclature of the shipbuilding sector, the general definitions and components of the hull, main dimensions and characteristic shape coefficients are defined. In addition, displacement, light ship, deadweight, net weight, load line, tonnage and the division of the displacement into elementary weights are analysed in detail. Finally, the shipbuilding technical drawing methodologies are explained and real structural drawings are illustrated.

Second part: in this part of the course main hull scantling design principles and criteria are presented. The basis of the simple beam theory is introduced and its application to the ship structures is presented. The main loads acting on the ship, both at local and global level, are carefully analysed together with the main limit states used for the design of ship structures. Particular attention will be given to the ship global structural response and the basis for the calculation of still water shear force and bending moments will be given to help students understanding the background of loading management software.

Third part: in the last part of the course, the ship-in-service issues are presented. At first, applicable international conventions (i.e. SOLAS, MARPOL, ILO conventions, etc.) as well as rules of classification societies are analysed in detail, focussing on statutory requirements and classification concept. The organization of maritime management regime of a ship since her construction, rules & regulations, class roles, shipyard and shipowner position are reviewed mainly referring to documentation of IACS and its members. Classification of ships and certification of equipment and components are outlined. Ship’s typical degradation modes in operation for each type of ships and relevant inspection and maintenance countermeasures are later presented, including description of phenomena and testing techniques for detection of main damages of ship structures (corrosion, fracture, fatigue, mechanical damages, collapse).

LESSONS

Teaching methods

Lectures and guided exercises (visits in labs if possible). Totally, 90 hours of lectures.

ORARI

L'orario di tutti gli insegnamenti è consultabile su EasyAcademy.

EXAMS

Exam description

Oral discussing all topics presented during the course and the reports of exercises developed during the lectures. Further details will be given during lectures.

Assessment methods

Oral examination will start discussing the practical exercise and will continue to ascertain comprehension of theoretical content of the course. It is checked the student knows all main topics presented and understood relations among each other. Application examples are proposed to verify whether the student is able to use the content of the course in typical professional scenarios.
