Course description

Education objectives: the main educational objectives of the course are related to the knowledge of the manoeuvring qualities and the factors that determine them. The course is focused on the steering and manoeuvring systems, on the ship’s characteristics that determine the manoeuvring ability and how they can change in shallow and/or restricted water, or in the presence of wind and current, highlighting the actions to be undertaken. Besides, the course deals with the issues related to the standard manoeuvres and the information obtained from them. Besides, the correct interpretation of the main international Rules for the ship manoeuvrability is a further objective, which is reached by the analysis of the main international rules, the discussion of several case studies and the application to existing reference ships.

Knowledge and understanding: students shall prove to know the main topics related to the government and manoeuvring of the ship.

Ability to apply knowledge and understanding: students shall prove to apply the acquired topics and theoretical proficiencies, required to evaluate the manoeuvrability and propulsion characteristics of the common types of ship.

Judgment autonomy: students shall autonomously evaluate and assess the ship manoeuvrability and propulsion characteristics applying the best resolutions to increase them.

Communicative Skills: students shall acquire the skill of presenting a numerical application about the analysis of standard manoeuvres simulated in laboratory.

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 Manoeuvrability.

Prerequisites

Even if not mandatory, it is suggested to have passed the exams of Ship geometry and hydrostatics, Maths and Physics.

Syllabus

Motion’s equations, control and government systems (C.1/C.2): course stability degrees; positions and ship motions; motion’s equations; external forces; motion’s equations in algebraic form; the derivatives in non-dimensional form; the decoupling of the sway and yaw equations; Nomoto indices; the intrinsic stability of the route; the parameters on which stability depends; the Norrbin index; mechanical interpretation of the turning circle and rotation diameter; reduction of rotation diameter; the theoretical and experimental determination of the coefficients of the linearized motion’s equations; captive tests; tests with the mechanism of planar motion; the non-linearized equations and the calculation of the route resulting from a manoeuvre; active and passive devices; control and manoeuvring systems; types of rudders, rudders area, rudder shape, rudder positioning; classical and alternative solutions for manoeuvring and propulsion; optimization of propulsive performance.

Sea trials (C.5): the standard manoeuvres; the standards set by the IMO for manoeuvrability; the turning circle manoeuvre; crash stop and inertial stopping test; the spiral manoeuvre (by Dieudonnè); the reverse spiral manoeuvres; the zig-zag and zeta manoeuvres; the pull-out manoeuvre and the minimum standards for the straight-line stability; Williamson test; indices derived from standard manoeuvres; information recommended on board; IMO Resolution A.601 and Resolution MSC.137 (76); the pilot card; wheelhouse poster; manoeuvring booklet.
Characteristics of manoeuvring in narrow water and shallow water (C.3/C.4): effects of load condition, trim and speed on the ship manoeuvrability; manoeuvres in restricted waters; the effects of current and wind; shallow waters effect, sluggish movement and squat effect; interaction between ships and between ship and shores; under keel clearance; COLREG 72 (regulation to avoid collisions at sea).

Anchoring and mooring of the ship (C.6): mooring and unmooring in various situations of wind, tide, current, with or without tug; choice of anchor; anchoring with one or two anchors; length to use for the chain; anchoring in deep and shallow water.

The course deals with the elements required to ensure the knowledge of the theoretical and practical fundamentals of the controllability and manoeuvre of ships.

The course furnishes some competencies required by the STCW Convention, as amended, for Deck Officers at Operational Level, embodied in the MIT decree dated 19th December 2016, namely “Percorso formativo per accedere alle figure professionali di Allievo Ufficiale di Coperta e Allievo Ufficiale di Macchina”.
Particularly, the course furnishes the following competencies, listed in the Attachment I of the above-mentioned decree, for Deck Officer Cadets:
C.1: Knowledge of the ship systems of control and manoeuvrability;
C.2: Optimization of the ship propulsive performance;
C.3: Effects of the displacement, draft, trim, speed and depth on the ship’s manoeuvrability;
C.4: Effects of wind and current on the ship’s manoeuvrability, squat effect in shallow water;
C.5: Turning curves and stopping distance;
C.6: Ship anchoring and mooring.

Further details about the acquired competencies are furnished in the extended version of the programme.

Teaching Methods

Frontal lessons, discussion of case studies, laboratory simulations.

Textbooks

The teaching material consists of:
- - Reference books in Italian and English;
- - Technical Rules in English;
- - Lecture notes of all lessons

Learning assessment

The exam consists of verifying the achievement of the previously defined educational goals, by an oral examination during which students shall discuss several plant schemes of existing ships, to evaluate the autonomous capacity of reading and comprehension.
