Il corso fornisce una generale consapevolezza delle procedure pertinenti alla navigazione marittima in termini di pianificazione della traversata e tenuta della guardia. Esso riguarda le competenze 1.1, 1.2, 1.3, 1.4, 1.5 del IMO Model Course for Master and Chief Mate
The course offers a throughout understanding of the procedures that are relevant for the maritime navigation: a theoretical part allows to focus on the physics, geodesy and astronomy items related to navigation, while an operational part will focus on the methods that are necessary to carry out a reliable voyage planning and a correct execution, taking into account the use of nautical charts and publications, ship's routeing and ship's reporting systems. The position fixing will be analysed both in terms of coastal and celestial navigation considering the support provided by proper Aids to Navigation and the use and control of traditional instruments such as the magnetic and gyro compass and the marine sextant. The IAMSAR procedures are also taken into account.
The course offers a thorough understanding of the procedures that are relevant for the maritime navigation: a theoretical part allows to focus on geodesy, cartography, astronomy items related to navigation and statistical approach to the measurements. An operational part will focus on the methods that are necessary to carry out a reliable voyage planning and a correct execution in any condition, taking into account the use of nautical charts and publications, ship's routeing and ship's reporting systems. The position fixing will be analysed both in terms of coastal and celestial navigation considering the support provided by proper Aids to Navigation and the use and control of traditional instruments such as the magnetic and gyro compass and the marine sextant. The IAMSAR procedures are also taken into account.
Il corso mira a fornire gran parte dei risultati di apprendimento richiesti dalla Convenzione STCW Table A-II/2 “Specification of minimum standard of competence for masters and chief mates on ships of 500 gross tonnage or more”, funzione: Navigazione a livello direttivo.
Alla fine del corso gli studenti devono essere in grado di:
Applicare i metodi più adeguati per una affidabile pianificazione della traversata, nel rispetto delle normative internazionali in ogni condizione
Applicare le corrette procedure per una tenuta della guardia sicura, nel rispetto delle normative internazionali in ogni condizione
Essere consapevoli del funzionamento e dei limiti operativi della strumentazione di navigazione tradizionale in ogni condizione
Rispondere alle emergenze in termini di SAR

L’esame è orale ma viene richiesta agli studenti l’esecuzione preventiva di una breve trattazione scritta relativa al posizionamento astronomico con le tavole a soluzione diretta; questa viene assegnata direttamente agli studenti che si candidano all’esame via Aulaweb
La valutazione si basa in massima parte sull’esame orale, per il quale si attende la dimostrazione di una completa consapevolezza degli argomenti del corso in termini sia tecnici sia in relazione alle normative internazionali. Il corretto utilizzo del lessico appropriato è elemento di valutazione.
La tesina è importante per la valutazione della parte di astronomia nautica in termini di applicazione degli schemi e delle procedure di calcolo.
