<![CDATA[Radar is one of the most important navigational aids for the officer of the watch, particularly at night, in restricted visibility, and in congested or narrow waters, but its value depends on correct operation, interpretation, and maintenance. This study examines the problems in the operation of radar during navigation on the KM Oriental Galaxy and identifies measures to optimise its use. A qualitative descriptive design was used, with data collected through direct observation, informal interviews with the Second Officer, the Third Officer, two helmsmen on watch, and a deck cadet, and documentation, including the planned maintenance records, during the authors’ 12-month sea practice. The results show that radar operation on board did not yet fully meet the applicable operating procedures. The problems identified were ineffective detection of targets and navigational hazards, deteriorating magnetron performance, blind and shadow sectors in the radar coverage, and spurious and false echoes that did not correspond to real objects. These problems were related to the crew’s limited knowledge of radar settings, display modes, and limitations, to insufficient attention by the officers to their responsibility for navigational equipment, and to routine maintenance that was not carried out on schedule, as shown by overdue items in the planned maintenance system. Technical guidance was given to the crew on radar settings, interpretation of the display, emergency handling, and basic maintenance. Training of officers and ratings in radar operation and its limitations, maintenance in accordance with the manufacturer’s instructions and the planned maintenance system, recording of blind sectors, and prompt company support for spare parts and repairs are recommended.]]>
