Welcome to the website where you can find answers for the CES test on the subject «Deck Management Navigation NA». This site will help you as a marine specialist improve your knowledge with the help of open information, where you can find questions as well as answers for them. CES based on practical information and marine specialists experience.

CES tests developed for evaluating seaman basic knowledge by Seagull Company (rebranded as «OTG»), is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW.

  • Version: 6.0.0.
  • Test type: STCW.
  • Department: Deck.
  • Level: Management.
  • Test type: any.
  • Area: Navigation – NA.

CES tests have proven themselves as good tools for the selection and recruitment process, as well as advancing the level of knowledge of the current officers and crew. Ocean Technologies Group use various subjects for question creation, which includes:

  • Crowd and Crisis Management;
  • Integrated Navigation System (INS);
  • Ballast water management;
  • Handling and Stowage;
  • Vessel operation management and safety;
  • Marine engineering;
  • Maintenance and repair, etc.

«Navigation» subject includes theoretical and practical information about safety working with electrical equipment. Knowledge of this information directly shows employee’s competence who holds a relevant post on a vessel. Vessel navigation refers to the process of directing and controlling the movement of a ship or boat from one location to another. It involves the use of charts, instruments, and various navigational aids such as GPS, radar, and sonar to ensure safe and efficient travel. Navigation also includes adherence to international maritime laws and regulations to prevent accidents and protect the environment.

This page contains answers to Seagull CES (Crew Evaluation System) test about Deck Management Navigation NA, and serve as a database of questions and answers, using which seafarer can prepare to exams for getting certificate of competence, or just to challenge yourself with knowledge in this theme.
