Join Our Telegram (Seaman Community)

Welcome to the website where you can pass online the CES test on the subject «Deck Management Navigation». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. 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.
  • Vessel 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.

Current test contains Seagull CES questions on the subject «Deck Management Navigation». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.

«Navigation» subject includes theoretical and practical information about advanced training for work on any type of vessel. Knowledge of this information directly shows employee’s competence who holds a relevant post on a vessel. An officer on navigation duty on a vessel is responsible for various tasks related to the safe and efficient navigation of the ship. Some of their key responsibilities include monitoring and maintaining the vessel’s position and course using navigational instruments such as GPS, charts, radar, and compasses. Also planning and executing the vessel’s route, taking into consideration factors such as weather conditions, traffic separation schemes, navigational hazards, and port regulations and etc.

On this site Crew Evaluation System Test on the subject «Deck Management Navigation» contains 44 questions you need to answer with no possibility to go back to previous question. Therefore, we recommend carefully reading each question and making decision with no hurry. In case you have some difficulty answering, you have also possibility to request a hint.

Next question
Code: WfsSpl5A A tug is connected to the bow of a vessel. Will the force exerted by it be the same at any ahead speed?

Next question
Code: vyDsfFJP You are a Senior Officer of the Watch on vessel “A” and are passing through the Straits of Gibraltar. The vessel’s speed is 18 knots and your vessel is overtaking several other vessels, when the visibility reduces down to about 2 nm. What aspects would you consider when establishing a “safe speed” for your vessel?

Traffic in Straits of Gibraltar

Safe speed should be where the vessel can come to a stop within the visible range.
Deciding safe speed consider: 2 miles visibility; traffic density; manoeuvring of vessel; effectiveness of navigational equipment (ARPA etc); state of sea and currents and navigational hazards.
A safe speed is where a vessel can take proper and effective action to avoid collision and be stopped within an appropriate distance.
Adjust my track to follow Route 1 or 2 illustrated and reduce speed down to half speed, approximately 8 knots.
