Welcome to the website where you can pass online the CES test on the subject «Heavy Weather 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.
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 «Heavy Weather Navigation». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Heavy Weather 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 a vessel navigating in heavy weather should have a good understanding of seamanship, navigation, and meteorology. They should also be familiar with all safety procedures onboard and have experience with the equipment onboard, including radars, gyrocompasses, and other navigational instruments.
In addition, the officer should be able to assess wind strength and direction, wave height and period, and other weather parameters that could affect the safety and efficiency of the vessel’s operation. They should also know how to properly use and configure automatic ship management systems to deal with adverse weather conditions. It is important to note that navigating a vessel in heavy weather requires not only knowledge and experience but also good physical fitness and stress resistance to make quick and correct decisions in critical situations.
On this site Crew Evaluation System Test on the subject «Heavy Weather Navigation» contains 78 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.
