Welcome to the website where you can pass online the CES test for seamans on the subject «Deck, Support, LNG». 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: 5.2.8.
- Test type: STCW.
- Department: Deck.

Current test contains Seagull CES questions on the subject «Deck, Support, LNG». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Support» 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 Liquefied Natural Gas Carrier. Individuals in the Deck Support department on an LNG (Liquefied Natural Gas) Carrier are responsible for various critical tasks related to the safe and efficient functioning of the vessel. Their duties include assisting in the handling of LNG cargo, ensuring proper securing and monitoring during loading and unloading operations. Deck Support personnel on an LNG Carrier also play a key role in safety drills, emergency response procedures, and contribute to the overall maintenance and cleanliness of the deck area, adhering to stringent safety standards specific to LNG transportation.
On this site Crew Evaluation System Test on the subject «Deck, Support, LNG» contains 61 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.
The test includes three modes. In the Training mode, you go through 60 questions with the option to take a hint, while in the Exam mode, this option is not available. We have also developed another mode – Wild, where you can answer all the questions available in the test at once. Enjoy!
