Welcome to the website where you can pass online the CES test version 6.0.11 on the subject «Deck Operational LPG». 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: 6.0.11.
Test type: STCW.
Department: Deck.
Level: Operational.
Type: LPG tanker.
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 Operational LPG». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Deck Operational LPG» subject includes theoretical and practical information about advanced training for work on any type of vessel. This test evaluates theoretical knowledge and practical skills required for safe LPG handling on liquefied gas carriers. It covers key topics such as cargo operations, tank pressure management and emergency procedures specific to LPG vessels. Candidates will be assessed on their understanding of gas properties, hazards and relevant international regulations (IGC Code, SOLAS). Practical scenarios include simulating leak detection, valve operations and risk mitigation during loading/unloading. The test ensures compliance with STCW advanced training requirements for deck officers serving on LPG tankers. Questions may involve case studies on collision safety, inert gas systems and fire prevention in gas carrier operations. Successful completion certifies competency to work with LPG cargo on both fully refrigerated and semi-pressurized vessels. The assessment combines multiple-choice questions, diagrams and situational judgment tasks for comprehensive evaluation.
On this site Crew Evaluation System Test on the subject «Deck Operational LPG» contains 46 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 all 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!
