Welcome to the website where you can pass online the CES CBT CD-0601 test on the subject «Vapor Control Systems». 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 «Vapor Control Systems». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Vapor Control Systems» subject includes theoretical and practical information about advanced training for work on any type of vessel. This comprehensive course covers the design, installation and operation of vapor control systems, ensuring that sailors understand their crucial role in maintaining vessel safety and environmental compliance. The theoretical aspect involves learning about the principles of vapor control, the different types of vapor control systems, their applications and the regulatory requirements governing their use. Practical training involves hands-on exercises in inspecting and maintaining vapor control systems, troubleshooting common issues and performing maintenance tasks to ensure optimal performance. The course also covers emergency procedures for vapor control system failures, emphasizing the importance of quick response and effective problem-solving. Additionally, seafarers learn about the integration of vapor control systems with other vessel systems, such as cargo handling and ventilation, to create a cohesive safety strategy. The training is designed to equip seamen with the knowledge and skills necessary to handle vapor control systems confidently, thereby contributing to the overall safety and efficiency of marine operations.
On this site Crew Evaluation System Test on the subject «Vapor Control Systems» contains 19 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.

After a dock automatic shutdown, it is OK to resume transfer operations:
When the reason for the shutdown is known and corrected and the information has been passed on to the dispatcher.
When dock operations appear to be back to normal.
When the dispatcher gives the OK.
As the cargo tank space fills with liquid, the vapors:
Vent out of the tank by a vent stack or into the dock collection system.
Build up in the tank.
Collect in the barge’s collection system.
Vent out through the vent stack into the air.
Barge vent piping is used to direct the tank vapors into a common manifold on the barge deck.
True.
False.
Carbon bed absorption is one method that may be used to reclaim carbon vapors once they are collected at the dock facility.
True.
False.
High initial loading rates and improper gauging techniques can generate … that can cause an explosion if there are vapors in the surrounding area in the explosive range.
Static electricity.
Excessive pressure.
Incorrect ullage readings.
If for any reason, the transfer operation goes out of control, creating a serious emergency, what should you do first?
Stop the transfer.
Contact the dispatcher.
Run for help.
In the US, vapor control regulations are under the jurisdiction of:
USCG.
EPA.
IMO.
SOCP.
One reason for over-pressurization of the vapor lines is:
Blocked with condensation.
Filled with air.
Leaking.
Over-pressurization occurs when:
The vapors leave the cargo tank more slowly than the liquid enters.
The vapor pressure in the cargo tanks or dock facilities builds to excessive levels due to a slow loading rate.
The vapors leave the cargo tank more quickly than the liquid enters.
Vapors that vent directly into the air pose hazards to:
Personnel and the environment.
Personnel.
The environment.
What can happen if the cargo and vapor lines are misconnected?
The transfer will load slower.
The tank may be top-loaded with liquid vapor from the vapor collection piping.
You will have more time to perform your other tankerman duties.
What is a function of the vapor vent stack?
Allows air to enter the tank and fill the space left after the cargo leaves the compartment.
Helps prevent mistakes in connecting the cargo line to the vapor header.
Helps prevent the build-up and uncontrolled release of static electricity.
Relieve vapor pressure at the same rate as the maximum loading rate.
What is the primary reason for adding vapor control systems to barges?
Reduce harmful emissions.
Improve barge design.
Increase barge efficiency.
Meet regulatory requirements.
When the liquid level in the cargo tank rises, the vapors are forced into the barge’s collection piping. This is referred to as:
Inverse pressure.
Negative pressure.
Positive pressure.
Which of these factors affect the flow of vapor through your barge’s collection piping?
Loading rate.
Pipe diameter.
Vapor density.
Which of these statements about normal cargo transfer operations is true?
Stop the cargo flow when the liquid approaches the bottom edge of the prescribed top-off in the last tank.
Disconnect the hoses and power cable after disconnecting the bonding cable.
Observe the cargo liquid level by opening the tank hatch.
Slow the cargo flow when the cargo level reaches the red color on the gauge stick.
Which of these steps are NOT completed as part of a normal transfer operation?
Ensure the barge and dock vapor header valves are open.
Monitor the transfer rate.
Maintain communication with the boat.
Slow the cargo flow.
Which of these tasks do you need to do when completing your final barge preparation and inspection for a cargo transfer?
Connect the dock’s power supply for the high level alarms.
Ensure that the barges vapor system is properly alarmed.
Inspect all sight glasses for condensation or damage.
Inspect and test the barge PV to determine that it operates freely.
Which of these tasks is NOT a transfer preparation task?
Assist with tank inspection.
Observe the cargo liquid level.
Complete transfer connections.
Discuss upcoming transfer.
