Current test contains Seagull CES questions on the subject «6.0 Deck Management LNG Tanker». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Deck Management LNG Tanker» subject includes theoretical and practical information about advanced training for work on any type of vessel. This test assesses knowledge and skills required for advanced operations on LNG carriers. It covers critical topics such as cargo handling, gas containment systems and emergency procedures specific to liquefied natural gas transport. Candidates must demonstrate proficiency in deck operations, safety protocols and risk management related to LNG hazards. Practical simulations include real-world scenarios like leak response, vapor dispersion control and emergency shutdown drills. The exam evaluates understanding of LNG properties, including boil-off gas management, pressure control, and flammability risks. Compliance with international regulations (IGC Code, SOLAS) and environmental protection measures is a key component of the assessment. Crisis management, crew coordination and decision-making under pressure are tested to ensure operational readiness. Successful candidates receive certification qualifying them for advanced roles on LNG tankers and other gas carriers.

A deep draught vessel sailing in a very narrow channel can develop a sudden sheer as it slows down. What could be the cause of this?
The large volume of water dragged behind the vessel continues to move forward and cause a strong turning moment on the stern of the vessel.
The shallow water reduces the effectiveness of the rudder and when the vessel stops any applied rudder will become suddenly more effective.
The wind pressure on the superstructure increases as the vessel slows down.
The vessel’s propeller wash becomes less effective at low speeds.
Why does a ship with ahead or astern speed have a small lateral or sideways movement when turning?
The hydrodynamics of the hull cause a drift angle to be produced, which is not in the fore and aft line of the vessel.
The ship moves laterally because it has a single hull.
The rudder creates a sideways force that pushes the ship off course.
The wind pressure on the hull causes it to drift sideways.
What radar device assists in the detection and location of a survival craft?
SART beacon.
A personal locator beacon.

When dealing with the LNG cargoes, the main information that can be obtained from a Mollier diagram includes:
Information about the exact values of the pressure, density, specific volume and dryness fraction of the vapour when both the enthalpy and temperature are known.

Information about the heat capacity of the liquid.
Information about the boiling point of the LNG at different pressures.
You are on a power-driven vessel underway in open water. This vessel is sighted directly ahead. The distance is closing slowly. What action will you take under the International Collision Regulations and why?
I will keep out of her way. I am the overtaking vessel and am obliged to keep clear under rule 13.
The vessel is on a steady bearing and the distance is closing. I will therefore take avoiding action, altering course to starboard and sounding one short blast under rules 14 and 16.
I will maintain my course and speed as I have the right of way.
I will alter course to port to pass ahead of the other vessel.
Under most circumstances, how will communication be carried out between a ship and a SAR helicopter?
On VHF Ch 16.
On 121,5 MHz.
On HF frequencies.
On VHF Ch 13.
As per the IMDG Code, “Marine Pollutant” is defined as:

A substance that is hazardous to the environment.
Substances, materials and articles shall be stowed as indicated in the Dangerous Goods List of the IMDG Code, in accordance with a series of stowage categories, which are designated as:
