Maintenance and repair, etc.
Current test contains Seagull CES questions on the subject «Engine, Support level». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Engine, Support level» 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. On board a vessel, the technical maintenance of the engine is typically managed by a team of dedicated marine engineers or engine crew members. These professionals are responsible for ensuring the engine’s proper functioning, conducting routine inspections, and performing necessary repairs or adjustments. Maintaining an optimal engine support level is crucial for safe and efficient maritime operations, as it helps prevent breakdowns at sea and ensures compliance with industry regulations, ultimately safeguarding both the vessel and its crew.
On this site Crew Evaluation System Test on the subject «Engine, Support level» contains 230 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.

From the midpoint of the weight.
From the base of the derrick or crane.
What is the anticipated rolling period of a ship with a large initial Transverse Metacentric Height (GM) and would there be any associated dangers to consider?
Long slow rolling period with no significant dangers.
Moderate rolling period with increased stability.
Short sharp period of roll associated with breaking lashings and shifting cargo.
No rolling period as the ship remains stable.
The Ziegler-Nichols method is used in control engineering when setting up the system. Which of the system components given in the options would this method be applied to during initial set up?
PID controller for tuning.
Actuator for calibration.
Sensor for adjustment.
Feedback loop for optimization.
With the set point at the actual desired value, a temperature control system is giving an unacceptably large offset (difference between set point and measured value) on high load resulting in a low system temperature. Which of the actions given in the options should be taken to reduce this effect and therefore achieve closer control of the temperature?
Increase the integral time of the controller.
Reduce the width of the proportional band for the controller.
Decrease the gain of the controller.
Add a delay to the control response.
The refrigeration system for the ship’s provisions consists of a number of cold rooms served by a central refrigeration system. The evaporator coils for the vegetable room are found to be frosting up even though the room is down to temperature and the liquid line valve has closed. Select, from the options given, the automatic control component which is likely to be malfunctioning and so cause this condition.
Back pressure control valve.
Expansion valve.
Thermostat.
Liquid line solenoid valve.
As part of a survey of a main steam boiler it is necessary to check the condition of the steam drum. What would be the preferred method for checking drum shell thickness in such a situation?
Use ultrasound equipment.
Visual inspection with a boroscope.
Magnetic particle testing.
Hammer testing for soundness.
An accumulation test may be necessary for a steam boiler following repairs or modifications. Which of the given options does the accumulation test check?
The efficiency of the boiler’s heat exchange.
The integrity of the boiler’s structure.
The capacity of the safety valve to relieve pressure.
The performance of the feedwater system.
During «dry lay up» of a main water tube boiler it is necessary to maintain a dry, low humidity environment in the water spaces. Which of the chemicals given in the options would best achieve this condition?
Silica gel.
Sodium hydroxide.
Calcium carbonate.
Ammonium sulfate.
Chemical boiling out is one method that is used for cleaning the waterside of a steam boiler. Select from the given options the likely circumstances under which this procedure would be considered necessary?
Contamination of the boiler water by oil.
Regular maintenance after a specified period.
Scaling due to hard water deposits.
Routine cleaning before a survey.
A deadweight tester is used to check and calibrate a pressure gauge. The tester consists of a hydraulic pump and a hydraulic chamber and balance weight system. After completing the calibration of the pressure gauge, the hydraulic pressure should be relieved before removing the weights. Select, from the options given, the main reason for this requirement.
To protect the piston in the hydraulic system from possible impact damage as it may reach the end of its stroke.
To ensure accurate readings on the pressure gauge.
To prevent leakage of hydraulic fluid.
To allow the system to cool down before disassembly.
Vibration analysis is often used as a conditioning monitoring tool onboard ship as part of the approved planned maintenance system. Many vibration measuring instruments are fitted with a harmonic filter/analyser. How would these filters normally be used during vibration measurement on a centrifugal pump?
To measure the overall vibration level of the pump.
To isolate a single frequency of vibration associated with one of the pump’s components.
To eliminate all vibrations above a certain threshold.
To average the vibration readings over time.
Compressed air for instrument and control purposes needs to be of high quality. In order to condition the air, filter modules are usually fitted to remove the contaminants. If there is evidence of oil carry over to the final elements in the instrumentation air system, what is the most likely cause?
The coalescer module is saturated and requires renewal.
The air compressor is malfunctioning.
The final filter is clogged.
The system pressure is too low.
The recognised definition of High Voltage equipment is anything that operates at over which of the following levels?
500 Volts ac or 750 Volts dc.
1 000 Volts ac or 1 500 Volts dc.
1 200 Volts ac or 1 800 Volts dc.
600 Volts ac or 900 Volts dc.
High Voltage (HV) cables are smaller than low voltage cables for a given power rating. Why is this?
The HV cable carries a smaller current and therefore requires less copper.
The insulation required for HV cables is thinner.
HV cables are made from lighter materials.
HV cables operate at a higher temperature.
