Main Propulsion, Turbines, Boilers. Test 5

At what time should the duty engineer perform his evening UMS rounds?

As soon as all personnel have left the engine room after completion of their daily routines.
Anytime before midnight.
At any time, provided he is confident that the engine room will operate in a safe and efficient manner for the period it will be left unattended.
Anytime after midnight.

The revolutions on the turbocharger have increased during the night with unmanned engine. Could this be caused by:

The viscosity of the fuel is to high.
Poor combustion due to malfunction of fuel valves.
We have favourable winds and current.
The current and wind are holding the vessel back.

Before engaging the Turning Gear, precautions should be taken to:

Close the inlet and outlet valves for cooling water
Transfer M/E control from control room to emergency control console of engine
Shut off the starting air supply and open the indicator cocks
Open the indicator cocks and open the starting air supply

Why is it important to check the timing on the cylinder oil lubricators?

To avoid high temperature in the combustion chamber.
To avoid excess lubrication.
To get the right amount of oil into the cylinder.
To get the oil into the cylinder when the piston is in the right position.

With the compensating needle screw of a Woodward regulator is closed, what will happen when the load is changing?

Woodward regulator will regulate very fast
Woodward regulator will regulate normally
Woodward regulator will regulate very slowly
Woodward regulator will not regulate at all

Why do we use cylinder oil?

To neutralize the sulfur and get a lubricating oil film between piston rings and liner.
To avoid blowby.
To get a lubricating oil film between piston rings and liner.
To neutralize the sulfur in the fuel.

The water cooling space on the turbocharger is damaged and you have no spares. The cooling water must be closed. Which steps would you take to ensure least possible damage?

Run the engine at a lower speed
Dismantle the rotor and assemble the sealing plate
Make no modifications, but tell the duty engineer to pay special attention for abnormalities
Cool the turbocharger by means of air.

A 2 stroke engine is usually equipped with an auxiliary blower fan, which is supposed to be used:

during manoeuvre and manoeuvre speed condition (arrival and departure)
during continuously reduced speed under a longer sea voyage.
continuously, together with the turbochargers to ensure enough air to the engine during full speed running.
during a scavenging fire, to help put out the fire.

Spray painting has been carried out in the engine room while the engine was running. The turbocharger was not protected during the work.This could be the reason for:

The revolutions on the turbocharger are higher than normal.
The revolution of the turbocharger lower than normal.
Scavenging air pressure is higher than normal.
Exhaust gas temperatures are higher than normal.
