Do you think there is any reduction in the rudder lift force if the propeller is stopped?

No, the lift force is not effected by the propeller.

Yes, the lift force will be dramatically reduced.

The ship has a right-handed propeller and is swinging to starboard when the engines are slow ahead and the rudder is to starboard. The engines are stopped and the rate of swing rapidly slows down. How could the swing to starboard be maintained without the ship making much headway.

Astern on the engines will allow Transverse Thrust to continue the swing

By applying the rudder hard over to starboard and going ahead on the engines.

The only effective method is by using the bow thruster to push the bow to starboard.

Transverse Thrust will reduce the swing and therefore a kick ahead is necessary with full starboard helm applied.

Which of the alternative methods of using a tug when escorting your ship through narrow waters do you think is the most effective if you lose steering power?

Many modern large slow speed diesel engines used for main propulsion operate with a so called constant pressure turbocharging system. What is meant by constant pressure when used to describe such a turbocharging system?

Pressure variations in the scavenge air supply are avoided by supplementing the air supply with air from the auxiliary blowers so keeping a constant pressure across the load and speed range.

Pressure variations at the turbocharger inlet are damped out due to the large volume of the exhaust receiver and the short lengths of pipe from individual cylinders.

The exhaust pipes from groups of three cylinders are joined together before entry into the turbocharger so that the exhaust pulses from each cylinder cancel each other giving a constant inlet pressure.

The exhaust gas pressure is maintained constant by using a bypass waste gate to dump excess pressure at high engine loads.

Before commencement of any work aloft, you should carry out risk assessment of the worktask. What kind of extra personal protective equipment is required as a minimum to carry out the work?

Carry out the work without extra personal protective as long as no one sees what's going on

As long as someone is supporting the ladder there is no need for extra personal protective equipment
