According to the International Labour Organisation, how often should lifting appliances and items of loose gear be thoroughly inspected by a competent person?
Annually.
Biannually.
Every 5 years.
Every 6 years.
Which of the options best describes how a “Balanced Rudder” is constructed?
There is equal rudder area forward and aft of the turning axis, the turning axis being at the geometrical centre of the rudder area.
The rudder has an additional flap attached to the trailing edge to improve rudder efficiency.
Part of the rudder area is forward of the turning axis, therefore reducing the load on the steering motor.
The rudder is operated by two steering motors providing equal amounts of power to the rudder.
Your watchkeeper has just informed you that the vessel has collided with a sailing vessel. What action should be taken?
Alarm the rescue centre and commerce searching for survivors.
Tell the watchkeeper to sort out the problem.
Tell the watchkeeper to proceed on passage.

How are the effects of squat seen on a moving vessel?
There will be a reduction of the vessel’s underkeel clearance and a possible change of trim.
There will be an increase in the vessels draught while moving through the water.
Heel can result on a vessel with a large block coefficient and a speed reduction.
There will be a change of draught and a reduction in the speed.
Your vessel has been involved in a minor collision. What will your actions be following the collision?
All of the answers are correct.
Make sure your vessel + crew are safe and then offer your assistance to the other vessel.
Call the Company DPO and the local state if close to the coast.
Continue the voyage to your destination monitoring for water ingress.
Would the indicated ground speed be suitable when berthing a large vessel?
The approach speed is essential to maintain steerage when coming alongside.
The speed requirements are decided by the pilot and should not be the concern of the OOW.
The approach speed is way too fast, even for a vessel in ballast.
The indicated speed would be a normal speed approaching a berth.
Your vessel is involved in a collision with another vessel. What should you as Master tell the Master on the other vessel?
Explain your actions prior to the collision and request details of actions taken by the other vessel which resulted in the collision.
Name of vessel; IMO number; Port of registry; Port of destination of your vessel.
There should be no communication with the other vessel.
That their actions were totally wrong and it is their fault.

Having a tug attached to a fairlead close to the pivot point.
Having a tug attached to the stern centre lead on a tug line.
When planning to cross an ocean, is it always best to use great circle sailing?
Yes – because it is the easiest sailing to compute and then follow.
No – because there could be environmental or regulatory restrictions.
No – because a Mercator course is more efficient, less distance and easier to follow.
Yes – because an ECDIS in track control will do the computation and steer the route.
According to the International Labour Organisation, how often should lifting appliances be re-tested?
Annually.
2 1/2 years.
2 years.
5 years.
The ship is approaching shallow water where the Under Keel Clearance will reduce to about 0,25 of the ship’s draught. Which of the following answers most accurately summarizes the aspects to be considered when deciding a suitable speed?
A reduced ability to stop the vessel and maintain steerage.
A further reduction of underkeel clearance and possible changes of the ship’s trim.
Touching the bottom if there is any swell and causing damage due to the wake or wash of the vessel.
All of the suggested answers.
A tug is connected to the bow of a vessel. Will the force exerted by it be the same at any ahead speed?
No, when the ahead speed of the ship increases the force exerted by the tug will also increase.
No, on the bow the tug uses power to run with the vessel, which reduces the available power on the towline.
Yes, because when moving ahead a tug can use indirect towing methods.
Yes, the force would normally be expected to be the same at any speed of the ship.
The International Convention for the Safety of Life at Sea (SOLAS) regulations, Chapter 5, deals with the Safety of Navigation and applies to which vessels?

The Worldwide Maritime Mutual Assistance Programme (WMMAP).
Whilst sailing through a narrow coastal passage, an ECDIS alarm indicates that number 1 GPS HDOP value is outside set limits. What should happen on the bridge?
The receiver should be checked and the vessel’s position confirmed by other means.
Number 2 GPS should be selected as the primary receiver and the number 1 GPS switched off.
The watchkeeper should call the master and then adjust the limit so that the alarm is removed.
The ECDIS should be switched off as it will now be in DR mode and misleading to the bridge team.
You are a Senior Officer of the Watch on vessel “A” and are passing through the Straits of Gibraltar. The vessel’s speed is 18 knots and your vessel is overtaking several other vessels, when the visibility reduces down to about 2 nm. What aspects would you consider when establishing a “safe speed” for your vessel?
The receiver should be checked and the vessel’s position confirmed by other means.
Number 2 GPS should be selected as the primary receiver and the number 1 GPS switched off.
The watchkeeper should call the master and then adjust the limit so that the alarm is removed.
The ECDIS should be switched off as it will now be in DR mode and misleading to the bridge team.
You are a Senior Officer of the Watch on vessel “A” and are passing through the Straits of Gibraltar. The vessel’s speed is 18 knots and your vessel is overtaking several other vessels, when the visibility reduces down to about 2 nm. What aspects would you consider when establishing a “safe speed” for your vessel?
Deciding safe speed consider: 2 miles visibility; traffic density; manoeuvring of vessel; effectiveness of navigational equipment (ARPA etc); state of sea and currents and navigational hazards.
Safe speed should be where the vessel can come to a stop within the visible range.
A safe speed is where a vessel can take proper and effective action to avoid collision and be stopped within an appropriate distance.
Adjust my track to follow Route 1 or 2 illustrated and reduce speed down to half speed, approximately 8 knots.
