The bridge Officer of the Watch (OOW) is plotting the ship’s position in the chartroom, when the ship is in collision with a fishing vessel. Why would the OOW be held responsible for the collision?

Under the Rules a proper lookout should be maintained at all times and by all available means.

If the OOW is busy with the safe navigation of the ship he should have exhibited the “Not under Command” signals and made other ships keep clear.

If risk of Collision existed, the fishing boat should have contacted the larger ship over the VHF before the collision took place.

Under the Rules the fishing vessel should have kept clear of larger vessels and the OOW would not be responsible.

Induced magnetism.

A tug is moving towards the bow of the ship to make fast and is in the vicinity of the ship’s shoulder, as illustrated. What specific danger should be considered when making this approach to the bow?

The positive pressure field at the ships bow may repel the tug and make the connection very difficult to establish.

All of the alternative answers.

The stern of the tug may be sucked in towards the bow and also suffer a reduction in the positive GM, making it very unstable.

The tug may be turned across the bow of the ship and also suffer a lose of stability with a danger of being turned over if touched by the ship.

Similar distance to deep water.

A greater distance.

About 1,5 nautical miles.

A shorter distance.

Why should a Ground Stabilised True Motion radar display not be used for anti-collision purposes?

True motion does not provide the collision risk of targets as only true vectors are available.

The true vector can never give an indication of collision risk with another ship.

The “aspect” of the target is confused, so the Regulations for Preventing Collisions cannot be accurately applied.

Because this display is only ever used for navigation.

Calculation 3 is correct.

Calculation 1 is correct.

Calculation 4 is correct.

Calculation 2 is correct.

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?

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. The other vessel is being overtaken and is therefore obliged to keep out of the way by rule 13.

I will keep out of her way. I am the overtaking vessel and am obliged to keep clear under rule 13.

What letter is represented by this flag and what is it’s meaning when displayed by a vessel in port?

W – All persons should report onboard as the vessel is about to proceed to sea.

S – I am operating astern propulsion.

P – I require a pilot.

What could be the reason for the magnetic compass to swing through large angles when the ship is rolling in a seaway?

The heeling error magnets are upside down and/or not in the correct position.

The Coefficient B determined by the Compass Corrector at the last dry-dock was not correctly calculated.

The error due to deviation is large for that ships heading.

The induced magnetism from the earth’s magnetic field is very strong in that area.

When a ship is lying at anchor in a tidal area using both forward anchors, to what particular aspect should the officer of the watch be paying special attention?

The two anchors will restrict the ships swing with the tide and the ship may not lie to the prevailing current and wind.

The tension on both cables should be similar, to avoid one dragging and all the weight of the ship remaining on the other anchor only.

When the ship swings to the tide the direction of swing should be controlled to avoid the anchor cables becoming wrapped round each other.

The ship will become controlled by the tide and the wind will not be allowed to have any effect on the direction the ship lies at anchor.

What actions should the Officer of the Watch take when the ship’s steering gear fails?

Display the NUC signal and consider stopping the engines.

Request the engine room to check the steering gear.

All of the suggested answers.

Call the Master and advise him of the situation.

Yes, a ship often steers better if trimmed by the bow.

No, the ship will have the same steering ability and is unaffected by trim.

No, it is usually best to be on an even keel and have no trim at all.

Yes, the ship often steers better if trimmed by the stern.

The density of the water.

There should be no error with a properly working echo sounder.

Shallow water effects.

The strength of the tide and current in the river.

Two ships travelling in opposite directions are to pass each other in a narrow river, as illustrated. Explain what is likely to happen as they pass each other?

Due to interaction, the bows will attract each other as they approach, then they will repel each other alongside and as they pass clear, the sterns will be attracted.

Due to interaction, the bows will repel each other, and then when alongside each other the two ships will be sucked together and finally the sterns will be repelled as they start to pass clear.

As they approach, rudder should be applied quickly to avoid sheering into the path of each other. Then as they are alongside they will be attracted and finally repel each other as they pass clear.

There will be very little effect between the two ships as they pass.

You are proceeding up a river, with berths on both banks. You see this flag hoist on a vessel moored on a berth ahead. What does it mean?

You should proceed at slow speed when passing me.

Caution! I have an anchor down.

This vessel is sighted ahead and slightly to port. What is her situation? What will you do?

This is a vessel engaged in fishing vessel, with her nets fast on a obstruction. I will keep out of the way by rule 18 of the International Collision Regulations.

This is a vessel not under command at anchor.

This is a vessel aground. She appears to have been headed to starboard of my track and I will therefore alter course to port, passing under her stern.

This vessel is aground. I will navigate with extreme caution given the nature of the hazard.

How can an ARPA assist the ship to steer a suitable course to make good the entrance to a channel?

The «Navigation (NA) Operational Level» subject covers both theoretical and practical knowledge regarding safety when working with electrical equipment. Mastery of this information is a key indicator of an employee's competence in their specific role on a vessel. As a 3rd officer responsible for navigation duties, your primary tasks include assisting senior officers in planning the ship’s voyage by calculating safe passage routes, preparing navigation charts, and monitoring weather conditions. You are also responsible for conducting regular safety checks on all life-saving equipment to ensure it is in good working order, as well as operating and maintaining navigational equipment like radar, GPS, and compasses to ensure they are functioning correctly.
