Parts of Rule 2?

A

“Responsibility”:

A) Nothing shall exonerate any vessel, the owner, or master of crew thereof, from consequence of any neglect to comply with the Rules or of the neglect of any precaution which may be required by the ordinary practise of seamen, or by the special circumstances of the case.

B) In complying with these Rules due regard shall be had to all dangers of navigation and collision and to any special circumstances, including the limitations of the vessels involved, which may make a departure from these Rules necessary to avoid immediate danger.

ie:

A) Nothing exonerates anyone from consequences of neglect to comply with rules, or neglecting precautions that may be required by ordinary practise, or by special circumstances.

B) In the interest of safety in an exceptional situation, Rule 2(b) gives us freedom to avoid a collision and minimise damage by departing from the rules if needed. Due regard shall be had to all dangers of navigation and collision and to any special circumstances, including limitations of vessels, which may require departure of rules.. etc

Q

Rule 5

A

Look-out

Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate to the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision.

MGN 315 (M) Keeping a safe navigational watch on merchant vessels

101
Q

Can full speed be a safe speed

A

Yes, even in restricted visibility, especially on the high seas, in most traffic separation schemes and on fairways that are considered fundamentally safe. Providing a vessel is using radar and AIS in the right way it can be a safe speed under most conditions.

102
Q

Rule 6

A

Safe Speed

Every vessel shall at all times proceed at a safe speed so that she can take proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and conditions.

103
Q

Which factors do you take into consideration when determining safe speed?

A

A) All vessel:
I) state of visibility
II) traffic density including the concentration of fishing vessels or any other vessels
III) manoeuvrability of the vessel with special reference to stopping distance and turning ability in the prevailing conditions
IV) at night, the presence of background light such as from shore lights or from back scatter of her own lights
V) state of wind, sea and current, and the proximity of navigational hazards
VI) draught in relation to the available depth of water

B) Additionally, by vessels with operational radar:
I) characteristics, efficiency and limitations of the Radar equipment
II) constraints imposed by the Radar range scale in use
III) effect on radar detection of the sea state, weather and other sources of interference
IV) possibility that small vessels , ice and other floating objects may not be detected by radar at an adequate range
V) number, location and movement of vessels detected by radar
VI) more exact assessment of the visibility that may be possible when radar is used to determine the range of vessels or other objects in the vicinity.

104
Q

Rule 7

A

Risk of Collision

A) Every vessel shall use all available means appropriate to the prevailing circumstances and conditions to determine if risk of collision exists. If there is any doubt such risk shall be deemed to exist.

i.e. sight, hearing, all available means/equipment on the bridge.

B) Proper use shall be made of radar equipment if fitted and operational, including long-range scanning and Radar plotting or equivalent systematic observation of detected objects.

C) Assumptions shall not be made on the basis of scanty information, especially scanty radar information.

D) In determining if risk of collision exists the following considerations shall be among those taken into account:

i) such risk shall be deemed to exist if the compass bearing of an approaching vessel does not appreciably change;
ii) such risk may sometimes exist even when an appreciable bearing change is evident, particularly when approaching a very large vessel or a tow or when approaching a vessel at close range.

105
Q

Which requirements have to be met to avoid a collision?

A
  • Actions to avoid collision have to be in accordance with rule 8
  • Be positive (easily seen and effective)
  • Made in ample time
  • Due regard to the observance of good seamanship
106
Q

What is a rule of thumb concerning the alteration of course as a means to avoid a collision?

A

Alterations of course should be readily apparent to another vessel observing visually or by radar, avoiding a succession of small alterations of course and/or speed.

107
Q

In which ways can you give way to another vessel?

A

Slow down (possibly come all the way off, or reverse means of propulsion), Parallel their course and allow them to pass at safe distance (effectiveness to be checked until the other vessel is finally passed and clear)

108
Q

Which obligation remains, even after giving way to another vessel?

A

Keep out of the way.

109
Q

Where is impeding mentioned in the Colregs?

A
  • Rule 9b, 9c and 9d
  • Rule 10i and 10j
  • Rule 18d (i)
110
Q

How do you define a fairway or narrow channel?

A

The OOW decides if he is sailing in a narrow channel or not. Factors taken into consideration are;

  • That you may be in a narrow channel based on buoyage
  • The width of the navigable fairway. (Navigable is a different concept for different types of vessels)
  • The draught and the manoeuvrability of the vessel are important with respect to a fairway

A traffic separation scheme is not a narrow channel and is subject to rule 10.

111
Q

A vessel sailing in a narrow channel gets hit by a vessel crossing the channel, what must he be able to prove?

A
  • That he was not able to leave the channel, due to his draught
  • that he could not slow down (i.e. because of a strong current or vessels following him).

NB: Rule 9 overrides rule 18

112
Q

Maximum angle at which to join or leave the traffic separation?

A

20 degrees

113
Q

Which vessels are exempted from complying with Rule 10?

A

k) A vessel restricted in her ability to manoeuvre when engaged in operation for the maintenance of safety of navigation in a traffic separation scheme, to the extent necessary to carry out the operation.

l) A vessel restricted in her ability to manoeuvre when engaged in operation for the laying, servicing or picking up of submarine cable, within a traffic separation scheme, to the extent necessary to carry out the operation.

114
Q

When may a vessel use inshore traffic zones?

A

Rule 10:

i) A vessel shall not use an inshore traffic zone when she can safely use the appropriate traffic lane within the adjacent traffic separation scheme. However, vessels of less than 20m in length, sailing vessels and vessels engaged in fishing may use the inshore traffic zone.

ii) A vessel may also use an inshore traffic zone when en route to or from a port, offshore installation or structure, pilot station or any other place situated within the inshore traffic zone, or to avoid immediate danger.

Summary:

  • Vessels less than 20m in length
  • Sailing vessels
  • Vessels engaged in fishing
  • Vessel en route to or from port, offshore installation or structure
  • Vessel en route to pilot station or or any other place situated within the inshore traffic zone
  • To avoid immediate danger
115
Q

When is a vessel deemed to be overtaking another vessel?

A

Rule 13 (b):

A vessel shall be deemed to be overtaking when coming up with another vessel from a direction more than 22.5 degrees a aft her beam, in such a position that at night she would be able to see only the stern light of that vessel but neither of her side lights.

116
Q

Rule 13

A

Overtaking

a) Not withstanding any rules contained in Part B, Sections i and ii, any vessel overtaking any other shall keep out of the way of the vessel being overtaken.

b) A vessel shall be deemed to be overtaking when coming up with another vessel from a direction more than 22.5 degrees a aft her beam, in such a position that at night she would be able to see only the stern light of that vessel but neither of her side lights.

c) When a vessel is in any doubt as to whether she is overtaking another, she shall assume that this is the case and act accordingly.

d) Any overtaking vessel shall not become a crossing vessel in any subsequent alterations of bearing or manoeuvres within the meaning of these rules - or relieve her of the duty of keeping clear of the overtaken vessel until she is finally past and clear.

Summary:

a) Keep out of way of a vertalen vessel

b) More than 22.5 degrees abaft beam and only seeing stern light not side lights

c) When in doubt, assume you are overtaking, act accordingly

d) Overtaking vessel never becomes crossing vessel subsequently, or relieve of duty to keep clear

233
Q

As a power driven vessel you are stopped in the water but underway and have a vessel crossing from your starboard beam, your engines are out of gear. Who has right of way?

A

She does, a power driven vessel which is stopped underway must, unless she is not under command, or RAM, keep out of the way of another vessel which approaches so as to involve risk of collision from any direction between right ahead and 22.5 degrees abaft the beam on her starboard side. The approaching ship must not be expected to take avoiding action. A vessel lying stopped with her engines ready for manoeuvre is not entitled to show any special lights or shapes to indicate that she is privileged and must comply with rules 14, 15, and 18.

234
Q

You are underway as a power driven vessel and have a NUC comes up from astern, who is give way?

A

NUC, Rule 13 overrides all other rules in section 1 and 2, therefore the NUC must keep clear.

235
Q

Name all power driven vessels, if risk of collision exists with these, what action do you take?

A
  • Tug and tow
  • Power driven
  • CBD

Avoid an alteration of course to port for a power driven vessel, thus alter to starboard, or slow down or stop.

236
Q

TSS, who should avoid impeding you as a power driven vessel?

A
  • Sailing vessels
  • Vessel less than 20 meters in length
  • Fishing vessel should not impede ALL vessels, not just power driven.
237
Q

In IRCPS it states that a power driven vessel shall not turn to port in which rules?

A

14, 15, and 17.

A

Fixed Red

240
Q

Does a dead reckon include leeway?

A

No, only speed through water and heading.

241
Q

Describe your recommendation for radar setup?

A

In order to use the radar for collision avoidance specifically, set up:

  • Relative motion: Own vessel will show no trail, this targets will show relative trails
  • North Up/Course Up: Both are gyro stabilised displays, as our own ships heading moves or changes, because our heading is stabilised to gyro, targets around us will not move around as we yaw. It allows ARPA the required 3 minutes of steady state tracking to give us accurate results.
  • Sea stabilised: fixed objects will show true vectors, as well as own vessel (if own vessel shows a vector then we are in true vectors settings). Course over ground (ground stabilised) is NOT heading, and heading we need to derive aspects and comply with COLREGS.
  • Relative trails: to help tel us quickly if risk of collision exists, relative trail effectively shows us OA of the WOA triangle to give us indication of risk of collision, but also tells us where the plot is coming from.
  • True Vectors: Best indication of aspect, by looking at the vector of the target and putting the EBL on the target, we can clearly see the aspect of the approaching target. Calculate carefully by using radar bearing scale. Giving us a good indication of the situation around us and an improved ability to apply rule 19.

A
  1. Vessels required to show sidelights when MAKING WAY are:
  • NUC
  • RAM
  • FISHING
  • TRAWLING

These vessels are Underway but NOT MAKING WAY if the side lights are off, EXCEPT:

  • FISHING
  • TRAWLING
  • RAM Underwater Ops

These may also be at anchor as well as stopped (with no anchor lights)

  1. Underway POSSIBLY making way with sidelights include:
  • PDV
  • PDV Tow
  • CBD
  • Sail
  • Pilot
  • Mine Clearance Vessels
244
Q

How can you establish that a vessels length is unknown vs. probably known vs. definitely known?

A

The following vessels length are PROBABLY known
when masthead lights are spotted:
- PDV (PDV less than 50m may exhibit 2 masthead lights not just the 1, PDV over 50 must show 2 masthead lights)
- RAM
- Vessels with just one light e.g Trawling vessel with one masthead light abaft and higher than the all-round green/red light (of over 50m in length shall be required to display)
- Trawler without a masthead light means probably over 20m but definitely under 50m

Definitely known:

Trawling vessel with one white masthead light is over 50m as per Rule 26.

The following vessels are length UNKNOWN (no mastheads):
- Trawler (if under 50m not required to display a masthead light)
- Fishing Vessel
- Pilot
- Sail
- NUC
- Any vessel from astern
