21

• 2a Anyone must obey the Rules and act in good seamanship. In normal circumstances you are not allowed to depart from the Rules

• 2b You may (must) only depart from the Rules in certain circumstances if it is absolutely necessairy to avoid immediate danger

Rule 2 Responsibility

Examples 2a Applying ordinary seamanship

– Anchors, engine not ready to manoeuver in narrow waters

– Incomplete or fague watch keeping instructions by the captain

– Fit to work. In time on the bridge

– Too many or too few people on the bridge

– Showing or nor showing correct lights/shapes

– Be aware of brightness of working lights for interfering a safe look-out and recognition of the navigation lights

– Give way to anchored vessels

– Inform pilot and being informed by the pilot of planned route

26-10-2017

Example 2b Depart from the Rules

Danger of Navigation

A and B head on PDV’s. Rule 14: Both vessels should alter their course to starboard. Vessel A must depart from this rule

A B

Danger of Collision A,B,C are 3 PDV’s with RoC. Vessel A should maintain C & S for

• 5 Look-out

• 6 Safe speed

• 7 Risk of Collission (RoC)

• 8 Action to avoid RoC

• In good visibility AND in or near an area of restricted visibility.

26-10-2017

28

Rule 5 Look-out

- Who Every vessel. From ULCC to small craft. A look-

out should be fit and well instructed by O of the W

- When In good and bad weather, good and restricted

visibility, day and night, wide ocean and narrow waters, with or without sight barriers,..

- With What Eyes, Ears and All available means appropriate to

circumstances. clean windows, sunglasses, binoculars, radar(s), Ecdis, VHF, AIS, echosounder, corrected charts, ….

- Why To make a full over-look of the situation around

the vessel and/or Risk of Collision

Rule 6 Safe Speed

• Safe Speed is as good Look-out one of the Basements of the Rules

• A Safe Speed also can be too low

- ship not steering - drifting /set - large cross width (drift angle) - overtaking traffic

26-10-2017

29

Rule 6 Safe Speed

• Every vessel

• At all times

• Safe speed = - you can take proper and effective action to avoid collision - you can stop the vessel within appropriate distance

• Factors in determining safe speed - (a) all vessels (always) - (b) + operational radar

Rule 6 Determining Safe Speed

(a) by All Vessels:

• Visibility

• Traffic Density

• Manoeuvrability of the Vessel

• Background Light

• State wind, sea, current, navigational hazards

• Draft – Depth

26-10-2017

30

Rule 6 Determining Safe Speed

(b) Additional with operational Radar:

• Characteristics – Efficiency – Limitations of the radar

– you should know what YOU can do with THIS radar

– how good are YOU and how good is your RADAR

• Constraints by used Range

• Influence Sea state – Weather – Other Interference

• Worse detection Small craft – Ice

• Vessels detected by radar

• Exact Assessment of the Visibility

Rule 7 Risk of Collision

• Every Vessel shall use all available means to determine risk of collision.

• If in doubt, such risk deemed to exist

• Proper use shall be made of Radar, including

– Long range scanning (?)

– Plotting system

• No assumptions on scanty Information, especially scanty radar information. (?)

26-10-2017

31

Rule 7 Risk of Collision (cont.)

Risk of collision :

• deemed to exist if the Compass Bearing of an approaching vessel does not appreciably change

– Why compass bearing?

– Why not appreciably

– With radar only?

• may sometimes exist, even when the appreciable

bearing change is evident.

(?)

Rule 8 Action to Avoid Collision

• Any Action must be

– in accordance with Rules

– positive (doelmatig)

– in ample time

– good seamanship

• Action large enough to be apparent for other vessels. A succession of small alterations must be avoided

• Pass other vessel(s) at safe distance

Check your Action until other vessel is passed and clear

• A good manoeuvre to avoid RoC is slacken your speed or if necessairy stop your vessel completely

It also gives you time to access (beoordelen) the situation

26-10-2017

32

8f Not to Impede !!!

• 8f(i) A vessel which is required by the Rules* not to Impede the (safe) passage of another vessel shall take early action to give sufficient room for a safe passage

– * Rule 9, Rule 10, Rule 18

• 8f(ii)The not-to-impede-rule remains in force if during approaching risk of collision arises

When now taking action, have full regard to an action of the other vessel required by the Rules!!

• 8f(iii)The vessel-not-to-be-impeded must comply with the rules if during approaching one another RoC arises

Rule 16 Action by Give-Way Vessel

Any Give-Way vessel shall so far as possible take:

• Early and Substantial Action to keep Well Clear

• Rule 16 versus Rule 8 Action to avoid collision

Rule 8 Action to Avoid Collision

• Any Action – taken in accordance with Rules – positive - in ample time – good seamanship

• Action large enough to be apparent for other vessels. A succession of small alterations must be avoided

• If there is sufficient sea room, alteration of course alone may be the most effective action

• Passing at safe distance - Check your Action until other vessel is passed and clear

• Slacken speed or take all way off if necessary to avoid collision or to allow more time to access the situation

• Not to Impede rule

26-10-2017

47

Rule 17 Action by Stand-On Vessel

• Where one of two vessels must give way, the other shall keep her course and speed

• The stand-on vessel may take action as soon as it becomes apparent that the give way vessel is not taking action. BUT • A power driven stand-on vessel shall not alter course to port for

a power driven give-way vessel on her own port side

• The stand-on vessel must take action if collision cannot avoided by give-way vessel alone – Such action shall be the best to avoid collision (and has no

limitations as mentioned above)

• This rule does never relieve the give-way vessel of her obligation to give way!!

Attention!!!

• Complying with Rule 17 a(ii) and 17c (action if give way

vessel does take appropriate action) is NOT the same as complying with rule 2b

• Rule 17 means complying with the Rules. Rule 2b means departing from the Rules, only allowed if necessairy in special circumstances to avoid immidiate danger

Rule 18 Responsibilities Between Vessels

• Except where Rule 9, 10 and 13 otherwise require

– Rule 13 Any overtaking vessel must give way

– 9 and 10 not to impede rules!

• A power driven vessel underway gives way to all other categories

• Sailing vessel? Fishing vessel?

• RAM and NUC?

• Any vessel other than a NUC or RAM shall avoid impeding the safe passage of a deep draft vessel.

The latter vessel shall navigate with particular caution.

Rule 19d

• Every vessel which detects another vessel with radar, MUST determine if a dangerous situation develops. If so, every vessel MUST take action to avoid this in ample time.

• IF this action is an alteration of course the next alteration of courses shall (as far as possible) be avoided:

Rule 19 d

All ships in restricted visibility, not in sight of one

another must avoid:

1. Altering Course to Port for a crossing or head on vessel approaching forward of the beam other than a vessel being overtaken

2. Altering Course towards a vessel abeam or abaft the beam.

Difference section II and III

In close quater situation or RoC:

• Section II: one vessel gives way, the other keeps course and speed (stands on)

• Exeption?

• Section III: Every vessel must take action • Why this difference?

Comparing sections II and III

• Actions by vessels, not in sight of one another, taken on the basis of Rule 19, are very close to the actions taken by power driven vessels in sight of oneanother in section II.

• Let us compare rule 13, 14, 15 and 17 with rule 19
