COLREGs : A Basic Guide to ROR
Convention on the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs)
Adoption:
20 October 1972
ENTRY INTO FORCE : 15 JULY 1977
The 1972 Convention was designed to update and replace the Collision Regulation of 1960 which were adopted at the Same time as the 1960 SOLAS Convention.
One of the most important innovations in the 1972 COLREGs was thee recognition given to traffic separation schemes - Rule 10 gives guidance in determining safe speed, the risk of collision and the conduct of vessels operating in or near traffic separation schemes.
The first such traffic separation scheme was established in the Dover Strait in 1967. It was operated on a voluntary basisi at first but in 1971 the IMP Assembly adopted a resolution stating that the observance of all the traffic separation schemes be made mandatory - and the COLREGs make this obligation clear.
Technical provisions
The COLREGS include 41 rules divided into Six Section :-
Part A - General
Part B - Steering and Sailing
Part C - Lights and Shapes
Part D - Sound and Light signals
Part E - Exemptions
Part F - Verification of compliance with provisions of the Convention.
Further more, there are also 4 Annexes containing technical requirements and concerning lights and shapes and their positioning; sound signalling appliances, additional signals for fishing vessels when operating in close proximity and international distress signals.
PART A - GENERAL ( RULES 1-3 )
PART B - STEERING AND SAILING ( RULES 4-19 )
SECTION 1 - CONDUCT OF VESSELS IN ANY CONDITION OF VISIBILITY ( RULES 4-10)
➡RULE 7: Covering risk of collision, which warns that “ assumptions shall not be made on the basis of scanty information, especially scanty radar information.
➡RULE 8: Covers action to be taken to avoid collision.
➡RULE 10: This collision Regulations deals with the behaviour of vessels in or near traffic separation schemes adopted by the Organisation. By regulation 8 of Chapter V ( Safety of Navigation ) of SOLAS, IMO is recognised as being the only organisation competent to deal with international measures concerning the routing of ships.
The effectiveness of traffic separation schemes can be judged from a study made by the International Association of Institutes of Navigation (IAIN) in 1981. This showed that between 1956 and 1960 there were 60 collisions in the Strait of Dover; twenty years later, following the introduction of traffic separation schemes, this total was cut to only 16.
To enable this to be done as quickly as possible the MSC has been authorised to adopt and amend Traffic Separation Schemes on behalf of the Organisation.
Rule 10 states that ships crossing traffic lanes are required to do so “as nearly as practicable at right angles to general direction of traffic flow”. This reduces confusion to other ships as to the crossing vessel’s intentions and course and at the same time enables that vessel to cross the lane as quickly as possible.
Fishing vessels “shall not impede the passage of any vessel following a traffic lane” but are not banned from fishing shall not impede the passage of any other vessel navigating within a narrow channel or fairway”.
In 1981 the regulations were amended. Two new paragraphs were added to Rule 10 to exempt vessels which are restricted in their ability to manoeuvre “when engaged in an operation for the safety of navigation in a traffic separation scheme” or when engaged in cable laying.
In 1987 the regulations were again amended. It was stressed that Rule 10 applies to traffic separation schemes adopted by the Organisation (IMO) and does not relieve any vessel of her obligation under any other rule.
It was also to clarify that if a vessel is obliged to cross traffic lanes it should do so as nearly as practicable at right angles to the general direction of the traffic flow. In 1989 Regulation 10 was further amended to clarify the vessels which may use the “Inshore traffic Zone”.
SECTION II - CONDUCT OF VESSELS IN SIGHT OF ONE ANOTHER ( RULES 11-18)
➡RULE 11 : Says the section applies to vessels in sight of one another.
➡ RULE 12 : States action to be taken when two Sailing vessels are approaching one another.
➡RULE 13 : Covers Overtaking - the overtaking vessel should keep out of the way of the vessel being overtaken.
➡RULE 14 : Deals with Head-On situations. Crossing Situations are covered by Rule 15 and action to be taken by the Give-way vessel is laid down in Rule 16.
➡RULE 17 : Deals with the action of the stand-on vessel may “ take action to avoid collision by her manoeuvre alone as soon as it becomes apparent to her that the vessel required to keep out of the way is not taking appropriate action.
➡RULE 18 : Deals with responsibilities between vessels and includes requirements for vessels which shall keep out of the way of others.
SECTION III - CONDUCT OF VESSELS IN RESTRICTED VISIBILITY ( RULES 19 )
➡RULE 19 : Stated every vessel should proceed at a safe speed adapted to prevailing circumstances and restricted visibility. A vessel detecting by radar another vessel should determine if there is risk of collision and if so take avoiding action. A vessel hearing fog signal off another vessel should reduce speed to a minimum.
PART C - LIGHTS AND SHAPES(RULES 20-31)
➡RULE 20 : States rules concerning lights apply from Sunset to Sunrise.
➡RULE 21 : Give Definitions.
➡RULE 22 : Covers visibility of lights - Indicating that lights should be visible at minimum ranges (In Nautical Miles) determined according to the type of vessel.
➡RULE 23 : Covers lights to be carried by Power-driven Vessels Underway.
➡RULE 24 : Covers lights for Vessel Towing and Pushing. ➡RULE 25 : Covers light requirement for Sailing Vessels Underway and Vessels Under Oars.
➡RULE 26 : Covers light requirements for Fishing vessels.
➡RULE 27 : Covers light requirements for Vessels Not Under Command or Restricted in their ability to Manoeuvre.
➡RULE 28 : Covers light requirements for Vessels Constrained by their Draught.
➡RULE 29: Covers light requirements for Pilot Vessels.
➡RULE30: Covers light requirements for Vessels Anchored and Aground.
➡RULE 31: Covers light requirements for Seaplanes.
PART D - SOUND AND LIGHT SIGNALS. . ( RULES 32-37 )
➡RULE 32: Gives definitions of Whistle, Short blast and Prolonged Blast.
➡RULE 33: Says Vessels 12 M or more in length should carry a whistle and a bell and vessels 100 M or more in length should carry in addition a Gong.
➡RULE 34: Covers manoeuvring and warning signals, using whistle or lights.
➡RULE 35: Covers Sound Signals to be used in restricted visibility.
➡RULE 36: Covers signals to be used to attract attention.
➡RULE 37: Covers Distress Signals.
PART E - EXEMPTIONS ( RULE 38 )
➡RULE 38: Says ships which comply with the 1960 Collision Regulations and were built or already under construction when the 1972 Collision Regulations entered into force may be exempted from some requirements for light and sound signals for specified periods.
PART F - VERIFICATION OF COMPLIANCE WITH THE PROVISIONS OF THE CONVENTION.
The Rules, adopted in 2013, bring in the requirements for Compulsory audit of Parties to the Convention.
➡RULE 40: Says that Contracting Parties shall use the provisions of the Code for Implementation in the Execution of their Obligations and responsibilities contained in the present Convention.
➡RULE 41: On Verification of Compliance says that every Contracting Party is subject to periodic audits by IMO.
