What is Collision Regulations and Ship Master’s Business?

Ship collision is the structural impact between two ships or one ship and a floating or still object such as an iceberg. Ship collisions are of particular importance in marine accidents.


The aim of the Collision Regulations (COLREGs) is to establish rules to avoid collision at sea. The increasing number of ships and condensed traffic on the sea lines of communication makes the COLREGs rather important for safety of the seas.

Frequently Asked Questions

What is the importance of Collision Regulations in maritime industry?

One of the most important innovations in the 1972 COLREG was the 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.

What is collision of a ship?

Ship collision is the structural impact between two ships or one ship and a floating or still object such as an iceberg. Ship collisions are of particular importance in marine accidents.

What are the four 4 annexes of Collision Regulations?

There are also four Annexes containing technical requirements concerning lights and shapes and their positioning; sound signalling appliances; additional signals for fishing vessels when operating in close proximity, and international distress signals.

What is collision avoidance in ship?

Collision Avoidance (CA) is a process in which one ship (manned or unmanned) departs from its planned trajectory to avoid a potential undesired physical contact at a certain time in the future. The ship under control is called Own-Ship (OS).

What is the purpose of international regulations for preventing collisions at sea?

The International Regulations for Preventing Collisions at Sea 1972 (COLREGs) are published by the International Maritime Organization (IMO) and set out, among other things, the “rules of the road” or navigation rules to be followed by ships and other vessels at sea to prevent collisions between two or more vessels.

What is collision Regulation Rule 6?

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.

What are the action to take by the master following a collision?

In every case of collision between two ships, the master is to duly comply as far as possible with following, without endangering his own ship, crew and passengers: He should assist the master, crew and passengers of the other ship in every possible way to save them from any danger caused by the collision.

What is collision liability in marine insurance?

A both-to-blame collision clause is an insurance policy clause that says both vessel owners must share in the responsibility of a collision between ships if the crash was due to negligence. Marine insurance coverage includes such actions as ship sinking or collisions but does not cover wear and tear or war.

What is the priority action of master following a collision accident?

1. Inform the Master and Engine room: This is obvious, but make sure you inform the Master, if he is not on bridge. Inform the engine room and stop the engine. The officer on watch should not hesitate to call the master even if he has the slightest doubt about any given situation.

What is the history of collision regulations?

History of the Collision Regulations For several hundred years there have been rules in existence for the purpose of pre- venting collisions at sea, but there were no rules of statutory force until the last century. In 1840 the London Trinity House drew up a set of regulations which were enacted in Parliament in 1846.

How is risk of collision determined?

Taking compass bearings is one of the most important means of determining risk of collision. Good visibility is needed to use this technique and a series or number of bearings need to be taken. On smaller vessels bearings may be taken using a hand-bearing compass, on larger vessels, a bearing or azimuth ring is used.

What are collision potential points?

This is the point or points toward which one’s own ship should steer at her present speed (assuming that the target does not ma- noeuvre) in order for a collision to occur.

What are the factors to avoid collision?

Key factors to take into account are visibility, traffic density, and vessel maneuverability. The state of visibility: Despite operational radar, a visual lookout is always required by the Collision Regulations.

What corrective action must be taken to avoid collision from both ships?

Action to avoid collision should always be: Positive – make a big alteration of course and/or speed. Made in good time – which means early. Seamanlike – do not make the situation worse for any other ship in the vicinity, assess what they may have to do.

Why do ship collisions happen?

Recent reports on a number of major casualties suggest that simple principles of bridge watch-keeping at sea were not being followed and that human error was found to be the main underlying cause of at least 68 per cent of all collisions.
