"8.1 Unless stated otherwise, routeing systems are
recommended for use by all ships and may be made mandatory for all ships, certain
categories of ships or ships carrying certain cargoes."
8.2 Routeing systems are intended for use by day and by night in
all weathers, in ice-free waters or under light ice conditions where no extraordinary
manoeuvres or ice-breaker assistance are required.
"8.3 Bearing in mind the need for adequate under-keel
clearance, a decision to use a routeing system must take into account the charted depth,
the possibility of changes in the sea-bed since the time of the last survey, and the
effects of meteorological and tidal conditions on water depths."
8.4 A ship navigating in or near a traffic separation scheme
adopted by IMO shall in particular comply with rule 10 of the 1972 Collision Regulations
to minimize the development of risk of collision with another ship. The other rules of the
1972 Collision Regulations apply in all respects, and particularly the rules of part B,
sections II and III, if risk of collision with another ship is deemed to exist.
