6  DESIGN CRITERIA

.1  Amend paragraph 6.11 as follows:

"6.11  Position fixing

6.11.1  It should be possible for ships to fix their position anywhere within the limits of and in the immediate approaches to a traffic separation scheme by one or more of the following means, both by day and by night:

.1  visual bearing of readily identifiable objects;

.2  radar bearings and ranges of readily identifiable objects;

.3  D/F bearings;

.4  other radionavigation equipment suitable for use throughout the intended voyage.

6.11.2  The position fixing of ships may be supplemented or substituted by shore-based radar and radio direction finder Systems to assist ships which have difficulty to establish their position accurately with the means prescribed under 6.11.1. Such shore-based systems should be approved by IMO before they are recognized as a position fixing system for supporting the safety of navigation in or near traffic separation schemes."

.2  Insert after paragraph 6.15 new paragraphs 6.16 and 6.17 as follows:

"Mandatory routeing systems

6.16  The extent of a mandatory routeing system should be limited to what is essential in the interest of safety of navigation and the protection of the marine environment.
