3.13 If the above exploration activities lead to the finding of
important exploitation prospects, the effect of subsequent exploitation on the safety of
marine traffic should be considered carefully. If the establishment of permanent
installations within a traffic separation scheme is unavoidable, permanent amendments to
the scheme, if deemed necessary, should be submitted to IMO for adoption.
"3.14 Governments establishing routeing systems, no part of
which lie beyond their territorial seas or in straits used for international navigation,
are requested to design them in accordance with IMO guidelines and criteria for such
systems and submit them to IMO for adoption."
3.15 Where, for whatever reason, a Government decides not to
submit a routing system to IMO, it should, in promulgating the system to mariners, ensure
that there are clear indications on charts and in nautical publications as to what rules
apply to the system.
3.16 Governments establishing routeing systems, other than
traffic separation schemes, no parts of which lie beyond their territorial seas, are
recommended to follow the same procedure as that set out in paragraphs 3.14 and 3.15
above.
"3.17 A routeing system, when adopted by IMO, shall not be
amended or suspended before consultation with and agreement by IMO, unless local
conditions or the urgency of the case as described in paragraph 3.19, require that earlier
action be taken. In considering the proposal, IMO shall take account of the objectives,
procedures, responsibilities, methods and criteria for routeing systems as set out in
these General Provisions. A mandatory routeing system, when adopted by IMO, shall not be
temporarily amended or suspended except in urgent cases as described in paragraph
3.19."
"3.18 Mandatory routeing systems should be reviewed, as
necessary, by the Government or Governments concerned taking into account pertinent
comments, reports and observations on the routeing system. Elements under review might
include variations to traffic patterns, offshore exploration and exploitation,
hydrographical changes, effectiveness of aids to navigation and other developments."
"3.19 In an emergency such as might result from the
unexpected blocking or obstruction of a traffic lane or any other part of a routeing
system by a wreck or other hazard, immediate temporary changes in the use of the affected
traffic separation scheme or other routeing system may be made by the responsible and
sponsoring Government or Governments, with the objective of directing traffic flow clear
of the new hazard. In such cases, every possible measure shall be taken by the Government
or Governments concerned to immediately inform shipping of the hazard and of the temporary
changes which have been made.
The responsible and sponsoring Government or Governments should inform
IMO as soon as possible of any such changes and their justification."
