ROUTEING MEASURES OTHER THAN TRAFFIC SEPARATION SCHEMES
(issued on 23 October 2007)
(Извлечение)
The Maritime Safety Committee, at
its eighty-third session (3 to 12 October 2007), adopted in accordance with the
provisions of resolution A.858(20), the following new routeing measures other
than traffic separation schemes including amendments to existing routeing
measures other than traffic separation schemes, annexed hereto:
.9 amendments to
the Recommendations on navigation through the entrances to the Baltic Sea;
Annex.
AMENDMENTS TO THE RECOMMENDATION ON NAVIGATION THROUGH THE ENTRANCES TO THE
BALTIC SEA
1. When passing through the
entrances to the Baltic Sea, ship should note that the maximum obtainable depth
in most parts of route T is 17 metres. However, in some areas the maximum
obtainable depth is to some extent permanently reduced due to sand migration.
2. The effect of sea level
variations caused by a combination of tide and metrological conditions together
with unknown obstructions on the sea bottom and sand migration could decrease
the depth with as much as 2 metres. Bearing these facts in mind, ships should:
.1 not pass the
area unless they have a draught, with which it is safe to navigate, taking into
account draught increasing effects such as squat effect and the effect of a
course alteration, etc.;
.2 exhibit the
signal prescribed in rule 28 of the International Regulations for Preventing
Collisions at Sea, 1972, as amended, in certain areas in the Storebselt (Great
Belt), Hatter Rev, Vengeancegrund and in the narrow route east of Langeland,
when constrained by their draught.
3.
Ships with a draught of 11 metres or more should, furthermore:
.1 use for the
passage the pilotage services locally established by the coastal States; and
.2 be aware that
anchoring may be necessary owing to the weather and sea conditions in relation
to the size and draught of the ship and the sea level and, in this respect,
take special account of the information available from the pilot and from radio
navigation information services in the area.
4. Ships irrespective of size or
draught, carrying a shipment of irradiated nuclear fuel, plutonium and high
level radioactive wastes on board ships (INF-Code materials) should:
.1 use for the
passage the pilotage services locally established by the coastal States.
5. Shipowners and masters should
consider the full potential of new and improved navigation equipment in the
SOLAS chapter V, including Electronic Chart Display and Information System
(ECDIS) when navigating these narrow waters.
1. Loaded oil tankers with a
draught of 7 metres or more, loaded chemical tankers and gas carriers,
irrespective of size, and ships carrying a shipment of irradiated nuclear fuel,
plutonium and high level radioactive wastes (INF-code materials), when
navigating the Sound between a line connecting Svinbadan Lighthouse and
Hornbaek Harbour and a line connecting Skanor Harbour and Aflandshage (the
southernmost point of Amager Island) should:
.1 use the
pilotage services established by the Governments of Denmark and Sweden;
.2 be aware that
anchoring may be necessary owing to the weather and sea conditions in relation
to the size and draught of the ship and the sea level and, in this respect,
take special account of the information available from the pilot and from radio
navigation information services in the area.
2. Shipowners and masters should
consider the full potential of new and improved navigation equipment in the
SOLAS chapter V, including
