NAV 44/3/2
ANNEX1
4 INFORMATION TO BE PROVIDED TO
PARTICIPATING SHIPS
If necessary, individual
information can be provided to a ship, particularly in
relation to positioning and navigational assistance.
5 RADIOCOMMUNICATIONS REQUIREMENTS
FOR THE SYSTEM, FREQUENCIES ON WHICH REPORTS SHOULD BE
TRANSMITTED AND INFORMATION TO BE REPORTED
The radiocommunications
equipment required for the system is that defined in the
GMDSS for Sea Area A1.
The ship reports can be made
by voice on VHF radio using Ch 13 (GRIS NEZ TRAFFIC) or Ch 69
(DOVER COASTGUARD). Another frequency may also be available
for DOVER COASTGUARD and the Organization will be informed of
the details before the system enters into force.
Ship reports to DOVER
COASTGUARD can alternatively be made by automatic
ship-identification transponder, where available, using a
suitably adapted DSC facility on VHF Ch 70, or equipment
conforming to the standards adopted for the Universal AIS
Transponder.
Confidential information may be
transmitted by other means.
6 RELEVANT RULES AND REGULATIONS
IN FORCE IN THE AREA OF THE SYSTEM
The International Regulations
for Preventing Collisions at Sea 1 972 (as amended) apply
throughout the reporting area. In particular, Rule 10 of
those Regulations applies to the IMO-adopted TSS.
Ships carrying dangerous or
hazardous cargoes and bound to or from any port within the
proposed reporting area must comply with the European HAZMAT
Directive (EC Directive 93/75).
In addition to these
international requirements, the Joint Decree of the Prefet
Maritime de l'Atlantique and the Prefet Maritime de la Manche
et de la Mer du Nord (No. 92/97 -Dest, No. 03/97 -Cherbourg)
control navigation in the approaches to the French coast in
the North Sea, the English Channel and the Atlantic in order
to prevent accidental marine pollution. The Regulations make
provision, in particular, for ships transporting hydrocarbons
(MARPOL ‘73 Annex I), harmful liquid substances (MARPOL
Annex II), noxious substances (MARPOL Annex III), dangerous
goods (IMDG Code), preparing to pass through or remain in
French territorial waters, to send an advance report to the
appropriate CROSS five hours before entering territorial
waters, or six hours before departure. The message sent to
the CROSS must make clear the ship's intended movements in
territorial waters and the status of its ability to manoeuvre
and navigate.
The same Regulations require
ships to monitor VHF Ch 16 or other specific frequencies in
certain areas, and require the reporting of any accident
within 50 miles of the French coast and the taking of any
action required by the maritime authorities to reduce risks.
The United Kingdom has
established a pollution control zone under the Merchant
Shipping (Prevention of Pollution) (Limits) Regulations 1996.
The proposed reporting area is included within those limits.
Ships causing pollution within the area can be prosecuted and
fined more than £250,000.
7 SHORE-BASED FACILITIES TO
SUPPORT OPERATION OF THE SYSTEM Dover Coastguard
The Channel Navigation
Infonnation Service (CNIS) has radar, an Information
Processing and Retrieval System (IPRS), access to the United
Kingdom's HM Coastguard operational radiocommunications, VHF
Direction Finding (DF), radio VHF Digital Selective Calling
(DSC), and Automatic Identification System (AIS) facilities.
CNIS supports the primary responsiblities of preserving
safety of life at sea and co-ordinating responses to
incidents.
7.1 CNIS Facility
The CNIS processing and
display system receives inputs from the radar and VHF DF
equipment, processes the information and presents it on any
or all of six displays. Each display shows processed images
(tracks) from any of the three radar inputs overlaid on a
synthetic map of a selected area, New targets entering radar
range are automatically tagged with a unique track number.
The position, course and speed information of up to 300
tracks is automatically updated and recorded, for each of the
three radars, throughout the vessel's passage through the
CNIS area, giving the CNIS a 900 track capability.
DOVER COASTGUARD maintain a
continuous watch on traffic in the Dover Strait / Pas de
Calais. Operators can add vessel information to the
associated IPRS database (such as name and cargo) and can
display that supporting information on a separate screen.
CNIS is capable of providing an automatic aiarm to identify
any track which strays into an unauthorised area. VHF DF
vectors appear when a VHF radio transmits on the frequency
selected on the VHF DF equipment Recording equipment
automatically stores information from all tracks, which can
either be replayed on the system or specific track movements
can be plotted onto an A0 size sheet of paper. CNIS operators
have access to Lloyd's Register and Hazardous Cargo data on a
separate computer.
