Reporting System (CALDOVREP)

DESCRIPTION: CALDOVREP is a Mandatory Reporting System under SOLAS Regulation V/8-1.France and the United Kingdom believe that safe navigation in the Dover Strait would be enhanced by the implementation of CALDOVREP. Shore based facilities at GRIS NEZ TRAFFIC and DOVER COASTGUARD are able to monitor shipping movements and provide improved advice and information about navigational hazards and weather conditions. The following categories of vessels are required to participate in the Reporting System:

(1) All vessels of over 300 GT

(2) All vessels of under 300 GT in circumstances where they:

(a) are not under command or at anchor in the TSS or its ITZ’s

(b) are restricted in their ability to manoeuvre

(c) have defective navigational aids

AREA: The Reporting System covers a 65 n mile stretch of the Dover Strait/Pas-de-Calais and is bound by a line to the east drawn from North Foreland to the border between France and Belgium, and by a line to the west drawn from the Royal Sovereign Tower, through the Bassurelle Lt buoy (50º 32'·80 N., 00º 57'·80 E ) to the coast of France.

CALL: NE bound vessels : Gris Nez Traffic

SW bound vessels: Dover Coastguard

FREQUENCY: Gris Nez Traffic: Ch 13

Dover Coastguard: Ch 11

HOURS: H24

PRECEDURE:

(1) North-east bound traffic should report to GRIS NEZ TRAFFIC 2 n miles prior to crossing the southerly reporting line.

(2) South-west bound traffic should report to DOVER COASTGUARD when within VHF range of North Foreland and not later than when crossing the northerly reporting line.

(3) Reports to the nearest of the two shore stations should be made on departure from a port within the ITZ’s of the TSS.

(4) Special reporting arrangements can be made on ship-by-ship basis, subject to approval of both Gris Nez Traffic and Dover Coastguard.

(5) Reports should be made using VHF voice transmissions. However, when reporting to Dover Coastguard, vessels may fulfill the reporting requirements of a CALDOVREP through the use of automatic ship identification transponders.

(6) The report from a vessel to the Reporting System should contain only information which is essential to achieve the objectives of the System:

Designator	Information Required
A	Vessel’s name, call sign, IMO identification or MMSI number for transponder reports
C or D	Position
E and F	Course and speed
O	Draught
L	Route information
P	Hazardous cargo, class and quantity, if applicable
Q or R	Breakdown, damage and/ or deficiencies affecting the structure, cargo or equipment of the ship or any other circumstances affecting normal navigation in accordance with the provisions of the SOLAS and MARPOL Conventions

INFORMATION: Both Gris Nez and Dover monitor shipping in the TSS in the Dover Strait/Pas-de-Calais using radar and each provides regular information about weather and navigational hazards as part of the joint Channel Navigation Information Service (CNIS). Information is broadcast at the following times and on the following frequencies:

Station	VHF Channel	Times	Additional broadcasts in times of poor visibility
Gris Nez Traffic		H+10	H+25
Dover Coastguard		H+40	H+55

Information broadcasts from both stations will end with a reminder regarding the time of the next broadcast and the VHF frequency on which it will be made.
