STRAITREP
The mandatory ship reporting system in the Straits of Malacca and Singapore, adopted by IMO Resolution MSC.73(69) and operated jointly by three states.
STRAITREP is the mandatory ship reporting system covering the Straits of Malacca and Singapore, adopted by IMO Resolution MSC.73(69) on 19 May 1998 under SOLAS regulation V/8-1 and in force from 0000 UTC on 1 December 1998. It is an IMO instrument rather than a national one, and it is operated jointly by the vessel traffic services of Malaysia, Indonesia and Singapore.
Coverage runs between longitudes 100 degrees 40 minutes E and 104 degrees 23 minutes E, divided into nine sectors each with an assigned VHF channel: Klang VTS covers sectors 1 to 5, Johor VTS sector 6, and Singapore VTS sectors 7 to 9. Participation is mandatory for vessels of 300 gross tonnage and above, vessels of 50 m or more in length, towing or pushing units meeting either threshold, vessels of any tonnage carrying hazardous cargo, and all passenger vessels fitted with VHF.
The sector table, the report designators and the reporting points are set out in the Strait of Malacca article, which carries the operating detail of the system as a transiting ship meets it.
The full article will cover the sector layout and reporting formats, the relationship to SOLAS regulation V/11, and how the system interacts with the traffic separation scheme and the Deep Water Route .
