collisions. If a VTS system is in place in busy river sections <strong>and</strong> ports, the information provided by AIS<br />

can be used to manage vessel traffic as it gives information about identification <strong>and</strong> movements. The<br />

MRC developed a strategy for the use <strong>of</strong> AIS, which called for implementing AIS coverage <strong>along</strong> the<br />

Mekong River between Phnom Pehn <strong>and</strong> the Viet Nam border <strong>and</strong> future installations <strong>of</strong> AIS equipment<br />

at other strategic locations <strong>along</strong> the Mekong River. Presently about 21 barges, mainly containerships,<br />

sailing between Phnom Pehn <strong>and</strong> Viet Nam are equipped with AIS transponders.<br />

Other important navigation tools are a good working fog-horn (or bad-visibility horn) to warn other<br />

traffic in reduced visibility <strong>and</strong> to give different sound signals <strong>and</strong> an echo-sounder to indicate keel<br />

clearance. Suitable (at least the minimum) navigation equipment onboard, combined with good<br />

waterway infrastructure, allows navigation to be conducted in a safe <strong>and</strong> more efficient manner. On<br />

the Mekong River in Cambodia <strong>and</strong> Viet Nam, tanker barges operating in dense traffic are currently not<br />

equipped with navigation tools that are accepted worldwide as necessary to conduct safe navigation.<br />

Although successful efforts have been made in marking the main channels <strong>of</strong> the Mekong River with<br />

buoys, the waterway infrastructure is far from sufficient to give essential nautical information to the<br />

waterway user. To support inl<strong>and</strong> waterborne transport in difficult situations or when casualties occur,<br />

a VTS system could be <strong>of</strong> great importance. However, this involves the presence <strong>of</strong> VHF equipment<br />

on onboard as well as ashore. Another problem with cross-border <strong>and</strong> international navigation in the<br />

Lower Mekong Basin is the different languages used.<br />

RECOMMENDATIONS<br />

Technical <strong>and</strong> Management<br />

Necessary navigation equipment to be installed on board at the first stage, especially for tanker<br />

barges:<br />

• radar;<br />

• echo-sounder;<br />

• foghorn (bad visibility horn); <strong>and</strong><br />

• VHF.<br />

Necessary navigation equipment to be installed on board at the second stage, especially for tanker<br />

barges:<br />

• GPS; <strong>and</strong><br />

• AIS apparatus.<br />

VTS system set up, or if existing to be extended to involve inl<strong>and</strong> waterway traffic. This includes the<br />

general use <strong>of</strong> VHF equipment.<br />

The owner or operator should provide the necessary equipment to make navigation safer <strong>and</strong> make<br />

sure all crew assigned for watch keeping are familiar with the operation <strong>of</strong> this equipment.
