Fugro System Monitors Malaysian Coast

The tragic consequences of the tsunami that struck in the Indian Ocean on 26 December 2004 have acted as a major eye opener to countries vulnerable to similar disaster. As a result, urgent efforts are being made to establish early warning systems to reduce or minimise the impact of future tsunamis. Accordingly, Malaysia has taken the initiative to implement a tsunami detection system comprising three buoys and a number of automatic tidal stations.

Malaysia has installed a tsunami monitoring system some 200km from the coastline.
Malaysia has installed a tsunami monitoring system some 200km from the coastline.

From a distance of about 200 km from the coastline a seabed mounted pressure sensor will continuously communicate water pressure data to a surface anchored buoy through an acoustic transmission link. As a tsunami is detected an alert will be activated and transmitted via satellite to the operational warning centre.

This enables a warning to be communicated to the population well before the tsunami hits the coast. A number of automatic tidal stations will also be installed along the Malaysian coast to complement the newly installed buoy detection system.

Astronautic Technology Sdn Bhd, the appointed solution provider to the Malaysian Government, has been working closely with Fugro Oceanor, part of Fugro Global Environmental and Ocean Services (GEOS), in establishing the tsunami detection system. Fugro Oceanor has engineered, manufactured and implemented marine monitoring and surveillance systems for many years. Oceanor Seawatch buoy systems installed in the waters off countries such as Spain, Greece, Thailand, India, Vietnam, Indonesia, South Africa and Peru have formed parts of the regional networks of the Global Ocean Observing System (GOOS). This involvement was strengthened in 2004 when, with the assistance of Fugro Oceanor, the operators and owners of these Seawatch systems formed a forum called the Seawatch Partnership. For tsunami warning purposes, the current Seawatch system is easily upgraded, as will be the case off Malaysia.
