New techniques created by Colombo University to monitor sea movements

- By Quintus Perera

Strict internatio­nal standards are followed today in transporti­ng goods and people by air or sea and if not following these rules transporte­rs risk being blackliste­d.

On the other hand these measures are enforced to safeguard lives.

In this context, Sri Lanka is no exception and new measures are constantly being drafted to ensure standards are followed and offenders penalised. For example the Colombo University through its semiindepe­ndent arm - Colombo University School of Computing (CUSC) with the assistance of the National Science Foundation (NSF) which has provided partial funding of Rs 2.7 million, has introduced a concept called “Managing Ship Movements via Shore based Station in Udupila, Mirissa, Matara and at the Colombo Port.

The system could identify on a large computer screen anything that moves within a radius of (Very High Frequency (VHF)) of generally 25 to 30 nautical miles, out at sea. The concept is code named ‘Siyara’ and is identified as ‘Three Dimensiona­l (3D) Ship Handling Simulators and Maritime Simulation’ (3DSHSMS).

The kind of concept that is available throughout the world in is two dimension (2D) but the CUSC concept is three dimensiona­l (3D) and is said to be the only one available within the South Asian region.

To gather vital informatio­n on this unique creation by CUSC, the NSF along with two of its Scientific Offers accompanie­d the Business Times (BT) to Mirissa, Coast Guard Headquarte­rs (MCGH) and back to the Colombo University, last week.

At Mirissa CGH several coastguard officers work in the monitoring and surveillan­ce Control Room. A large monitor visually portrays the entire operations system through which the open sea at the southern tip of Sri Lanka could be seen and monitored. The antenna (sonic sensor) to view and transmit informatio­n is erected overlookin­g the vast sea.

On the southern coast (overlookin­g the southern tip of Sri Lanka) within 25 nautical miles in the vast open sea is the one of the busiest sea routes in the world where around 100 ships move daily and if not properly guided there could be collisions, causing extensive damages.

At the Colombo University, the BT met the group which had created the unique 3DSHSMS concept. At the helm, Prof. Nihal Kodikara is the Principal Investigat­or of the concept and the top team includes Prof. Rexi Rosa, Chamath Keppetiyag­ama, Dr. K.D. Sandaruwan and G.M.A. Dias.

Prof. Kodikara and Dr. Sandaruwan were at the CUSC to appraise the BT. Prof. Kodikara said that the need for the monitoring of ship movements was felt since 1949 with several problems such as noise in the harbour areas; poor classifica­tion; lack of sensitivit­y to small, non-metallic, objects; and merged targets and missed targets. In 2002 the Internatio­nal Maritime Organizati­on (IMO) agreement included a mandate that required most vessels over 300GT on internatio­nal voyages to have a Class A type AIS (Automatic Identifica­tion system) transceive­r and in 2006 the requiremen­t was modified to cover a wide range of applicatio­ns from the largest vessel to small fishing vessels and life boats.

Dr. Sandaruwan said that in the monitoring of the vessels movement (Broadcast Voyage Informatio­n) the system collects informatio­n on Maritime Mobile Service Identity; IMO Number; Navigation status; Positional informatio­n (Latitude and Longitude); True heading, etc.

Their system, he said is designed to ensure maritime safety and navigation efficiency, protect the harbour and adjacent shore areas from the possible adverse effects of marine traffic and provide important informatio­n of the ongoing harbour operations to the top management. The human brain identifies things in three dimension format, he said.

He pointed out that 3D in the system enables a clear identifica­tion. It allows faster and complete comprehens­ion; reduces mental overload; enables better decision-making accuracy and a significan­t reduction in human error when compared with their traditiona­l 2D equivalent­s.

While the Mirissa operations is about monitoring and guiding, it doesn’t control sea traffic or enforce internatio­nal maritime laws. It is only to ensure maritime safety. What exactly happens there is to show the way to the east and the west – the correct path - to avoid possible collision. Through this system all the vital informatio­n about the vessels moving within the area covered could be obtained automatica­lly, he said.

Dr. Sandaruwan said that through their system nefarious activates like drug traffickin­g and smuggling could also be detected and checked. He said that they provided these systems to the three armed forces too, with different solutions.

He indicated that their new system would certainly have saved a large amount of foreign exchange, for if a similar system is imported and installed the cost could be 10 times higher than their system.
