Guyana is among the first countries in South America to acquire a modern Programme Logic Control (PLC) System. The mechanism was recently installed at the Demerara Harbour Bridge (DHB), which once held the title of the world’s longest floating bridge.
A programme Logic Control system is a digital computer used for automation and electro-mechanical processes, such as control of machinery on factories, assembly lines, amusement rides and light fixtures.
DHB General Manager, Rawlston Adams, stated that this achievement is in keeping with continuous effort to preserve the integrity of the structure. The modern Programme Logic Control system is valued
at $16.1 million.
Adams explained, “A technical crew is now in charge of the bridge during the retraction period, to ensure the smooth operation and subsequently better management of traffic.”
The modernised retractor span control system comprises wireless internet modulators and a control panel which is responsible for sending signals to the four main stations on the bridge causing it to open and close.
The system, which was acquired through the Dutch-owned HM Project Limited, underwent a successful final test run yesterday.
In addition, the DHB operation team underwent a brief informative training session on the functions of the now fully computerised system. Proprietor of the Dutch owned entity, Henny Muskens, explained that unlike the old system, this new PLC is relatively smaller but has the same capacity
The training sessions enlightened the maintenance crew on the updated technology. The team was given firsthand experience on the operations, when the bridge opened on Tuesday.
The new system is controlled by a state of the art, Computer system which will allow for modification of speed and control during tidal strain. Adams says that the system can still function effectively by use of a joy stick as well as digitally.
