Fuel-saving technology from Control Techniques has been installed on rubber-tyre gantry cranes (RTGs) and mobile harbour cranes (MHCs) at Sri Lanka’s Port of Colombo, which is owned by South Asia Gateway Terminals (SAGT).

As part of SAGT’s efforts to improve the health, safety and environmental management of its systems, the company looked at methods for reducing fuel usage within the port and focused in particular on crane diesel usage.

In April 2012, with the help of Control Techniques India, SAGT ran a pilot project to evaluate the fuel-saving potential of the compact RIS.GA system. Following this, an order was placed with Control Techniques for 28 of its RIS.GA systems to be installed on the cranes.

Key benefits of product application

  • The installation of the RIS.GA systems has led to significant savings in diesel fuel, providing a rapid return on investment of less than two years at today’s fuel prices.
  • With fuel-saving technology installed on its cranes, SAGT has been able to reduce the idle engine speed by up to 40 per cent and has achieved a direct fuel saving without any interruption during changeover from operations mode to idle mode.
  • During idle time, the RIS.GA technology supplies the cranes’ auxiliary devices; as a result, SAGT has reduced the total fuel consumption by 22 per cent with minimum modification to the present systems.
  • The Control Techniques systems have effectively boosted crane productivity; as there are fewer fuel stoppages and less wear and stress on the diesel engine, generator and auxiliaries, maintenance downtime and costs have been reduced.
  • As the RIS.GA systems have lowered emissions, the cranes’ environmental impact is also reduced.
