In addition to the pipeline construction, Punj Lloyd’s scope of work includes construction/installation of:
- 24 valve stations
- Seven intermediate pigging stations
- One dispatch terminal
- One receiving terminal
- Leak detection
- A fire and gas system
- A gas management system
- A solar power system.
Punj Lloyd Dabhol to Bangalore Pipeline Project Manager M. P. Ranawat says that pipelines do not often use solar power, and that this system – which provides back-up power to the control buildings – is unique to the Dabhol to Bangalore Pipeline. The design, engineering, installation, and commissioning of the solar power system was done in-house through the company’s renewable arm, Punj Lloyd Delta Renewables.
“The stand-alone solar power system will meet the power demand of instrumentation/telecom equipment and an electrical lighting load of 1,000 watt-peak, while charging through the grid,” says Punj Lloyd Delta Renewables Chief Executive Officer Dr Tariq Alam.
Crossing with trenchless
The pipeline route included 27 river crossings, of which eight were horizontal directionally drilled (HDD). The longest HDD bore is 1,600 m at Ghatprabha River crossing.
