We undertake turnkey construction of process plants for refineries, petrochemicals, fertilizers, chemical plants, gas-gathering stations, crude oil & gas terminals and strategic storage facilities including underground caverns and above ground facilities covering civil works, structural, piping, equipment, electrical & instrumentation erection and heavy lift.

Apart from construction for all the onshore projects executed by our Onshore Vertical on lumpsum turnkey basis, our Construction Services vertical has also undertaken construction for several large projects.

Indian Projects

  • RIL J3 the third expansion wave of the world’s largest refining complex. We have played a major role in RIL J3 petrochemical complex in executing the world’s largest Pet Coke Gasification complex (PCG), the largest Ethylene Cracker (ROGC), and a Para-xylene unit (pX-04), whose addition has made RIL the world largest para-xylene producer. In addition there are downstream units such as Mono-ethylene Glycol (MEG), Low Density Poly Ethylene (LDPE) and some shutdown works in the mega refinery.
  • We played a major role in construction works for 9 MMPTA zero-bottom grass field refinery complex at Bhatinda, set up by Hindustan Mittal Energy Limited (HMEL). Apart from execution of Hydrogen Generation Unit  as an EPC Contract, we have carried out composite construction package for all mechanical and E&I works for 8 different units viz., VGO Unit, DHDT Unit, LPG Unit, MEROX Unit, MS Block Unit, FCC Unit, Delayed Coker Unit and Polypropylene Unit.
  • We have supported Cairn Energy India Ltd., for the development of their oil & gas fields in Rajasthan by setting-up India’s largest Onshore Oil Processing Terminal (Spread over an area of two sq. km) and the cross-country pipeline to transport waxy crude from Barmer, Rajasthan to Bhogat, Gujarat, thereby changing the overall dynamics of crude oil production and import scenarios in India. The 650-Km- long, 24” –dia heated and insulated pipeline is the first-of-its kind in India and the longest in the world. Named as Rajasthan Northern Area Development Project, the project is spread over three distinct locations called Mangala Processing Terminal (MPT), Raageshwari Gas Terminal (RGT) and Thumbali (NR1) Water Field which are interconnected through pipelines and has oil producing capacity of 175,000 BOPD at their peak production rates contributing about 20% of India’s oil production.
  • We have played a critical role in building the world’s largest refinery complex (Phase-I and Phase-II) at Jamnagar for Reliance Industries Ltd. In the Phase II, We were involved in erection of FCCU (Fluidised catalytic cracking unit), CFP (Clean fuel package), two units of CDU / VDU (crude / vacuum distillation unit), alkylation, coker, CPP, offsite & utilities. We also executed the refinery’s main control centre / plant operation building, with blast proof construction, and other buildings like the central administrative building, utility building.
  • We have also commissioned state-of-the-art onshore gas processing terminal at Kakinada, the largest of its kind in India (800 MMSCFD).
