Technology & Capacity Building

We offer innovative construction solutions such as complete automated welding (Double sided tandem SAW for Horizontal joints and Semi-auto FCAW for vertical joints) & NDT (Automated UT) for LNG tank construction yielding high quality & productivity, enhancement of high deposition submerged arc welding process for duplex stainless-steel material in pipelines, new line of gas regulators for reduced gas wastage and automatic pipe fabrication shop with cutting edge technologies. 

Expertise in Heavy Lifts 

We have an in-house team to provide erection schemes for lifting all types of heavy and critical equipment, columns, reactors, regenerators, absorbers, converters, and heavy structures as preassembled modules, etc., with precision arrangements using heavy lift cranes, gantry arrangements and as well as tailor made lifting systems. 

Equipment Fleet

A large asset-base of construction equipment includes heavy cranes up to 750 T capacity, pipe layers up to 110 T capacity, pipe bending machines, major concreting equipment, and related machinery. 

Digital Transformation

We are geared up to invoke efficiency in terms of project time and resources through business process automation. In this mission, many critical processes like material status tracking, project planning (including special application for cross-country pipeline) progress monitoring, work face planning, work process improvements in field functions like scaffolding and Quality Management through multiple stage gates and Performance monitoring of Supervision for HSE assurance have been digitalized.

Employment of VR technology for HSE training, a number of alert mechanisms to ensure safety in operations, speed control and wastage reductions by IIOT technology in connected equipment, digital induction & skill inventory of workmen, FR technology and digital health monitoring for all project personnel, drone-based survey capability, AR for inspections are to mention a few of ever improving state-of-the-art technologies. 

HSE Enhancement

We strongly believe that every incident is preventable, and the organization is committed, through its ‘Zero Incident Credo’, to providing a safe and healthy workplace. To achieve this, we have developed effective digital solutions to monitor health condition of all workmen using Digital Health Monitoring System, Virtual Reality based HSE Training modules, and a unique Digital tool called Credibility System to track Unsafe Conditions and Acts along with the quantifying the Execution team’s involvement in ensuring a safe working environment on site.

Our HSE Performance received many awards and accolades from esteemed customers like KOC, Saudi Aramco, Sonatrach, PDO, HPCL, IOCL, Reliance as well as independent agencies like Indian Chamber of Commerce, Confederation of Indian Industry, National Safety Council of India, and international organizations like ASSP and ROSPA for our best HSE practices and their implementation at our projects.

Landmark Construction Projects

Landmark project includes construction of the world’s largest refinery for RIL at Jamnagar, India, including its Phase-III petrochemical complex expansion. We were the single largest contributor in building the world’s largest ethylene cracker (ROGC- Refinery Off Gas Cracker) and other units such as pX-4 (para-Xylene), MEG (Mono Ethylene Glycol), LDPE (Low Density Polyethylene), ECS (Ethylene Cryogenic Storage) and PCG (Pet Coke Gasification) units. The ECS Project set a world record for the fastest completion (29 months).

The track record also includes mega onshore gas terminal at Kakinada for RIL and all major processing units of the Bathinda refinery for HMEL. For Cairn India, we built the world’s longest heated and insulated waxy crude oil pipeline and India’s largest onshore oil processing terminal at Barmer, Rajasthan. Another significant and critical achievement is the erection of the world’s heaviest LC MAX Reactors (three in number weighing 2210 MT, 2115 MT and 2105 MT) at India’s first Residue Upgradation Facility of HPCL Visakh Refinery Modernization Project (VRMP).

Our international track record includes cross-country pipelines for ADNOC Gas Processing, KOC & Saudi Aramco, Gas Compression projects at various locations for PDO (viz. Lekhwair, Saih Rawl, Yibal, Saih Nihaydah and Kauther); Dolphin Energy Qatar; Gas Processing Facility for Saudi ARAMCO and polyethylene trains for SADARA Chemical Company, Gathering Centre for KOC and Haliba Onshore Field Development project for Al Dhafra Petroleum (an ADNOC Subsidiary) and n-Paraffin and Derivative complex for Farabi Petrochemicals at Yanbu. 

Major projects under execution include construction of three central processing facilities for Sonatrach – Algeria, Petrochemical Fluidized Catalytic Cracking Unit (PFCCU) & Propylene Recovery Unit (PRU) for HRRL – Barmer, Dual Feed Cracker Block for HRRL –Barmer, Residue Upgradation facility for HPCL – Vizag, 24” x 224 KM of Mumbai Nagpur Pipeline for GAIL and Jafurah Gas Compression Facilities and Cross-country Pipeline for Saudi Aramco.
