PT Hendon Mandiri Energi provides pipeline construction, installation, and maintenance services for oil, gas, geothermal, and industrial facilities. Our experience spans onshore and offshore pipeline projects across Indonesia, working for major operators and contractors in the energy sector. From piping fabrication to pre-commissioning, we deliver complete solutions that keep production running safely.
Pipelines are the arteries of any energy facility. They carry hydrocarbons, water, chemicals, and steam under high pressure and temperature. A single failure can stop production, harm the environment, and cost millions. That is why pipeline work demands qualified personnel, certified procedures, and strict quality control at every step.
Complete Pipeline Services
Our pipeline services cover the entire lifecycle of a piping system. We fabricate spools and piping assemblies in our workshop or on site, using qualified welders and approved welding procedures. Installation includes pipe alignment, welding, support installation, and hydrotesting of completed systems.
Tie-in works are one of our specialities. Connecting new lines to existing operating systems requires careful planning, precise measurement, and often hot work permits. Our teams execute tie-ins with minimal disruption to ongoing operations, coordinating closely with plant operators.
Hot Tapping and Live Line Works
When connections must be made to pressurized lines without shutdown, we perform hot tapping and stopple operations. These services allow operators to install branches, valves, and instruments while the line remains in service. Our hot tapping crews are experienced across pipe sizes and pressure classes, using certified equipment and following strict procedures.
Hot tapping eliminates the cost and risk of full shutdowns. For operators, that means continuous production, no flaring, and no loss of revenue. For our team, it means rigorous preparation, pressure calculations, and constant monitoring during the operation.
Pre-Commissioning and Testing
Before a pipeline enters service, it must be cleaned, tested, and verified. Our pre-commissioning services include pigging, filling, hydrotesting, dewatering, swabbing, drying, purging, and nitrogen packing. Each step is performed with calibrated equipment and documented with complete test records.
Hydrostatic testing confirms the integrity of the pipeline under pressure. We plan test sections, manage fill and pressurisation rates, monitor pressure and temperature, and record results for client approval. After testing, we dewater and dry the line to prevent corrosion and contamination.
Quality and Safety Standards
Pipeline work is high-risk work. Our welders hold valid certifications, our procedures follow industry codes, and our supervisors enforce permit systems and safe work practices on every job. We maintain inspection and testing plans that cover materials, welds, and final testing, ensuring full traceability.
Safety statistics matter, but so does the culture behind them. Our crews are trained to stop work when conditions are unsafe, to report near misses, and to protect each other on site. This culture, combined with technical competence, is why operators trust us with their critical lines.
Our Track Record
We have completed pipeline projects for refineries, gas processing plants, power stations, and offshore platforms. Our experience includes high-pressure gas lines, crude oil transfer lines, and utility piping systems. We have worked in remote locations, on congested existing plants, and in environmentally sensitive areas.
Each project has strengthened our procedures and our reputation. We bring that accumulated knowledge to every new engagement, adapting proven approaches to the specific conditions of your site.
