We offer engineered solutions for pre-commissioning, commissioning, and maintenance shutdowns with specialized services for the oil and gas, power generation, metals and mining, and other process industries. Our integrated package of services includes nitrogen services: purging, helium leak testing, bolt tensioning and torquing, system cooldowns; cleaning services: lube-oil flushing, chemical cleaning, retrojetting, high-velocity flushing; and drying using either air, nitrogen, or vacuum.
BHGE can package these services together to manage the entire pre-commissioning process. This optimizes the utilization of people and equipment, reducing overall cost, decreasing time to system start-up. For plant turnaround, our services minimize outage time while improving plant efficiency. Baker Hughes nitrogen services reduce project time, risk, and cost with efficient nitrogen usage onshore or offshore during new construction or turnarounds.
We support projects in oil and gas production, LNG, refining, petrochemical, power generation. We ensure you have a clean, dry, leak-free, and inert unit ready to safely receive product the first time, according to industry standards.
If temperature is an issue, we can precool or preheat your piping and vessels to the required level. As part of your plant pre-commissioning or turnaround, our leak testing, cleaning, and drying expertise means a faster start-up with greater operating efficiency.
With greater system integrity, meet your HSE objectives and environmental regulations. Our packaged services reduce plant downtime, minimize cost, and HSE risk with a one-stop solution driving greater efficiency.
Our turnaround services provide a one stop solution to reduce cost, plant downtime, and HSE risk. Engineered industrial nitrogen services and chemical decontamination expertise help deliver shorter shutdowns and faster clearing. Our clean-burn variable tip flare technology ensures complete combustion of your waste materials. Clean-burn prevents the release of unconverted hydrocarbon materials, undesirable by-products and solid carbon deposits, ensuring emissions concentrations to reduced significantly below local legislative limits.
Our temporary fuel gas and LNG supply service keeps gas flowing to your customers during outages, ensuring you meet your contractual obligations. Whether a supply shortage in a remote location, planned maintenance work, or an unexpected shutdown, we offer tailored support.
Vaporized LNG is delivered at precisely controlled pressure, temperature, and flow rate for an uninterrupted supply.Pipeline Dewatering / Pigging After Hydrostatic Test ( pre-commissioning)
We can blend other materials to ensure calorific value and molecular weights match your specifications. We can also fuel your turbines, gas compressors, and power generation systems while in the construction yard, allowing you to troubleshoot and commission the units before shipping offshore.Overall and discipline supervision is aimed to ensure that mechanical completion is documented and pre-commissioning and commissioning is completed in the correct sequence, following the approved procedures and duly and timely documented within the completion database:.

Facility Maintenance Services
Pre-shipment inspection. Find out more about cookies. Excellence Behind Excellence. Corporate info Privacy Cookies. VAT number Throughout the life of any oil or gas production or refining facility, maintenance is required annually where a facility halts production to enable the inspection, maintenance and repair, or replacement, of components. Maintenance plans are generally established for each item of equipment and these are followed to ensure optimal performance from the production facility.
In addition to the long term planned maintenance, there are also short term planned and unplanned maintenance requirements. Our procedures and technology is tuned to optimize safety, time and flexibility, ensuring system restart is achieved on, or in a number of cases, ahead of schedule.
The integration of all these related services into a single package allows the various scopes to be easily planned, completed, reported and certified with minimal, or no third party handovers or interfaces, minimizing non-productive time and enhancing safety.
This provides additional benefits from simplification of the permit, to work system through, to an increase in completion quality due to total system ownership, and enhanced safety through real time system awareness. A small, single crew of personnel who can perform all the required shutdown services, provides substantial reductions in manpower requirements and logistical costs which, in turn, help reduce overall shutdown costs.
Key advantages of an integrated suite of shutdown services are the seamless interfaces between each phase of the operation. Sign In Register. Regional Sites. Contact Us.

Thank you very much for updating valuable knowledge but please provide one PDF file save option to download the soft copy. Such a wonderful article for loop check starters. Good job author…Keep up the Excellent Job…. Amazing information. Practical dos and donts… Things to be checked carefully during pre-commissioning…. Wow, a lot of mistakes are in here. How can you state that mbar equals any flow without checking the actual flow element. Level checks should be done with the correct liquid. Diesel for example.

Ash Allam. Joined: 6 Nov Posts : 3.Pipeline pre-commissioning is the process of proving the ability of a pipeline and piping systems to contain product without leaking.
This product may be liquid, gaseous or multiphase hydrocarbonswatersteamCO 2N 2petrolaviation fuel etc. Pre-commissioning is the series of processes carried out on the pipeline before the final product is introduced. The process during which the pipeline is made "live" i. Despite being seen as an offshoot, or minor part of the business for the larger oil service companies, the pipeline pre-commissioning industry possesses quite a large portfolio of services including, but not limited to the following services:.
Pipeline Cleaning — this is carried out by pushing pigs or gel pigs through the pipeline to remove any debris buildup or corrosion. Pipeline Gauging — this is carried out to prove the dimensional quality of the internal diameter of the pipeline.
Pipeline Filling Flooding — which can be carried out by propelling pigs through the pipeline with water or free flooding with water normally for smaller or unpiggable pipelines.
Hydrotesting — this is a process by which the pipeline in question is pressure tested to a predefined pressure above the operating design pressure of the pipeline. Dewatering — this involves pushing pigs through the pipeline propelled by a gas to remove the water prior to start-up.
Other services include vacuum drying, degassing, pneumatic testing, barrier testing, leak testing, decommissioning to mention but a few. On the pipeline process pre-commissioning side, there are various services such as chemical cleaning, helium leak detection, bolting, hot oil flushing, pipe freezing, foam inerting etc Other services include valve testing, umbilical testing, hot tapping, leak metering, riser annulus testing.

Electricity: to provide power for motor, HVAC system, instrumentation control, etc. Compressed air: it is used for pneumatic test Nitrogen: inerting gas line or hydrocarbon storage Demin water: for boiler cleaning or for steam blowing, etc.
Chemicals: used for commissioning activity for several system, such as water treatment, waste water treatment, boiler, cooling water injection, etc. Lube oil: used for lubricating the moving parts of mechanical items. General Precommissioning Activities It shall be noticed that for every project might have different system and different precommissioning activity. In general, precommissioning activities will be conduct for each discipline: 1.
