Flowline Construction/Replacement
In the oil and gas industry, flowlines are lines of different diameters that connect a single wellhead to a manifold or process equipment. In a larger well field, multiple flowlines may connect individual wells to a manifold. Flowlines on land may be buried or above ground on the surface of the land. Gathering lines are similar to flowlines but collect the hydrocarbons flowing from multiple flowlines.
Flowlines are located at the well site tied to a specific well. It may be a metallic pipe like Long Length Reinforced Thermo Plastic (LLRTP). Most flowlines run for kilometers in onshore applications.
Flowlines operate as one component of a pumping system. Once a well is drilled, it has to be hooked up to the nearest manifold valve station, or gathering station as the case may. Then only producing fluids can flow to the adjoining facility for oil/water/gas stream separation as appropriate.
The Off-plot delivery scope typically covers the following type of activities • Design and construction of Flowline / Pipeline (new or replacement) • Design and construction of well hook-ups • Civil, Mechanical, Electrical & Instrumentation tie-ins • Design and construction of MSV and manifolds
Construction Deliverables:
1. Well Pad location
2. Well Hookup
3. Flowline (Welding, PE Pulling, Fusion Bonding)
4. Electrical and Instrumentation packages
5. Overhead line completions
6. Live / Shutdown tie-ins Services may additionally include the following: • Carrying out a site survey for a location to assess the existing underground and above-surface facilities • Location access road construction • Borrow pits and restoration of borrow pits after completion of works • Installation of pig launcher stations for pipelines • Road signs for location access • Carrying out of soil test and concrete test • Supply of all materials required for completing the well locations • Site cleaning after completion of construction work .
Flowline Construction Services
In general, the range of services shall include: Construction, Fabrication, Installation, Modification, Repair, Testing, Inspection, Removal and Demolition
Types of Flowlines are typical:
Crude Oil Flowlines, Water Injection Lines, Water Disposal Lines, and Water Supply Lines including pipe works and fittings, related flow line supports, anchors and sleepers either pre-fabricated or fabricated on site.
Quality Assurance / Quality Control
The QA/QC department plays a key role in both ODC and Projects. They are responsible for implementation, operation, and maintenance of the Quality Management System, advising, guiding, and motivating project line management on all Quality and verification activities and related technical matters. They manage staff at work sites, identify and manage risks, conduct audits, provide support and ensure compliance of all functions leading to Flawless Project Delivery.
