A tie-in point where two or more pipelines are joined to allow fluid or gas transfer between systems. Subcontractors are often mobilised for the hot-tap, welding, and pressure-testing work at these connections. Scope can expand quickly, so confirm tie-in specifications before pricing the job.
Pipeline Interconnect
Related Terms
Reactivation
IndustryThe process of bringing a dormant well, pipeline, or piece of equipment back into active service, often requiring subcontractors to mobilise crews, conduct inspections, and complete compliance checks before full operations can resume. For field service companies, reactivation work can represent a significant surge in contract opportunities, particularly during periods of rising commodity prices.
ERCOT (Electric Reliability Council of Texas)
IndustryThe grid operator managing Texas's independent power network, separate from national grids. Subcontractors working Texas energy projects must understand ERCOT rules govern power availability and outages. Grid instability events like Winter Storm Uri directly impact field site operations and project timelines.
Single-Scope Contractor
IndustryA subcontractor hired to perform one specific, clearly defined scope of work on a project. They operate independently from other trades and are not responsible for coordinating adjacent scopes. This structure limits liability exposure but also restricts opportunities to capture additional work on site.
ILI (In-line Inspection)
IndustryA pipeline integrity assessment using instrumented tools (smart pigs) run through the line to detect corrosion, cracks, or defects. Subcontractors are often mobilised for pig launching, data collection, and follow-up dig verification work. ILI campaigns can drive significant short-notice field service demand.
Retrieval System
IndustryA retrieval system is a method or tool used to recover equipment, tools, or materials from a wellbore or work site. Subcontractors may be responsible for operating or maintaining retrieval systems during fishing jobs or abandonments. Proper handling affects both project timelines and liability.
Header System
IndustryA network of pipes that collects flow from multiple wells or lines into a single outlet point. Subcontractors often tie into or maintain header systems during facility hookups and commissioning work. Knowing the configuration is critical for safe isolation and pressure management on site.
