Facility Tie-in

Facility that strips raw natural gas of water, impurities and natural gas liquids before pipeline transport. Subcontractors here handle instrumentation, mechanical and electrical work under strict process safety rules. Turnarounds at these plants often mean tight schedules and large multi-crew mobilizations.

A lightweight gas turbine adapted from jet engine technology, used for power generation and compression on oil and gas sites. Subcontractors are often called in for maintenance, hot-section inspections, and component exchanges. These units start up quickly and are common on remote or temporary installations.

A standard shipping container measurement used to calculate freight capacity and logistics costs on large projects. One TEU equals one standard 20-foot container. Subcontractors mobilising equipment or materials to remote sites often quote and invoice freight in TEUs.

Electrical equipment used to control, protect, and isolate power systems on job sites. Subcontractors working near switchgear must follow strict lockout/tagout procedures. Installation and maintenance work often requires certified electricians and site-specific safety permits.

A midstream processing facility installed along an existing pipeline to extract natural gas liquids like propane and butane. Subcontractors are frequently mobilised for construction, maintenance, and turnaround work at these sites. Work scopes often include compression, refrigeration, and fractionation system servicing.

A designated docking space where vessels load or offload equipment, materials, and crew. Subcontractors must coordinate mobilisation schedules around berth availability to avoid costly delays. Port congestion can directly impact your invoicing milestones and crew rotations.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.

How Rig Count Trends Affect Subcontractor Demand and What to Do About It

Rig counts are the earliest signal of where field service work is heading. Learn how to read drilling activity trends, anticipate demand shifts, and position your crew before the phone stops ringing.

What Is an AFE in Oil and Gas and How Does It Affect Subcontractor Payments?

An AFE (Authorization for Expenditure) controls every dollar spent on an oilfield project. Learn how it affects your billing, change orders, and cash flow as a subcontractor.
