Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Roadway Decking

Temporary modular panels laid over pipelines, cables, or trenches to allow vehicle and equipment traffic across a work site. Subcontractors are often responsible for installation, load-rating compliance, and removal. Costs are typically billable as a mobilisation or site-prep line item.

Related Terms

Mmcf/d (million Cubic Feet Per Day)

Industry

A measurement of natural gas production or flow volume, used to describe the output capacity of a well, pipeline, or facility. Subcontractors use this figure to gauge job scale, equipment sizing, and crew requirements. Higher MMcf/d ratings typically signal larger scopes of work and longer contract durations.

Lease Road

Industry

A temporary or permanent access road built to service an oil and gas lease or well site. Subcontractors are often responsible for maintaining or mobilising equipment over these roads. Road conditions directly affect trucking rates, equipment wear, and scheduling.

Run Schedule

Industry

A timeline that outlines when specific tools, equipment, or crews are deployed downhole or on-site during an operation, dictating when a subcontractor's services are required and for how long. For field service companies, the run schedule directly determines mobilisation timing, crew rotations, and invoiceable hours on location.

Subsea Production System

Industry

A network of underwater equipment — including wellheads, manifolds, flowlines, and control systems — installed on the seabed to extract and transport oil or gas to a surface facility, representing a specialised scope of subsea installation, inspection, and maintenance work that subcontractors must hold specific certifications and equipment to perform. For field service companies, contracts in this space typically involve saturation diving support, remotely operated vehicle (ROV) operations, or subsea engineering services under strict offshore safety and quality regimes.

VLCC (Very Large Crude Carrier)

Industry

A massive oil tanker capable of carrying up to two million barrels of crude. Subcontractors providing marine maintenance, inspection, or coating services may be mobilised to service VLCCs at port or in dry dock. These vessels require specialised certifications and safety compliance for anyone working aboard.

FLNG (Floating Lng Unit)

Industry

An offshore vessel that processes, liquefies, and stores natural gas at sea without a fixed onshore plant. Subcontractors work aboard these units for commissioning, maintenance, and inspection scopes. Access is offshore, so mob costs, safety certifications, and logistics are major bid considerations.
