Industry Glossary Term

FLNG (Floating Lng Unit)

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.

Related Terms

MISO (Midcontinent Independent System Operator)

Industry

A regional grid operator managing electricity transmission across central North America. Subcontractors working on power infrastructure or energy facilities in MISO territory must align project schedules with its grid access and outage approval processes. Permitting and energisation timelines are often dictated by MISO interconnection queues.

GPR (Ground-penetrating Radar)

Industry

A non-destructive scanning method that detects buried utilities, pipes, and subsurface anomalies before excavation begins. Subcontractors use GPR to reduce strike risk and meet dig-permit requirements on job sites. Many clients now require GPR clearance as a condition of mobilisation.

Tight Gas

Industry

Natural gas trapped in low-permeability rock formations that require hydraulic fracturing or horizontal drilling to extract. For subcontractors, tight gas projects typically involve intensive well stimulation work and longer mobilisation cycles. Expect higher equipment demands and specialised crew certifications on these sites.

Kelly Bar

Industry

A heavy, telescoping steel rod that transmits rotary torque from a drill rig to the auger or cutting tool. Subcontractors operating foundation or piling rigs must inspect kelly bars regularly for wear and cracking. Damage affects drilling performance and can cause costly downtime on tight project schedules.

Energy Storage

Industry

Systems that capture and hold power (batteries, flywheels, capacitors) for later use on remote or off-grid job sites. Subcontractors use them to reduce generator runtime and fuel costs. They are increasingly specified by clients in ESG-driven scopes.

Grid-Tie

Industry

A system that connects on-site power generation to the utility grid. Subcontractors working on grid-tie installations must coordinate with utility companies and meet strict interconnection standards. Common on solar and wind projects in remote industrial or construction settings.
