Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Energy Transition

The global shift from fossil fuels toward renewables, hydrogen, and lower-emission energy sources. For subcontractors, it means new project types, updated certification requirements, and evolving client scopes. Diversifying skills into solar, wind, or carbon capture work helps firms stay competitive.

Related Terms

Gas Processing

Industry

The treatment of raw natural gas to remove impurities and separate saleable products like propane and condensate. Processing plants are major work sites for subcontractors providing maintenance, instrumentation, and turnaround services. Scopes can be large and ongoing, making them reliable sources of repeat field work.

Pjm (pennsylvania-New Jersey-Maryland) Interconnection Queue

Industry

A waiting list managed by PJM for new power generation and transmission projects seeking grid connection approval. Subcontractors use it to track upcoming infrastructure builds and time their bids accordingly. Long queue backlogs signal sustained field work demand in the PJM service territory.

CCGT (Combined-cycle Gas Turbine)

Industry

A power generation system that captures waste heat from a gas turbine to drive a secondary steam turbine, boosting efficiency. Subcontractors often support CCGT plants during scheduled outages, commissioning, and maintenance shutdowns. Work typically requires specialised turbine, piping, and instrumentation trades.

Building Electrification

Industry

The process of replacing fossil fuel-based systems in buildings with electric alternatives, such as heat pumps and induction equipment. For subcontractors, it drives demand for electrical, HVAC, and mechanical retrofits. Crews must often hold updated certifications to work on high-voltage systems and EV (Electric Vehicle) charging infrastructure.

Directional Services

Industry

Specialised drilling support that steers a wellbore along a planned trajectory rather than straight down. Subcontractors provide MWD (Measurement While Drilling) tools, mud motors, and on-site directional drillers. These crews are typically mobilised on a per-well basis under dedicated service contracts.

Tidewater

Industry

Coastal or tidal waterway areas where marine and land-based field operations intersect. Subcontractors working tidewater zones often face dual regulatory requirements and tidal scheduling constraints. Mobilisation windows and equipment access depend heavily on tidal cycles.
