Tank Battery

Natural gas cooled to -162°C to become liquid for easier transport and storage, creating specialized work opportunities for subcontractors in cryogenic equipment maintenance, pipeline construction, and terminal facilities that require specific safety certifications and cold-weather expertise.

A form of metal damage where hydrogen causes stacking cracks to form perpendicular to applied stress in steel pipe and pressure vessels. Common in sour service environments like H2S-containing oil and gas systems. Subcontractors doing inspection or repair work must flag suspected SOHIC immediately, as it signals serious structural failure risk.

A category of ongoing field service work covering routine inspections, preventive maintenance, and corrective repairs on infrastructure or equipment, often awarded to subcontractors through standing agreements or blanket contracts. For field service companies, IMR scopes provide a reliable stream of recurring work but typically require crews to mobilise quickly and hold multiple trade certifications to meet operator requirements.

A method where multiple wells are drilled from a single surface location, or pad. For subcontractors, this means sustained, back-to-back work cycles with minimal rig-up and tear-down time. Efficient mobilisation and crew scheduling are critical to maintaining productivity across the pad.

The reinforced concrete foundation slab supporting a structure's entire load. Subcontractors doing civil or concrete work often mobilise early to complete basemat pours before other trades arrive. Scheduling and cure time directly affect downstream scopes.

A contract between an operator and a service company that establishes the general terms and conditions for all future work. Individual jobs are then executed under work orders or AFEs referencing the MSA.
