Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

LPT (Large Power Transformer)

A high-voltage transformer exceeding 100 MVA used in electrical substations and large industrial facilities. Subcontractors are often mobilised for LPT installation, maintenance, or emergency replacement work. These units require specialised rigging, permitting, and certified electrical crews due to their size and criticality.

Related Terms

Midstream Infrastructure

Industry

The pipelines, compressor stations, and processing facilities that move and condition product between the wellhead and end markets. For subcontractors, it represents a major source of maintenance, construction, and inspection work. Contracts here often involve long project timelines and strict regulatory oversight.

Intervention Vessel

Industry

A specialised ship used to perform maintenance, repair, or remediation work on subsea wells and pipelines. Subcontractors are often mobilised to these vessels for ROV operations, well work, or equipment installation. Scheduling and access are tightly controlled by the operator.

Hydrostatic Testing

Industry

A pressure integrity test where pipelines, vessels, or equipment are filled with water and pressurised to detect leaks or weaknesses. Subcontractors are often hired to perform or witness these tests before commissioning. Proper documentation is critical, as clients and regulators require certified test records.

Curtailment

Industry

A reduction or suspension of oil, gas, or construction operations ordered by the operator or regulator. For subcontractors, curtailment often means standby, demobilisation, or reduced scope with little notice. Review your contract carefully for curtailment clauses that affect payment and mobilisation costs.

Oil Battery

Industry

A surface facility that receives, separates, measures, and stores crude oil from multiple wells. Subcontractors frequently work at batteries for maintenance, instrumentation, and tank servicing. It is a common site for ongoing field service scopes.

Condition Monitoring

Industry

The ongoing tracking of equipment health using sensors, vibration analysis, or fluid sampling to detect faults early. Subcontractors may be hired specifically to perform these checks or provide monitored assets. It helps prevent costly breakdowns and supports predictive maintenance schedules on site.
