Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Radial Telescopic Conveyor

A mobile conveyor system that extends in length and swings in an arc to stockpile bulk materials across a wide area. Commonly used on pipeline, mining, and civil construction sites for aggregate, gravel, or spoil management. Subcontractors operating this equipment typically require certified operators and may be responsible for setup, teardown, and repositioning.

Related Terms

Electrohydraulic (eh) Control System

Industry

A control system combining electrical signals and hydraulic power to operate valves, actuators, and process equipment. Subcontractors working on commissioning or maintenance must be qualified to work on both electrical and hydraulic components. Specialised certification and intrinsically safe tools are typically required on-site.

BOPD (Barrels of Oil Per Day)

Industry

A measure of a well's or facility's daily oil production output. Operators use BOPD targets to schedule field service work, so higher rates often mean more frequent maintenance contracts and crew rotations. Subcontractors may see BOPD thresholds written into service agreements to trigger additional scope.

Spar Platform

Industry

A floating offshore structure anchored by a deep vertical cylinder, used in deepwater oil and gas production. Subcontractors access it by crew boat or helicopter for maintenance, inspection, and equipment services. Mobilisation costs and offshore scheduling are key considerations when bidding work on spars.

Ip120 (initial Production 120-Day Rate)

Industry

The average daily production output of a new well over its first 120 days. Operators use this benchmark to schedule and extend field service contracts. Strong IP120 results often trigger follow-on work for completions and production crews.

Preventive Maintenance

Industry

Scheduled servicing of equipment before failures occur, reducing costly downtime on job sites. Subcontractors are often contracted specifically to perform PM work on client assets. Documented PM records also support compliance audits and contract renewals.

TOFD (Time-of-flight Diffraction)

Industry

An ultrasonic weld inspection method used to detect and size internal flaws in pipelines and pressure vessels. Subcontractors performing NDT work must hold TOFD-specific certifications to qualify for this scope. It is widely accepted by regulators as an alternative to radiographic testing.
