Industry Glossary Term

Guidance Engineer

A specialist who oversees directional drilling operations, ensuring wellbores are steered accurately to target zones. Subcontractors often supply these roles to operators on a contract basis. They work closely with MWD (Measurement While Drilling) technicians on site.

Related Terms

Digital Twin

Industry

A virtual replica of physical equipment or a facility, updated with real-time field data. Subcontractors may use it to plan maintenance, anticipate failures, and align fieldwork with current asset conditions. It reduces surprises on-site and supports more accurate scope planning.

Load Growth

Industry

A gradual increase in power demand on a site's electrical system as more equipment and crews are added. Subcontractors must plan for load growth when sizing temporary power installations or generators. Failing to account for it can cause outages, project delays, and costly rework.

Wall Thickness Assessment

Industry

An inspection process that measures remaining material thickness in pipes, vessels, or structural components to detect corrosion or erosion. Subcontractors are often hired to perform these assessments using UT (Ultrasonic Testing) equipment. Results determine whether assets require repair, replacement, or continued monitoring.

Epc (engineering, Procurement, and Construction) Contractor

Industry

A company hired to deliver a project from design through build, acting as the main contractor above subcontractors. As a subcontractor, your client and contract holder is typically the EPC, not the asset owner. They control scope, scheduling, and invoice approval on site.

Marine Infrastructure

Industry

Offshore and coastal structures such as platforms, jetties, pipelines, and subsea systems where field work is performed. Subcontractors must hold marine-specific certifications and follow offshore safety protocols. Mobilisation costs and logistics are typically higher than onshore projects.

Rigging

Industry

The equipment and techniques used to lift, secure, and move heavy loads on a job site. Subcontractors must ensure all rigging gear is certified and operators are ticketed. Improper rigging is a leading cause of serious incidents and contract liability.
