A pipeline tie-in is the physical connection of a new pipeline section to an existing live system. For subcontractors, tie-in work often requires hot-tap certified crews and strict isolation procedures. Scheduling is critical, as tie-ins typically involve planned shutdowns with tight production windows.

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.

An area of abnormally high surface temperature detected during infrared inspection of electrical, mechanical, or process equipment. Hotspots often signal failing components, loose connections, or insulation breakdown requiring urgent repair. Subcontractors must document and report findings promptly to avoid liability and costly unplanned shutdowns.

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.

The ability to move equipment or materials directly via navigable waterways to a project site. For subcontractors, it affects logistics planning, mobilisation costs, and marine transport requirements. Sites with tidewater access often allow heavier loads that road or rail cannot support.

A delivery model where one firm handles both project management and general contracting. For subcontractors, this means a single point of contact manages your scope, schedule, and contract. Expect tighter coordination requirements and change order oversight from the CM/GC.
