FFS (Fitness-for-service)

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.

An advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds, pipelines, and structural components for defects. It produces detailed cross-sectional images without cutting or damaging the material. Subcontractors offering PAUT services typically require certified Level II or III technicians and specialised portable equipment.

A company hired by a general contractor or directly by an operator to perform a specific portion of work. Subcontractors often specialize in particular services or trades.

The real-time technique of guiding a drill bit through a target formation using geological data. Subcontractors supporting drilling operations may be called in on short notice as geosteering decisions change well paths. Expect scope adjustments and rapid crew or equipment mobilisation when geosteering is active.

A pipeline or flow line system that connects a new offshore wellhead or satellite field back to an existing production facility or platform, allowing operators to develop remote reserves without building standalone infrastructure. For subcontractors, tiebacks often involve specialised subsea installation, inspection, and maintenance scopes that require certified divers, ROV crews, or subsea engineering support.

A network of pipelines, compressors, and facilities that collect hydrocarbons from wellheads and move them to processing points. Subcontractors frequently support construction, inspection, and maintenance work across these systems. Scopes can span remote multi-well pads, requiring strong logistics and crew coordination.
