Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Offshore Commissioning

The process of testing and activating offshore systems and equipment before handover to the operator. For subcontractors, this phase typically requires specialised certifications and offshore survival training. Mobilisation costs and remote logistics significantly affect bid pricing and crew planning.

Related Terms

Alliance Contract

Industry

A long-term agreement where a subcontractor and operator share risks, costs, and rewards on a project. Both parties collaborate closely rather than working at arm's length. Performance incentives and pain/gain sharing are common features.

Strand Jack

Industry

A hydraulic lifting device that grips steel strand cables to raise or lower extremely heavy loads incrementally. Subcontractors use strand jacks for heavy lifts on modules, bridges, and offshore structures. They are often mobilised by specialised rigging crews under a separate lifting subcontract.

ISNetworld

Industry

A contractor management platform used by operators to verify that subcontractors meet safety, insurance, and compliance requirements before being allowed to work on sites. Maintaining ISNetworld compliance is essential for subcontractors working with major operators.

Bakken Play

Industry

A major tight-oil producing region spanning North Dakota, Montana, and southern Saskatchewan and Manitoba. Subcontractors working here should expect high-volume horizontal drilling and multi-stage fracturing scopes. Seasonal road bans and remote logistics significantly impact crew mobilisation and equipment scheduling.

Back-To-Back Well Program

Industry

A drilling schedule where wells are spaced consecutively with minimal downtime between completions. For subcontractors, it means sustained mobilisation of crews and equipment across multiple well sites. Expect extended contract durations but also compressed turnaround times between locations.

Cavern Storage

Industry

Underground storage facilities carved out of salt formations or rock, used to hold large volumes of natural gas, crude oil, or other hydrocarbons. Subcontractors handle construction, maintenance, inspection, and integrity testing at these sites, often needing confined-space and geotechnical certifications. Injection and withdrawal seasons create predictable maintenance windows, helping field service companies plan mobilisation.
