Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Alliance Contract

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.

Related Terms

Bore

Industry

A drilled or excavated hole through soil, rock, or existing structure. Subcontractors are often scoped to complete a specified number of bores per shift. Bore diameter and depth directly affect equipment selection and crew sizing.

Punching-Shear Failure

Industry

A structural failure where a concentrated load punches through a slab or foundation, creating a cone-shaped break. Subcontractors must watch for this risk when positioning heavy equipment on concrete pads or temporary platforms. Undetected, it can cause sudden equipment collapse and serious site liability.

Tidewater

Industry

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.

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.

Closed-Loop Cooling

Industry

A system that recirculates coolant through equipment without discharging it to the environment. Subcontractors must maintain leak-free connections and monitor fluid levels during installation and servicing. Improper handling can trigger environmental compliance violations on site.

Npr-A (national Petroleum Reserve in Alaska)

Industry

A federally managed exploration zone on Alaska's North Slope, open to oil and gas development. Subcontractors working here face strict federal permitting, remote logistics, and seasonal access limitations. Mobilisation costs and compliance requirements are significantly higher than standard onshore projects.
