Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Proved Development Locations

Sites already approved for drilling within a producing field, based on confirmed reserves data. For subcontractors, these locations represent near-term, lower-risk work opportunities. Expect faster mobilisation timelines and more defined scopes compared to exploratory sites.

Related Terms

Long-Span Structural Systems

Industry

Structural frameworks that cover large distances without intermediate supports, such as trusses, arches, or space frames. Subcontractors encounter these in industrial buildings, processing facilities, and modular plant construction. Work in these areas often requires specialised rigging, elevated access planning, and load-path awareness.

Gas Sales Precedent Agreement

Industry

A conditional agreement between a producer and gas buyer that must be satisfied before a project moves to full development. For subcontractors, it signals that major field mobilisation and long-term work commitments depend on this deal closing. Delays or failed negotiations can stall contracts, procurement, and crew deployment.

Voltage Conversion

Industry

The process of changing electrical supply from one voltage level to another using transformers or converters. Field crews must verify site voltage specs before mobilising equipment to avoid damage or downtime. Mismatched voltage is a common cause of costly equipment failures on remote job sites.

Life Extension Drydock

Industry

A scheduled out-of-water inspection and refit that extends a vessel's certified operational life beyond its original design limit. For subcontractors, it signals a concentrated burst of multi-trade work including hull repairs, coating, and systems upgrades. Scopes are often fast-tracked, creating strong short-term demand for specialised labour and materials.

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.

Dynamic Line Rating

Industry

A real-time method of calculating the maximum safe current capacity of a power line based on actual weather and load conditions. Unlike fixed ratings, it allows more power to flow when conditions permit. Field crews may encounter adjusted work protocols near energised lines as ratings shift throughout the day.
