Heavy material (water, sand, or concrete) added to vessels, structures, or equipment to improve stability and balance. In field operations, managing ballast affects load planning, marine logistics, and offshore platform work. Subcontractors on marine or offshore scopes must account for ballast systems in scheduling and safety planning.
Ballast
Related Terms
Baseload Power
IndustryThe minimum level of electrical power a facility requires continuously, regardless of time of day or season. For subcontractors, it determines generator sizing and fuel planning on remote or off-grid job sites. Steady baseload demand also helps forecast equipment runtime and maintenance schedules.
Load Path Planning
IndustryThe process of mapping how heavy equipment or materials will be moved from origin to job site. Subcontractors must identify weight limits, road restrictions, and permit requirements along the route. Poor planning causes costly delays, fines, or equipment damage.
Bentonite
IndustryA natural clay mineral used in drilling fluids to stabilise boreholes and suspend drill cuttings. Subcontractors handling bentonite slurry must follow site-specific mixing and disposal procedures. Improper handling can trigger environmental compliance issues and project delays.
SPR (Strategic Petroleum Reserve)
IndustryA government-held emergency stockpile of crude oil that, when released or replenished, can trigger short-term surges in drilling, transportation, and maintenance contracts as operators respond to shifting supply directives. Field service companies should monitor SPR activity as an indicator of near-term work mobilisation and pricing conditions in their region.
AFE (Authorization for Expenditure)
IndustryA budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.
E&P (Exploration and Production)
IndustryThe upstream segment of the oil and gas industry covering the search for and extraction of hydrocarbons, representing the primary client base that hires field service subcontractors for drilling, completions, well servicing, and site construction work. Understanding whether a client operates in E&P helps subcontractors anticipate project cycles, budget timing, and the boom-and-bust demand patterns that directly affect contract volumes and payment schedules.
