A moored vessel used solely to store crude oil or LNG offshore, without production capabilities. Subcontractors are engaged for inspection, maintenance, and marine support work aboard these assets. Mobilisation logistics and offshore safety certifications are typically required before access is granted.
FSU (Floating Storage Unit)
Related Terms
Gas-Directed Drilling
IndustryA drilling approach where well placement decisions are guided by real-time gas readings from formation data. Subcontractors should expect frequent operational pauses for data evaluation and possible scope changes. Mud logging and wellsite geology crews are typically in high demand on these programmes.
Remediation
IndustryThe cleanup and restoration of contaminated soil, water, or sites to meet regulatory standards. Subcontractors are often hired specifically for remediation scopes on legacy sites or post-incident cleanup. Work is heavily documented and subject to environmental compliance sign-off.
Section 232 Tariffs
IndustryU.S. trade tariffs applied to imported steel and aluminium on national security grounds. For subcontractors, these tariffs raise material and equipment costs on cross-border projects. Budget carefully when quoting jobs that involve U.S.-sourced pipe, structural steel, or fabricated components.
Surface Alignment
IndustryThe process of ensuring above-ground equipment, piping, or structural components are precisely positioned and levelled before commissioning. Subcontractors are often responsible for completing alignment checks as a hold point prior to handover. Poor alignment can trigger costly rework and delay final sign-off.
Mwh (megawatt-Hour)
IndustryA unit measuring one megawatt of electrical power consumed or produced over one hour. Subcontractors encounter MWh when billing for generator rentals, temporary power supply, or energy-intensive equipment on remote sites. It also appears in green energy projects where field crews install or service solar, wind, or battery storage systems.
Trenchless Method
IndustryA pipeline or conduit installation technique that avoids open excavation, using methods like HDD (Horizontal Directional Drilling) or pipe bursting. Subcontractors use it to cross roads, waterways, or environmentally sensitive areas with minimal surface disruption. Specialised equipment and certifications are typically required, affecting crew composition and bid pricing.
