A control system combining electrical signals and hydraulic power to operate valves, actuators, and process equipment. Subcontractors working on commissioning or maintenance must be qualified to work on both electrical and hydraulic components. Specialised certification and intrinsically safe tools are typically required on-site.
Electrohydraulic (eh) Control System
Related Terms
DEF (Diesel Exhaust Fluid)
IndustryA urea-based solution injected into diesel exhaust systems to reduce harmful emissions on Tier 4 equipment. Subcontractors must keep adequate DEF on-site, as running out triggers engine derate or shutdown. Factor DEF supply and storage into your remote site logistics planning.
NGL (Natural Gas Liquids)
IndustryHydrocarbons extracted from natural gas, including propane, butane, and condensate. NGL facilities and pipelines generate steady subcontract work in processing, instrumentation, and maintenance. Understanding NGL handling requirements helps crews meet site-specific safety and equipment standards.
Nearshore Abandonment
IndustryThe decommissioning of wells, pipelines, or infrastructure located in shallow coastal waters. Subcontractors typically handle diving operations, cutting, capping, and seabed remediation work. Regulatory requirements are strict, so current certifications and environmental compliance documentation are essential before mobilising.
SPMT (Self-propelled Modular Transporter)
IndustryA multi-axle hydraulic platform vehicle used to move oversized modules, vessels, or heavy equipment on job sites. Subcontractors working heavy lifts or module installation scopes often coordinate directly with SPMT crews. Understanding load-out and transport sequencing is critical for scheduling your own work around these moves.
FPSO (Floating Production, Storage and Offloading Unit)
IndustryA ship-shaped offshore vessel that processes and stores crude oil or gas directly at sea, then transfers it to tankers — for subcontractors, FPSOs represent remote, long-duration worksites with strict offshore safety certification requirements, specialised crew rotation logistics, and scope that can span topside maintenance, marine systems, and instrumentation work simultaneously.
FEED (Front-end Engineering Design)
IndustryThe detailed engineering phase before a project is sanctioned for full construction. For subcontractors, FEED signals that scopes, specs, and vendor lists are being finalised. Winning work during FEED often positions your company for contracts in the execution phase.
