The above-water structure of an offshore platform, including processing equipment, living quarters, and wellheads. Subcontractors working topside must meet strict offshore safety and certification requirements. Scope of work and billing rates often differ significantly from subsea or onshore assignments.
Topside
Related Terms
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.
Grid-Tie
IndustryA system that connects on-site power generation to the utility grid. Subcontractors working on grid-tie installations must coordinate with utility companies and meet strict interconnection standards. Common on solar and wind projects in remote industrial or construction settings.
Cavern Storage
IndustryUnderground storage facilities carved out of salt formations or rock, used to hold large volumes of natural gas, crude oil, or other hydrocarbons. Subcontractors handle construction, maintenance, inspection, and integrity testing at these sites, often needing confined-space and geotechnical certifications. Injection and withdrawal seasons create predictable maintenance windows, helping field service companies plan mobilisation.
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.
Deepwater Export Terminal
IndustryAn offshore facility in deep water where oil or gas is transferred from production infrastructure to tankers or pipelines for transport. For subcontractors, these sites require specialised marine certifications and offshore safety training. Mobilisation costs are high, so confirm day-rate structures and expense recovery terms before committing crews.
Heads of Agreement (hoa)
IndustryA preliminary document outlining the key commercial terms agreed between parties before a formal contract is finalised. For subcontractors, it signals serious intent but is not always legally binding. Avoid mobilising crews or purchasing materials based solely on an HoA.
