The arrangement of underwater equipment — wellheads, flowlines, manifolds, and controls — that connects a seabed well to a surface facility. Subcontractors working in ROV operations, umbilical installation, or inspection services must understand this layout to execute scopes safely. Work packages are often structured around specific architecture components.
Subsea Architecture
Related Terms
Long-Cycle Project
IndustryA major capital project with a development timeline spanning several years, such as an LNG (Liquefied Natural Gas) facility or oilsands expansion. For subcontractors, these projects can offer extended contract opportunities but require careful cash-flow planning. Mobilisation costs and payment schedules must be negotiated carefully, as revenue is spread over a long horizon.
Unconsolidated Formation
IndustryLoose, weakly bonded subsurface material — such as sand, gravel, or soft clay — that hasn't hardened into solid rock. These formations create unstable borehole conditions, increasing risk of collapse and equipment loss. Subcontractors drilling or excavating in these zones often face additional scope, specialised equipment requirements, and potential cost disputes.
Infrared Camera Survey
IndustryA thermal imaging inspection using IR (Infrared) cameras to detect heat anomalies in equipment, piping, or electrical systems. Subcontractors use these surveys to identify leaks, insulation failures, or overloaded components without shutting down operations. Clients often require certified IR thermographers, so confirm crew credentials before mobilising.
MOU (Memorandum of Understanding)
IndustryA non-binding agreement outlining the intent to work together before a formal contract is signed. Subcontractors use MOUs to secure preferred vendor status or reserve capacity for upcoming projects. They carry no payment guarantee, so avoid mobilising resources based solely on an MOU.
Saas (software As a Service)
IndustryCloud-based software you access via subscription instead of buying and installing it outright. For subcontractors, this covers tools like invoicing, scheduling, and compliance tracking platforms. You pay a recurring fee and can access the software from any jobsite device.
Suspension Order
IndustryA formal directive from a prime contractor or operator to halt work on a project temporarily. Subcontractors must stop billable activities but may still incur standby costs. Review your contract carefully, as suspension terms affect demobilisation, remobilisation, and delay compensation.
