Offshore operating zones typically under 500 feet of water depth. For subcontractors, these sites use jack-up rigs and barges rather than deepwater vessels. Crew access, equipment requirements, and mobilisation costs differ significantly from deepwater scopes.
Shallow-Water
Related Terms
All of the Above (energy Policy)
IndustryA government strategy supporting oil, gas, renewables, and nuclear simultaneously rather than picking one energy source. For subcontractors, it means diversified project opportunities across multiple energy sectors. Crews and companies that can work across sectors gain a competitive advantage in bidding.
LNTP (Limited Notice To Proceed)
IndustryA partial greenlight from a client authorising subcontractors to begin limited, specific work before the full contract is executed. It typically covers early mobilisation, procurement, or site prep activities only. Scope and spending are strictly capped, so track your costs carefully to avoid unauthorised overruns.
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.
FSU (Floating Storage Unit)
IndustryA 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.
Default Order
IndustryA purchase or work order automatically issued to a subcontractor when a client's primary vendor cannot fulfil a job. It serves as a backup contract, so subcontractors should confirm scope and rates before accepting. Default orders may come with tighter mobilisation timelines.
AGC (Associated General Contractors of America)
IndustryA U.S. trade association representing general contractors in construction. Subcontractors working with AGC members often encounter standardised contract templates and safety compliance expectations tied to membership. Knowing AGC standards helps subs align bids and prequalification documents with GC requirements.
