Industry Glossary Term

Marine Infrastructure

Offshore and coastal structures such as platforms, jetties, pipelines, and subsea systems where field work is performed. Subcontractors must hold marine-specific certifications and follow offshore safety protocols. Mobilisation costs and logistics are typically higher than onshore projects.

Related Terms

Schedule Compliance

Industry

A measure of how consistently a subcontractor completes work within the agreed timeline. Low compliance can trigger penalties, delay progress payments, or affect contract renewal. Tracking it helps field crews identify where mobilisation or scope changes are causing slippage.

Lower-Tier Subcontractor

Industry

A company or sole operator hired by a subcontractor, rather than directly by the prime contractor or owner. Lower-tier subs often face delayed payment cycles and reduced contract visibility. Understanding your tier position affects lien rights, insurance requirements, and invoice routing.

Compressor Station

Industry

A facility that pressurises natural gas to move it through pipelines. Subcontractors are commonly hired for maintenance, instrumentation, and turnaround work at these sites. They often require site-specific safety orientations and H2S certifications.

Gigafactory

Industry

A large-scale manufacturing facility producing batteries or energy components, often for EV or renewable projects. These sites generate major subcontracting opportunities in electrical, civil, and mechanical trades. Expect large crew mobilisations, tight schedules, and industrial construction workflows.

Npv10 (net Present Value At 10% Discount Rate)

Industry

A method operators use to value oil and gas reserves by discounting future cash flows at 10% annually. Higher NPV10 signals a healthier client who can fund long-term projects and honour contracts. Subcontractors can use it to gauge whether a prospect client's asset base justifies pursuing work with them.

Design-Build

Industry

A project delivery method where one contractor handles both engineering design and construction under a single contract. As a subcontractor, you may be brought in mid-scope with limited drawing sets, requiring flexibility. Scope creep risk is higher since designs are still evolving while field work begins.
