Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Topside Fabrication

The construction and assembly of the above-water structures on offshore platforms, including decks, modules, and processing equipment, where subcontractors are typically engaged for specialised trades such as structural welding, pipefitting, electrical, and instrumentation work. For field service companies, topside scopes often involve strict offshore safety certifications, remote logistics, and milestone-based billing tied to fabrication progress.

Related Terms

Feasibility Study

Industry

A pre-project assessment that evaluates whether a scope of work is technically and financially viable. For subcontractors, it signals early-stage work that may lead to awarded contracts. Participating in feasibility work can position your company for the larger project bid.

Private Activity Bonds

Industry

Tax-exempt bonds issued by governments to finance private infrastructure projects like pipelines or terminals. Subcontractors may work on bond-funded projects, which often carry strict procurement and reporting requirements. Understanding this can affect how you bid and invoice on qualifying jobs.

Secondary Stress

Industry

Indirect mechanical stress that develops in structures or piping due to thermal expansion, settlement, or equipment movement. Unlike primary stress, it isn't caused by direct applied loads. Subcontractors must account for it during installation and inspection to avoid material fatigue and warranty disputes.

Crown Land Sale

Industry

A government auction where energy companies bid on licences to explore or develop publicly owned land. Winning bids signal upcoming drilling and field activity in that area. Subcontractors watch these sales to anticipate new work and mobilise resources early.

Capital Discipline

Industry

When operators strictly control spending and delay or cancel projects to protect their balance sheets. For subcontractors, this means fewer awarded contracts, reduced scopes, and tighter bid competition. Expect slower mobilisation timelines and more rigorous cost justification from clients.

Trenching Bucket

Industry

A narrow, deep excavator attachment used to dig trenches for pipelines, conduit, or utilities. Subcontractors specify bucket width based on pipe diameter and burial depth requirements. Having the correct size on-site avoids costly equipment swaps and project delays.
