Refinery Throughput

A postponement caused by unfinished grid or pipeline tie-in work that prevents a facility from going live. For subcontractors, it often means demobilisation holds, scope gaps, or standby costs with no clear end date. Document all waiting time carefully to support delay claims or change orders.

A scheduled swap of sucker rods in a pumping well, typically requiring a pulling unit crew and rod handling equipment. Subcontractors are often engaged on a per-job or dayrate basis to complete the workover. Accurate job scoping matters, as rod counts and depths directly affect mobilisation time and invoicing.

A BOM (Bill of Materials) is an itemised list of all parts, materials, and components needed to complete a field job. Subcontractors use it to price work accurately and track material costs against their scope. It also supports invoicing and helps avoid disputes over what was supplied on site.

A reserve volume of gas kept in an underground storage facility to maintain pressure and operability. For subcontractors, it affects seasonal work demand and mobilisation schedules near storage sites. Operators draw on or inject gas depending on market conditions, driving fluctuating service needs.

A power generation system that captures waste heat from a gas turbine to drive a secondary steam turbine, boosting efficiency. Subcontractors often support CCGT plants during scheduled outages, commissioning, and maintenance shutdowns. Work typically requires specialised turbine, piping, and instrumentation trades.

A Canadian-designed nuclear reactor that uses heavy water as a moderator and coolant. Subcontractors working on maintenance or upgrades face strict nuclear regulatory compliance and specialised certification requirements. Expect rigorous site access controls, radiation safety training, and detailed documentation standards.
