A preliminary document outlining the key commercial terms agreed between parties before a formal contract is finalised. For subcontractors, it signals serious intent but is not always legally binding. Avoid mobilising crews or purchasing materials based solely on an HoA.

Carbon Dioxide Treater
IndustryA vessel or system used on oil and gas sites to remove CO2 (Carbon Dioxide) from produced gas or water streams. Subcontractors are often hired to install, service, and inspect these units. Proper handling requires H2S and pressure safety training.
Digital Twin
IndustryA virtual replica of physical equipment or a facility, updated with real-time field data. Subcontractors may use it to plan maintenance, anticipate failures, and align fieldwork with current asset conditions. It reduces surprises on-site and supports more accurate scope planning.
EVA (Extreme Value Analysis)
IndustryA statistical method used to predict the likelihood of rare but severe events, such as equipment failures or extreme weather. Field service contractors use EVA to assess project risk and plan contingency resources. It helps justify standby equipment costs and mobilisation buffers in contract negotiations.
HDPE (High-density Polyethylene)
IndustryA durable, corrosion-resistant plastic used for pipes, containment liners, and fluid transfer systems on job sites. Subcontractors commonly install or tie into HDPE pipelines in water, gas distribution, and environmental remediation scopes. Its lightweight nature reduces handling costs but requires certified fusion welding for pressure-rated connections.
On-Dock Rail
IndustryA rail line built directly inside a port terminal, allowing freight to transfer between ships and railcars without trucking. For subcontractors, this affects equipment and material delivery timelines on import-heavy projects. Factor it into your mobilisation planning when staging gear through coastal terminals.
Liquefaction Train
IndustryA complete processing system that cools natural gas into liquid LNG (Liquefied Natural Gas) for storage and transport. Each train is a major construction and maintenance scope, often requiring large, specialised subcontractor workforces. Shutdowns and turnarounds on these units are high-value contracts with strict schedule demands.
