Confirm the selected heating medium and supply boundary
The oilfield boiler truck is a configured mobile heat source. Establish the required steam, hot-water or separately approved thermal-fluid arrangement and the actual useful duty before choosing equipment. The media are not assumed interchangeable or simultaneously available. A steam-focused review applies only to an identified steam configuration; a general boiler label does not establish a complete hot-oil circulation or wax-removal package.
Confirm the actual boiler, burner, fluid system and control functions in the offer. Water treatment, dual-fuel capability, winter equipment and destination documentation are not assumed standard. Assign distribution, receiver, return-handling and site installation responsibilities explicitly, with relevant evidence and competent project review for the complete arrangement.
Start with the job decision
Mobile Oilfield Boiler Truck projects succeed when the equipment scope is tied to a defined operating duty: supplying an accepted mobile steam or hot-water thermal duty. A useful project document separates normal duty, maximum credible duty, standby or transient conditions and the physical interfaces available at site. This keeps procurement language connected to field reality.
Record steam rate, injection pressure, target steam quality and water-treatment needs as ranges rather than isolated peak figures. The supplier can then explain how the identified steam-generator arrangement, configuration-specific feedwater pump, selected burner and fuel arrangement and identified output-quality measurement scope work together across the intended envelope.
Operating data the RFQ should contain
The RFQ should state the objective for reviewed thermal-support assignments, reviewed well-service heating, accepted wellbore heat supply or selected mobile process heating; expected job duration; fluid or process properties; site utilities; ambient conditions; transport restrictions; hazardous-area basis; and required codes. Where data is uncertain, mark the expected range and identify who owns final confirmation.
| Review item | What to confirm | Evidence or input |
|---|---|---|
| steam rate | Normal, minimum and maximum values | Duty sheet and source calculation |
| injection pressure | Required operating range and limit | Process or well program |
| target steam quality | Quality, composition or site constraint | Laboratory or project data |
| water-treatment needs | Availability and boundary conditions | Site interface schedule |
Define scope boundaries before requesting price
List what is included on the mobile or skid package and what remains with the site. Cover connections, hoses or piping, power and fuel, controls integration, commissioning services, operator training, export packing, recommended spares and documentation. Ask suppliers to list exclusions and deviations explicitly rather than burying them in general notes.
Duty cases, interface data, materials, protection functions, testing and deliverables.
Base scope, options, spares, freight basis, services, delivery milestones and validity.
Use one evaluation sheet for every bidder
Map each proposal against the same requirements. A compliant offer should show selection calculations, component models, package drawings, utility consumption, operating limits and a deviation list. Clarifications should close missing data, not create a new undocumented scope.
Keep a usable project record
Maintain one controlled file containing the approved duty sheet, supplier clarifications, drawings, component data, inspection records, test results, deviations, photographs and signed acceptance documents. Record document revisions and the person responsible for each open item. This prevents the operating team from receiving a package whose final configuration differs from the information used during procurement.
The handover set should also identify installed component models, consumables, calibration intervals, recommended spares, preservation requirements and supplier support contacts. Capture baseline operating readings when the unit is accepted. Those records give maintenance personnel a reference for condition changes and allow later modifications to be reviewed against the original design basis.
Before closing the project, confirm that operators can find the startup, normal-operation, controlled-shutdown and emergency procedures relevant to their unit. Training attendance alone is not sufficient; the responsible team should demonstrate the required checks and know which conditions require escalation rather than continued operation.
Codes, standards and project requirements
Confirm the final specification and acceptance plan against the owner’s project standards, local jurisdiction and ASME Boiler and Pressure Vessel Code resources. The applicable project documents govern whenever they are more specific.
