RFQ selection reference
Reference fields for quotation comparison. Final values must be confirmed in the signed manufacturer datasheet.
| Selection field | Typical input | Typical input | Typical input | Buyer note |
|---|---|---|---|---|
| Design loads | Hook, setback, wind and simultaneous cases | Mast height and substructure clearance | — | Provide rig equipment and environmental load list |
| Configuration | — | Telescoping, cantilever or conventional modules | Raising, transport and well-center interfaces | State road and site assembly limits |
| Structural verification | Calculations, welding and NDT scope | — | Materials, toughness and inspection | Define certification and design-review requirements |
Product scope
Drilling Rig Masts and Substructures are presented as a quotation-ready equipment family for structural support of drilling hoisting, setback, rig-floor and well-center loads for mobile and conventional rigs. This page helps buyers compare technical offers; it does not promise one model, inventory position, load rating or certification. The final manufacturer must confirm the offered equipment against the rig load case, interface drawings, governing standard editions and signed datasheet.
Selection basis
The main inputs are rated hook and setback loads, simultaneous load cases, wind and seismic data, mast type and clear height, substructure floor height and wellhead clearance, raising method, transport module limits, crown and drawworks interfaces, racking-board loads, stairs and platforms, dropped-object control, welding class, material toughness, NDT, proof or function test, structural calculations and inspection category. Load-path equipment cannot be selected from appearance alone. State whether the request is for new manufacture, replacement, remanufacture or spare parts, and provide maker, model, serial number, nameplate, service history, latest inspection report and dimensioned interfaces for installed equipment. For new projects, attach the rig arrangement, load summary, tubular program, utilities and environmental design data.
Trade and industry context
The cited UN Comtrade record is a broad machinery or hoisting-category export proxy used only to prioritize internationally traded product families. It is not a drilling-only market size or a shipment claim for this equipment. API references identify common technical and inspection boundaries; they do not prove that an unnamed supplier is licensed, certified, authorized or holding stock.
Documents and inspection
Define signed datasheets, general arrangement and interface drawings, structural or load calculations, material certificates, welding procedures, heat-treatment and NDT reports, dimensional inspection, pressure or functional test, proof-load records where applicable, inspection category, certificate of conformity, operating manual, maintenance plan and recommended spares. Verify the actual manufacturer, facility, certificate scope and standard edition before order release.
RFQ checklist
- •Equipment family, new/replacement scope, quantity and delivery date
- •Rated and operating loads, speed, torque, pressure or power cases
- •Rig, tubular, line, structural and utility interfaces
- •Materials, temperature, corrosion and hazardous-area requirements
- •Inspection history, NDT, testing, traceability and certificates
- •Destination, Incoterm, lifting, packing and transport limits
- •Target unit or package price and acceptable technical alternatives
Upload the nameplate, drawings, load cases, inspection records and project specification with the inquiry. Close every interface and certification deviation before comparing price or releasing the order.

Frequently Asked Questions
What information is required to quote Drilling Rig Masts and Substructures?
Provide rated hook and setback loads, simultaneous load cases, wind and seismic data, mast type and clear height, substructure floor height and wellhead clearance, raising method, transport module limits, crown and drawworks interfaces, racking-board loads, stairs and platforms, dropped-object control, welding class, material toughness, NDT, proof or function test, structural calculations and inspection category, quantity, destination, delivery target and required records. Attach nameplates, interface drawings and load cases for replacement equipment.
Are the displayed ratings guaranteed?
No. They are RFQ fields. The final signed datasheet, approved calculations, interface drawings, inspection and test records control the ordered equipment.
Can remanufactured or equivalent equipment be proposed?
Only when the buyer permits it. The offer must identify condition, manufacturer, serial number, inspection history, replaced parts, testing, certification scope and every technical deviation.
