BWTS Spare-Parts Quotations: Comparing Original and Alternative Offers
Updated
Alternative offers should be compared against an explicit technical specification, not only price and delivery date. The supplier should distinguish original-reference supply, documented equivalents and proposals requiring further assessment.

Key takeaways
- Like-for-like item and contents
- Compatibility evidence
- Installation and verification requirements
- Complete cost and return conditions
Normalise item identity
Compare manufacturer, model, reference, revision, quantity and supplied contents. Identify whether accessories, seals, cables or configuration services are included. Similar wording in two quotations can conceal different supply boundaries and create installation delays.
Review the compatibility basis
Request evidence relevant to the component's function and installation. Measurements, materials, electrical interfaces and approval implications may be relevant. Do not infer equivalence from an unsupported statement that an item suits all BWTS brands or from the visual similarity of catalogue photographs.
Include downstream requirements
Compare installation, calibration, testing, documentation and return conditions alongside the item price. An alternative requiring additional engineering may have a different complete cost. Sea Clean's quotation should identify the offered item and work scope without implying OEM status for independent-brand service.
Illustrative procurement scenario
An alternative component is cheaper but requires a separate interface change and additional verification. The comparison includes those activities and the technical acceptance route rather than comparing item prices alone. The alternative may still be appropriate, but its complete work scope must be visible before the commercial decision is made.
Sea Clean service and quotation requirements
Sea Clean services all EC BWTS manufacturers and variants, including annual instrument calibration, calibration certificates, diagnostics and spare-parts support. Sea Clean is an authorised Headway agent; other manufacturers are serviced independently.
Include the following with the email request: Original specification, alternative offers, installation constraints and evaluation criteria. Multiple vessels in the same area or along an efficient route can be assessed for shared mobilisation. Prices, component availability and attendance arrangements are stated in the quotation.

Frequently asked questions
Is an alternative part automatically unsuitable?
No. Suitability depends on the documented technical and applicable approval basis. The distinction should be evaluated, not assumed in either direction.
