BWTS calibration certificate errors: correct the record without losing traceability
Updated
Sea Clean can help resolve instrument-identity or reporting discrepancies in BWTS calibration records. Send the certificate and the evidence of the discrepancy so the correction addresses the right instrument and preserves the original test history.
Key takeaways

Distinguish a clerical error from missing evidence
A mistyped tag or vessel name may be correctable from the original work record. A missing test point, uncertain serial number or undocumented adjustment requires a different response. Mark the disputed field and provide nameplate photographs, the instrument register and the relevant service report.
Request a controlled revision
Ask the issuing service provider for a clearly identified revised document linked to the original record, with the reason for revision. Do not edit a signed certificate onboard or reuse another instrument's results. If the original test evidence cannot support the requested correction, arrange the necessary verification or retest.
Reconcile the vessel records
Replace the superseded copy in the active register while retaining the revision history. Sea Clean can coordinate corrections to its own service records and scope verification where another record is incomplete. The objective is a usable instrument history, not simply a document with a newer date.
Illustrative procurement scenario
A certificate lists the former transmitter serial number after a replacement. The manager sends the new nameplate and service report so the issuer can determine whether a documented correction or additional testing is needed.

Frequently asked questions
Can a missing calibration result be added later?
Only when supported by the original test record. Where evidence is missing, Sea Clean can quote the verification or retest needed to establish it.
