how to track draft survey discrepancies?

Track draft survey discrepancy tracking by recording the draft survey variance against agreed shore figures, maintaining a controlled draft survey report trail, and linking outcomes to cargo quantity discrepancy and commercial actions before claims and invoicing escalate.

How Draft Survey Discrepancies Is Applied

• Create a single discrepancy register per voyage and cargo line that stores measured drafts, calculated quantities, and the specific shore figure mismatch it is compared against (initial, revised, and final values).
• Standardize the comparison logic: capture both the vessel-side draft survey report and the shore-side reference, then compute the draft survey variance and store the reason code (measurement method, timing, temperature correction, tank calibration basis, or quantity adjustment).
• Enforce controlled document workflow for the draft survey report: versioning, approvals, and immutable audit trail fields (who changed what, when, and why) so finance and operations can reconcile quickly.
• Link each discrepancy record to downstream commercial events such as statement of facts references, quantity reconciliation outcomes, and any claim or invoice hold decision to prevent revenue leakage.
• Use a reconciliation checklist to ensure every cargo quantity discrepancy has a disposition (accepted, disputed, partially adjusted, or escalated) and a named responsible party for closure.

Operational Impact

1. Revenue protection and financial control: CFOs get earlier visibility on quantity movements and potential claim exposure by seeing draft survey variance before invoicing locks in, with clear disposition status and approval history.
2. Audit readiness and defensible evidence: Audit trails remain complete because each draft survey report version is tied to the discrepancy register, including the shore figure mismatch basis and the exact correction rationale.
3. Faster operational resolution: Fleet and Marine Managers reduce cycle time by using consistent reason codes and standardized reconciliation steps, preventing repeated rework when charterer discussions or quantity disputes arise.

Important to know: Keep discrepancy tracking at the same granularity as the commercial contract, typically by voyage, cargo grade, and tank or line item, and require that every update includes both a reason code and a reference to the underlying measurement or shore reference so the audit trail stays usable during disputes.
