44,000 MT LPG Transaction: Vessel & Voyage Evidence Reconstruction

The documents described a coherent Houston-to-Tianjin cargo movement. We tested that story against the physical vessel universe, persistent IMO identity and voyage timing before treating it as established.

Evidence Reconstruction · ZR-C001 · 44,000 MT LPG Case

We tested the cargo story against the entire Houston vessel window — not against one document.

Submitted commercial documents remain redacted. The vessel-screening data below uses the actual public vessel names, IMO numbers, capacity and timing used in the verification, so the physical-voyage logic can be evaluated directly.

SUPPORTED CLAIM
POP · Bill of Lading
Houston → Tianjin · 44,000 MT · claimed on-board date

The submitted B/L described liquefied propane loaded at Port of Houston for Tianjin and stated a specific on-board date.

CLAIM
POP · Voyage Report
Claimed flag: Turkey

The voyage report stated “Flag State: Turkey”, with Houston departure around 5 June and revised Tianjin ETA around 3 July.

INDEPENDENT EVIDENCEIDENTITY ANCHOR
Independent Vessel Identity
IMO 9320752 became the anchor

Using the IMO rather than the vessel name allowed us to track the same physical ship across name and flag changes and compare it with the transaction documents.

PHYSICAL TIMELINEWhat the vessel window showed
29 MAYBW ELM enters the relevant Houston windowIMO 9320752 · VLGC-size capacity.
3 JUN NIGHT / 4 JUN UTCBW ELM departs HoustonPhysical movement precedes the claimed departure point.
~5 JUNSubmitted voyage report claims Houston departureDocument-side timeline.
~3 JULSubmitted material gives revised Tianjin ETACommercial narrative continues to Tianjin.
IMO CROSS-CHECK9320752 fixes the physical identityBW ELM · India flag around the relevant period; later SHENG HAI LONG · Marshall Islands.

Key contradiction: the flag claim did not survive the IMO cross-check.

The submitted voyage material identified the vessel as Turkish-flagged. Independent vessel records tied to IMO 9320752 instead showed the same ship as BW ELM under the India flag around the relevant voyage period, later changing name to SHENG HAI LONG and flag to Marshall Islands.

Why this matters: vessel names and flags can change; the IMO number is the persistent identifier. Once the IMO was fixed, the transaction document's Turkey flag claim no longer matched the independent vessel identity history.

Selected rows from the Houston vessel screen

We did not search for a vessel that “looked right.” We built a broader candidate set and eliminated vessels by capacity, timing and destination.

DECISION IMPACTThe submitted cargo story could not be treated as established until the vessel identity, voyage evidence and current commercial authority were reconciled.
Step 1 · Scope the physical universe
22 candidate LPG / VLGC movements

We screened the relevant Houston window rather than assuming the vessel name provided in the POP was correct.

Step 2 · Eliminate by hard constraints
Capacity · Timing · Destination

Smaller LPG carriers, late arrivals, early departures and incompatible destinations were excluded before deeper identity work.

Step 3 · Fix the identity
IMO → history → flag → port calls

The closest physical match was then tested through persistent IMO identity and independent vessel records, exposing the flag inconsistency.

Method note: public AIS and vessel databases can be delayed or retain different snapshots. We therefore do not treat any single database as conclusive; the value comes from reconciling multiple independent sources against the commercial documents and timeline.
