MARINE & TERMINALROAD & BULK DISTRIBUTIONFINANCE & COMMERCIAL CONTROL
01 / THE CONTROL GAP
One movement.
Many records.
One financial truth.
The invoice tells only part of the story.
Timing, quantities, rates and contractual exceptions often sit in separate systems. PetroVanguard’s approach brings those records together so the financial position can be reconstructed, challenged and reviewed.
Start with who pays, who holds the contract and who has the right to act. Asset ownership alone does not establish financial exposure.
Follow an illustrative finding02 / AREAS OF REVIEW
Where operations
meet financial exposure.
Focused reviews of the records and agreements that determine what is payable, supportable and actionable.
Demurrage &
Freight &
gantry detention
Compare gate events, dispatch records, billed rates and accessorials with the governing transport agreement. Investigate discrepancies before drawing conclusions.
GATE LOGS · DISPATCHES · INVOICES
Volume &
measurement review
Assess reference conditions, units, calibration and uncertainty. Distinguish explained variation from discrepancies requiring further investigation.
TICKETS · GAUGING · METER RECORDS
Scope is agreed per engagement. Existing volume calculations are functional approximations, not standards-validated implementations. Product-specific methods and specialist review must be established before consequential use.
03 / THE EVIDENCE STANDARD
A finding earns its status.
Potential exposure is never presented as recovered cash. Each step requires its own evidence and authorization.
Flagged
An exception to investigate.
No confirmed loss.
Substantiated
Operational records support a documented discrepancy.
Contract-validated
Executed terms support an actionable position.
Approved
Qualified review and authorized client decision.
Realized
Reliable settlement or accounting evidence verifies the outcome.
Evidence → Contract → Calculation → Approval → Financial outcome
Prevented expense is measured separately. Successive states are never added together as separate benefits.
04 / EVIDENCE IN PRACTICE
See the reasoning.
Not a promise.
A synthetic marine example illustrates how a billed amount becomes a reviewable calculation. Select a step to inspect the assumptions.
SYNTHETIC TEST ONLYNo actual shipment, customer, executed agreement or financial recovery is represented.
ILLUSTRATIVE DEMURRAGE REVIEWPV / TEST 001
RECONSTRUCT THE COUNTED TIME
70 − 6 − 8 = 56 hours
Illustrative elapsed time of 70 hours, less 6 hours of NOR grace and 8 hours of vessel pump failure. Deductions apply only under this scenario’s assumed terms.
ILLUSTRATIVE DISCREPANCY$18,000
A difference to review.
Not realized benefit.
$34,000 synthetic invoice − $16,000 illustrative payable. Contract applicability, evidence and approval are separate gates. No automatic claim or settlement.
05 / START WITH A BOUNDED QUESTION
Clarity before commitment.
A design-partner diagnostic tests evidence sufficiency, materiality and delivery fit before a broader engagement.
DESIGN-PARTNER ENGAGEMENT
A focused feasibility diagnostic.
Begin with a defined sample of historical movements, one commercial question and the relevant agreements. A core scope may cover approximately 50 movements, subject to data quality and complexity.
Fee, timing, review responsibilities and acceptance criteria are agreed in writing. No recovery amount or settlement is guaranteed.
Prepare a scoping brief- 01
Confirm the evidence
Assess completeness, provenance and the missing records that limit a conclusion.
- 02
Reconcile the position
Document calculations, applicable terms, uncertainty and review requirements.
- 03
Decide the next action
Receive a findings brief with priorities, owners and approval gates. Broader work follows only when justified.
06 / CONTROLLED BY DESIGN
Commercial confidence
starts with boundaries.
Confidential records come after authorization
Agree confidentiality, data handling, retention and access before transferring operational records. This public website accepts no document uploads.
Professional judgment remains accountable
Contractual, legal and engineering conclusions require appropriate qualified review. Calculations do not create dispute rights or authorize action.
The client workspace is separate
The Authority Portal is a separate development area. A visual demonstration does not establish secure client access. No client login or private data service is offered on this website.
Current stage and limitations
PetroVanguard is at the controlled design-partner commercialization stage. This website makes no claim of proven customer recoveries, standards certification or production-ready client infrastructure.
