Terminal-side evidence
Back terminal loss claims with your own calibrated in-terminal measurements — not just the surveyor’s figures. Terminal-vs-tanker deficiency trending shows where losses are actually occurring.
Cargo inspection & loss control
Professional software for cargo, FSO, and field inspection teams.
MaeWest Software is a family of specialised Windows desktop applications for independent cargo expeditors, marine consulting entities, and Floating Storage & Offloading operations in the petroleum and petrochemical industries. Offline-first, signed audit chain, no cloud lock-in.
Why operators choose MaeWest
Evidence-backed cargo operations, defensible years later.
MaeWest is built for the moments when a claim, a survey, or an audit is challenged — and the only thing that matters is whether your records hold up.
Cryptographically verifiable reporting
Every report and bundle is SHA-256 signed and chained. Loading, Outturn, STS, Tank Cleaning, and Suitability reports can be re-verified by any auditor, years after the fact, without access to MaeWest.
Dispute-ready audit trail
Every measurement, correction, and bundle transfer is timestamped and hash-linked to what came before. Any attempt to backdate or rewrite history is exposed by the chain — defensible in demurrage and quality disputes.
Compliance-ready outputs
ISO 8217 grade checks, IMO 2020 and ECA (SECA) sulphur-cap checks, and professional templates for Loading, Outturn, STS, Tank Cleaning and Suitability — aligned with the reporting practices your charterers and regulators already expect.
Initial product release
Two product lines, four focused applications.
The initial release covers Office and Field in MaeWest Cargo Operations, plus Trader and FSO in MaeWest Blending. Each application is built for a specific role and uses verifiable records or signed bundles appropriate to its workflow.
Cargo Operations · Office & Field
MaeWest Cargo Operations
Loss-control and cargo-analytics platform for terminal operators, marine surveyors, and inspection consultants. Standalone Desktop tiers or a Connected Office deployment with signed Field submissions.
- Voyage, Loading, Outturn, and STS operation tracking
- Terminal vs. tanker deficiency trending
- Vetting, product-suitability, and inspector performance reporting
- Multi-unit database (US Bbl/API, m³/Density, m³/SG)

Blending · Trader & FSO · Coming soon
MaeWest Blending
A purpose-built pair of desktop apps for Floating Storage & Offloading operations, currently in pre-release development. The shore Trader will plan blends and issue signed instructions; the vessel FSO will record what actually happened and return a signed ROB snapshot.
- Full ISO 8217 marine-fuel blend calculator (Refutas / ASTM D7152, Chevron flash & pour)
- Restock planning surface: what-if scenarios, change-of-use tank pivots, side-by-side compare, promote-to-issue
- Signed Certificate of Quality PDF with QR verification block
- SHA-256 signed instruction & ROB bundles, verifiable end-to-end
- Reception ceremony: envelope-hash replay guard and chain-continuity checks
- Tamper-evident audit chain with monotonic-clock stamps on both sides
Who it’s for
Built for the people who keep the cargo honest.
For consultants
Deliver value-added analytics without rebuilding bespoke spreadsheets for every client or engagement.
For terminal teams
Monitor cargo loss, product-control performance, and reconciliation patterns with a purpose-built operational tool.
For surveyors
Keep inspection and quantity records tied to trend analysis, VEF review, and management-ready outputs.
For FSO operators & shore Traders
Move blend instructions and ROB snapshots between shore and vessel as signed bundles — no live network, no shared server, no trust in the pipe.
Cargo Operations · QHSE Management System
A quality-management system for operational teams.
MaeWest Cargo Operations includes a QHSE MS designed for day-to-day terminal, survey, and marine operations. Codes of Practice, HSE procedures, operational procedures, structured records, and professional reporting live in the same working environment as the cargo analytics.
Procedures and Codes of Practice
Use a complete quality-management structure covering Codes of Practice, HSE procedures, and operational procedures without starting from a blank folder.
Forms and record keeping
Complete operational forms, save records live to folders on user machines, and keep a retrievable, editable history for follow-up and review.
Professional report templates
Produce consistent reports for Loading, Outturn, STS, Tank Cleaning, and Suitability inspections using the built-in report-template set.
Auditable history
Maintain an audit trail that allows outside auditors to verify records and inspect the chain behind operational changes.
Security by construction
Signed bundles, verifiable everywhere they go.
Every bundle that crosses between apps is content-hashed, re-verifiable, and treated as untrusted until it passes a formal reception ceremony on the receiving side. High-value cargo operations are typically staffed by teams that rotate every few months across different continents and networks — the trust model is designed for that reality.
SHA-256 signed bundlesEvery instruction, execution, and ROB snapshot carries an envelope hash over its full payload. Recipients recompute and re-verify before anything touches their audit chain.
Reception ceremony on importReplays are rejected by envelope hash (not just BundleId), bundle age is classified (Green / Yellow / Red at 30 & 90 days), and out-of-order arrivals from the same sender are flagged for operator review.
Tamper-evident audit chainBoth apps append every operation to a hash-chained audit log that can be independently re-verified. A single altered row breaks the chain and is surfaced in a red banner on every affected report.
Monotonic clock stampsAudit stamps use a persisted monotonic clock, so a wall-clock rollback on either side is detected and recorded instead of silently accepted.
QR-verified Certificate of QualityTrader CofQ PDFs embed a QR verification block encoding the instruction hash and audit-chain head at issue, so a downstream party can confirm the paper matches the source of record.
Offline-first, air-gap friendlyNo live network required. Bundles move over USB, email, or any file transport; the trust model does not depend on the pipe.
No cloud custody of your recordsDatabases and audit chains live on hardware you control. Nothing is shipped to a third-party service as a condition of running the software.
Provenance captured at importTransport medium, source media hint, importing operator, age at import, and any chain-continuity smell are stored alongside the bundle for later reconciliation.
