Horizon synthesis and use
- Vessel behaviour is a useful risk signal but requires legal and ownership analysis. Counterparty, cargo, vessel history, insurer and payment-chain screening should be integrated. Use the dated source as evidence of the reported development; revalidate live operating conditions before travel, shipping, contracting or investment decisions.
Before using the evidence
Four questions that keep the conclusion honest
- 01What exact fact, definition or rule does the original source support?
- 02Is the publication date and reference period current enough for the decision?
- 03Does the evidence apply to the selected country, activity, buyer and company?
- 04What remains a Horizon inference or an untested commercial assumption?
