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

  1. 01What exact fact, definition or rule does the original source support?
  2. 02Is the publication date and reference period current enough for the decision?
  3. 03Does the evidence apply to the selected country, activity, buyer and company?
  4. 04What remains a Horizon inference or an untested commercial assumption?
