CPA_ais-244690078|ais-244700631The two ships will approach within ~1 min to a distance of only ~28 m: “LA TERNA” (8 kn) ↔ “OLYMPIC” (8 kn). In reciprocal/intersecting travel, such a close approach is a sign of collision risk. It is an automatic CPA calculation — not a confirmed event, but an early signal. 📋 EVIDENCE (AIS · aisstream): “LA TERNA” MMSI 244700631 @ 51.6168,6.0237 · 8 kn · route 171° | “OLYMPIC” MMSI 244690078 @ 51.6132,6.0245 · 8 kn · route 1° | Measurement: 2026-09-20 19:56:44 UTC
Fast forward to the AIS position, speed and heading of the two ships; If the closest passage distance (CPA) will fall below 0.5 nautical miles, a warning will be generated.
