MN KOSTAS: when the sea does not forgive trifles

Briefly about the incident:

On July 24, 2025, the cargo ship MN KOSTAS flying the flag of Sierra Leone, which departed from the port of Sitia with a cargo of gypsum bound for Lebanon, ran aground on a charted reef in the northeast of Crete. The crew were evacuated and salvage operations began. In August, the hull lost stability and the ship partially sank bow-first in the Kyriamadi area (approximately 3 miles west of Cape Sideros). The authorities classified the hull as a shipwreck (wreck) and ordered the owner to remove it as a hazard to navigation Human factor: what went wrong?

According to the coast guard and industry publications, the master and the officer of the watch were detained for investigative actions — they are accused of “causing a marine casualty” and “failing to take measures to avoid a collision” (in this case — with a reef). A key detail: the reef was marked on navigational charts. This points to a likely navigation error and watchkeeping oversight. Final conclusions will follow the official report of the Greek authorities.

A simple explanation of the “human factor”

In most maritime incidents, the culprit is not a single “fatal step,” but a chain of everyday slips:

Route and “red zones.” If dangerous shoals are charted, the route should have been laid with margin and double-checked before departure. In a risk area — reduce speed and keep heightened attention. (MN KOSTAS grounded exactly on a charted reef.)
Night watch. Darkness, fatigue, and “autopilot” thinking are a dangerous mix. The simple rule: better to wake the master earlier than later.
Double-check. An electronic chart is not a magic wand. The position must be cross-checked with the echo sounder and radar; if something doesn’t “add up” — reduce speed and refine your position.
Alarms. Shallow-depth warnings and “no-go” zones must be enabled and correctly set. This is a free “second pair of eyes.”
Bridge teamwork. A culture of speaking out loud, mutual cross-checking, and the courage to ask questions often separates a near-incident from a safe maneuver.

Five useful lessons for seafarers and cadets:

Plan with margin. Plot a wider route, mark “no-go” zones, and keep a simple pre-departure checklist.
Set depth thresholds and alarms. Don’t ignore audible/visual alerts — first confirm that all is safe.
Reduce speed when in doubt. Doubt = less speed + additional position fixing.
Calling the master early is professionalism. Better a “false” call than a late one.
Case review in class. In training, dissect the MN KOSTAS episode: where the risk was missed and which “barriers” could have stopped the chain of events. (The facts of the incident are corroborated by Greek and international sources.)

Safety and environment

The incident area was under continuous monitoring, fuel was pumped out, tugs and divers worked on site; the authorities announced removal of the hull as dangerous to navigation. No large-scale marine pollution was recorded.

Conclusion

The story of MN KOSTAS reminds us all: the sea rarely forgives “small things.” The reef was on the chart, alarms should have triggered, doubts should have been voiced. When even one link fails, an accident becomes a matter of time. It’s better to learn before incidents — from others’ mistakes rather than your own.
