Safety: USS Fitzgerald Collision

A Cole with No Explosives?

USS Fitzgerald

This past weekend, the USS Fitzgerald, a Burke class, Aegis equipped vessel, was struck in a t-bone type accident by a large cargo carrier off Japan during night operations; seven sailors were killed.

Ship collisions are hardly rare but a t-bone is, especially involving a naval vessel on patrol.

Most collisions are eliding incidents where parallel vessels merge due in part to the complex behavior of large ships moving in close proximity affected by wind, currents and fluid dynamics.

Large vessels have tools to both detect and avoid other vessels including radar and automatic information systems (AIS).

AIS shows the position, course and speed for ships within range as well as broadcasting the same information.

There will be several investigations including by the US Coast Guard.

They would know something about a t-bone.

In September of 2014, Coast Guard cutter Key Largo rammed and sank a fishing vessel off Puerto Rico at 6:35 in the morning.

The National Transportation Safety Board determined that the likely cause of the Key Largo incident was that the sole officer on the bridge fell asleep.

As importantly, the report noted that the officer knew he was unfit for duty because of fatigue but failed to act on his conclusion.

Situational Awareness

In the Key Largo case a second bridge officer was absent doing other duties when the ramming occurred. They would have been both a second set of eyes and a hinderance to falling asleep while standing watch.

The Fitzgerald studies will look at staffing, work/rest schedules and bridge activities leading up to the event.

They will also determine how the bridge crew was deployed to maintain an effective lookout.

This incident is an unpleasant reminder of the USS Cole tragedy and the need for warships to be ever vigilant to avoid being rammed or assailed.

While the Cole was not underway when attacked, a smaller vessel took a heavy toll when they came alongside.

It’s also a potent reminder that operating in dynamic environments requires non-stop, tip-top team vigilance.
