Navigational Error Blamed for Coral Adventure Reef Grounding That Left 124 Aboard Stranded for Three Days
About 124 passengers and crew were stranded on the grounded ship for three days before being disembarked and brought ashore.
A very narrow waterway, and a margin for error that is quite small.
Mark
Start with the basics. What does the ATSB say actually caused this?
Mimi
A chain of small things. The chief mate changed the route and speed to smooth a turn, the navigation system froze for a safety check, and the ship missed its turn. The correction made it worse.
Mark
Worse how?
Mimi
Switching to manual steering and adding engine power left the ship 2.5 knots faster than planned and 200m west of its route. Then it couldn't turn to starboard in time.
Luke
Worth saying this is a preliminary report. The sequence is the ATSB's current account, not a final finding. The headline word "blamed" is doing more than the report may yet carry.
Mark
Fair. Why does the darkness matter so much?
Mimi
Mitchell said there were no navigational aids or lights ashore, and the chief mate couldn't visually identify the terrain. In a narrow waterway, that leaves very little margin.
Luke
And that's the chief mate's reported experience, relayed by Mitchell. We don't have the bridge's full record in front of us.
Mark
What do we know about the three days aboard?
Luke
Very little. We know passengers stayed on the ship, then were disembarked and brought ashore. Nothing about conditions, injuries or the rescue itself, so I wouldn't fill that in.
Mimi
The emergency response is on the ATSB's list, so that part of the story is still open.
Mark
And the wider question?
Mimi
Mitchell says they'll review passage planning and navigation procedures across the operator's whole fleet. That suggests they're asking whether this was an individual lapse or a systemic one.
Luke
Right, but "review" isn't a finding. Whether there's a fleet-wide problem is unknown.
Der Puls
- A ship meant to make a careful turn in a narrow channel ended up 160 metres off its route and fast on a reef.
- In the blackness before dawn, with no lights ashore and no clear view of the land, the chief mate was left reading the sea almost blind.
- A frozen navigation system during a safety check, combined with a rushed switch to manual steering and extra engine power, pushed the ship too far and too fast.
- For three days 124 people stayed aboard a grounded hull, and only later were they carried ashore to begin the journey home to Cairns.
- The ATSB has opened a wider inquiry into passage planning and emergency response across the operator's entire fleet, with the final word still to come.
Before dawn on December 27, in the narrow waters off Papua New Guinea's northeast coast, a small expedition ship carrying 124 people drifted from the course it had been set, and the sea took its measure of human plans. The preliminary account now placed before the public points to a chain of small decisions on the bridge: a change of steering and speed, a navigation system that paused at the wrong moment, and a hurried return to manual control in darkness with no lights ashore to guide the way. For three days those aboard waited on the reef before being brought to land, and the investigation that continues will have to decide whether this was one tired morning's failure or a question about how the company plans its passages at all.
A little after 5am on December 27, the expedition cruise ship Coral Adventure was feeling its way toward Dregerhafen, about 100 kilometres east of Lae on Papua New Guinea's northeast coast. Aboard were 80 passengers and 44 crew, partway through a 12-night voyage. By 5:25am the ship had struck a reef, and the people on board would remain there for three days.
The Australian Transport Safety Bureau's preliminary report points to an error on the bridge. The chief mate had altered the ship's steering and speed to make a smoother turn. Then the navigation system froze during a safety check, and the ship missed the turn it was meant to make. Hurrying to correct it, the chief mate switched to manual steering and raised engine power, and the ship surged ahead, travelling 2.5 knots faster than planned and well west of its course.
It was dark, with no navigational aids or lights ashore, and the chief mate reported being unable to make out the surrounding land. ATSB chief commissioner Angus Mitchell stressed how little margin there is in a waterway that narrow. The ship ran onto the reef 160 metres east of its planned route, its hull structurally damaged, and it could not free itself.
For three days the 124 people aboard waited. Eventually everyone was disembarked and taken ashore to arrange their return to Cairns. The investigation continues, and the ATSB will examine passage planning and navigation procedures across the operator's fleet, as well as the emergency response on the day. The final report will have to say whether this was one watch on one morning or a wider problem in how the company plans its voyages.
A little after 5am on December 27, the expedition cruise ship Coral Adventure was feeling its way toward Dregerhafen, about 100km east of Lae on the northeast coast of Papua New Guinea. On board were 80 passengers and 44 crew, partway through a 12-night voyage. By 5:25am the ship was on a reef, and the people aboard would stay on it for three days.
The Australian Transport Safety Bureau has now released a preliminary report on what happened. It points to a navigational error on the bridge. The chief mate had altered the ship's steering and speed, trying to adjust the planned route so the ship could make a smoother turn.
Then the navigation system froze while it ran a safety check. The pause caused the ship to miss the turn it had been routed to make. Trying to correct the mistake quickly, the chief mate switched to manual steering and raised engine power. The ship picked up too much speed and failed to swing to starboard in time. By that point it was travelling 2.5 knots faster than planned and sat 200m west of its routed course.
The chief mate returned to manual control, but the ship had already run wider than intended. ATSB chief commissioner Angus Mitchell described the conditions: it was dark, there were no navigational aids or lights ashore, and the chief mate reported being unable to visually identify the surrounding topography.
Mitchell stressed how little room there was to err. "It is a very narrow waterway," he said, adding that the margin for error in waterways of that kind is quite small. The ship ran onto the reef 160m east of its planned route. The underside of the hull suffered structural damage, and the vessel could not free itself.
For three days the 124 people aboard remained on the grounded ship. Afterward, all passengers were disembarked and taken to shore so that arrangements could be made for their return to Cairns. The report does not describe conditions on board during those days.
The ATSB attributes the grounding to a combination of navigation delays, changes in speed and confusion in the dark. The investigation continues. Mitchell said the bureau will review passage planning and navigational procedures across the operator's entire fleet, and will also examine the emergency response on the day of the grounding. A final report will have to say whether the problem lay with one watch on one morning or with how the company plans its passages.
