Grounding of a

container ship

A case study


2/13

Narrative

A 25,000 tonne container vessel was approaching port

following a short coastal passage.

The bridge team consisted of the master, the OOWand the helmsman.

Master had the con.

OOW was plotting the vessels positions on a paperchart using only GPS


3/13

The approach to theport required the vesselto enter an inlet several

miles wide and thenalter course into a bayin which the port waslocated.


4/13

The masters plan.

It was a warm and calm day with slight haze and no

significant tide.

Engines were on stand-by and speed reduced to 14kts.

Master intended to alter course by 40by putting the

wheel over some distance before the alteration point;however he did not advise the OOW of hisintentions.


5/13

At the chart table, the OOW was in the process ofchanging charts and was transferring the vessels positiononto the new chart.

The master called out to ask him if the vessel was 0.5miles from the alteration point.

The OOW, presumably not wishing to point out that he hadnot put down the position on the new chart, replied yes.


6/13

The master accordinglyordered the helmsman

to bring the vessel tothe new course.

The OOW plotted theships position on thenew chart using GPS

and realized that theyhad altered too soon.

The ship wasproceeding at 14 kts

towards the shallows.The OOW alerted the

master.


7/13

The master observed thesouth cardinal buoy onthe starboard bow which

he had expected to be onthe port bow.


8/13

The master immediately ordered the helmsman to put the wheel hard to starboard

Hard a starboard!


9/13

The vessel had juststarted to swing whenshe ran aground.

The vessel spent 24hours aground beforebeing pulled off bysalvage tugs.

Fortunately the bottom in

that area was soft mudand the vessel was foundto be undamaged.


10/13

DiscussWas the passage plan adequate?

Was the bridge team following correct bridgeprocedures?

Did the master and OOW share a commonmental picture?

Was the masters question regarding vessels

position appropriate?Was the OOW assertive enough?


11/13

Lessons learnt

What can we do to avoid an incident like this?


12/13

NO GO

w/o

Mark no-go areas

Use all available meansfor position-fixing.

Use parallel indexing formaintaining track

Use CRT for accurateturn in restricted waters.

Use P.I. for monitoringarrival at w/o position.

Use clearing bearings to

avoid dangers.

Brief the bridge teamabout intended passage.
