Lessons from accidents
Every rule at sea was written after somebody died. These are the accidents behind the rules, taken from the official investigation reports and retold in simple English: what happened, why it happened, and the one thing to remember on your own deck. No drama, no blame beyond what the investigators found, and the source named at the end of each page. The first group is about language itself: crews that could not talk to each other, to the pilot or to the passengers, and what that cost.
How to read these pages
- Read the story first, then the causes. The story is short. The causes are the part the investigators spent a year on.
- Words in this case. Each page starts with the five English terms the report turns on, with a one-line meaning. They are the words recruitment tests and interviews ask about.
- The lesson is one sentence. If you remember nothing else from the page, remember that.
- Three questions at the end. They are the same kind recruitment knowledge tests ask, and they also appear in the knowledge test on this site.
- Read more. The full report is public. If the case touches your ship type or your rank, it is worth an evening.
Communication and English
Fire on a ferry at night. The crew could not talk to the passengers, or to each other.
On the night of 6 to 7 April 1990 fire broke out on the ferry Scandinavian Star between Oslo and Frederikshavn. It spread through the accommodation in minutes. 158 people died in the fire, most of them in their cabins and in the corridors trying to find a way out.
The pilot and the master did not understand each other in the fog. The ship hit the bridge.
On 7 November 2007 the container ship Cosco Busan, leaving Oakland in thick fog with a pilot on board, struck a tower of the San Francisco-Oakland Bay Bridge. About 200,000 litres of fuel oil spilled into the bay. Nobody was hurt; the bay's birds and beaches were.
The officers gave orders. The crew did not understand why. The ship exploded.
On 28 February 2004 the chemical tanker Bow Mariner exploded and sank off Virginia while the crew was cleaning cargo tanks that had carried a flammable chemical. 21 of the 27 people on board died.
Watertight integrity
A ferry sailed with the bow doors open. Nobody on the bridge knew.
On 6 March 1987 the ferry Herald of Free Enterprise left Zeebrugge with her bow doors open, took water onto the vehicle deck and capsized within minutes just outside the harbour. 193 passengers and crew died.
The bow visor broke off in a storm. The car deck flooded and the ship went down in the dark.
On the night of 28 September 1994 the ferry Estonia lost her bow visor in a Baltic storm between Tallinn and Stockholm. Water flooded the vehicle deck, she listed, capsized and sank within about an hour. 852 people died; 137 survived.

Sources and the way we write
The facts on these pages come from the official reports: dates, numbers, causes and findings. The words are ours, written for a seafarer whose English is a working tool, not for lawyers. We do not quote the reports, name crew members or add anything the investigators did not find. Where a report is online at a stable address, the link is on the page; where it is not, the authority and the title are enough to find it.
19 cases so far. The section grows with new reports; if a case from your own experience should be here, tell us.
