MOKPO, South Korea (AP) — It is a decision that has maritime experts stumped and is at odds with standard procedure: Why were the passengers of the doomed South Korean ferry told to stay in their rooms rather than climb on deck?
Evacuations can be chaotic and dangerous, and an important principle in maritime circles is that even a damaged ship may be the best lifeboat. But car ferries like the Sewol, which left about 300 people missing or dead when it sank Wednesday, are different. Under certain conditions — like those that confronted the Sewol — car ferries are particularly susceptible to rapid capsizing. This makes it critically important that when there is trouble, the crew quickly evacuate passengers, or at least gather them in preparation to abandon ship.
Though experienced, the captain of the Sewol, Lee Joon-seok, delayed evacuation for at least half an hour after the ship began tipping. Passengers, most of them teenagers on holiday, were initially told to stay below deck.
“If you would have not said a word to them, they would have left to the deck to see what was going on,” and a crucial step in any evacuation would have been accomplished, said Mario Vittone, a former U.S. Coast Guard maritime accident investigator and inspector. “They certainly made it worse than saying nothing at all.”
Lee has worked about four decades at sea, split between ferries and ocean freighters. A representative for his employer, Chonghaejin Marine Co. Ltd., told Yonhap News Agency that he has sailed the company’s route from Incheon, near Seoul, to the southern island of Jeju for eight years. A member of his crew, Oh Yong-seok, told The Associated Press that Lee worked on the ferry about 10 days per month.
After his arrest Saturday on suspicion of negligence and abandoning people in need, Lee apologized for “causing a disturbance” but defended his decision to wait.
“At the time, the current was very strong, the temperature of the ocean water was cold, and I thought that if people left the ferry without (proper) judgment, if they were not wearing a life jacket, and even if they were, they would drift away and face many other difficulties,” Lee said. “The rescue boats had not arrived yet, nor were there any civilian fishing ships or other boats nearby at that time.”
Vittone and Thad Allen, the former head of the U.S. Coast Guard, said that explanation misses a key point: The captain could have ordered passengers on deck, even if it was not certain that they would have to evacuate the ferry. Allen said in an email that two things needed to be done simultaneously: “Keep trying to save the ship but mitigate the risk to loss of life by preparing the passengers to abandon ship.”
Vittone said in an email that while an evacuation would carry risks, there would be no risk in gathering passengers at “muster stations,” designated areas the crew would identify during a safety demonstration early in the voyage. From these areas, crew members could make sure everyone had life vests on and then direct people to emergency exits.
“He could have always changed his order if the ship wasn’t sinking,” he said. “Worst case then would have been that he would have made his passengers suffer the inconvenience of standing around on deck for a few minutes.”
While it is not yet certain just what happened with the Sewol, car ferries can tip quickly because of what is known as the “free surface effect.” Water that collects on the car deck, which extends the length of the ship, can accelerate the capsizing as it sloshes around. This is not an issue with other ferries, whose decks near the water line are compartmentalized. Even a modest shift in a car ferry’s cargo could tilt the ship initially, and if water enters the car deck, the free surface effect could take hold.
Once the Sewol started listing severely, life boats were submerged on one side and equally useless on the other, where gravity held them to the side of the ferry. Passengers became trapped as the ship tilted so badly that walls became ceilings.
Following a pair of European sinkings in which more than 1,000 people died — the Herald of Free Enterprise in 1987 and the Estonia in 1994 — the United Nations’ International Maritime Organization studied car ferry design flaws as well as how best to evacuate vessels.
The changes, which included better escape routes and an evacuation analysis in the design process, applied to newly built ships. The Sewol was built in 1994, and thus was not subject to these regulations.
Car ferry crews should know that once the ship becomes unstable, a quick evacuation is essential, maritime experts said.
The head of the association that represents passenger ferries said he was puzzled by the lack of a command to head to muster stations, though he cautioned that a reasonable explanation may emerge.
“It’s important because in the case that there is an evacuation order eventually, people are prepared,” said Len Roueche, CEO of Interferry, a Canada-based association that represents the ferry industry worldwide.
Members of the Korea Research Institute of Ships and Ocean Engineering noted the problems with evacuating passenger ships in a 2003 study. Because passengers are unfamiliar with the often narrow and potentially complex passageways, “they may be confused in selecting evacuation routes: this could result in a delay in evacuation time and may cause some serious consequences,” the authors wrote.
The same paper offered a telling example of how even under favorable circumstances, evacuations can be far slower than anticipated. When a high-speed catamaran began listing in the English Channel in 1995, it took more than an hour to evacuate 308 passengers, although the seas were relatively calm and it was daytime. An evacuation drill well before the accident had taken eight minutes.
Under United Nations rules, crews have to conduct evacuation drills at least every two months. Because the Sewol’s route was not between nations, however, it would have been subject to South Korean regulations.
Ship owners are required to have emergency manuals for their vessels, coast guard spokesperson Kim Jae-in said, but he did not know anything about a specific manual for Chonghaejin Marine. Yonhap said it acquired the company’s manual and said the crew did not follow certain sections, including one that puts the second mate in charge of looking after injured passengers and setting off life boats.
South Korea requires regular safety education of crew members, and that passengers get a safety briefing when they embark. Its Seamen Law, provided by the Ministry of Government Legislation’s website, says the captain “must not leave the vessel until all of the cargo is unloaded or all of the passengers have left the vessel,” and “must do all his might to rescue the people, the vessel as well as the cargo when there’s an emergency.”
Allen, the former U.S. Coast Guard chief, said that whatever the rule books say, common sense dictates that as a situation deteriorates beyond salvaging, the crew needs to pivot from saving the ship to saving the passengers.
“If there was some period of time when they thought they could stabilize the boat, that is the best thing you can do for your passengers,” Allen said. “But the minute you think the ship is in danger, you have to act to get passengers to the boats.”

Following up this article.. 3 vice presidents of Tepco’s new Fukushima company are from nuclear makers / Mitsubishi, Toshiba, Hitachi GE [URL]
The government of Japan and Tepco are sticking to the policy “All Japan” to eliminate foreign capital on decommissioning Fukushima plant.
However, the 3 vice presidents of Tepco’s new inner company include a member from Hitachi GE nuclear energy. Also, the external advisory committee consists of the member from US or England. (cf, Only American representatives made default in the 1st meeting of international group for Fukushima decommissioning [URL2])
When Tepco established the new Fukushima company, it was actually only Areva that was eliminated from the stakeholders.
Mitsubishi Heavy Industries sent a vice president, but Areva, which is supposed to be in cooperation with Mitsubishi Heavy Industries did not send anyone to the board.
On 4/19/2014, a Fukushima worker replied to my pointing this out on Twitter and stated Mitsubishi Heavy Industries is actually wanting to quit being in cooperative with Areva quickly.
He didn’t add a comment on why.
Fukushima Diary has been following this worker for a long time. From his deep knowledge about the plant details and the situation, it is highly likely that he is involved in Fukushima decommissioning in real. (cf, Anonymous Fukushima worker, “Doctor diagnosed mycoplasma pneumonia, throat looked like gastric ulcer” [URL3])
You read this now because we’ve been surviving until today.
Un travailleur de Fukushima : “Mitsubishi Heavy Industries essaye de rompre ses liens avec Areva”
Le gouvernement japonais et Tepco restent au plus près de la politique du “tout japonnais” pour éliminer les capitaux étrangers du démantèlement de la centrale de Fukushima.
Or, les 3 vice-présidents de la nouvelle filiale de Tepco comportent un membre de Hitachi GE Nuclear Energy. En outre, la commission de conseils extérieurs est constituée de membres des USA et d’Angleterre. (cf. Les représentants américains font défaut dès la première réunion du groupe d’experts étrangers sur le démantèlement de Fukushima)
Lorsque Tepco a monté sa nouvelle société sur Fukushima, en fait seule Areva a été éliminée des parties-prenantes.
Mitsubishi Heavy Industries a mobilisé un de ses vice-présidents mais Areva, qui est supposée coopérer avec Mitsubishi Heavy Industries, n’a impliqué personne au bureau.
Le 19 avril 2014, lorsque j’ai soulevé ce point sur Tweeter, un travailleur de Fukushima m’a répondu en affirmant que Mitsubishi Heavy Industries cherchait à mettre rapidement un terme à son partenariat avec Areva.
Il n’a pas précisé pourquoi.
Fukushima Diary suit ce travailleur depuis longtemps. Il est très probablement impliqué dans le démantèlement de Fukushima en réalité, au vu de ses connaissances pointues sur la situation et les détails de la centrale. (cf. Un travailleur de Fukushima anonyme : “Le médecin a diagnostiqué une pneumonie à mycoplasmes, la gorge comme un ulcère gastrique”)
