Talk:Sinking of MV Sewol

Ideas for clarification

References to the bridge need to be made consistent. The bridge is referred to as ‘the steering room’, ‘the helm’, and ‘the bridge’. The duties of the Third Mate and the Helmsman also need to be clarified. The Third Mate is variously described as ‘guiding’, ‘steering’, ‘monitoring the radio and radar’ and ‘commanding’ while the Helmsman is variously described ‘directing’, ‘turning the ship’ and confusingly that he ‘turned the ship 3º to starboard……’. It is also unclear what the permanent captain’s advice regarding steering or helm restrictions were.

The bridge is where the ship is navigated from. The control for steering the ship is located on the bridge as are the navigation instruments and displays the ship’s short range radio communications and the main engine speed control or telegraph for relaying engine orders to the engine room.

At sea the bridge is manned by the officer of the watch (OOW), which would in this case be the Third Mate. There should also be a lookout and if the ship is being steered by hand, a helmsman. The Captain will normally be on the bridge during critical times of the sea passage, for entering and leaving port and for docking and undocking.

It is unclear from this entry if the ship is in automatic pilot or in hand steering. If the ship is automatic pilot the OOW would normally, although the lookout may, change the set course on the auto pilot. The automatic pilot will automatically change to a new course setting within the limits and maximum rudder angle set by the OOW and steer a course with the accuracy and using a maximum angle set by the OOW, If the ship was in hand steering then the OOW would tell the helmsman what course to steer or could give wheel orders telling the helmsman what angle of rudder to apply. The helmsman may also be instructed not to apply more than a given rudder angle.

The OOW would not normally steer the ship but would conduct the ship by monitoring the ships position and other shipping by use of the navigation equipment and radar and by listening to the short range radio.

The entry needs to clarify whether the ship is being steered by the helmsman or is in automatic pilot, also what type of orders were given on each occasion that course changes were made (i.e. orders for a specific course to be steered or wheel orders for a specific rudder angle to be applied) and what the advice of the permanent captain was with regard to steering; for example it may have been that above a certain speed a certain rudder angle should not be exceeded. — Preceding unsigned comment added by Simon JD (talk • contribs)

Radians per second

In the article, it is mentioned that the vessel reached angular velocity of 2 radians per second, which cannot be correct. A full round is 6.3 radians. I cannot verify the source to the given numbers, since it is in Korean, but I suppose degrees per second is the correct unit. Atteaalto (talk) 08:33, 16 February 2021 (UTC)

Atteaalto, You are right. The source "선박자동식별장치(AIS) 신호정보에 따르면 세월호는 4월 16일 오전 8시 49분 13초부터 초당 0.29도, 0.83도, 1.0도, 2.0도로 선회 각속도가 차츰 빨라졌다" is translated as "According to the signal information of the automatic ship identification system (AIS), the Sewol ferry's turning angular speed gradually increased from 8:49:13 am on April 16 to 0.29 degrees, 0.83 degrees, 1.0 degrees, and 2.0 degrees per second".―― Phoenix7777 (talk) 09:09, 16 February 2021 (UTC)

Yes but we know that is not credible or reliable because it comes from Korea. 2001:56A:7D81:BF00:83AA:85A0:F296:CD0B (talk) 11:55, 19 May 2023 (UTC)

The 31st MEU

While we didn't get to launch any water craft to aid in rescue efforts, we did have a helicopter divert as soon as it happened, with another joining after about half an hour. The first arriving at 09:02 and the second at 09:28. Just in time to get harassed by the KCG. It wasn't just fishing boats. We helped rescued 16 before the South Korean Navy forced us to leave and stand-by with our Johnsons in our hands while they fouled this up gloriously and got sailors killed. Get your facts right. I got called on the carpet over this bs. Off-Handed Barrel (talk) 16:30, 27 June 2023 (UTC)

"side ramp"?

The article says "The regular captain of Sewol, Captain Shin, had warned Chonghaejin about the decrease in stability and attributed it to the removal of the side ramp". This sounds like the "side ramp" should have been discussed earlier in the article, but I can't see anything about it. (The word "ramp" only appears once in the article) KarenSutherland (talk) 18:06, 8 August 2023 (UTC)

Deathtoll

"Out of 476 passengers and crew, 306 died in the disaster"

Shouldn't this be reworded? It says the deathtoll was 299 passengers, and the other 7 were divers and emergency workers, not passengers or crew. 49.182.143.236 (talk) 12:54, 20 September 2023 (UTC)
