Oooofff..that's a lot of flooding right there

That's a pretty new ship, latest news has the captain running the ship aground to prevent her from rolling-over.


Big gash, wonder how many compartments below the waterline got peeled opened...

Mixed-bag. Yes, older ships had more armor and torpedo bulges but, they also weren't dealing with missiles with shaped-charges that can impact your ship from various flight profiles, nor did they have any kind of defensive close-in weapons systems.

I was reading that a lot of these modern warships are more lightly built compared to the warships of WW2. During WW2 ships had to be armored to be able to endure naval gunfire from naval guns. Instead of heavy armor, modern warships more have to worry about missiles and have counter measures and weapons to protect themselves from the missiles. God Bless Smile


It depends. Ship building as a whole has advanced incredibly since ww2. Hull designers can imput everything into cad cam programs and determine exactly where ribs and bulkheads need to be, steel has gotten stronger and more consistent. In a lot of ways a modern ship with a thinner hull is a lot stronger for most of the issues a ship might face. Look at how modern cars fare in accidents these days. There are very few issues or dangers which the thicker hulled ships would be better such as puncture resistance. A design of a ship is a balance of compromises.

Improved Google translation of Norwegian news report.

KNM Helge Ingstad received several clear warnings from the tanker before the accident

The frigate KNM Helge Ingstad received clear warnings from the tanker Sola TS over the radio before the crash right into the front of the tanker. This is shown by the audio log that [newspaper] VG has received.

VG has published an audio log of the radio contact between the ships.

Fedje VTS is the Coastal Administration's watch center, which is responsible for the ships in the heavily trafficked fjord.

Three minutes before it strikes, the pilot on board the Sola TS asks the watch center which ship this is coming into the fjord.

Ten seconds later they answer:

"No, it's one, eh. I have not received any information about it. It has not reported to me. I just see it appear on the screen here," says Fedje VTS over ship radio.

Frigate came in at 17 knots

Radar images show that KNM Helge Ingstad goes south with 17 knots of speed, which equals 31.6 kilometers per hour. It had no deck lighting on, so it was hard to see, and it has features that make it difficult to detect on radar.

At the same time, Sola TS is coming up northwards at six knots.

The two ships are now on a collision course.

Fedje VTS to Sola TS:

"It is possible that it is Helge Ingstad. She came in from the north a while ago. It is possible that she is going there."

VG has informed the Armed Forces that they have sound logs and radar images from the accident. They do not want to comment on this.

"There will be a collision here."

So - one minute before the collision becomes fact - the tanker and warship have radio contact:

Without being sure if it's the frigate that comes against them, Sola TS asks if Helge Ingstad is coming towards them.

The warship confirms this five seconds later.

In the time that follows, the tanker asks the frigate repeatedly to change the course to starboard.

The answer from the frigate is: "Then we get too close to the shoals."

"Turn starboard if it's you coming. So you have ... ", Sola TS replies among other things.

Later, the tanker gives the following message: "Helge Ingstad! Turn!", before saying three seconds later:

"There will be a collision here."

The contact with Helge Ingstad will be sporadic after this, and with a lot of sound from the frigate's alarms. "We have given the alarm. Trying to get control of the situation", they say to the watch center, according to VG.

Although KNM Helge Ingstad before the collision had several radio exchanges with Sola TS, the frigate reports that they have collided with an unknown object and are adrift.

Then they ask for immediate assistance.

Disconcerting calls to get from assisting tugboat: "Helge Ingstad, there's bright light from your engine room."
