The Costa Concordia  ship's AIS Vessel Traffic records released by Turkish Maritime News web site, www.denizhaber.com.

According to the published route, ship, inexplicably, seems to have followed a very dangerous route.

According to www.denizhaber.com; the following issues clearly seen in the ship's route from Civitavecchia till the site of accident:

After moving to Civitavecchia'dan ship followed on the normal route.

This route is kept clear from the shallows, leaving the island of Giglio on the Port side, passing the channel  between Giglia and  mainland of Italy route. At this stage, Costa Concordia followed a route of 298 degrees.

However, in a distance 7-8 nautical miles from the Channel between the island and the mainland of Italy, the ship made a course alteration, up to 20 degrees by altering the course to 20 degrees to port side,, This course alteration has no sense, because it obviously made the vessel heading to the Giglio Island. Lets make an estimate: The ships bridge wanted to give a close berth to the Island.. There is no other explanation. We cannot talk about a rudder failure since ship seems steering good. Made a good course change.

Electronic equipment? Anybody could see the island was ahead of the ship. A good lookout is essential no matter you have the most advanced electronic equipment. .

Finally,  the ship passed close to the rocks at the east side of Giglio Island.

The web site asks: Why the giant ship passed so close to these rocks very close to the Island? What made ship to go there, and if that was due to a failure, why the passengers were not alarmed in due time?

And as tha captain declares that he tried to steer the ship towards the Giglio Pier, ıt cannot be due to a rudder failure.

If there is not a rudder failure, and the ship is steerable, the major question still remains:

"Why such a big ship passed so close to the  rocks?"

If this is correct, the maritime route to the AIS in terms of technique that will have emerged to explain the many points that are in need.

Experts: "GOOD INTENTION,BAD MANEOUVERING SKILLS"..

Experts commented the Costa Concordia disaster at Turkish online maritime portal www.denizhaber.com . Experts agreed on that Captain Francesco Schettino had the goog intention to give a close berth to Giglio Island; but however, Captain's professional skills was not capable to support the scope of this intention.

Tradition Fine, but how about maneouvering skills?

DenizHaber'e maritime experts who commented on the subject, said "a beautiful tradition, but not the same for Captain's skils " in the form of summarized events.

Experts agreed on the good intention of Captain Francesco Schettino's good intention to pass very close to Giglio island-as his predecessors used to do.

But, on the other hand, the rocky shores and rocky sea ground close to the island required expert maneouvering skills, they said.

Was SQUAT accounted for?

According to experts; "Such ships has a draught of about 8 metres, but however, as the ship gets underway, she also "squats". Effect of the squat increases as the ship's speed increase. It might be as much as 3 metres as the ship gets underway up to 15 knots. Effect of squat further increases at shallow waters. Most of the captains either does not know or does not account the effect of squat at restricted waters. This might be the case for Captain Schettino, because he was quoted as saying that the rock should not be there. May be the rock should be there but not the ship. Because it was ship's draught was increased; it was not the waters shallowed" experts said.

Experts also pointed out that electronic equipment was not only be relied upon to navigate in such constrained waters. "The captain could maneouver by his local knowledge at such restricted areas, there is no time to look at electronic equipment and take a decision. Ships drift due to course alterations, even centimeters are important, and squat is also important if the ship's speed is over 5 knots. Therefore, usually such areas are pilotage areas. What taught at schools- even before right is starboard and left is port- is the proverb "SAFETY IS AT OPEN SEAS". The course alteration to Giglio island for a salutation three long is therefore a big risk for ship's safety" experts quoted.

Experts also of the opinion that if there was not a strong rudder alteration to starboard, the gash on the starboard side would be not that effective, if did not happen at all.

Here's Vessel Traffic on the discussions on the subject ...

  • COSTA CONCORDIA 'route .. The accompanying illustration of the accident records of the ship entering the AIS area. Ship route when traveling to the island at the last minute maneuver to starboard and made the difference, at a rate slower than the island where the rocks in front of them as you pass through the shallows in front of the port is damaged and still continue evacuation operations we can say that.
  • Vessel Traffic in the accident last night, many hours since the ship continues to drain.5 different ships at the same time, Monte Argentario'ya connection to the mainland (about 10 miles east of the island experienced an accident) are doing relief ..
  • Ship Traffic In the meantime, I should mention that the AIS receiver stations in the region do not have the amateur. Therefore, this region www.gemitrafik.com live from there as the opportunity to follow up. But developments in the services I get paid to share with you ..
    · Like about an hour ago.
  • Ship is probably due to an autopilot failure and shift errors experienced this accident ..
    Civitavecchia, because from the first stop out of the ship's normal route of going through the Giglio island Savona'ya no ..
    22:04 last night the ship up to 298 towards actu-ro ... (which is the correct route to Savona'ya, with islands that do not impede the passage of a route to the right ..) What happened to all returned to the pier is approximately 20 degrees and 279 to ilerleyeme started right .. This route is a route directly to the center of the island of Giglio! ..Therefore, this change can not be made ​​an officer, not at a distance .. From this point of the island from the full 10 miles ..
    22:42 up to continue on this route is, 1-mile distance to the island all the way until the .. 15.3kts still speed ..
    At this point, and speed 6.6kts 292'ye translated up to the fallen ..
    Probably 'cause so close to the island fell into the "panic experienced on the bridge ..Probably the cavalry invited blah blah ..
    But I was wrong to think this koşturmacada save them to go parallel to the island, because immediately prior to the harbor of the island of Giglio has a serious rock-shelf region .. (The above map shows in detail ..)
    Here is a little dark after this point .. Because the news of this rocky region to the captain and the ship struck something before trying to enter into the port of Giglio writes urgently .. Logically you definitely can not beat a ship of this size would normally spend in a rocky region has instilled wanted to seem like a shortcut route to port ..Interestingly, over the course of the ship, but up to this point .. there is no shallowsThe shallowest point is 118m around the .. my interpretation is thus very close to the island find themselves looking at other things for the panic passed reluctantly from the rocks and they are therefore led to a serious damage to the ship in the direction of rubbing rocks ..
    Already among the rocks at the port after the ship's drift towards advanced in front of them .. passing through the cliffs seem to have experienced a serious problem that is real ..
  • Ship traffic is still in the news caused "serious electrical fault," they say .. autopilot, control, and so on. there is a fault related to the intervention could not be certain why, but 10 mph along the way, why not head into some went to the island ..
