The Ever Given was refloated at around 9 p.m. Beijing Time and 3 p.m. Egypt time on the 29th, and with the help of a tugboat, it was successfully moved out of the river where it had run aground and sailed north, with the ships next to it sounding their horns in congratulations. The ship tracking data showed that the Chang Chi ship quickly reached a speed of 7.5 knots (about 13.6 km/h).

Evergreen Marine said that the vessel will first move to the Suez Canal Great Bitter Lake water anchorage for a ship’s seaworthiness inspection, the container ship’s subsequent voyage and cargo delivery will be subject to the inspection results of the inspection agency to make the necessary adjustments and arrangements. At present, there is no container damage or pollution notification, and the preliminary investigation excludes that the grounding was caused by mechanical or engine failure.

The technical management operator of the Changci ship, “Bespoke Shipmanagement” (Bernhard Schulte Shipmanagement), pointed out that the 25 Indian crew members on the Changci ship are safe and in good health.

As of yesterday morning due to the large blockage of the ship can not move a total of 367 ships, many other shipping companies choose to take a detour to the Cape of Good Hope, South Africa, adding 1 to 2 weeks of voyage and fuel costs.

The Suez Canal Authority said it will release 113 ships a day to absorb the congestion, which will take about three to four days to complete. After confirming that the canal’s channel had not been damaged by the long-giving vessel, traffic resumed last night and priority was given to three boats carrying cattle and livestock.

Experts say the next challenge is that all the blocked boats will arrive at the port almost simultaneously, and there may be no dock to dock and unload.

The global cargo trade suffered billions of dollars in losses every day during the nearly week that the Chang Chi ship was stranded.

With the Chang Chi ship out of trouble, the focus will now turn to investigating the cause of the grounding. While the strong winds of the sandstorm are generally seen as the primary cause, the Suez Canal Authority has also said that human or technical error cannot be ruled out.

One focus of the investigation is likely to be the two Egyptian canal navigators responsible for helping the captain navigate through, and whether there was any contact error.

“The New York Times quoted the founder of the maritime news website gCaptain.com website, is also the captain of the ship’s Conrad (John Konrad) pointed out that, because the long Chi ship flying the Panamanian flag, unless Egypt to exercise the right to take over the responsibility of the investigation, or Panama should be responsible for the investigation, but if the international pressure The National Transportation Safety Board (NTSB) of the United States may also be involved if international pressure is brought to bear to identify more complete responsibility.

Longchamp’s acceleration before running aground was against the normal driving pattern

The vessel is a 20,000 TEU class container ship, not owned by Evergreen Marine, but rented from The Japanese shipowner “Shoryu Kisen Kaisha Co. “The ship was registered in Panama, and the ship belongs to Panama.

Central News Agency reported that a number of senior shipping industry in Taiwan have access to automatic identification system (Automatic Identification System, referred to as AIS) information, record “Chang Chi ship” before the grounding of the driving dynamics.

Senior shipping industry sources said, from the AIS can clearly see the “Changci ship” into the Suez Canal after the left side of the stick, then speed up significantly, and then to the right, and then back to the left, and finally horizontal grounding, general ship navigation speed in the river about 8 to 9 knots, “Changci ship “In the 40 seconds before the grounding, the speed of the ship accelerated from 8 knots to the highest 13.7 knots, which is against the general driving norm.

Senior shipping industry analysis, “Chang Chi wheel” may be the ship began to deflect in order to correct the path and finally out of control, because the shallow water effect will make the ship more bad manipulation direction, large ships can not risk deviating from the middle of the channel.

The automatic identification system is an automatic tracking system installed on the ship, through the exchange of electronic information with neighboring ships, AIS shore station and satellite equipment, can supply AIS information to the maritime radar, priority to avoid collision accidents in marine traffic, but also can broadcast walrus information, danger warning area, for the ship to receive, to enhance navigation safety.
