AMP BEGINS INVESTIGATION FOR EVENT AT THE EVER GIVEN CONTAINER PORT IN THE SUEZ CANAL
MARCH 25, 2021
The Panama Maritime Authority (AMP) after receiving the information on the stranding of the ship Ever Given, in the early hours of March 23, 2021, began an investigation of the events that occurred to the container ship in the Suez Canal, in order to determine the possible causes of the accident, reported the general director of Merchant Marine (DGMM), Rafael Cigarruista.
Preliminary reports indicate that the EVER GIVEN ship, with IMO number: 9811000, belonging to the Panama Ship Registry, at approximately 5:40 am (UTC) when it was transiting through the Suez Canal, despite strong winds and a storm of sand, with two pilots on board (starters in Suez), suffered problems in his machine that affected his maneuverability.
The reasons for his grounding have not yet been determined. So far there is no contamination or injuries, only some structural damage to the ship.
The Ever Given is one of the largest container ships in the world, built in 2018, it is 400 meters long (length), about 59 meters wide (beam) and 15.7 meters deep. It can transport a total of 220,940 tons and has a capacity of 20,388 standard-size 20-foot containers.
By having these dimensions, the container walls act as sails and the ship can be subject to gusts of wind.
The Panamanian Registry expressed its concern from the first moment about the condition of the ship and is looking for the best way to solve this situation, taking into account the strategic importance of the place where the incident occurs.
For this reason, the DGMM’s Research and Maritime Affairs Department (DIAM) team is in constant contact with the ship’s operators and with the Egyptian Authority for Maritime Safety (EAMS).
The AMP is in full collaboration with international authorities, thus complying with the provisions of the Code for the Investigation of Maritime Accidents and Events, which indicates the joint participation of the States with an interest in the investigation of any maritime accident, with the sole The objective is to clarify what the causes were and thus be able to issue recommendations to prevent accidents of the same nature from occurring in the future.

Ever Given were ship no 13 in a convoy of 20. At least 15 ships entered the canal and faced the same whether. Ever Given run aground, bu the other 14 ships had no reported issues. The weather could not be the main reason to the grounding. Some people are talking about bank effect, but when bank effect strikes you are never in doubt. The Suez Canal is design with a flat bottom and sloped sides. This means that there are not any bank present. The main problem is the design of the stern of the ship. The stern is a flat sloped bottom with a very small rudder. The stern makes the ship to be directional unstable and very difficult to handle at slow and medium speed. With stopped engine she will not respond to rudder at all. I have worked to solve problems with directional unstable ships since 1980. I have teach Captains and Mates hove to handle those ships and explained why those ships behave as they do. As a result of this knowledge i have Patented a new way to design ships to avoid directional unstable ships.
Good Day – Your comment is well received. While your opinions are well noted, you are encouraged to review the linked article (https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.1019.9173&rep=rep1&type=pdf). As noted, “…Obviously, there
are many more arrangements and also the sloping banks may be different inclinations. All of these factors may influence the suction force and yawing moment.”
With regard to the stern design of these vessels, we await the final incident report from Panama and/or Egypt. Please note however, that many vessels require good flow across the rudder to maintain steerage – particularly at low speeds.
