The Panama Maritime Authority (AMP) reported that it has concluded with the investigation related to the collision between the MT Sanchi vessels, which is in Panama, and the MV CF Crystal, registered in China. The fact goes back to Saturday, January 6 when, after the incident, there was an explosion and sinking of the Sanchi ship about 160 nautical miles east of Shanghai.
In the investigation, the States with interest, the People’s Republic of China (Hong Kong), the Islamic Republic of Iran, and the Republic of Panama collaborated fully. The Vice-Consul of Panama in Shanghai, Nehemiah Jaen, the Chief of the Technical Office of Segumar of Tokyo, Samuel Guevara, and the accident investigator, Captain He Tong, headed the delegation sent by the Republic of Panama, the People’s Republic of China so that, in representation of the Bandera State, they participated in the coordination and planning meetings that were held jointly with the Accident Investigators of the Maritime Authority of China and the Maritime Bureau of Iran.
Vice-consul Jaén said that the presence of Panama was aimed at conducting a safety investigation to determine the main causes that could be the root of the collision, in order to achieve recommendations and lessons that can improve maritime safety through of mandatory regulations that can prevent a similar tragedy in the future.
In addition, the Panama Maritime Authority (AMP) had the collaboration of the team of the Japanese company Nippon Kaiji Kyokai, commercially known as ClassNK, for the analysis of data from the Voyage Data Recorder (VDR). To establish the conclusions, there was the intervention of 21 experts who were part of each of the States of interest, which exchanged and analyzed in detail the information generated by the marine incident, which was valuable to establish the possible causes of this accident. It should be noted that the Assistant Secretary General of the International Maritime Organization (IMO), Lawrence D. Barchue, participated.
Conclusions The ship Sanchi as the ship CF Crystal, did not comply with some Regulations of the Colreg (Collision Regulation) International Convention on the prevention of collisions, which did not consider prudent regulation 5 and regulation 7, in addition, both ships were not aware of the change in navigation of one with the other. The navigation guard personnel of the ship CF Crystal had not noticed the presence of the ship SANCHI until the moment of the collision, this also that the MV CF Crystal the AIS was as the only aid to navigation to avoid the collision and the It was not used correctly either to identify the neighboring ships that were in the area. The alteration of the course of the CF Crystal to starboard, beginning 15 minutes before the collision, developed the situation that would otherwise have been evident in a collision.
There was a difference of 20 to 25 degrees of the Course over Ground (COG) and differences of 2 to 3 knots of speed of the Speed over Ground (SOG) between the information of the AISD of the Sanchi received by other vessels and the reading of the Video Data Recorder (VDR). ) of the Sanchi. To reach these conclusions, the data obtained through the Voyage Data Recorder (VDR), a mandatory equipment that must be installed on all passenger ships or ships of more than 3,000 tons, was decisive. The VDR, is a system of recording and storage of data for boats able to collect information of the different equipment that is in the navigating bridge of the ship during a voyage, it is comparable to the denominated “Black Boxes” used in the airplanes.
The data obtained through the VDR, both of the Sanchicomo of MV CF Crystal, added to the information and tests achieved in the field, was first analyzed separately by the technicians of each State of interest, later through the Second Round of Meetings, each State of Interest contributed to the investigation is part of the analysis carried out, to the evidence and evidence obtained, in order to deliberate and arrive together in parallel to a single conclusion.
