Take the case as a result of the outline of the ship's out of balance. Where is the road in the flood season?

1. Accident description

At 0531 on September 6, 2013, the "E" wheel carrying the 1045 tons of glass board was turned over during the operation of the original Chongqing Port Construction Terminal (about 669.5 kilometers). Three people died and 1 disappeared.

Second, the unsafe behavior of the accident exposure

First, the goods are not reasonable. The size of the glass plate contained in this round is large (3.66-4.20 meters long, 2.44-2.74 meters high, and 0.005-0.012 meters). The complete stability does not meet the requirements of the ship's inspection specifications; the bottom end of the outermost glass plate and the cargo compartment fence have not been filled, and the front and rear Glass glass plates have about 0.4 meters. There is about 0.4 meters of gap between the bottom and the front and back walls of the cargo cabin. After each A -type frame is loaded, it is bundled with a steel belt and does not fix it with the hull.

The second is that the operation is improperly operated, and the ship and the dock have repeatedly touched. After the first carried by this round, it dripped, and then carried out the second berth at a larger angle, and hit the shore wall of the dock three times in a row (the first impact caused the depression of the side plate of the boat on the spot, Step side shift, the hull tilt right; the second and third impacts once again triggered the cargo cabin glass plate to dump the shift towards the stomped side), and finally the ship rolled quickly to the right after the cable was stretched.

Third, the safety management of the ship company is not in place. The company's light ship lease the "E" wheel, but does not implement daily safety management of the "E" round. Instead, it is managed by the king of the ship owner. , Tracking and assessment measures; the sea and machinery executives hired by the company all served as crew members on another ship belonging, and are part -time safety managers.

Fourth, at that time, the water level, dance, berth at a specific time and neighboring berths were berth, and it had a certain impact on the "E" shipping operation. At the time of the incident, the upper end of the dock was relatively urgent, with cold bubbles below, and the water potential was complicated. The M "wheel, coupled with about 152 ° angle at the front of the downstream of the berth line and downstream, has a certain impact on the berth operation of the" E "wheel; , Dynamic judgment and cable operation.

Third, accident lessons

(1) Need to accumulate and tie the goods correctly to prevent the root cause of "congenital shortcomings"

In this accident, the glass plates contained in the "E" wheels are large and heavy, and the horizontal accumulation makes the center of gravity of the goods higher and the stability is worse. There are major hidden safety hazards of dumping and shift during ship navigation, mooring and operation. The stability is the role of ships to resist various interior and external crossing torque to ensure that there will be no excessive horizontal inclination and not overwhelming performance. The first is the initial stability height (GM). Generally speaking, the GM is larger when the ship is carried or carried by the carrier, and the GM is smaller at full load. The GM GM with a higher GM with a higher center of gravity in passenger ships, deck cargo ships, container ships and other center of gravity is relatively small. The "Legal Inspection and Technical Rules of the River" stipulates that "the height of the ship's initial stability should not be less than 0.2m". Once the GM is lower than 0.2m (or even negative), it will be difficult to recover when the ship is tilted, increasing the possibility of horizontal flipping possibility Essence In addition, the purpose of the cargo system is to prevent the cargo move in the cabin before the ship loading, transportation and uninstallation. The horizontal movement of any cargo will directly break the ship's balance and significantly increase the horizontal leaning of the ship. Therefore, crew (especially the crew loading major shipments, passenger ships, deck ships, container ships, etc.) should be carefully formulated in accordance with the cargo conditions and the technical conditions of the ship before each loading. After the shipping company reviewed and agreed, confirmed the safe loading method with the dock, urged it to operate in accordance with the agreed manner, and avoid blind loading to reduce the height of the initial stability and buried the hidden dangers of the accident. During the navigation, mooring, and uninstallation process, the goods will not slip, preventing the freight from moving the goods from leaning.

(2) Pay attention to the dock of docks during the flood season to prevent blind operations from causing danger.

The waters of the accident are located near the dock of the flood season. The water potential is complicated, and there are already ships in nearby berths. In addition, there is a large angle between the planned berth and the nearby river channel. The operation puts forward higher requirements. The "E" rotary driver did not carefully observe the waters of the waters of the pier after the first downshion. Instead, he blindly chose the second dwelling, which was an important reason for the ship to touch the dock three times and trigger the displacement of the goods. The fluctuation rate during the flood season has increased significantly compared with usual, and the water level rises frequently. In addition, the water flow is jointly affected by the underwater structure of the riverbed terrain, river direction, and pier. Water conditions, and the dock's separation operation is closely related to the condition of mooring ships in adjacent berths (such as ship width, captain, etc.). If the crew is improperly operated by the separation, accidents are prone to accidents. Therefore, the crew must be highly alert to the potential safety risks of the waters in the pier in the flood season. Polling, large angle or too fast berths cause danger. In addition, the dock should provide safety and beeping conditions to Hong Kong ships in accordance with the relevant technical opinions of maritime affairs, channels and other departments, and formulate ship dispatching schemes under different conditions in accordance with cutting -edge hydrological, meteorological conditions and operating ships. Commanded ships enter the port to ensure that the ship is safe and berth. (3) We need to strengthen daily safety management to prevent hidden dangers from lack of main responsibility

In this accident, the company's belonging to the ship of the company's ship was leased, but the daily management was not implemented. The safety management of the ship was still carried out by the relatives of the people. Lack of cargo accumulation of knowledge and blind loading; the incident of the incident, the ship is temporarily hired in the waters of Zhongxian Water, but the company has not implemented training, tracking, and assessment measures for new crew members; On a ship as a crew, a non -full -time shore -based managers cannot effectively fulfill the responsibilities of shore -based management. The lack of responsibility of a series of subjects has led to long -term "blank" of ship safety management, which eventually "promoted" the result of the ship destroyed. The "Safety Production Law" stipulates that the main person in charge of the production and operation unit must organize and implement the unit's safety production education and training plan, and requires that the production and operation units shall ensure the implementation of the safety production responsibility system; Clarify that the owner or operator of the ship should strengthen the safety management of the ship and be responsible for the safety of the ship's traffic; Essence Therefore, the ship owner/operator/operator/light boat lessee/actual controller shall strictly follow the laws and regulations such as the "Regulations on the Safety of Safety", "Regulations on the Management of Inland Traffic Safety", and "Regulations for Safety and Prevention Management of Shipping Companies" to carefully carry out education Training, crew employment and other management work, fulfilling full -time safety management responsibilities such as sea/machinery, and effectively implementing the responsibility of the main body of production safety.
