On the afternoon of the 24th, Beijing time, it was reported that a freighter from Taiwan in China ran aground on the Suez Canal, which blocked the canal and affected the navigation of subsequent ships. Oil prices rose accordingly. At present, this accident has brought certain impact on international shipping and trade. So what rescue measures are available in this kind of shipping accident that can reduce the losses of all parties the fastest and to the greatest extent?
Judging from the situation at the scene, the bow was pushed from the front side until the bulbous nose was all inserted into the embankment of the river, and there should be structural damage. Fortunately, there is no fuel tank in the front car, so there is no pollution at present. The positions of the fuel tanks of the Long-Civil Steamship are currently safe, and the slop tanks are also safe so far. Therefore, its pollution to the marine environment is limited. Regarding the rescue method, the common use of tidal floatation is difficult. The current tide range of the canal is two meters, and the bow of the long-sending ship has a large area on the shore, which reduces the drainage and the difficulty of floating. However, the containers stacked on the Longsong Class A are nearly ten storeys high. The current common barge cranes cannot reach that height. Unless a special large crane is used, and the spreader for lifting the container can only be used, but the degree of automation is low. , Not a few days the bow can not be unloaded. Change the attitude of the ship by pressing the water. After looking at it, they should have taken the posture of the ship, because the stern waterline of the ship has been submerged, indicating that the bow ballast water is now empty and the stern is under pressure. However, the ship is basically fully loaded, with little adjustable ballast water, and the stern rich water depth is limited, so this method can only assist and cannot be successfully rescued. Dredging is the most reliable method, because there was a boat dredging the river not far north of the incident, but there was a problem that the soil under the bow was difficult to dig out. And the common reamer can damage the hull of the ship. However, the Suez Canal was built in the desert, and the riverbed is mostly sand. If high-pressure water is used to impact, this will wash the soil around the hull, and the water flow in the Suez Canal is relatively rapid, which can assist the soil erosion. After the ship is completely floating on the water, use the tug to straighten the posture and tow it back to the anchorage.
