Reasons for allision investigated

Uncontrollable high speed was the main reason for the allision of the 'Milano Bridge' in Busan with a whole strip of container cranes on the dock on April 6. Apart from the speed, less reaction time after turning, less power from tugs due to high speed forward and no effect of bow thrusters was stated by the investigators of ONE as the possible causes. The crew had not taken into account that the ship was empty and sailed with a partially submerged rudder, nor had they taken sufficient account of the local weather conditions and had not understood the pilot's intentions whoo panicked as the ship approached the dock. Only one of the six gantry cranes remained functional after the accident. The South Korean authorities have discovered the cause of the accident. Too high speed in combination with a propeller that partially rose above the water surface, making the vessel more difficult to control, the Korean Maritime Safety Tribunal of the Ministry of Oceans and Fisheries pointed to as the causes of the incident. The ship entered port with about a third of the propeller above the surface, because there was not enough ballast water on board. The carrier also did not carry any cargo, because it was on its way to a Chinese shipyard for repairs. In addition, the "Milano Bridge" approached the quay at a speed of eight knots, which was higher than the usual speed of six knots when mooring- Based on available data, statements from crew and images of the accident, the investigators attempted to simulate the conditions as they were at the time of the allision. This revealed, among other things, that when the propeller is completely under water, the ship is easier to steer, which considerably reduces the risk of an incident. Calculations by the investigation team also show that if the speed was less than seven knots, the accident could have been prevented. The 'Milano Bridge' has arrived in Chang Xing Dao Port, Dalian, on May 5 at 7.30 a.m. for repairs.

Container ship caused crane collapse in Busan

At the new port of Busan the 'Milano Bridge', under the conduct of a pilot, allided with the container cranes 81, 84 and 85 during cargo oprations on April 6, 2020, at 2 p.m. LT at berth 7 of the North Terminal International Terminal, while approaching berth 8, coming from Shanghai. The 44 year old operator of crane 85 managed to jump from a height of 5 meters to escape and suffered minor injuries to the ankle and was treated in hospital. The impact caused crane 85 to collapse, and the cranes 81 to 84 were pushed off the rails and could no longer be moved. Crane 81 was also at risk to collapse. Before the allision, the container ship also came in contact with the 'Seaspan Ganges' at berth 7. It was expected that it would take 18 months to replace the gantry crane No. 85 and 3-5 months to get crane 84, which was pushed out of the rails, back to working condition if there was no major damage to the structure. In addition, the cranes 82 and 83 did not seem to have suffered major damage. The Busan Coast Guard was investigating the cause of the accident. On April 7 at 8 a.m. the ship could finally be berthed at the Hanjin NewPort Container Terminal. The lashing bridge structure was broken off and missing; port side upper deck plating was deformed; handrail on port side and starboard side upper deck plating were buckled and deformed. The vessel shifted to Busan anchorage on April 8.
