Hudong Zhonghua completes emergency repairs of "China Sea Mars"

On March 29, after 7 days of continuous operation, Hudong Zhonghua, a subsidiary of China State Shipbuilding Corporation, successfully completed the repair work on the rudder system of the “China Shipping Mars” 14000TEU container ship of COSCO SHIPPING Container Transport Co., Ltd. The ship was built by a South Korean shipyard, and the rudder bearing of the rudder system before the Spring Festival failed, causing the ship to stop operating. In a difficult emergency, COSCO Shipping's first call for help was to build a strong Hudong Zhonghua. Hudong Zhonghua lives up to its trust, high-quality work quality, fast repair speed, and urgent work attitude of customers, which are highly praised by COSCO Shipping.

In mid-February, COSCO Shipping sent a letter to the company asking for help. Anxious customers, it is always Hudong Zhonghua's service tenet to consider the interests of customers. Although there are many objective difficulties, Hudong Zhonghua has not hesitated to take up this task. Hudong Zhonghua has withstood the pressure of the epidemic, and plans to complete the 14-day maintenance project in 7 days. The shipowner is very satisfied with the various acceptances and praises Hudong Zhonghua's tenacious hardworking spirit and strong technical strength.

If you wait another day, the owner will lose another day. Due to the docking period and other reasons, it is not possible to perform docking maintenance. Hudong Zhonghua formulated a bold plan. After the ship docked at the dock, the ballast water was beaten, and the rudder blades of the crotch were exposed above the water surface for 3m.

The second part of the general assembly undertaking the repair task was the first time to replace the rudder bearing at the terminal. The department analyzed the difficulties in detail, identified the risk points, formulated safety guarantee measures, and arranged for the strongest "military forces" to rush for work. At this time, Ship East could not provide detailed drawings. The second assembly department and the design department worked together to formulate the construction process with reference to the Hudong Zhonghua 13500TEU container ship drawing. The strength of the rudder system's temporary fixation scheme was checked many times, and all the items before construction were fully completed Ready to work.

In the evening of March 23, after the China Shipping Mars arrived at Changxing Pier No. 0, the technicians of the second assembly boarded the ship to check the situation on the ship. That night, the rudder blade scaffolding and the steering gear cabin ring welding were started. During the maintenance process, due to the severe wear of the rudder bearing cover, it was impossible to install it, and Dongding Company participated in the battle overnight to assist in plane processing. It is difficult to remove the wear ring and the bolt connecting the wear ring. The assembly of two specific small tools solves this problem. The various departments of Hudong Zhonghua worked together and worked hard day and night to complete all the restoration work on March 29 with high quality. On March 30, the "CNOOC Mars" left the company's base zero and put into operation.
