New process for converting 121,000 tons of whole ship shells in Jiangdong Shipyard

The 12#1000TEU ship is a PSPC ice zone enhanced container ship built by the Changhang Heavy Industry Jiangdong Shipyard for the German Buss Ship Fund Co., Ltd. At present, the 1# slipway of the headquarters of Jiangdong Shipyard has successfully completed the whole ship shell ice zone painting project. This is the first ship that Jiangdong Shipyard implemented in the completion of the ship's finished paint on the berth, marking the new shipbuilding transformation model. Progress.

The modern shipbuilding mode is an advanced shipbuilding method, which plays a decisive role in improving the management level of shipbuilding production and improving production efficiency. In order to effectively shorten the shipbuilding period, effectively improve production efficiency and reduce shipbuilding costs, the shipyard actively researched and implemented new shipbuilding technology, changed the traditional shipbuilding process according to the process route, which was divided into professional work by technical process, and then hull after repainting. The mode is converted into the code according to the design. The intermediate products divided by region are produced by mixed work, composite work, synchronous operation of the shell coating, separation and integration, and complete pre-assembly in the hull section. For the basic units, complete the modern shipbuilding mode of armoring and painting work as much as possible before the ship is launched.

There are many factors affecting the painting of the 1000TEU ship ice zone. The degree of pre-installation determines the time of paint construction in the ice zone. According to the actual situation of the previous ships, the construction is carried out at the docking, but the 12#1000TEU ship, Jiangdong Under the unified arrangement of the engineering department, the shipyard decoration branch changed the method of implementing the outer shell paint in the underwater area and transformed it into the construction of the ship platform.

Since April, in order to prevent the damage of the outer shell ice area after the 12#1000TEU ship is completed, the decorating plant has thought about the arrangement in advance, and thoroughly flushed the whole ship joint, the ice zone weld seam and the outer shell bow load. In order to ensure that the repair and polishing can pass the ship owner and IP inspection, it is ensured that the initial work of the first shed, welding, water mark, etc. affecting the ice zone with 3.5~8.6 meters and above 8.6 meters is fully completed.

During the May Day, in order to promote the smooth construction of the 12#1000 box ship's entire ship shell paint. Before the construction, seriously carry out the 12# ship shell ice area paint production special meeting, arrange the production plan in detail, and communicate with the ship owner and service provider to reach a consensus, and draw up specific construction procedures. The decorating branch leaders attach great importance to the satisfaction. Requirements, actively deploying diesel, diesel, electric air compressors, sand, etc. in one step, arrange clamps, electricians on duty, two construction teams at the same time construction, and carefully prepare for sand washing.

In order to complete the shell paint project before the rain on May 8, considering the short time and heavy task, the branch arranges two comrades Fang Hui and Zhao Suyong to fight at the forefront of production and arrange for staff to work 24 hours a day. No complaints, sticking to the production position, working diligently, working overtime, on the evening of May 2nd and 3rd, the first part of the night was washed in the sand. At 15:00 on the 4th, the first part of the ice was painted between 3.5 meters and 8.6 meters. To be done, as of 15:00 on May 7th, the 12#1000 box full-ship shell ice area paint project was fully completed. This huge project took only 5 days to complete.

The implementation of the process plan not only takes an important step for Jiangdong Shipyard to implement modern shipbuilding, but also improves efficiency, shortens cycle and reduces costs. Moreover, the principle of modern shipbuilding "waterwork on the ground" has been implemented, which has effectively reduced the safety risks and laid the foundation for the company to adapt to the modern shipbuilding mode as soon as possible, the ship launching and delivery on time.
