From July 14 to 17, 2021, the 1000T shallow water salvage engineering ship "Defu 1200" built by Yantai Salvage Bureau adopted the ship airbag upper and lower water technology, rolled the ship into a semi-submersible ship, and successfully floated in the waters of Zhifu Island, Yantai into the water.

The "Defu 1200" shallow water salvage engineering ship launched this time has a total length of 106 meters, a molded width of 42 meters, a molded depth of 7.5 meters, a maximum sinking depth of 12 meters, a maximum lifting capacity of 1,200 tons, and a launching weight of more than 9,700 tons. . Shandong Changlin Marine Airbag and Ball Leaning Technology Research Center independently undertook the design and construction of this type of ship using airbags to move the ship to a semi-submersible ship. In order to ensure the safety of launching the ship, the designers of Changlin Technology Research Center considered that the wide width of this type of ship, the keel pier with a width of nearly five meters in the middle of the deck of the semi-submersible ship and the channels of the pontoons on both sides of the semi-submersible ship were "narrow". ", the small deck operation area and other factors brought difficulties to the launch of the airbag, strictly starting from the process, formulated a detailed process technology plan, and cooperated closely with the technical staff of the shipbuilding center of Yantai Salvage Bureau to fully carry out the airbag ro-ro launch plan. demonstration and passed expert review. Careful planning and relatively adequate preparations have been made for the launching project.

At 6:18 a.m. on July 14th, following the order to launch, the ship "rides" 64 high-capacity airbags produced by Jinan Changlin Airbag Container Factory, and is slowly launched on the berth under the traction of two winches. The operator strictly implements the process plan, adjusts the working pressure and working height of the airbag in a timely manner, and carefully operates the whole process. After three and a half hours of slow "crawling", the giant weighing nearly 10,000 tons was finally safely and smoothly moved by roll-on-roll to the predetermined position on the semi-submersible ship. The displacement is more than 100 meters, the center deviation is less than 100mm, and the accuracy of moving the ship is first-class. After a series of operation preparations such as sitting on the pier, vacuuming the airbag, and fixing, the ship was successfully floated and launched in the waters of Zhifu Island on the 17th.

Ship airbag launching is an innovative technology with my country's independent intellectual property rights. The successful launch of the ship has filled the blank of my country's large-scale shallow water salvage engineering ship using ship airbag launching and launching technology, and roll-on shifting to semi-submersible ships for launching. Compared with the traditional hydraulic boat moving method, it has many advantages such as safety, labor saving, environmental protection, etc., and is more scalable. The implementation of this project has laid a good foundation for further research on airbag launching technology for large special engineering ships.

Announcement: Changlin Airbag does not participate in the brand ranking network's "China Marine Airbag Top Ten Brand Selection" voting statement

At the beginning of October 2019, the "Changlin" brand of Jinan Changlin Airbag Container Factory Co., Ltd. was unknowingly involved in the online voting of the "2019 Top Ten Marine Airbag Brand Selection" initiated by the "Brand Ranking Network" Activity. At the beginning of the event, the "Changlin" brand was popular among customers based on the industry image established by high-quality products and services for more than 20 years and the influence of two international standards, a number of national standards and industry standards. With the attention and support of friends from all walks of life, the ranking has always been among the best, which fully proves the high popularity and influence of the "Changlin" brand. Here, Changlin people express their gratitude to all the customers and friends from all walks of life who support the "Changlin" brand! However, recently, our company personnel have been receiving calls about providing ticket swiping services. After investigation, we found that there are indeed many commercial transactions and hidden rules similar to online voting, and the so-called national industry brand activities launched have not been approved by the Ministry of Industry and Information Technology or anywhere. Approved or authorized by government agencies and organizations, the selection results do not have the credibility, authority, fairness and legitimacy of the brand ranking. Sina Finance, Beijing Times and many other media have no qualifications for the selection agency. The process of the activity is full of loopholes, and the results of the selection are mixed. They have reported the illegal behavior of accumulating money and constantly damaging the brand image. In this regard, the company has made a careful study and decided to solemnly declare that Changlin Airbag will not participate in the so-called "2019 Top Ten Marine Airbag Brand Selection" online voting organized by the website. Jinan Changlin Airbag Container Factory Co., Ltd., as a leading enterprise specializing in the research and development of marine upper and lower water airbags, marine inflatable rubber balls (inflatable fenders) and water technology research for nearly 30 years, is constantly conducting product research and development, water technology research At the same time, it always puts improving product quality and providing high-quality services in the first place. Its products have been widely used in various ships such as large bulk carriers, self-propelled semi-submersible ships, jack-up offshore oil drilling platforms, and offshore wind power installation ships. The upper and lower water operations and berthing. The two airbag international standards carry the wisdom of Changlin people, so that the products are exported to South Asia and European and American markets. "Changlin" brand has been recognized and highly appraised by customers. At the same time, the development of Changlin airbags is inseparable from the care and support of our customers and friends from all walks of life. Changlin people will also live up to expectations, lead the industry to continue to work hard, and strive to provide customers with better products and technical services.
