Development path

1993 Successfully developed the first generation of marine airbags with independent intellectual property rights.
the
In 1994, the first domestic thousand-ton ship was launched using Changlin airbags, which was rated as one of the top ten scientific and technological achievements in the shipbuilding industry that year.
the
In 1995, Hubei Xishui Shipyard used Changlin airbags to launch 8,000DWT deck barges, and the launching weight reached 1,200 tons, breaking through the 1,000-ton mark for the first time.
the
In 1996, our company drafted my country's first marine airbag standard CB/T3795 "Airbags for Rising and Launching Ships" and was officially promulgated; this is also the first airbag standard promulgated and used in the world.
The air bag upper discharge for ships is a promising new technology. It overcomes the disadvantages of small and medium-sized shipyards in the past that the ship repairing and building capabilities were limited by fixed launching slides, and has developed into a flexible and flexible launching technology that saves labor and effort. , saving time, saving investment, safe and reliable, and remarkable economic benefits.
the
In 1997, the "Changlin brand" floating inflatable rubber ball (fender) was successfully developed; it filled the domestic gap in this industry and obtained the national invention patent.
the
In 1998, the inflatable rubber ball (guard) passed the provincial appraisal.
the
In 1999, our company undertook the launching project of the "Haijian No. 3002" engineering ship of Lushun Shipyard, creating a precedent for the application of airbags for lateral launching of engineering ships.
the
In 2000, the Navy Shanghai Base ordered the first "Changlin Brand" floating inflatable ball to welcome the Australian Navy fleet to visit China.
the
In 2001, my country drafted the first ball-based standard, promulgated and implemented it. Inflatable rubber fender) is one of the most advanced ship anti-collision products in the world today. It uses compressed air as a buffer medium to absorb the collision energy when the ship is near. Compared with the general rubber fender, it has better absorption. It has the characteristics of large energy, small counter force and easy installation.
the
In 2002, the first 10,000-ton oil tanker "Zhouhaiyou 28" was successfully launched in Huangyan Jixiang Dock Company, Taizhou City, Zhejiang Province, using Changlin airbags, which marked a new breakthrough in the technology of airbag launching and launching, and created a new era of airbag launching for 10,000-ton ships. new stage.
the
In 2003, "high bearing capacity multi-layer kneading airbag" passed the provincial appraisal and won the third prize of Shandong Science and Technology Progress Award.
the
In 2004, China Road and Bridge Corporation successfully used Changlin airbags to transport a single reinforced concrete caisson weighing 2,320 tons in Panyu, Guangzhou.
the
In 2005, the 8,100 cubic meter trailing suction dredger of Taizhou Huangyan Jixiang Dock Co., Ltd. in Zhejiang Province was successfully launched using Changlin airbags, and the launching weight exceeded 5,000 tons for the first time.
the
In 2006, our company won the high-tech enterprise of Shandong Science and Technology Department
the
In 2007, the special ramp for launching low-slope double-angled airbags designed by our company was completed and put into production in Yangzhou Guoyu Shipbuilding Co., Ltd. The first 45,000-ton "Guoyu Haipi No. 1" manufactured by it was successfully launched using Changlin airbags, setting a record for the launch weight of the airbags breaking 9,000 tons.
the
In 2008, the 55,000-ton Panamax bulk carrier "VICTORIA" was successfully launched at Zhejiang Sanmen Jiantiao Shipyard using Changlin airbags. The ship was 190 meters long, 3,226 meters wide, and 18 meters deep, with a weight of 12,000 tons when launched. It marks that the weight of the airbag launched into the water has broken through the 10,000-ton mark.
