Taizhou is known as the “domestic small shipbuilding baseâ€, and Songmen Town in its jurisdiction is a gathering place for private shipbuilding. In recent years, due to the continuous reduction of export orders, the construction of new ships has been shrinking. The shipyards in Taizhou are “endangered†and “machines†have begun to take ship repairs as a new business growth point.
Looking for business opportunities in the market blank
“In the process of actively guiding the major shipyards to find new ways to boost the efficiency of the shipbuilding industry, we found that there are hundreds of ships within 10,000 tons within Taizhou, and there is no corresponding maintenance base in the local area.†Deputy Director of Taizhou Port and Shipping Administration Zheng Xianmei said, "To fill this gap in the market will definitely bring business opportunities to shipbuilding enterprises, and will also help promote the transformation and upgrading of the shipbuilding industry."
However, due to the lack of a dock, the traditional cable pull can only pull a small vessel of 50 meters in size. "This has limited our maintenance of the ship repair business of over 10,000 tons of 10,000 tons," said Chen Cunyu, head of Zhejiang Hexing Shipyard.
Make a move and move. Since last year, under the active advocacy of industry authorities, engineers led by Chen Cunyu and teamed up with five shipyards have begun to develop a new type of hydraulic flatbed that can push ships from the sea directly to shore.
Today, the deep-dive heavy-duty hydraulic flatbeds they developed have been declared national patents and promoted to the public. This means that from the landing of ships with traditional steel cables to the design of dedicated deep submersible heavy-duty hydraulic flatbed trucks, the shipyard guarantees production safety through technological innovation and achieves energy saving and environmental protection.
Technological innovation has achieved results
It is understood that the deep-submersible heavy-duty hydraulic flatbed has a maximum carrying capacity of 3,000 tons, which can meet the needs of various ships with a length of less than 130M. The equipment fully utilizes the inertial force to convert kinetic energy into electric energy, so that each ship can save 200 watts of electricity by entering the factory, saving 120,000 kWh per year, which can fill the current domestic ship of 2000-10000 tons without the need to enter the dock for effective repair. Market gap.
At the same time, the equipment can save about 80% compared with the docking time, and the working efficiency is increased by about 4 times, which makes the ship into the factory safer and more stable, energy-saving and environmentally friendly, convenient and fast, and greatly reduces the safety hazard. In order to demonstrate the actual application of the equipment, in the field when a lightly pressed switch, a deep submersible heavy-duty hydraulic flatbed dive, 50 minutes later, a 5,000-ton ship was steadily pulled ashore, placed Drop the pier at the designated location.
It is reported that from 2012 to now, the shipyard has arranged 8 engineers and more than 4 million yuan to specifically design and design the hydraulic flatbed equipment. In April this year, the shipyard has applied for 5 patents to the National Patent Office, including 4 utility model patents and 1 invention patent. The deep submersible heavy-duty hydraulic flatbed adopts integrated control technology of machine, electricity and liquid. The six automatic variable pumps control the dive, upshift, lift, descent and brake of the flatbed respectively, so as to realize the movement of the ship from the water. The purpose of carrying out renovation and maintenance on land has solved the safety problem of the ship entering the factory.
At present, there are already shipyards in Fujian and Guangdong to inspect the equipment in Taizhou, and clearly expressed their purchasing intentions.
