"This catamaran pure electric propulsion sightseeing boat was invested and built by Kunming Xiang Kun Waterway Co., Ltd., with a total design length of 35.8 meters, a boat width of 8 meters, a depth of 2.3 meters and a * * 3-layer structure. The propulsion system consists of two 75 kW motors, and the battery is lithium ferrous phosphate 150Ah certified by China Classification Society. The rated capacity of the battery system is 1200Ah, and the total storage capacity reaches 737 kWh. The relevant person in charge of the Kunming Local Maritime Safety Administration said that the ship battery system adopts a mature battery management system, which can monitor the working state and temperature change of each battery in real time, and realize the safety redundancy design by connecting four batteries in parallel in two cabins. " In the future operation, even if the battery in one compartment fails, the other battery compartments can ensure the safe navigation of the ship 1 hour. "
It is understood that by replacing the current LPG fuel power system with a pure electric propulsion system, the ship has eliminated the emission of tail gas and waste liquid, realized zero pollution and zero emission of waste water, waste gas and solid waste, greatly reduced noise and vibration, improved ride comfort and environmental protection, and met the requirements of safe, convenient, efficient, green and economical transportation system construction.
"This ship is the first catamaran pure electric propulsion large passenger ship in Yunnan Province, which will play an important role in promoting the development of Kunming pure electric large passenger ship. Replacing the existing liquefied petroleum gas passenger ship with pure electric propulsion is an important measure for Kunming Local Maritime Safety Administration to promote the upgrading of ship power system, improve the anti-pollution ability of ships and ports in Dianchi Lake waters, and help the three major battles of "blue sky", "clear water" and "pure land". " The person in charge said that the launch test is expected to be completed in August, and the test can be carried out after the test is completed in June 5438+ 10. It will mainly sail in Caohai waters of Dianchi Lake for tourists to visit. "After completion, the ship will not only operate during the day, but also sail at night. This is also one of the important platforms for Kunming Local Maritime Safety Administration to build a night economy in the water transport industry by restoring the night navigation in Dianchi Lake."
According to relevant data, there was night sailing in Caohai Lake in Dianchi Lake as early as 1986, but due to the problems of navigation channel, ship power and night sailing safety, the night sailing activities were once stopped. In recent years, the voice of governments at all levels is getting louder and louder, and the policy support for developing night economy is getting stronger and stronger. At the beginning of last year, the main leaders of Kunming Municipal Party Committee and Municipal Government respectively made important instructions on developing night economy. It is in line with the needs of local economic development to start night sailing in Caohai, Dianchi Lake, Kunming. After the resumption of night flights, more tourists will be attracted to stay in Kunming for sightseeing, which will also boost the consumption market of accommodation, catering and tourism products.
It is understood that from 2065438 to September 2009, Yunnan Water Transport Planning and Design Institute signed a tripartite cooperation agreement with Kunming Water Transport Industry Association, as well as three water transport enterprises, namely Kunming Dianchi Tourism Passenger Transport Co., Ltd., Kunming Xiang Kun Water Transport Company and Kunming Bangye Water Passenger Transport Co., Ltd., for the consultation service of "Kunming Dianchi Caohai Night Flight Recovery Assessment Report", which marked the official start of Kunming Dianchi Caohai Night Flight Recovery. On the basis of preliminary investigation, the Assessment Report on Night Navigation Recovery of Caohai Lake in Dianchi Lake, Kunming analyzes the current shipping situation of Caohai Lake, and puts forward constructive suggestions on navigation facilities and safety, ship type and safety and environmental protection requirements, dock facilities construction and ship berthing safety, and landscape of night lighting facilities, which will serve as an important basis for industry management departments to make administrative licenses.
