It is reported that the marine power battery fire monitoring system jointly developed by both parties adopts low-power wide area network (LoRa) technology, simplifies the installation process, and also has mobile and onshore control functions. Compared with traditional ship cabin fire safety monitoring systems that use wired monitoring methods, this system using wireless sensor networks can effectively avoid problems such as high cost, complex wiring, poor scalability, and difficulty in equipment maintenance in the later stage of wired monitoring systems, thus gaining wider application.
In addition, the system also integrates artificial intelligence (AI) technology to determine whether a fire is occurring by analyzing and measuring temperature, humidity, and thermal imaging camera images, which can cut off the possibility of false alarms from fire perception sensors at the source.
According to the agreement, HD Hyundai Oita will be responsible for developing safety and design technologies for preventing battery fires on ships under construction, while Hancom Ubi Micro will be responsible for developing five composite gas (oxygen, carbon dioxide, carbon monoxide, methane, hydrogen sulfide) detection devices for ship battery rooms, as well as fire and temperature monitoring systems, equipment remote control, and comprehensive control systems.
It is reported that both parties plan to develop a new marine power battery fire monitoring system by the end of October this year, and install it on the 24000 ton LNG power roll on/roll off ship (RO-RO) built by HD Hyundai Oita for shipowners in the Oceania region for testing to verify its safety and reliability.
The construction contract for the 24000 ton LNG powered roll on/roll off ship was signed in February 2022, with a total length of 234 meters, a width of 35 meters, and a depth of 33.3 meters. It is a twin skeg ship equipped with two LNG dual fuel engines, which disperses thrust through two propellers and has a higher fuel efficiency than a single stern ship. In addition, this type of ship is also equipped with two sets of 680 kWh batteries used by ships entering and exiting the port, which can reduce harmful gas emissions along the coast.
Previously, HD Hyundai Oita has continuously built and delivered electric propulsion ships such as the "Ulsan Teahwa" 2700 ton intelligent electric propulsion passenger ship and the "Manxman" 25000 ton diesel electric hybrid roll on/roll off passenger ship (RO-PAX) in 2022 and 2023, accumulating design technology for battery rooms to prevent fire accidents such as temperature and humidity sensing and control, fire monitoring and alarm, and fire extinguishing equipment startup.
According to industry insiders in South Korea, if the wireless marine power battery fire monitoring technology is commercialized, the 24000 ton LNG power roll on/roll off ship carrying power batteries under construction can quickly respond to fires through real-time monitoring, and is expected to minimize accident losses.
HD Hyundai's executive Li Changjun and Hancom Ubi Micro representative Jin Minjun attended the signing ceremony on that day. Li Changjun said, "The company plans to ensure cutting-edge technology for preventing battery fire accidents, protect the safety of electric and hybrid propulsion ships, and accelerate the development of differentiated technologies."
