第100个中国自主研发的围护系统B型舱在沪完工

Core Viewpoint - Jiangnan Shipyard has achieved a significant milestone by completing its 100th B-type tank, marking the transition from engineering validation to stable mass production of its independently developed B-type tank technology [1] Group 1: B-type Tank Development - The B-type tank is a domestically designed and developed containment system that breaks the foreign monopoly on low-temperature containment systems [1] - The B-type tank is primarily used in Very Large Ethane Carriers (VLECs) and offers advantages such as no loading restrictions, no liquid sloshing risk, high space utilization, and long service life compared to traditional A-type, C-type, and membrane tanks [1] - Jiangnan Shipyard officially started the independent research and development of the B-type tank in 2014, with the first B-type tank completed in 2021 and applied to a VLEC, marking a breakthrough in China's high-end liquid cargo tank core equipment field [1] Group 2: Production Efficiency - The construction cycle for a single B-type tank has been reduced from an initial 140 days to 88 days, a decrease of 37.1% [1] - The monthly delivery capacity has increased from 0.64 tanks per month to 6 tanks per month, resulting in an 840% improvement in production efficiency [1] Group 3: Future Plans - Jiangnan Shipyard is focused on breaking the long-standing technological monopoly in the LNG (Liquefied Natural Gas) containment system field and is working towards the complete independent development of B-type tanks for large LNG carriers [2]
