Design edit
Ji Di is 89 metres (292 ft) long overall and has a beam of 17.8 metres (58 ft) and draft of 5.9 metres (19 ft). The 5,600-tonne (5,500-long-ton) vessel has accommodation for 60 persons, operational range of 14,000 nautical miles (26,000 km; 16,000 mi), and can remain at sea for 80 days.[3][4]
Ji Di has a diesel-electric propulsion system with four main diesel generators and two 3.2-megawatt (4,300 hp) ABB Azipod azimuth thrusters.[1][5] The ship's speed in open water is 14 knots (26 km/h; 16 mph) and it can break 1-metre (3.3 ft) level ice at a speed of 1.5 to 2 knots (2.8 to 3.7 km/h; 1.7 to 2.3 mph).[6][7]
Ji Di is built to Polar Class 6,[1] an ice class intended for summer and autumn operation in medium first-year ice which may contain small inclusions of old sea ice that has survived at least one melting season without melting completely.[8]
History edit
The ship's construction was awarded to Guangzhou Shipyard International, a subsidiary of the China State Shipbuilding Corporation, in March 2022 and the construction began shortly afterwards.[1] It was floated out on 29 December 2023.[3][4]
Ji Di, Chinese for "polar", is scheduled to enter service with the State Oceanic Administration North Sea Branch during the second half of 2024.[1]
