On June 24, a naming and delivery ceremony was held for the scientific research ship “JI DI” at Guangzhou Shipyard International Company Limited, which was surveyed by China Classification Society (CCS), and Zhou Liwei, Deputy General Manager of CCS Guangzhou Branch, was invited to attend the ceremony.

The scientific research vessel “JI DI”, 89.95m long, 17.8m wide, 8.2m deep, having a design speed of 15 knots and an endurance of 14,000 nautical miles, can meet the navigation needs of unlimited navigation areas, with a single supply to guarantee the living of 60 people at sea for 80 days.

This vessel is equipped with an ice-breaking bow and featured additional marks including “Ice Breaker”, “PC 6”, “ACC-POLAR (-30 ℃)”, “Underwater Noise 2”, etc.

As a new generation of polar scientific research vessel independently designed and constructed by China, this vessel adopts a full-rotary electric propulsion system and is equipped with a channel-type lateral thrust, dynamic positioning system, and anti-rolling system. Featuring underwater radiation noise that meets the requirements of ‘Underwater Noise 2’, it is also the first ship that was awarded the additional mark of “Polar Service Temperature to -30 ℃” by CCS. With its bow designed to break through 1.0 meter of the current year’s ice, and designed service temperature of as low as -30 ℃, it can cooperate with various marine survey equipment to undertake comprehensive observation and investigation tasks of sea ice, three-dimensional water bodies, geophysics, atmosphere, and other marine environment. It also has ice rescue and summer polar sea scientific exploration capabilities while being used for monitoring and investigating the marine environment in ice areas.

During the construction process of the “JI DI” vessel, the Nansha Inspection Department of CCS Guangzhou Branch has closely cooperated with the shipowner and the shipyard. According to the requirements of the “Guidelines for New Shipbuilding Project Management”, before starting construction, it has actively assisted the shipyard in sorting out the products that need to meet the low-temperature requirements based on the characteristics of the vessel and in combination with the “Guidelines for Polar Ship”, and established a production plan oriented tracking table to track the certification of 29 products that need to meet the low-temperature requirements.

During the construction process, CCS has actively cooperated with the production and successfully guaranteed the key nodes such as alignment & observation, mooring test, inclination test, navigation test, etc. During this period, CCS has also collaborated with the shipyard and the supplier to solve key technical problems such as propeller noise to ensure successful delivery of the vessel.

The launch of the “JI DI” vessel will further enhance China’s capability to prevent and reduce marine disasters such as sea ice, enrich China’s ice region research system, facilitate the comprehensive survey and investigation of polar oceans, sea ice, atmosphere, etc., and advance China’s ice region research towards serialization and diversification.
