Currently, the number of Chinese VOSs is showing a decreasing trend, which has decreased from more than one hundred ships in the past to the current number of thirty something ships. Moreover, the observation capabilities have many existing problems, such as relatively outdated observation measures, simple observation parameters, and lack of observation data. Fundamentally speaking, the operation mechanism of VOSs lacks effective systematic assurance and protection. Consequently, these VOSs are unable to have sufficient operational capabilities and cannot effectively fulfill their international obligations.展开更多

Ltd in February, 2006, The ship will be a new member of the Yuanwang ocean-going in strumentation ship fleet. The new ship can withstand Force 12 ocean wind and sail on the sea between 60° N latitude and 60 S latitude.展开更多

To guarantee the installation space and environmental requirements of the observation equipment, the drop keel system was proposed for the first time for ocean-graphic ships at China, to avoid the traditional ＂rudder-shaft＂ type fin keel＇s disadvantage. The research study will examine the operational mechanism and functions of the drop keel system, the operating conditions of the fin keel to determine the driver method and its arrangement, and the locking method of the fin keel underwater. The research wilI also provide some general designs for analyzing the best plan for the drop keel system.展开更多
