Baihetan, China’s first 2,000-tonne offshore wind farm installation vessel, was launched on Wednesday in Guangzhou, south China’s Guangdong Province.

Built by China Three Gorges Corporation, the 126-meter-long, 50-meter-wide vessel has a full load displacement of 37,000 tonnes and integrates functions such as transport, self-elevation, self-propulsion, lifting and dynamic positioning.

With a maximum variable load of 6,500 tonnes and a deck area of 4,200 square meters, the vessel can be used for the installation of offshore wind turbines of up to 15 megawatts.

The vessel is able to lift goods as heavy as 2,000 tonnes and work underwater as deep as 70 meters, which greatly enhances the country’s construction and installation capacity in offshore deep-water and off-lying sea areas.

The construction of the vessel started in July 2021. It is expected to be delivered and put into operation within this year, and will be mainly operated in Guangdong and Fujian provinces, according to the company.

China will launch a national campaign to better mobilize the science and technology sector to contribute to the country’s rural revitalization drive, according to a new set of guidelines.

Jointly issued by the China Association for Science and Technology and the National Rural Revitalization Administration, the guidelines specify a series of key tasks, including providing sci-tech training, lectures and industry-specific guidance to rural areas.

Sci-tech associations at all levels are called on to lead grassroots sci-tech workers to join in the work of rural revitalization.

The guidelines also require the relevant authorities to incorporate the construction of science popularization facilities into the overall layout of rural infrastructure, expand the service coverage of mobile science popularization facilities and build more sci-tech museums in rural secondary schools.

The Long March-7 Y4 rocket carrying the Tianzhou-3 blasted off at 3:10 p.m. (BJT) on September 20, 2021, from the Wenchang Spacecraft Launch Site in south China’s Hainan Province. It carried about six tonnes of goods, including food items and spacesuits, to the country’s under-construction space station. Six and a half hours later, the cargo spacecraft docked with core module Tianhe at 10:08 p.m. (BJT) on the same day.

The Tianzhou-3 separated from the space station core module Tianhe on July 17, 2022, after completing all assigned assembly tasks.

It is the third mission of China’s Tianzhou-class unmanned cargo spacecraft and the second resupply mission to the space station after Tianzhou-2.

Shanghai-based ZJ Biotech has received many urgent purchase orders from the World Health Organization (WHO) for its monkeypox virus test kit, and the company is now aiming to provide more support for accurate diagnosis and containment of the disease.

The WHO on Saturday activated its highest alert level for the growing monkeypox outbreak, declaring the virus a Public Health Emergency of International Concern.

The test kit developed by ZJ Biotech can accurately identify monkeypox virus by measuring the gene segment of the virus by specific fluorescence method.

“Currently the best detection method for many infectious pathogens across the world is the nucleic acid test, which has an accuracy rate of over 95 percent. It can reach more than 99 percent for some individual diseases,” said Shao Junbin, chairman of Shanghai ZJ Bio-Tech Co., Ltd.

The monkeypox virus test kit manufactured by the company has been sent to 41 countries and regions around the world. Of these, 24 emergency orders from the WHO were sent to 21 countries, covering Africa, Europe, Oceania and Southeast Asia.

At present, the company is in close contact with the WHO and health institutions in many countries around the world, aiming to provide support for accurate diagnosis and containment of the disease.
