  • The number of AIS signals from vessels in Chinese waters plummeted by 85% in less than a month.

  • Shipping companies use the data for a variety of purposes, such as planning routes.

  • Data loss can exacerbate the current supply chain crisis.

Vessels in Chinese waters have disappeared from the tracking systems used by the maritime industry. This is a development that can make the world worse. Supply chain crisis.

Automatic identification systems (AIS) rely on ships to send data to stations via stations and satellites along the coastline, but the signals they receive have plummeted in the last few weeks.

According to data from market intelligence and rating provider Vessels Value, signal numbers in China’s waters plummeted 85% in less than a month, from more than 100,000 a day on October 28 to 15,000 a day on November 17. It has decreased more than the number.

Shipping companies use the data for a variety of purposes, including route planning, logistics operations, and congestion analysis.

Charlotte Cook, head trade analyst at VesselsValue, said the decline in this data is one of the world’s major trading nations, as these signals usually provide maximum data coverage and insights on transport at ports in China. It states that it can have a significant impact on the visibility of an ocean supply chain across China. Statement to insiders.

“The increasing availability and volume of AIS data in recent years has made the industry widely dependent, allowing shipping companies to anticipate vessel movements in advance, track seasonal trends and improve port efficiency. “It has become,” Cook said.

“Ultimately, a significant reduction in the number of vessels signaling in China will reduce the ability to accurately monitor vessel activity, which could have a knock-on effect on the already squeezed global supply chain. There is, “she added.

“If this continues, it will have a significant impact on global visibility, especially during the busy Christmas period when the supply chain is already facing major problems around the world,” said AIS Network Team Leader for Ship Tracking and Maritime.
