English: In recent months, the Port of Singapore, one of the busiest ports in the world, has been experiencing congestion in its operations. Data from S&P Global Platts show that an average day in January 2021 saw about 46 vessels anchored at the Port of Singapore, a 59% increase compared to January 2020. According to media reports, the exceptional situation that has caused an increase in waiting time for ships docked outside of numerous global ports has come about due to a confluence of factors, including an unprecedented increase in cargo demand, congestion at all nodes of the global supply chain due to renewed COVID-19 lockdowns, a shortage of available containers, and the reliability of shipping sailing schedules falling to a 10-year low. This image, acquired on 20 November 2020 by one of the Copernicus Sentinel-2 satellites, shows more than 85 cargo vessels and tankers awaiting entry to the Port of Singapore. The combined use of radar and optical data captured by the Copernicus satellites provides useful information that can be used for maritime surveillance worldwide.
