The industrial city, which is one of the world's busiest ports, is under a harsh lockdown with millions of people banned from leaving their homes and relying on the government to deliver food.
Images taken from the MarineTraffic website, which tracks the live positions of a range of vessels in international waters, show huge queues around the Port of Shanghai with thousands of ships and vessels trying to manoeuvre.
Experts have raised concerns about the impact of the Shanghai lockdown on global supply chains, particularly regarding delays and increased costs.
The Port of Shanghai continues to operate normally under a 'closed loop' system where it is sealed off from the city, but there have been difficulties with trucks entering and exiting, leading to delays.
Despite the "normal" operations, vessel loading has decreased 20% to 30%, and several carriers, including Maersk, ONE and 2M are currently not calling on the stop, the Port of Shanghai said.
A senior Chinese official said the Shanghai port is making "all-out" efforts to ensure stable and smooth operation in order to stave off the impact brought by COVID's resurgence.
