Taiwan is stepping up efforts to recover more than 1,000 empty containers that are now feared to have been lost from a box ship which listed then sank outside the port of Kaohsiung.
Initially, around 600 containers were estimated to have been lost from the Angel, but reports suggest the figure could now be higher.
The approach of Typhoon Docksui has added to the urgency of the operation.
The typhoon is likely to be the strongest in the region this year and is set to batter Taiwan with strong winds and rain as it passes before landing on China at the end of the week.
According to local paper Focus Taiwan, quoting figures from the Taiwan International Ports Co, 573 containers have been tracked down, of which 206 have been retrieved, 120 have washed ashore, 247 have sunk.
The containers have drifted to the Linyuan District in Kaohsiung and Donggang Township.
The worsening weather could also affect attempts to refloat the wreck of the Angel which, although sunk, remains partially above the waterline.
The vessel has around 393.4 metric tonnes of low-sulphur fuel oil on board and 91 tonnes of diesel. Oil pollution prevention measures have been put in place around the vessel.
The vessel went into a list after taking on water after apparent structural problems.
The empty containers suggest that the vessel has not been trading for some time. The Indian Register of Shipping withdrew classification of the Palau-registered ship in May this year.
