On 30 October 2017, the UK registered container ship Ever Smart suffered a container stow collapse while on passage between Taipei, Taiwan, and Los Angeles, USA. The master had changed the ship’s passage plan to avoid severe weather caused by a developing depression east of Japan.
The ship continued in heavy seas; rolling and pitching heavily with frequent bow flare slamming. Once the weather had abated, the crew discovered that the container stacks on the aft-most bay had collapsed and toppled to port.
Of the 151 containers in the stow, 42 were lost overboard and 34 were damaged. Superficial damage was caused to the ship.
- the loss of the containers most likely occurred during a period of heavy pitching and hull vibration in the early morning of 30 October
- combination of factors resulted in a loss of integrity for the whole deck cargo bay; in particular, the containers were not stowed or secured in accordance with the cargo securing manual
- the container lashings might not have been secured correctly
Recommendations (2020/125, 2020/126 and 2020/127) have been made to Evergreen Marine Corp. (Taiwan) Ltd to improve standards of stowage plans produced ashore, knowledge of the dangers of bow flare slamming and lashing gear maintenance management.
