Here is the story from the description
BACKGROUND A German-flagged container ship headed straight towards shore and briefly ran aground in Hong Kong on Sunday afternoon (April 6, 2014). The 192.5-meter-long Hansa Constitution was travelling along the busy East Lamma shipping channel when it suddenly veered off course. The Hong Kong Marine Department said the ship’s main engine broke down. People familiar with the shipping industry say the captain and Hong Kong maritime authorities decided to the best course of action was to beach the vessel to prevent it from colliding with other ships on the busy shipping channel. The crew dropped anchor at the last minute, making loud screeching noises, to slow Hansa Constitution as it headed straight towards the sea wall outside the University of Hong Kong sports grounds in Pok Fu Lam. The ship ground to a halt at around 15.22 local. It then slowly reversed, as Marine, police and fire services rushed to the site. It was eventually towed free. No one was injured.
The ship was travelling from Yokohama in Japan to Chiwan port in Shenzhen, China.
