The Star Cruises' ship 'Superstar Gemini' was towed in to the yard for emergency repairs to fouled propellors. En route from Shanghai to Jeju Island the Superstar Gemeni's port side propellor shut down after becoming entangled with fishing nets and ropes, and while in the CJK anchorage the remaining starboard side unit shut down as well, leaving the cruise ship without means of propulsion. CIC Changxin shipyard quickly arranged five tugs to bring 'Superstar Gemini' into its JiuhuaShan floating dock where it was found that the propellers were entangled with fishing nets and ropes. The shipyard immediately organized inspection and repair of the ship, and after working 20 hours, the propellors were cleared and the vessel smoothly un-docked, to head for the Shanghai cruise terminal.
