For shipbuilding executive Chen Yong, the shiprepair business has not shed its reputation as a "3D" business — dangerous, difficult and dirty.

But speaking to invited representatives of his European and Asian competitors, the president of Zhoushan IMC-Yongyue Shipyard and Engineering Co (IMC-YY) said he believes it is time for that to change.

"Only the shiprepair industry has remained in the past, and it is time for our industry to take responsibility," Chen said.
