The gangway to a ship that is under construction collapsed at around 9:30 a.m. at the Ozai shipyard of Minaminippon Shipbuilding Co., sending workers falling to the ground or into the sea, local fire department and police officials said.
The gangway collapsed shortly after it was installed using a crane, Kyodo News quoted the officials as saying. Some of the injured were taken to nearby hospitals, while those who sustained slight injuries were treated at a tent set up near the accident site.
According to Minaminippon Shipbuilding, the shipyard was completed in May last year as the company's third plant for manufacturing large vessels.
