China Huarong Energy has completed the sale of its shipyard assets to a bondholder.
The share transfer was completed this week, it said.
The Hong Kong-listed company agreed a deal with the unnamed bondholder last year for the former China Rongsheng Heavy Industries' "non-performing and debt-burdened" yard and engineering business.
Both parties released all debts on completion.
China Huarong will now focus on the energy exploration and production sector.
