Stena Bulk introduced the final ship in a 13-series of chemical and product tankers at Guangzhou Shipbuilding International in China with a naming ceremony that started with traditional Chinese dancing and music.

Then Jean Mulholland, acting as godmother, swung a bottle of champagne against the 49,400-dwt Stena Impero's bow.

The naming capped an order that represents a SEK 4bn ($406m) investment for the Stena group subsidiary.
