In Asian ports like Hong Kong and Singapore it is usual to see a cluster of small coastal tankers anchored off to one side. Unlike the big crude carriers, these little ships carry refined products throughout the area to supply the small ports and harbors. Relatively unheralded they are often launched and go into service without all the fan fare that accompanies their very large cousins. Ocean Leader Shipbuilding Co. Ltd, located in the Pearl River delta of Guangdong Province southern China, specializes in building these coastal tankers.
