China has achieved a milestone in shipbuilding following the delivery of the world's largest shuttle oil tanker to Shanghai North Sea Shipping. The NS Pioneer, a 155,000-tonne dynamic positioning shuttle tanker, built by Dalian Shipbuilding Industry Company, is China's first Suez max vessel of its type built by a Chinese shipyard for a Chinese customer. When fully fueled, the 279-meter-long, 48-meter-wide vessel can sail up to 22,000 nautical miles, about the distance of two round trips from Shanghai to Dubai in the United Arab Emirates.
