China is not just building massive oil tankers, it is also developing ships to make them more efficient and fuel-saving.
The 114,000-ton Albert Park recently completed sea trials in China equipped with three giant rigid wing sails designed to assist propulsion using wind. Each sail stands about 37.5 meters tall, and under ideal conditions, the system can reduce fuel consumption by up to 14.5 tonnes per day.
More importantly, this technology is no longer just an experiment: it is now entering serial commercial production at Chinese shipyards.
