SHANGHAI, July 31 (Xinhua) -- Yangshan Port in east China's Shanghai Municipality has become the country's first port to offer bunkering services for liquefied natural gas (LNG), green methanol, biofuels and ultra-low sulfur fuel oil, according to local authorities.

Recently, bunkering vessel Qi Hong 9 carried out a bunkering operation at the port, supplying 875 tonnes of domestic ultra-low sulfur fuel oil to the COSCO PRIDE ship.

It was the first ship-to-ship bunkering operation involving Chinese ultra-low sulfur fuel oil for an internationally navigating vessel in China, the port said.

According to the International Maritime Organization (IMO), the sulfur content limit for fuel oil used by ships navigating in certain international waters was reduced from 0.5 percent to 0.1 percent from May 1, 2025.

The domestic ultra-low sulfur fuel oil supplied at Yangshan Port was produced by PetroChina Huabei Petrochemical Company.
