On July 15,2025, a grand ceremony was held at Dalian Dayaowan Container Terminal to mark the completion of Northeast Asia's green ship-to-ship methanol supply chain and the first bonded green methanol bunkering operation in Dalian. This milestone achievement marked  the port successfully conducting its inaugural green methanol bunkering service between vessels, while also securing the first bonded green methanol bunkering transaction in Northeast China. Zhang Hui, General Manager of China Classification Society (CCS) Dalian Branch, attended the ceremony.  

The 500-ton domestically produced bonded green methanol was delivered via a ship-to-ship bunkering operation conducted by the CCS-classed  methanol fuel tanker "Haigang Zhiyuan" to China's first methanol dual-fuel powered container vessel "Cosco Shipping Yangpu." This milestone fills the gap in bonded green methanol bunkering services for international vessels in Dalian, marking the full connectivity of Northeast Asia's green marine fuel supply chain. It signifies the establishment of a complete closed-loop system integrating integrating "Chinese ships" with "domestically developed green fuels" achieving a self-sufficient ecosystem for maritime energy solutions.

CCS actively participated in Dalian's efforts to accelerate the construction of the green ship fueling and transfer base. In 2024, CCS joined the Northeast Asia Green Ship Fuel Supply Chain Alliance. This operation fully leveraged CCS's technical advantages in green ship fueling, working closely with relevant parties including the Liaoning Maritime Safety Administration, Dalian Maritime Safety Administration, and China Ship Fuel Dalian Co., Ltd. The collaboration provided technical support and service guarantees for Dalian Port's first-ever green methanol ship-to-ship refueling operation.

Commissioned by China Ship Fuel Dalian Co., Ltd., CCS Wuhan Standardization Institute provided critical technical support for the LNG bunkering operation, delivering comprehensive services including plan formulation, risk assessment, and emergency response contingency planning. The institute's dedicated team overcame tight deadlines and heavy workloads with unwavering commitment, completing three technical reports on schedule. These documents not only established systematic implementation protocols and environmental requirements but also conducted thorough risk assessments, developing robust control strategies and emergency protocols. Approved by industry experts in July this year, the solutions ensured successful execution of the operation. This marks CCS's expansion into green marine fuel applications following its previous LNG support for Shanghai Port and Shenzhen Yantian Port, offering a "CCS Solution" to advance China's "dual carbon" goals in maritime logistics.

In recent years, the CCS has prioritized research on methanol refueling technologies for ships. It has successively released a series of guidelines including the "Guidelines for Ship Methanol Fuel Refueling Operation " and "Guidelines for Methanol Fuel Refueling Vessel ", providing the industry with safe and reliable technical support for methanol refueling operations. Moving forward, the CCS will continue serving the green and low-carbon development needs of the industry by conducting in-depth research on key technologies for marine new energy applications and refueling operations. This commitment aims to safeguard the green transformation and high-quality development of China's shipping industry.
