Recently, Zhejiang Energy Marine Environmental Technology Co., Ltd. (ZEME), a subsidiary of Zhejiang Energy Group, carried out desulfurization modifications on two container vessels belonging to Swiss-based Mediterranean Shipping Company (MSC). To date, the company has accumulated 420 ship sets of desulfurization orders, ranking third globally in order quantity. This year, ZEME has completed 95 ship sets of desulfurization modifications (new builds), surpassing the total delivered in 2022, setting a new historical record.

Desulfurization modifications for ocean-going vessels involve the installation of desulfurization devices on the exhaust gases of diesel engines burning high-sulfur fuel, significantly reducing sulfur oxide emissions during navigation. According to the International Maritime Organization's statistics from 2014, ocean-going vessels account for 13% of global SO2 emissions. By adding desulfurization devices, the impact on the global atmospheric environment can be further improved.

Since its establishment, ZEME has proactively collaborated with universities to conduct technological research and development, building China's largest ship exhaust pilot platform. In 2020, the company was recognized for developing the country's first set of hybrid ship desulfurization equipment. Through continuous research and testing on this platform, ZEME has formed a full series of desulfurization products tailored to different customers and application scenarios. As the lead organization in the project, the company won the First Prize of Zhejiang Science and Technology Progress Award in 2021.

In recent years, with the enhancement of technical competitiveness, general contracting capabilities, and global after-sales service capabilities, ZEME's market share has steadily increased, modifying over a hundred international and domestic vessels annually, with an annual reduction of over 400,000 tons of sulfur dioxide. To manage the vast amount of data, ZEME has independently developed an enterprise digital collaboration system, enabling the company's production management system to leap forward into high-level "digital management." This has significantly improved the company's management efficiency, shortening the single-vessel modification period from the industry-standard 60 days to 33 days, greatly reducing costs for ship owners.
