The Marintec China 2025, themed "Innovation and Cooperation for Sustainable Development of Maritime Industry", will be held from December 2nd to 5th, 2025 at the Shanghai New International Expo Center. Sifang Instrument showcased its online monitoring solution for ship exhaust emissions at the exhibition, providing one-stop gas analysis support for ship "combustion upgrade, navigation safety, and compliance emission reduction".

At the recently held COP30 conference, "blue carbon sinks" and the construction of marine ecological civilization became the focus, and the green and low-carbon transformation of the shipping industry is a key link connecting marine ecological protection and greenhouse gas emission reduction actions. As a brand with deep accumulation in both mobile and fixed pollution source emission gas monitoring, the three major gas analysis solutions exhibited by Sifang Instrument this time are a positive response to this trend.

1. Ship exhaust carbon emissions online monitoring system (CEMS)

With the increasingly strict requirements of regulations such as the Carbon Intensity Index (CII) of the International Maritime Organization (IMO), accurate and real-time accounting of ship carbon emissions is a necessity in the industry. Four party instrument ship CEMS can monitor key parameters such as SO ₂, CO ₂, CO, CH ₄, and flow rate in real time, intelligently sensing carbon emissions. The system is developed based on a mature platform that has obtained type certification from multiple classification societies, with excellent data accuracy and international credibility. It can effectively assist ship owners in meeting compliance requirements, optimizing energy efficiency management, and providing reliable data support for participating in carbon market trading.

2. Marine laser/infrared gas detection alarm

From traditional fuels to emerging LNG, methanol, and ammonia fuels, the risk of leakage is directly related to the safety of crew and ships. Sifang Instrument provides highly reliable laser/infrared gas detectors for areas such as cabins and computer rooms, which monitor in real-time the concentration of various toxic and flammable gases such as CO, H ₂ S, CO ₂, NH ∝, CH ₄, CH ∝ OH, etc., to prevent suffocation and explosion risks caused by oxygen deficiency or enrichment, and provide real-time alarms to empower safe navigation through scientific monitoring.

3. Continuous monitoring system for exhaust gas of ammonia fuel/methanol engine

As green fuels such as ammonia and methanol are key pathways for decarbonization in shipping, their combustion process is accompanied by the risk of NH3 escape and emissions of potent greenhouse gases such as N ₂ O. Sifang Instrument utilizes core technologies such as TDLAS, NDUV, and NDIR to accurately measure complex gas components such as NH3, NOx, N ₂ O, CH3 OH, and HCHO generated during the combustion process. This provides reliable data support for the development, optimization, and emission control of clean fuel engines, and safeguards the future of new fuel ships.

During the exhibition, the booth of Sifang Instruments attracted customers from China, the United States, South Korea, Singapore and other countries to stop and exchange ideas. All parties engaged in in-depth discussions on topics such as the policy orientation of green and low-carbon transformation in the shipbuilding industry, the intelligent application of gas monitoring technology, and future cooperation opportunities. Sifang Instrument showcased its professional product technology solutions, localized service advantages, and years of technical research and development capabilities through the exhibition, gaining widespread recognition from domestic and foreign customers and fully demonstrating the hardcore strength of domestic gas analysis instruments.

In the future, Sifang Instrument will continue to be driven by technological innovation, deepen its layout in the field of ship gas monitoring, provide high-quality gas analysis solutions for sustainable maritime development, and promote the shipping industry towards greenMoving towards a safe and efficient future.
