Welcome to Li Marine Services

Li Marine Services is a U.S.-based marine technical specialist headquartered in New Orleans, Louisiana, focused exclusively on ballast water treatment system (BWTS) and exhaust gas cleaning system (EGCS) support for vessels operating in U.S. waters. We partner with shipowners and operators who demand precision, reliability, and absolute confidence in regulatory compliance.

Our strength lies in deep technical expertise and disciplined execution. Our core team of seasoned marine engineers brings over six years of intensive field experience, having successfully completed hundreds of BWTS and EGCS service engagements across the United States. This extensive hands-on background enables us to diagnose issues with speed and accuracy, implement effective solutions, and ensure systems perform to the highest standards under real operating conditions.

We maintain particular strength in servicing leading BWTS manufacturers, including Sunrui and Headway, while also supporting a broad range of internationally deployed systems. This cross-platform capability allows us to deliver consistent, high-quality service across diverse fleets with minimal operational friction.

Li Marine Services provides a full spectrum of technical support—from commissioning and advanced troubleshooting to preventive maintenance, statutory inspections, and performance optimization. Every engagement is approached with a commitment to technical excellence, operational efficiency, and uncompromising service standards.

For our clients, this means more than service delivery—it means reduced downtime, assured compliance, and the confidence that critical environmental systems are in expert hands.
