Mariso Corporation

Mariso Corporation began its journey in 1994, and today, it’s one of the most widely recognized names in marine engine parts and technical repair services. Headquartered in Shanghai, the company didn’t stay local for long. It quickly grew and now operates with a global footprint - with locations in places like Tianjin, Guangzhou, Hamburg, Piraeus, Houston, Cyprus, Turkey, and Ho Chi Minh City. With a team of more than 200 people, it continues to support shipowners and operators with practical solutions to real-world challenges. The core of what Mariso does revolves around the supply of marine engine parts - everything from main and auxiliary engine components to turbocharger spares, air compressors, and pumps. And they don’t just sell parts; they stock them in key global locations like Houston and Shanghai, so deliveries can happen quickly - something ship operators value when time is tight and downtime is not an option. Mariso is also known for its repair and reconditioning services. Their teams handle everything from turbocharger overhauls and chemical cleaning to blade blasting, rotor balancing, and exhaust valve servicing. In fact, many of their technicians have trained with or worked for major names like ABB and Wärtsilä, so customers know they’re getting real expertise. They’ve also invested in their own equipment and workshop capabilities, enabling them to recondition large, critical parts with precision. Many of these services are approved by Lloyd’s Register, and they carry ISO 9001:2000 certification as a further sign of quality. After nearly three decades, Mariso’s focus hasn’t changed - reliable parts, fast service, and hands-on support from people who know ships inside and out.
