HLM Hertli Ltd.

Based in Switzerland, HLM Hertli is a specialized engineering and trading entity dedicated to the support, maintenance, and supply of the maritime propulsion sector. Founded with a distinct focus on technical competence, the company operates as an independent partner for ship operators and management companies that rely on medium-speed diesel engines. Its identity is deeply rooted in the Swiss tradition of precision engineering, leveraging a strategic location in Elgg and Aadorf to coordinate global logistics and technical services for the marine industry. The core of HLM Hertli’s operations revolves around ensuring the continued operational reliability of specific legacy engine series, most notably the Sulzer Z-type engines, including the Z40, ZA40, and ZA40S classifications. While major original equipment manufacturers often shift focus to newer technologies, HLM Hertli addresses the critical market need for sustaining older, yet vital, propulsion and auxiliary power systems. The company was established by a qualified marine engineer with extensive tenure at major engine manufacturing firms, providing the organization with an internal knowledge base that bridges the gap between theoretical engine design and practical, onboard troubleshooting. In the maritime and offshore markets, the company functions primarily as a provider of high-quality spare parts and technical consulting. Its inventory management allows for the rapid deployment of essential components, ranging from standard consumables to complex mechanical parts necessary for overhauls and emergency repairs. By sourcing and manufacturing parts within Switzerland and the European Union, the company ensures that components meet rigorous quality standards, offering vessel owners a reliable alternative for maintaining their assets. Beyond simple supply chain activities, HLM Hertli plays a consultative role. The firm utilizes its engineering background to assist clients with technical advice, maintenance planning, and the resolution of complex engine performance issues. This service-oriented approach places the company as a lifecycle support agent, extending the service life of marine vessels by ensuring their primary power plants remain efficient and compliant. Through its focused expertise and commitment to the "Swiss quality" ethos, HLM Hertli serves a niche but essential segment of the global shipping industry, supporting the fleets that transport goods across the world’s oceans.
