The marine industry faces increasing pressure to meet stringent emissions regulations at both the international (IMO Tier III, MARPOL Annex VI) and regional (U.S. EPA, California CARB) levels. Compliance is especially challenging for older vessels and auxiliary systems originally built without advanced emission controls. This presentation will focus on the practical challenges and solutions for retrofitting marine backup generators and propulsion engines with diesel particulate filter (DPF) systems, specifically highlighting active aftertreatment technologies such as those developed by Rypos.
We will review the current regulatory landscape, focusing on requirements impacting diesel particulate matter (PM) emissions. Case studies will illustrate successful retrofits on marine applications, including auxiliary power systems, harbor craft, and passenger vessels. Attendees will learn about the engineering considerations for retrofits, including managing exhaust backpressure, integration with existing engine systems, durability in marine environments, and achieving reliable regeneration under variable load profiles. The session will also cover maintenance best practices and the long-term cost benefits of compliance retrofitting versus full engine replacement.
Key Learning Objectives:
– Understand evolving marine emissions regulations and compliance timelines.
– Explore the technical feasibility and benefits of DPF retrofits on marine backup and propulsion systems.
– Analyze case studies demonstrating real-world retrofits using active DPF technologies like Rypos.
– Identify design, installation, and operational factors critical to successful retrofit projects.
