The Accelleron company introduced the next generation of turbochargers for two-stroke engines, the X300-L series. The platform-based, easy-to-service concept complemented by Accelleron’s digital Turbo Insights technology sets a new benchmark for turbocharging that will give ship operators the flexibility to respond to uncertainty about the fuels they will use and how their ships will operate. boats in the future.
The benefits of the X300-L series, which currently comprises the ACCX365-L and ACCX370-L models, derive from its compact platform-based design, making it easy to maintain and adapt to different requirements that may evolve from a increasing variety of fuels.
Accelleron’s X300-L series sets a new standard in turbocharging with its compact design and easy service
This new turbocharger design means the entire rotor sub-assembly can be changed in a single port call, using a new or remanufactured cartridge.
The X300-L’s improved serviceability means turbocharger overhaul is no longer tied to dry dock schedules. Instead of servicing turbochargers every five years, port swapping means full runtime can be used between overhauls, resulting in just three scheduled services instead of four in a 25-year life years. This reduces operating costs and gives operators greater flexibility in their service regimes.
Digitally enabled technologies are also becoming increasingly relevant to advanced servicing models that allow cartridges to be used on individual vessels and potentially even on different owners. The X300-L series is fully enabled with Accelleron Turbo Insight, giving operators the ability to identify performance improvement opportunities and identify when service will be needed well in advance and helps Accelleron judge maintenance needs based on at the exhibition.
The platform-based concept is essential to provide flexibility to adapt to future requirements. The series has been designed with allowance for the even higher pressure ratios that new fuels might require. As a result, fuel-specific turbocharger building blocks can be more quickly incorporated for new-build projects as well as upgrading existing stock.
Improvements in power density in combination with the single cartridge concept lead to greater flexibility for the X300-L in engine layout. Concept studies have shown the feasibility of turbocharging an engine with a twin arrangement in which two X300-L type turbochargers are applied per intercooler instead of one large conventional type without fundamentally changing the engine design concept.
By doing so, the benefits of port call cartridge exchange can be extended to larger engines and vessel types. In addition, turbocharger cut-out options are increased, leading to tangible fuel savings.
The first X300-L turbochargers are expected to be delivered by the end of 2025 with the first orders to be taken in the second half of 2024.
