Accelleron has launched the ACCX300–L, a next-generation low-speed turbocharger for two-stroke marine engines, aimed at helping shipowners manage changing fuel, emissions and operational demands.
The new unit introduces a service-friendly cartridge concept that allows the full rotating assembly to be exchanged during port stays, removing the need to align major maintenance with drydock schedules. This approach enables servicing based on actual operating conditions, improving uptime and reducing off-hire periods.
Accelleron said the design cuts scheduled service events over a typical 25-year vessel life from four to three, while allowing full utilisation of component lifetimes and lowering overall lifecycle costs.
The ACCX300-L is built on a simplified platform architecture, reducing frame sizes from five to two. This standardisation is intended to ease spare parts logistics and support flexible configurations across different vessel types and engine setups.
The system also incorporates automatic turbocharger cut-in and cut-out functionality in twin configurations, helping maintain efficiency during low-load operations such as slow steaming by optimising performance and reducing fuel consumption.
Integrated digital capability enables continuous monitoring using onboard data, supporting condition-based maintenance and improved planning through Accelleron’s Turbo Insights platform.
