Naval and Maritime expertise

In the marine industry, controlling nuisances and complying with standards (IMO Tier III, Stage V) are essential. Backed by 60 years of expertise, Groupe Boët offers acoustic and emission treatment solutions adapted to marine environments. Our complete exhaust systems combine noise reduction, engine pollution control and optimization of pressure drops. Robust and modular, they meet the most demanding technical requirements of the naval sector.

Marine engineering: complete exhaust line treatment

The Groupe Boët specializes in the complete treatment of marine exhaust systems, meeting three major challenges:
noise reduction, exhaust gas depollution and optimization of pressure drops.

Multi-criteria performance for marine applications

Our systems provide marine engine pollution control in compliance with the most stringent international standards:

  • Reduction of NOx, CO, HC and PM

  • Integrated technologies: SCR (Selective Catalytic Reduction), DOC (Diesel Oxidation Catalyst), DPF (Diesel Particulate Filter) and ASC (Ammonia Slip Catalyst)

  • Compliance with IMO Tier III and EU Stage V standards

Our solutions are robust, modular and compatible with a wide variety of marine engines and onboard applications. Each system integrates real-time monitoring and precise control.

Marine engine noise reduction

We design custom acoustic systems, guaranteeing noise reduction of up to 60 dB(A).
Our approach is based on :

  • Advanced acoustic simulation (ANSYS, SIDLAB) of the complete line: manifold, SCR, silencer, chimney

  • Analysis of component interactions for maximum efficiency

  • A range of standard or customized silencers, adapted to the requirements of each ship

Optimizing pressure losses

Thanks to CFD (Computational Fluid Dynamics) analyses carried out with Discovery and Fluent, we optimize flow dynamics to reduce pressure losses, while maintaining optimum energy performance throughout the line.

Comprehensive support: from design to installation

As a designer and manufacturer, we provide complete project management, from sizing to installation:

  • Turnkey solutions for OEMs and shipyards

  • Compact, easy-to-integrate systems

  • Simplified maintenance

  • DNV and BV MARINE certifications ensure the reliability and conformity of our products
