Cost Effective Operation & Design
Developed through consultations with operators, designers, and shipbuilders, Bergen’s B33:45L offers cost-effective operation through modular design, delivering the efficiency and dependability we’re known for with the service-friendly design our customers appreciate.
The engine provides proven reliability with extended service intervals of up to 25,000 hours, minimizing downtime and maintenance costs. It meets IMO Tier II compliance without the need for Selective Catalytic Reduction (SCR) and achieves Tier III compliance with SCR, ensuring adherence to stringent environmental regulations. Additionally, its fast load response, low vibration, and structural noise levels ensure smooth and efficient operation in any application.
The B33:45 engine features full equipment health monitoring with 24/7 global service support, including emergency assistance and a comprehensive network of trained service engineers and workshops. The modular, low-weight construction allows for ease of installation and maintenance, with adaptable exhaust routing and aligned piping for straightforward connections. Our flexible design includes the capability to convert between diesel and gas operation via Bergen’s B3X Engine Platform, providing versatility in a futureproof solution for any future fuel type. Furthermore, its compact size and high power per cylinder make it ideal for small engine rooms, requiring fewer units to maintain.
Capable of operating on inclines up to 25 degrees, Bergen’s engines reduce the need for additional emergency generators, saving space, weight, and costs for our customers. The Bergen B-series is European-made with high-quality components, ensuring long-term reliability and efficiency. Its high power per cylinder and fewer units required for maintenance make it a trusted choice for ship owners globally, backed by Bergen’s commitment to excellence and sustainability.
