Modular Design for Maximum Versatility
Bergen’s B-series, rooted in a modular design, epitomizes adaptability, catering specifically to the demands of the marine market. Crafted following extensive consultation with marine operators, designers, and shipbuilders, this series debuted in 2014 with a diesel version, later complemented by a gas iteration in 2018. Offering a range of configurations, including inline or V-cylinder variants, the B36:45 seamlessly integrates into marine propulsion systems and auxiliary power generation setups.
Pioneering Efficiency for Maritime Solutions
Bergen’s latest B36:45L engine, honed through decades of maritime expertise, redefines efficiency for marine applications. Engineered in collaboration with marine stakeholders and service experts, it introduces advanced features such as Cylinder Pressure Monitoring (CPM) for precise load control, Variable Valve Timing (VVT) for optimized response, and a wastegate turbocharger ensuring optimized fuel-to-air ratios at varying ambient conditions for lean-burn operation.
For ship owners, the B36:45 engine boasts remarkably low emissions of NOx, CO2, SOx, and particulates. Featuring no smoke emissions and equipped with double-wall piping, vessels equipped with Bergen’s technology ensure cleaner engine rooms and provide operators with enhanced safety against gas-related hazards.
Key Benefits of Bergen's B36:45L
- Easy Installation
- Resilient Mounting - No need for welding brackets
- Aligned Piping at Pump-End for Easy Connection
- IMO Tier III Compliant without SCR
- Single Fuel = Single Bunkering
- Fast Load Response
