Bergen C25:33L - generating set

Product catalog summary

Overview: The document provides technical specifications and features of the Bergen C25:33L diesel engines, designed for marine propulsion, marine generating sets, and power generation. These engines are known for their cost-effective operation and have been in production for over sixty years.

Specifications: The engines are rated according to ISO 3046/1 standards, with performance based on ambient air temperatures of 0-45°C and seawater temperatures up to 32°C. They are capable of operating on heavy fuel with viscosities up to 700 cSt at 50°C, compliant with ISO 8217 RMH77.

Features: Key features include fast load response, stable frequency, silent operation, compliance with IMO Tier II requirements (except at 720/750 rpm), competitive fuel and oil consumption, no fuel leakage into the lubricating system, and a high power-to-weight ratio. The engines are service-friendly and supported by a global service network.

Technical Data: The engines are available in three types: C25:33L6A, C25:33L8A, and C25:33L9A, with 6, 8, and 9 cylinders respectively. They operate at speeds of 900/1000 RPM, with maximum continuous ratings (MCR) ranging from 1920 to 3000 kW. Specific fuel consumption is 182/185 g/kWh, and lubricating oil consumption is 0.7 g/kWh.

Dimensions and Weight: The engines have a cylinder diameter of 250 mm and a piston stroke of 330 mm. The dimensions and weights vary slightly depending on the engine type and alternator choice, with total weights ranging from 31,485 kg to 43,200 kg.

Additional Information: Waste heat recovery data is available upon request. The document notes that specifications may change due to continuous development.

Fact Sheet Diesel engines - world leading fast load response - extremely stabile frequency - super silent resilient mounting - Bergen C25:33L certified to meet IMOTier II requirements (except - competitive fuel- and lubricating oil - no leakage of fuel to lubricating oil - possibility of single bearing alternator - high power to weight ratio - power pack unit - proven low life cycle cost - service friendly - 24 / 7 support by Rolls-Royce global service network Technical data for the Rolls-Royce C-engine at 720 to 1000 rpm Engine ratings are according to ISO 3046/1 .The above figures are based on conditions of 0-45°C ambient air temperature and max. 32°C seawater temperature. Specific fuel oil consumption is based on MDO with a net calorific value of 42.7 MJ/kg and no engine driven pumps. If engine driven pumps, add 0,5% for each pump. Choose Rolls-Royce engines for cost-effective operation. For more than sixty years of operation, we have produced four stroke medium speed engines for marine propulsion, marine generating set and power generation to customers world wide. Heavy fuel operation The engines are designed for operations on Heavy fuel with viscosity up to 700 cSt at 50°C ISO 8217 RMH77. Ratings will be specified subject to type of application. Waste heat recovery Necessary data for arranging waste heat recovery plants (exhaust gas and cooling water) are available upon reguest. Due to continuous development, some data may be change without notice.
