Engines for a better environmentDiesel & gas engines

Rolls-Royce provides complete diesel or gas-powered propulsion systems ‘from the bunkering flange to the propeller thrust’.

There is a proud tradition behind the Bergen engine series.Since 1943 we have developed, manufactured and installed medium speed engines, meeting the requirement of ship owners and operators for robust, reliable and economical engines. Our engines meet the most stringent environmental requirements while delivering high performance. The marine diesel engines comply with the requirements of the IMO Tier II without any external cleaning system. IMO Tier III is met by the use of a Selective Catalytic Reactor (SCR) system.

The new B33:45 diesel engine range offers industry leading fuel consumption and emission figures, for mechanical propulsion and electrical generation.

Its design was developed after consultation with a broad range of operators to establish what qualities they prize in an engine. The clear first priority was reduced life-cycle costs. The other feedback focused on five main areas;

• achieving the lowest fuel consumption and emissions• highest power per cylinder in this engine class• increased power within the same footprint, and potential for fewer cylinders with lower weight and cost• a compact modular design and a base engine suitable for liquid or gas fuel• dynamic and extended service intervals

These engines are economical down to very low loads, without visible smoke.

Rolls-Royce was a pioneer in developing modern lean burn gas engines, and the first Bergen gas engine went into service in 1991. Since the introduction of the Bergen lean-burn technology more than 650 gas engines have been delivered and over 23 million operating hours accumulated.

Engine technologyDiesel & gas engines

Diesel enginesBergen marine engines are supplied both for mechanical transmission, driving the propeller through a reduction gear, or as complete generating sets for electric propulsion or power generation.

Our engines are known for their durability and mechanical strength. In addition they provide maximum reliability, ease of maintenance and a proven low life-cycle cost. All Bergen engines are designed under a common design philosophy with focus on optimum load response, optimal fuel economy and meeting emissions regulations.

Optimum load response is based on the Pulse turbocharging system. This enables the engine to respond rapidly to load changes, and offers high performance under normal part load operation. Safe and reliable operation is due to the Bergen Cofferdam system, preventing no fuel leakage into the main oil lube system and minimising lube oil consumption.

Gas enginesDesigned from scratch to be clean, quick to respond, and very fuel efficient, our gas engines have proven their reliability over millions of running hours.

Rolls-Royce gas engines have proven themselves to be the cleanest, most efficient piston engines on the market. The highly reliable Bergen C-series gas engines and the larger B-series (in-line configuration) and BV-series (Vee-configuration) engines represent the latest in lean-burn gas technology, delivering rapid response times and long intervals between overhaul.

Bergen gas engines have been designed from the outset for variable speed and variable load operation, and to respond as well as their diesel counterparts. They are classification society-approved for both constant speed generator drive and for direct mechanical transmission to the propeller or thruster.

The lean burn spark ignition Otto cycle technology used in the Bergen gas engine has been developed continuously over the last 25 years. The result is a very efficient engine where approx. 50% of the energy in the fuel is translated into shaft power. Engines can accept wide variations in gas methane number, operating cleanly and efficiently with a high gas quality tolerance.

Compared to the equivalent Bergen diesel engines, the Bergen gas engines give E2 weighted emission reductions of 92% NOx, close to 22% in CO2 and virtually eliminate SOx and particulates, already meeting enforced IMO Tier III and EPA Tier 3 requirements and are subject to EPA Tier 4 certification.

Great effort has been made to enhance maintenance friendliness and to make it easy to keep clean.

General description The new Bergen B33:45 engine from Rolls-Royce carries forward the Bergen range of diesel and gas engines, offering 600 kW per cylinder in a compact engine design. The new engine range offers industry leading fuel consumption and emission figures, for mechanical propulsion and electrical generation.Its design was developed after consultation with a broad range of operators to establish what qualities they prize in an engine. The clear answer was life-cycle costs.

The designers focused on five main areas• achieving the lowest fuel consumption and emissions• highest power per cylinder in this engine class

• increased power within the same footprint, and potential for fewer cylinders with lower weight and cost• a compact modular design and a base engine suitable for liquid or gas fuel• dynamic and extended service intervals

Vee engines and gas engines sharing many of the design features will follow.

Industry-leading fuel consumption and reduced emissionsSpecific fuel oil consumption is 175 g/kWh at 85% MCR and 177 g/kWh at full load. These engines are economical down to very low loads, without visible smoke and comply with IMO Tier II and Tier III rules.

Compact and modularised designThroughout the B33:45 a modular design approach has been employed, giving an engine that is rational to produce, resulting in a competive cost per kilowatt and straightforward overhauling. The crankcase is designed to incorporate air and oil galleries to minimise the number of external pipes with increased stiffness of the engine block. The design ensures very low levels of vibration. The crankcase carries the fully balanced crankshaft which has bolt-on balance weights and is dimensioned so that full power can be taken from either end up to and including the V12 version. Variable valve timing gives optimum response to load changes with reduced visible smoke even at low loads.

Dynamic service intervalsB33:45 engines are designed for 25,000 hrs between major maintenance when operating within a defined load window. Using health monitoring can enable engine overhaul intervals to be aligned with vessels’ re-classification.

Typical applications: • Anchorhandler

tug supply vessels• Subsea construction vessels• Drill ships• Semi-submersibles• Seismic survey vessels• Accomodation units• Heavy lift ships• RoPax ferries• Cruise vessels• Cargo ships• Fishing vessels

Power range for the Bergen B-platform gas

The need for vessels to meet increasingly demanding emission levels, particularly near coasts, has seen a rapid rise in the popularity of LNG (liquefied natural gas) and a corresponding increase in availability. With some countries now offering tax incentives for low emissions, LNG is set to become an important marine fuel of the future.

Bergen lean-burn gas engines are designed to burn LNG and are derived from the robust Bergen B diesel range. They share many common components, but with an increased cylinder bore of 350mm. Bergen B-series in-line and C-series gas engines are currently in development and available from 2011.

For marine gas engine installations Rolls-Royce also provides gas handling and storage systems, together with a full range of equipment to provide complete propulsion system solutions ‘from the bunkering flange to the propeller blade’. The double-piped gas fuel system allows a standard engine room solution, with no need for separate engine compartments.

Engine type

C-series gas engine.Lean-burn technologyRolls-Royce was a pioneer in developing modern lean burn gas engine technology, which it has applied to several hundred engines. A lean-burn engine operates on the Otto cycle with mixture com-pression and an external ignition source. A rich gas/air mix in a precombustion chamber is ignited and forms a strong ignition source for the very lean mixture in the cylinder for knock-free combustion. This allows the cylinder power to be greatly increased with high efficiency and reduce emissions.
