prO Diesel and gas engines generator sets and propulsion ...

1 2020 Rolls-Royce, with the Bergen engine range is a leading developer and manufacturer of medium speed Diesel and gas propulsion engines and generator sets . Since 1946 we have developed and installed thousands of units, meeting the requirements of ship owners and land-based installations for robust, reliable and economical power. In the 1980s we developed our lean burn combustion system and applied it to engines using various types of gas as fuel. This has been further refined on our latest gas engines , providing leading thermal efficiencies with high power density and low the marine industry is increasingly turning towards burning natural gas for propulsion , Bergen gas engines have built an unrivalled track record in powering ships, and reducing exhaust emissions of carbon dioxide, NOx, SOx and engines are available in the 1,800 8,000kW power range and gas engines from 1,400 7, and gas enginesgenerator sets and propulsion systems21 Marine engine anD propulsion SySTeMSB32:40 BL and BV-series: Produced in 6,8 and 9 cylinder in-line, and V12 and V16 versions.

There is growing pressure to reduce CO2 and IMO Tier II regulations on NOx emissions will be superseded by much tougher Tier III limits in 2016. Both Bergen Diesel engines and Bergen gas engines are designed for marine propulsion and auxiliary duties.

4 The B32:40 and C25:33 Clean Design Diesel engines meet IMO Tier II requirements without additional off-engine clean up. The B35:40 and C26:33 gas engines have NOx emissions lower than the strict Tier III limits with lower CO2 equivalent emissions.*Bergen gas engines have been in marine service for seven years. Vessels as diverse as roro ships, feed supply vessels, ferries, tugs and offshore supply vessels are now in-service or on order with Bergen gas engines . Gas tanks and the gas supply system to the engine are established technology, within the Rolls-Royce scope of many applications the gas engine is becoming a natural choice. CO2equivalent emissions are reduced by 22 per cent compared with engines burning liquid fuel, NOx emissions are cut by 92 per cent, while emissions of SOx and particulates are negligible. The design of the Bergen C26:33 cuts methane slip to very low Systems can be included into Rolls-Royce scope of emission for Bergen engines2424 Marine liquid fuel enginesRatings are according to ISO 3046-1, at maximum 45 C ambient air temperature and maximum 32 C sea water temperature.

5 Specific fuel oil consumption is based on MDO with a net calorific value of MJ/kg and no engine driven pumps. For each engine driven pump, there is a need to add 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) marine gas engines comply with IMO Tier III with no need for a SCR fuel oil operationThe engines are designed for operation on heavy fuel oil with viscosity up to 700 cSt at 50 C ISO 8217 RMK77. Ratings will be specified subject to type of gas enginesThe marine gas engines give the following reductions in emissions compared with diesels IMO Tier II: 92% NOx, net 22% greenhouse gases and close to zero SOx and particulate matter. Marine gas engine ratings are according to ISO 3046-1, at maximum 45 C ambient air temperature and maximum 32 C sea water temperature. Specific fuel gas consumption excluding engine driven pumps is based on reference natural gas with Methane number above 70 and net calorific value of 36 MJ/nm3.
