MTU drive system promotes the development of green technology in shipbuilding industry
At the international maritime trade fair SMM on September 2016 6~9, Rolls Royce presented a new MTU drive system.
The system is designed according to the International Maritime Organization (I - MO) III emission standards and the U.S. Environmental Protection Agency (EPA) emissions regulations Tier4 for commercial ships, offshore ships and military vessels standard. CEOUlrichDohle, Rolls Royce power systems, said: "with our latest leading diesel and gas engines and the existing excellent drive system, we will provide the latest green high-tech solutions for our shipbuilding industry in the next few decades." In addition, Rolls Royce demonstrated a range of existing medium speed marine engines, bridge systems, propellers and so on.
With a series of technical innovations in turbocharging system, combustion process and fuel injection system, MTU will launch 4000 series engines in the market in 2018. The 4000 series has now been further optimized and will provide better performance (1.380~3.200 kW) for working ships, offshore ships, ferries and government vessels. To this end, MTU will be the first launch of the series 20 cylinder engine. At the same time, MTU also developed a new SCR waste gas reprocessing system, which will meet the IMO III and EPATier4 emission standards, reduce about 75% of NOx emissions and 65% of respirable particulate emissions, and do not need additional fuel particle filtration. In 2017, the 4000 series of engines for yachts will be launched in the market with the improved MTU SCR system, and it will meet the IMO III emission standard.
MTU drive system and SCR waste gas reprocessing system constitute an integrated system, which meets the requirements of IMOTier III and EPATier4, and will bring benefits to customers in a reasonable manner. The system provides the best power under the premise of equal weight with the smallest placement space. The exhaust gas treatment system is highly compact due to the integration of the reactants prepared in the SCR box. Unlike the usual, MTU's SCR system is not pre-set, but adjustable. It measures the maximum and minimum emissions of the SCR system and precisely regulates the amount of reactant entering the system.
The new MTU gas engine applied to the ship has successfully completed the 3000 hour bench test and will be on display. Rolls Royce power system company CEOUlrichDohle said: "now we can be sure that this gas engine is not only up to our own standards, but also to meet the needs of customers. Its excellent acceleration and performance can be comparable to diesel engine, economical, reliable and environmentally friendly." In 2018, Rolls Royce's first approved gas powered marine engine will be used for commercial ships. The engine will meet the IMO III emission standard without additional exhaust gas treatment. Due to its excellent dynamic acceleration, less environmental pollution, higher reliability and economy, the new MTU gas engine is very suitable for tugs, ferries, pusher boats and special purpose vessels, such as inspection vessels.
In SMM, MTU will also show an advanced diesel generator for submarines, based on a 4000 series engine with 1300 kW of power output, the first batch of this year to start production. It is designed to make full use of lithium-ion battery technology, significantly reducing charging time. Because of the lower fuel consumption of this new generator, the submarine will have a wider range of work under the same size fuel tank.
As a provider of power system devices, MTU also has the capability to develop production driven solutions, including ship automation systems. MTU will exhibit a ship model with a self-developed drive system, which combines diesel engines and gas turbines with the highest efficiency and flexibility. At the booth, this system is combined with Callosum. Callosum is the latest and user-friendly automation system developed by MTU, which can monitor and optimize the operation of ship drive system and all shipboard systems. It has proven its excellent results in the Navy and coast guard missions.
There will also be a model based on the 4000 series of generators. This product is used as a diesel power driven unit or commercial ship generator, will be mainly used for offshore oil and natural gas transportation and other commercial applications. The generator consists of a series of 4000 series of 8 cylinder, 12 cylinder and 16 cylinder "Iron - men" engine, a generator, and an electronic control system. They are all mounted on a common base frame, providing 720 to 2140 kilowatts of power output.
As a partner of the power system of the shipbuilding industry, Rolls Royce also provided comprehensive services for the MTU products customers to cover the whole service cycle of the power system. MTU's value caring principle, as well as customer specific maintenance policies, also covers fast replacement parts supply, as well as coolant, lubricating oil, filters and other consumables. In addition, MTU also provides data and evaluation on the official website, providing remote services to support the effective operation of the ship, and optimize maintenance services.
