MTU launches a combination of propulsion systems for special vessels

Recently, during the Norwegian International Maritime Exhibition held, Rolls-Royce's MTU company exhibited its propulsion system portfolio mainly for offshore support vessels (OSV), workboats and ferries.

The company's engines include 2000, 4000 and 8000 series propulsion engines ranging from 400 to 10,000 kW, hybrid propulsion solutions and diesel-electric propulsion systems, and diesel generator sets that power ships.
Rolls-Royce exhibited the MTU 4000 series diesel engine that meets IMO III and EPA Tier 4 emission regulations. In addition to the new catalytic converters developed by MTU, this fifth-generation 4000 series diesel engine will use various advanced technologies to meet emission requirements in the supercharger, compression process and fuel injection system.
In addition to comprehensive solutions that meet IMO III and EPA Tier 4 emissions requirements, including MTU's propulsion systems and selective catalytic converter exhaust aftertreatment systems, users will benefit from having a best-matching system. In terms of power to weight ratio, the system requires minimal installation space and is very flexible.

MTU's new 16-cylinder gas engine for workboats will be available in 2018, with an expanded power range from 1,500 kW to 2,000 kW. Next, an 8-cylinder gas engine covering the company's range of 750 to 1,000 kW will be introduced.
Due to its dynamic acceleration characteristics, its environmental compatibility, reliability and economic operation, it is ideal as a main propulsion device for tugboats, ferries, pushers and special vessels such as research vessels. Its combustion concept will provide efficient use of fuel and ensure that IMO III emission standards are met without the need for an exhaust aftertreatment system. To meet the requirements of the EPA Tier 4 regulations, a compact oxidation catalyst is installed on the engine. Thanks to the double-wall air supply duct, the cabin can be designed in the same cabin as the diesel engine.

Round Bar

Round steel is a kind of cylindrical metal material, which is widely used in construction, machinery manufacturing, automobile manufacturing, energy, transportation and other industries.
Round steel is mainly made of carbon steel, alloy steel and tool steel.
Among them, carbon steel round steel refers to steel with carbon content within the range of 0.20% to 0.55%.

Carbon steel round steel is an economical and practical structural material with good weldability, plasticity and machinability.
Alloy steel round steel refers to the steel with a certain amount of alloying elements (chromium, manganese, cobalt, boron, molybdenum, vanadium, etc.), which can obtain higher strength, hardness, corrosion resistance and wear resistance.
Tool steel Round steel is a kind of high-speed tool steel material, which has the advantages of high hardness, high red hardness and wear resistance.

The production process of round steel is very diverse, including hot rolling, cold drawing and cold drawing.
Among them, the hot rolling production process refers to the steel material heated to a certain temperature, plastic deformation through rolling machinery and equipment, pressed into different specifications of the shape of steel.
The cold drawing process is the use of steel wire material for cold drawing, which can obtain a higher surface finish for the production of precision parts.
Cold drawing process is to draw steel in cold storage to obtain higher density, hardness and strength.

The wide application of round steel lies in its material characteristics and production process, which can meet the needs of different industries.
In construction projects, round steel is mainly used to build steel structure houses, large factories, Bridges, oil drilling platforms and oil mining equipment.
In the machinery manufacturing industry, round steel is mainly used to process gears, bearings, connecting rods, pins, shafts and other parts.
In the automobile manufacturing industry, round steel is mainly used to make auto parts, frames, suspension systems, guiding mechanisms and so on.
It is also widely used in energy, transportation and other industries.
