Siemens presents its low-emission natural gas engines for the marine sector

Siemens presents its new engines powered by Liquefied Natural Gas with a high-speed generator set for electrical propulsion, generation for the marine sector, in one of the most important international fairs of the sector, Asia Pacific Maritime, which will be held from 14 to 16 March in Singapore. This new family of engines and generator sets from Siemens also allows the supply of auxiliary power to ships moored at port. Among their many advantages, these engines stand out for not emitting soot particles or sulphur oxides (SOx), as well as producing 80 percent fewer NOx emissions and 10 percent fewer greenhouse gas emissions compared to conventional supply. Moreover, they are quieter and produce less vibration.
This range of engines was created at the company’s flagship research and development centre located in Miñano, in the province of Alava, Spain, and it is expected to be put into operation in the seas of Europe and Asia. In addition, these gas engines have power range configurations of 6 and 8 cylinders in-line and 12 and 16 cylinders in V. and are available in 1,500 and 1,800 rpm from 275 to 935 kWb (320 to 1,110 kVA). As with other Siemens engines, they are designed to offer high reliability and availability.

The Liquefied Natural Gas Alternative

Siemens has supplied diesel engines for years to fleets for propulsion, power generation and auxiliary equipment, since they have always met the highest emission requirements in the use of fishing vessels, tugboats, research ships, tankers, barges, cargo ships, ferries and dredges. However, with the new emissions limitations of IMO's NOx Tier III, Liquefied Natural Gas is becoming another of the fuel alternatives most required by the maritime sector. This is because it is able to comply with current legislation without having to carry out subsequent treatment of the exhaust gases. It would follow that these demands have also been included within the emission control areas (ECA) that include the North Sea, the Baltic Sea, and the East and West coasts of the United States and Canada. This has generated greater interest in this fuel.
In fact, the European Union is promoting the development of marine engines that can use Liquefied Natural Gas as well as investments in the necessary infrastructures to be able to transport and distribute it. This, together with the new emission restrictions and the high availability and reliability of the gas engines, make these engines one of the main choices for equipment operators. In order to respond to the demands of the sector and offer a wide range of products that cover all needs, the company has created this new family of engines powered by Natural Gas. This will provide the marine sector with a wide range of power supply types according to its preferences.
The industry is faced with a series of challenges when it comes to developing this type of engines, namely, strict safety requirements and a relatively small market. It is also important to consider the lack of adequate infrastructure for the supply of fuel and the fact that the regulations for the loading of liquefied natural gas fuel are still in process.

An international provider with more than half a century of experience

The new business of the Power and Gas Division of Siemens, Siemens Engine Business (SEB), solves many of the marine industry issues with the creation of tailor-made solutions and with a wide range of engines for the supply of power. This, together with Siemens' strong investment in R&D&I and its experience accumulated over more than 50 years, make Siemens Engines a leading international technology supplier of both diesel and gas fuel engines, for a broad spectrum of applications and activity sectors.
Its products include high-efficiency, low-emission gas and diesel engines, which can be used for different applications such as cogeneration, electricity generation, waste to energy, propulsion and generation for marine applications, etc. These engines use the latest fuel injection and supercharging technologies, which boost their power, reduce their fuel consumption, and optimise their maintenance costs. They can be powered by natural gas, biogas, landfill gas, sewage gas, synthesis gas, well gas and a wide variety of other gases, thus covering a wide range of industrial sectors.
SEB has its factory in Zumaia (Guipúzcoa) Spain, dedicated for more than half a century to the design and manufacture of high-performance engines that are exported throughout the world, mainly to countries such as Argentina, USA, , Morocco, Turkey, Pakistan, Singapore, Indonesia, Bangladesh, Vietnam, South Korea, Malaysia, Australia and of course, all around Europe. The range of power offered by the SEB portfolio ranges from 150 to 2065 kW for gas engines/generators, while the range of diesel engines/generators ranges from 184 to 1324 kW.
