Market: More than 100,000 large ships ply the world's oceans. Of these, roughly 45,000 are freighters transporting goods around the world. There are some 8,000 cruise ships, as well as many ferries and tugboats.

Turning point: Until quite recently, the acquisition cost of a ship was roughly three times as high as the cost of fuel over its service life. Now, however, this ratio has been turned on its head, and a ship's fuel consumption now plays the most significant role. In addition, fuel prices are very volatile.

Legislation: In coastal waters and on rivers, vessels will have to comply with strict emissions standards in the future. In many cases, this is only possible with additional exhaust-gas treatment. The North Sea, Baltic Sea, and U.S. coastal waters are examples of such “emission control areas” (ECA). On the high seas, by contrast, the main concern is to cover distances as economically as possible.

Portfolio: Bosch offers solutions that make ship technology efficient and low in emissions. The focus here is on low-emission waterborne transport. Its portfolio ranges from common-rail systems for yachts, container ships, and cruise ships to low-emission, economical engines running on diesel and natural gas.

Service: Bosch offers not only components but also a global service network that can quickly make spare parts for ships available. This reduces turnaround times, and consequently also the costs related to downtime.

From yachts to freight: Bosch technology by type of ship
Yachts: For engines with an output of between 500 and 2,000 kW, injection components from the truck sphere are used. This means that Bosch can draw on the entire systems competence of its automotive business. A 2,200 bar Bosch common-rail system can help yacht-owners achieve fuel savings of more than 5 percent compared to its predecessor (common-rail system with 1,600 to 1,800 bar). For the 300-kilometer crossing from Genoa to St. Tropez, for example, this would mean a saving of roughly 200 liters of diesel.

Inland shipping (1): In Germany, the focus here in especially on freight transport. Up to 240 million metric tons of goods are transported on inland waterways in Germany every year. This is equivalent to roughly 14 million truck loads.

Inland shipping (2): For small freighters and large yachts, Bosch supplies its MCRS modular common-rail system, which delivers injection pressures of up to 2,200 bar. This system not only fulfils current emissions regulations, but is also well equipped for future requirements. It is used in diesel engines delivering up to 4,400 kW per power-generating unit. Bosch also supplies injection pumps and injectors for “dual-fuel” engines in which diesel injection is used to ignite natural gas in the combustion chamber. It is not only low consumption that makes this kind of powertrain attractive. When running on natural gas, emissions are very low. Nitrogen oxide emissions are reduced by 85 percent and particulate emissions by nearly 100 percent.

Inland shipping (3): For ships with engines as powerful as 5,000 kW – tugboats working in ports, for example, or regional ferries – Bosch offers a comprehensive range of exhaust-gas treatment systems from a single source. Bosch Emission Systems GmbH offers turnkey products: in addition to manufacturing components, the company in particular also handles their integration.

Cruises (1): For years now, cruise holidays have been enjoying double-digit growth rates. North America is by far the largest market. It not only has the world's largest cruise ports, but is also the seat of the world's leading cruise lines. As well as ocean-going cruises, cruise holidays on the North Sea and the Baltic are very popular, as are river cruises. Low-emission engines are especially important in this context. Bosch offers solutions designed for engines delivering between 5,000 and 10,000 kW.

Cruises (2): Bosch has injection components for cruise ships' dual-fuel engines. By combining natural gas and diesel, these engines can reduce particulate emissions to practically zero.

Freighters (1): Freighters are used to transport some 90 percent of goods traded globally. With nearly 4,000 ships, Germany has the world's third largest merchant fleet.

Freighters (2): Engines designed or retrofitted for dual-fuel operation and featuring Bosch injection components allow freighters to be run on inexpensive heavy fuel oil, natural gas, or marine diesel.

Freighters (3): Bosch also supplies injection systems for secondary engines delivering between 5,000 and 25,000 kW – engines that either support the two-stroke diesel engine or secure the ship's electricity supply. Most two-stroke diesel engines generate between 25,000 and 70,000 kW. In this regard, Bosch offers its customers not just components, but also services. For example, the company's experts help to precisely integrate the components into the overall powertrain, which varies from ship to ship.

Mobility Solutions is the largest Bosch Group business sector. In 2015, its sales came to 41.7 billion euros, or 59 percent of total group sales. This makes the Bosch Group one of the leading automotive suppliers. The Mobility Solutions business sector combines the group’s expertise in three mobility domains – automation, electrification, and connectivity – and offers its customers integrated mobility solutions. Its main areas of activity are injection technology and powertrain peripherals for internal-combustion engines, diverse solutions for powertrain electrification, vehicle safety systems, driver-assistance and automated functions, technology for user-friendly infotainment as well as vehicle-to-vehicle and vehicle-to-infrastructure communication, repair-shop concepts, and technology and services for the automotive aftermarket. Bosch is synonymous with important automotive innovations, such as electronic engine management, the ESP anti-skid system, and common-rail diesel technology.

The Bosch Group is a leading global supplier of technology and services. It employs roughly 375,000 associates worldwide (as of December 31, 2015). The company generated sales of 70.6 billion euros in 2015. Its operations are divided into four business sectors: Mobility Solutions, Industrial Technology, Consumer Goods, and Energy and Building Technology. The Bosch Group comprises Robert Bosch GmbH and its roughly 440 subsidiaries and regional companies in some 60 countries. Including sales and service partners, Bosch’s global manufacturing and sales network covers some 150 countries. The basis for the company’s future growth is its innovative strength. Bosch employs 55,800 associates in research and development at 118 locations across the globe. The Bosch Group’s strategic objective is to deliver innovations for a connected life. Bosch improves quality of life worldwide with products and services that are innovative and spark enthusiasm. In short, Bosch creates technology that is “Invented for life.”
