MTU PROVIDES GREEN SOLUTIONS FOR PROPULSION SYSTEMS OF SUPERYACHTS.
Guests and owners aboard the 87m Feadship superyacht Lonian are now enjoying even greater convenience on the water. The new Hodor Alu Cat shadow vessel is tailor-made for the needs of guests aboard the superyacht, transferring guests safely, extending the list of leisure activities available, and offering loads of space for the ferrying crew members or extra supplies and equipment. At 66m long, the vessel accommodates twenty crew and staff members, with sufficient deck and storage space for supplies and sports equipment. The design even boasts a submarine garage and helipad. Hodor was designed by Australian company Incat Crowther and built by Spanish shipyard Astilleros Armón in their fully-enclosed Burela location. The vessel is powered by two MTU 16V 4000 M73L main engines, rated at 2832 kW output and reaching maximum speeds of 22.5 knots and able to cruise at 14 knots on long-haul passages of up to 5,500 nautical miles. The MTU SCR system for exhaust gas purification is specially adapted to MTU engines and complies with the current IMO III emissions directive, reducing polluting NOx emissions by a significant margin. Thanks to the efficient multihull design, only 160,000 liters of fuel are needed to achieve the vessel’s maximum range. The hull has an inverted bow, a carrying capacity of 240t, and a low propeller pull of 3.1m. Particularly created for the significant reduction of NOx emissions, MTU uses a technology >>
MTU Hybrid systems for ships
Expected as of 2021, Rolls-Royce will launch a range of hybrid ship propulsion systems in series onto the market. The propulsion systems will also be made available for yachts, work boats, and ferries, in a power range extending from around 1,000 kilowatts to 4,000 kilowatts per powertrain.

Hybrid System.
Rolls-Royce will be offering hybrid propulsion systems from MTU in series for ships, consisting of MTU internal combustion engines, electric drive modules, transmission systems, batteries, monitoring and control systems, in addition to other electronic components.
As per 2021, systems incorporating MTU Series 2000 engines combined with variable electrical power will be launched on the market and will cover a power range of between approximately 1,000 and 2,200 kilowatts per power train. Rolls-Royce will then gradually extend its portfolio, with the addition of hybrid systems based on the power delivered by MTU Series 4000 engines and variable electrical power that will cover a power range of between approximately 1,000 and 4,000 kilowatts per powertrain. Rolls-Royce will focus on PTI solutions. At one PTI solution, the gearbox is connected to the diesel engine via a clutch. An electric motor is attached to this PTI gearbox that can be coupled or decoupled as needed.
For yachts or passenger ships, a high power output on the one hand and a significant increase in comfort levels resulting from the silent, vibration and emission-free cruising on the other, are certainly of interest. Alongside high power output, hybrid propulsion systems can provide yet other economic benefits for applications with very high requirements in terms of speed and performance or a widely varying demand for power. Temporarily entirely emission-free cruising is possible when operating in the battery mode. Another important economic advantage for operators is the option to optimise the utilisation of all components involved in the system via intelligent and optimised system control and integration, thus extending maintenance intervals.

called Selective Catalytic Reduction (SCR). SCR is a technology that injects urea into the exhaust stream, where a catalyst then helps to convert nitrogen pollutants into harmless nitrogen, carbon dioxide, and water vapor.
Bilgin’s Tatiana In February 2020, the first hull of Bilgin 263 series, Tatiana – with model name NB75 – entered sea trials phase. As the largest yacht ever built by a Turkish shipyard so far, the superyacht has more than met performance expectations during her sailing in Istanbul. With the first trials made for the yacht’s twin MTU engines, the yacht achieved the expected maximum speed of 19+ knots. Tatiana demonstrated a smooth driving behaviour during the trials. The Turkish shipyard Bilgin is currently building three 80m yachts, all fitted with MTU IMO III propulsion systems. The Bilgin 263’s twin MTU Series 4000 V16 engines can power it up to a top speed of 20 knots, making it faster than its predecessors. Its MTU SCR system ensures the yacht stays within IMO Tier III exhaust emission limits. The integrated IMO III solution – consisting of an SCR exhaust gas aftertreatment system perfectly tuned to the propulsion system – offers flexible installation options and is easy to maintain. It requires a minimum of installation space and features an excellent power to weight ratio. The MTU SCR system is fully controlled, with real-time nitrous oxide measurement both before and after SCR, enabling the catalyst volume to be varied with great precision. The optimal functioning of this system makes the Bilgin 263 a very environmentally-friendly boat that is suitable for all waters. “We are proud of how Bilgin Yachts realise these megayacht projects and of course of the fact that they choose MTU as their partner to power these huge projects. They were the first global MTU partner for SCR application on yacht segment and we are excited to achieve more first times with them” voices Ali Güzel, Managing Director of MTU Turkey. IMO Tier III, an exhaust gas emissions directive published by the International Maritime Organization, means that NOx emissions within certain areas (known as NECA: NOx Emission Control Areas) must be complied with. MTU is a product and solution brand of Rolls Royce.
