Electrification of boats - Dewesoft measurement units

Rupert Schwarz
Application engineer power and e-mobility
Dewesoft GmbH
AUSTRIA
For precise efficiency and energy consumption measurements of hybrid ships you need a combustion analyzer, a power analyzer and dataloggers for mechanical parameters. We invented a ruggedized power analyzer that combines the functionality of all these systems for testbeds and also for real-drive tests. It can measure any kinds of signals (electrical, mechanical, digital, video, etc.) and the powerful software allows power and combustion analysis at the same time, which is unique in the market. The analyzers can be synchronized to place them close to the point of measurement, to achieve a reduction in cable length and measurement errors.

Battery emulation for testing hybrid and electric marine powertrains

Lex van Huuksloot
T&M consultant
TTMS BV
NETHERLANDS
The use of batteries and accumulators to store energy is increasing enormously. For developers and test engineers in power conversion, testing the power electronics needed for power conversion is quite a challenge. The use of a battery emulator that behaves exactly like a real battery pack gives optimal flexibility. With a well-programmed emulator, the battery voltage depends, just like the real battery, on the state of charge, the charge and discharge speed, and the internal charge and discharge resistance. In addition, a battery emulator offers a high degree of flexibility due to its programmability during the execution of the various test phases in the R&D lab and during production. Last but not least, you save space and safety is more manageable.

Beyond the lifecycle cost analysis – technologies on the horizon

Will Ayers, PE
Chief electrical engineer
Elliott Bay Design Group
USA
Vessel operators around the world are considering hybrid propulsion systems given the many proven solutions in the marketplace. In this presentation, we will highlight feasibility and lifecycle cost analyses that helped Washington State Ferries move forward with electrification. The lifecycle cost analysis assumes that technology is static over the long life of the vessel. However, expected improvements in technology will reduce the lifecycle costs even further. Improvements in the near term include the current lithium-ion technology as well as solid-state and silicon anodes. Game-changing technologies on the horizon include lithium-sulfur, lithium-metal and lithium-air.

Fully integrated power system in a plug-and-play compact

Matti Lehti
Senior systems manager, electrical systems
ABB
FINLAND
Hybrid and fully electric power systems are increasingly popular in smaller coastal and river vessels. With limited space available on board, the power system needs to be highly compact, robust and reliable. To answer these needs, ABB has developed a fully integrated power system unit packed into a compact enclosure housing, consisting of drives for power generation, shore connection, battery energy storage, propulsion and other motor drives, and AC network supply, as well as an integrated control system. The self-service unit can sit freely in the engine room, and the DC distribution allows fuel cells or other energy sources to be added later on.

Precise load measurement for the optimization of ship propulsion systems

Guy Beaho
Manager business development
HBM
GERMANY
The optimization of ships' engines on the basis of the highly precise and reliable T40MAR torque sensor from HBM enables considerable fuel savings and is also in line with the constantly increasing demands of international regulations. T40MAR is HBM’s torque flange that was specially developed and certified for use in ship propulsion systems. Its measurement accuracy enables the calculation of load signals with at least 10 times higher accuracy than that required by the shipping industry’s current environmental regulations.

14:15

Smart hybrid microgrids of the future

Danny Francissen
Application specialist
Bosch Rexroth
NETHERLANDS
Offshore rigs and vessels can be seen as remote microgrids. By making use of smart hybrid- or full-electric energy management solutions, efficiency can be increased while operational costs and environmental impact can be significantly reduced. This presentation focuses on Bosch Rexroth solutions and the following main topics: automatic synchronization with generator(s); providing a DC load bus next to an AC load bus, thus creating a local DC grid; reducing peak power demands from grid (peak shaving); and providing backup power in case of main power grid failure.

IConIC – the pre-emptive fault recognition system

Dr David Garrity
Chief technology officer
STS Defence
UK
Globally there is a big drive to introduce more automation and autonomy in marine and maritime, particularly through the exploitation of recent advancements in the application of artificial intelligence (AI) to solve challenging problems. Although much of the focus has been on solving automation/autonomy challenges for navigation systems, there has been limited thought about how to approach the engineering spaces, particularly the main propulsion and auxiliary power units. In the work presented here, an AI-enabled condition monitoring system developed over the past five years for all scales of marine diesel units, and rotating plant machinery more generally, is showcased.

14:45

Why are hybrid installations in yachting so challenging?

Tobias Kohl
Senior manager yacht applications - Marine Application Center
MTU Friedrichshafen GmbH
GERMANY
Electrification has become one of the most discussed technology topics in the yachting industry. Performance and comfort are identified as the main drivers, and the optimization potential of the conventional diesel engines is a nice takeaway. On the other hand, sufficient availability of the necessary electrical energy for propulsion or electrical consumers on board, such as air-conditioners or the galley, requires additional volume-consuming technical equipment for electrical energy generation, distribution and storage. As soon as accommodation space on board is affected by larger gensets or a high number of batteries, the interest of potential customers in hybrid installations evaporates quickly.
