Opening Keynote Session

The Elemed action: electrification as the key to sea mobility
Panayiotis Mitrou, technology and innovation manager, marine and offshore, Lloyd's Register, GREECE
Smart grids integrating renewable electricity create an excellent environment for hybrid ships and battery applications. Elemed action paves the way to a zero-emission marine future, minimising impact to ports with the use of cold-ironing and densifying short-sea connections with electric propulsion. Renewable potential and edge technology uptake build efficient synergies, vital to the economic growth of eastern Mediterranean ports and sustainable short interconnections in the Greek archipelago. This presentation features a vessel concept optimisation and the development of an effective framework as key steps to the introduction of electricity as an alternative fuel in the marine sector.

Advanced hybrid systems and new integration challenges
Oliver Simmonds, lead engineer, GE Power Conversion, UK
In recent years there has been a marked shift towards hybrid propulsion systems. Although the main reasons for adopting hybrids have been for efficiency and through-life fuel savings, they also offer increased flexibility for varying operating profiles. These hybrids combine a diesel engine with an induction motor fed by an active-front-end variable-speed electric drive, which can operate as both a motor (power take-in) and a generator (power take-off). These systems require the correct integration to fully maximise the potential. This presentation explores recent experience on the UK MARS tankers and the Norwegian Logistics & Support Vessel.

Flywheel energy stores from directed energy weapons to grid management
Sean Worrall, business development manager, GKN Hybrid Power, UK
This novel technology cut its teeth in top-flight endurance racing, helping to power Audi’s R18 e-Tron Quattro to four successive Le Mans 24-hour race podiums. The GKN Hybrid Power flywheel is an electric flywheel, storing energy mechanically in a high-speed carbon rotor and transferring power directly to and from the DC bus. By combining multiple flywheels in a single module, very high energies and powers can be safely stored and provided. The technology was developed with the UK MOD as the energy store for an experimental DEW system. Fire safety and long life make it an ideal ship grid management tool.

Designing and Developing Hybrid Systems

A virtual power box approach to a hybrid system
Peter Rogers, director, Wärtsilä, GERMANY
Wärtsilä has developed a virtual power box consisting of the engine, energy storage, power electronics and energy management system, with all components optimised to work together. The system, Wärtsilä-HY, has the advantage in that the engine control system plus the energy management system does much more than just control the flow of fuel. The new feature is that the management of energy from engine and batteries leads to an optimised aggregated energy flow. Based on advanced algorithms, this allows selection between different operational modes, optimising efficiency, emissions or vessel performance. In addition, the pre-engineering and testing allow for easy installation and performance predictability throughout its lifecycle. This presentation will describe the system in detail.

Challenges and solutions for electrification/hybridisation in large engine applications
Wilhelm Mueller, vice president large engines, engineering and technology powertrain systems, AVL List GmbH, AUSTRIA
Electrification and hybridisation are established in automotive. The use of hybrid and electric drives has started in large engine applications. The challenges of E&H in the large engine fields are described and solutions presented, including simulation as a pre-calculation tool to forecast the benefits, to optimise the layout of the components and to calculate the ROI. AVL’s successful experience of automotive hybrid and electric designs and the knowledge transfer to the large engine business field is shown. An important focus of the presentation is simulation in the virtual design phase and the results of the later hardware design. The session will finish with an outlook to the future.

Optimisation of electric drive systems for electric and hybrid vessels
Helge Vandel Jensen, business development manager, Danfoss Drives AS, DENMARK
Drives are essential components in electric and hybrid vessels. However, the electric propulsion topology must be optimised for each type of vessel to ensure low cost of ownership and reliable operation. Key words: energy efficiency, battery charging profile, AC vs. DC grid, shaft generators, micro-grids, shore power connections, common mode voltage reduction, functional safety and reliability. The presentation will show experience from actual cases.

Electrically powered ferry propulsion power estimation in underpowered operational conditions
Marek Narewski, technical specialist, Polish Register of Shipping, POLAND
In 2014 the authors performed a short engineering analysis of small electrically propelled inland passenger ships. Operational experience gave evidence that in certain weather conditions the phenomenon of added aerodynamic resistance may have serious influence on ship speed and manoeuvrability. Existing regulations do not provide any requirements or guidelines on prediction of air or hydrodynamic resistance or propulsion power in the design process. The case is important when electrical or hybrid propulsion is the prime mover. The presentation describes the results of the engineering analysis of ship design to verify the influence of aerodynamic resistance on propulsion system power selection and performance.

The author presents the novel idea of integrating a tidal turbine system with barge-based systems, which enables easy deployment in the high tidal energy resource sites. This creates the possibility of harnessing ocean energy to explore cost-efficient and effective energy storage solutions towards providing the infrastructure for electrification of boats and other maritime-related power needs.

The good, the bad and the unreliable: power quality economy
Benjamin Sternkopf, energy storage engineer, Stable Shore Power, GERMANY
The integration of smart grid flexibilisation technologies is dramatically changing the paradigm for electrical grid operation in onshore and marine applications. Instead of the one-size-fits-all approach of providing equal power quality and reliability to all grid participants, the quality of service is determined by the user requirement. By this method, ultra-high-reliability requirements can be met while reducing the overall cost of energy. This presentation will show how these requirements are categorised, how they are met and how this strategy improves the economy of large- and small-scale electrical grids.

Using AIS to dimension shore power infrastructure – the ReCharge project
