10MW direct-drive propulsion motor for commercial applications

Dr Russel Marvin
CEO
LC Drives
USA
Direct-drive propulsion motors have the advantage of simplicity and reliability over conventional geared offerings, but often cannot compete due to size and weight penalties. A new in-slot cooling approach is optimized for torque and efficiency and yields a motor small enough to make direct-drive propulsion attractive. This innovative approach to a liquid-cooled motor delivers higher torque density than equivalent superconducting solutions. A 10MW 130rpm base speed motor is discussed. To compare this design with other comparable designs, a performance metric – Mass Normalized Torque – is shown to be more relevant than typical metrics used for such comparisons.

Safe by design: the new standard in energy storage systems

Walter van der Pennen
Development manager
EST-Floattech
NETHERLANDS
Energy storage systems (ESS) are increasingly widely accepted as part of the ship's power system. The requirements and advantages differ depending on the type of ship. One requirement shared by all ships is the need for a safe ESS. Four factors influence the safety of an ESS: lack of control during (dis)-charge of the ESS, cell malfunctioning, cell heating by external heat source, short circuit. EST-Floattech will present its ‘Safe by Design’ safety philosophy, which takes care of these factors and resulted in a new safety standard for ESS.

Smart power and automation system for lightweight full-electric passenger vessel

Frode Skaar
Director
Westcon Power & Automation
NORWAY
Future of the Fjords will be the world’s first all-electric passenger catamaran built from carbon. The 40m-long vessel will take up to 400 tourists into the fjord between Flam and Gudvangen – a fjord that is on the Unesco's list of world heritage sites. During the 20-minute docking, an advanced charging station will charge the batteries with approximately 800kWh of energy. Low and zero emissions will be a requirement for ferries and smaller vessels. Short ferry crossings are particularly suitable for running on electric power, and the technology and expertise are available.

Multidomain methods to better understand and verify vessel power requirements

John Koopman
President
Propulsion Data Services Inc
USA
Vessels with scheduled routes are fairly simple to analyse with respect to power requirements. Many types of small to medium-size work vessels have what appear to be highly random power requirements and schedules, making realistic optimisation for electric and hybrid systems difficult. The presentation will discuss a process of acquiring operating data of a ubiquitous work boat for multiple months at a sub-second rate. Data includes all main systems, subsystems and navigational data. Multidomain analysis of the data provides insight into which electric or hybrid systems are most promising. As a verification of concept, promising systems are run against the original data.

The innovative Power Take-Off and Power Take-In – its intricacies

Dr Makhlouf Benatmane
Marine navy solutions leader
GE Power Conversion
UK
The shipping industry requires more-efficient, cleaner vessels, meeting stringent environment regulations and reducing carbon emissions. The development of technologies and selection of power and propulsion systems such as innovative Power Take-Off and Power Take-In to meet the ship’s operational profile and service load can result in achieving above goals, significant fuel savings and operational flexibility. The solution consists of motor-generator sets with propeller shafts connecting motor converter drives. The paper will describe PTO/PTI equipment, topology, modes of operation in each mode and how different modes are reversed, including results from real ship application.

Agile power management systems for marine vessels

Dr Chris Watts
Technology acquisition lead
Babcock DST
UK
An agile power management system for marine vessels is presented by a Babcock-led consortium with the University of Warwick (WMG) and Potenza Technology Ltd. The aim of this Innovate-UK-funded project is to take advances in automotive energy management techniques and develop a modular marine power management system, addressing the latest guidance and legislation for marine applications. The system employs novel power management algorithms developed using hardware-in-the-loop (HIL) modelling techniques. Capable of interfacing energy storage with multiple power sources and loads, the algorithms seek to maximise overall efficiency by improving prime-mover operational envelopes, hence reducing emissions and fuel consumption.

Hybrid energy and propulsion system for vessels in timetabled operation

Martin Einsiedler
Head of naval architecture and engineering
Shiptec AG
SWITZERLAND
In new designs or refits for inland waterways, the energy consumption of the propulsion and onboard systems is becoming the focus of attention. After ample measurements of multiple operational profiles, Shiptec AG determined that a new parallel hybrid system with battery buffer will be the optimal solution to reduce fuel consumption in timetabled operation by up to 25%. A dynamic management system controls the system in such a way that the distinct, transient processes can be smoothed out as much as possible. This allows the multiple diesel engines to work at their most efficient operating point or, at times, to be shut off.

Nanocrystalline cores for reduction of EMC in ship propulsion

Dr Wulf Günther
Manager, magnetic components
ACAL BFi
GERMANY
The presentation will discuss minimising RF disturbances in marine applications by utilising nanocrystalline cores around the cabling between inverters and electric motors. With nanocrystalline cores it is relatively easy to reduce the EMC parts in electric propulsion, without creating additional earth faults. RF disturbance may even cause damaged bearings, so avoidance is needed. Furthermore, earth fault currents can decrease the effects of cathodic protection.

Optimal energy management strategy for hybrid-electric marine vessels

Dr Truong Quang Dinh
Assistant professor
Warwick Manufacturing Group (WMG) - University of Warwick
UK
In the shipping industry, traditional vessels using diesel generators have been recognised as a major target for the hybridisation/electrification evolution to address rising fuel prices and the urgent need to reduce environmental pollution. This paper aims to develop an optimal energy management strategy (OEMS) for hybrid-electric vessels. This OEMS is built as a combination of a set of rules and an optimisation algorithm based on the machine states including power demands, grid and diesel generator performances, and battery states. The applicability of the proposed OEMS is then investigated through simulations with a number of test cases.

The inductive charger

Ingve Sorfonn
Chief expert, power conversion
Wärtsilä
NORWAY
The inductive charging system eliminates the cable connection between the vessel and shore, thereby securing and facilitating safe connections and disconnections. It also reduces maintenance. The system is capable of transferring more than a MW of electrical energy and increases the available charging time, thus optimising the energy transfer. The system is designed to maintain efficient power transfer at distances of 50cm between the two charging plates built into the side of the vessel and the quay. No other wireless charging system is as powerful, or capable of maintaining the transfer of energy at such a distance.

Standardisation of hybrid systems for high-performance applications

Dr Gerhard Filip
Senior manager
MTU Friedrichshafen GmbH
GERMANY
During the last decade MTU Friedrichshafen has gained valuable experience with various hybrid systems for marine and railway applications. An overview of the actual operation experience will be presented. These projects have been based on individual approaches and therefore caused significant one-time effort for the adaptation of the automation and protection systems. To achieve an attractive total cost of ownership, MTU Friedrichshafen is standardising such systems based on a portfolio of hybrid components. A standardised modular automation system is key to combine the advantages of series production with the requirements of various applications in commercial as well as recreational vessels.

Safe application of DC grids and hybrid battery systems

Helge Vandel Jensen
Development manager
Danfoss Drives AS
DENMARK
DC grid systems on board electric and hybrid vessels offer clear benefits in terms of reduced conversion losses, fewer problems with harmonic distortion and easy integration of battery energy storage systems to shave power peaks and allow downsizing of diesel and LNG-powered engines. This presentation will discuss the challenges with large DC short-circuit currents and potential methods to overcome these challenges.

Batteries integration on diesel-electric ships through the propulsion converters’ DC-Link

Iñigo Atutxa
Technical Director - Industry and Marine Drives
Ingeteam
SPAIN
The use of batteries in electrically propelled vessels is awakening great interest. Batteries, usually integrated through power electronics converters, permit the vessel operation in fully electric mode and provide peak shaving and spinning reserve services in hybrid mode. The energy efficiency, emissions and life of the Gensets can be then significantly improved. Different ways of integrating batteries in vessel power systems are first reviewed. The advantages of integrating them through the propulsion converters’ DC-Link are highlighted. Such aspects as the better performance of the peak shaving services and the possibility of emulating virtual Gensets are presented & discussed in detail.

Testing power electronics control units

Matthias Deter
Group manager engineering
dSPACE GmbH
GERMANY
Hybrid powertrains are a key technology with regard to energy saving and environmental friendliness of modern ships. Highest efficiency requires controlling the energy flow in all involved system components. For this purpose, the specific ECUs are networked and superimposed management systems are used. Extensive testing of these complex structures is laborious. Hardware-in-the-loop (HIL) simulation enables testing at the functional, component and integration level. The solutions for HIL simulation are derived from the physical properties and require specific approaches. Depending on the target system, differential equation- and topology-based plant models can be embedded on real-time processors and FPGAs.

Integrating Maritime Power System Design and Testing Using Controller Hardware-in-the-Loop

Matt Baker
Director for Microgrids and Critical Power
Typhoon HIL Inc.

Hybridisation of research vessel propulsion

Marko Loisa
Business manager
Protacon Technologies
FINLAND
Aranda is an ice-strengthened research vessel suitable for multidisciplinary marine research all year round. The shipowner, the Finnish Environment Institute (SYKE), wanted to replace the vessel’s diesel propulsion system with a hybrid drive. Since the renovation, the vessel can be driven by electricity produced by a generator connected to a diesel engine and electricity received from a powerful battery unit. By using batteries to reduce the use of diesel engines, it is possible to considerably reduce sulphur emissions. A hybrid solution also reduces noise transmitted to sea. In turn, noise reduction facilitates research of marine organisms.

Full-electric production pleasure boat

Dr Japec Jakopin
CEO
J&J Design
SLOVENIA
Dr Christoph Ballin
Co-founder and CEO
Torqeedo GmbH
GERMANY
J&J Design, with its decade of experience in hybrid-powered pleasure boating, joined forces with the world leader in electric propulsion, Torqeedo. The result is a new design of a full-electric 30-footer engineered for high-volume production. The design of the boat (naval architecture, general arrangement, programme) was fully integrated with engineering of the propulsion system, energy storage and management for efficiency and value optimisation. The new double-speed hybrid hull design couples low-drag displacement speed and fast planing speed, both achieved by high-voltage electric outboard power. The propulsion, energy storage, charging and management systems come from the automotive world, and give unbeatable value and reliability. A range extender provides longer range and propulsion redundancy. A range of standard AC-powered home appliances, air-conditioning, etc. enable home comforts and convenience on board. A newly developed energy management system integrates the propulsion and home comforts energy needs, replenishment and control. The new boat is improving the boating experience while making it more affordable. This creates a firm base to increase the boating population and make boating more sustainable and green at the same time.
