Open Simulation Platform for the design of maritime hybrid systems

Kristine Bruun Ludvigsen
Principal engineer
Dr Kevin Koosup Yum
Research scientist
Sintef Ocean
The Open Simulation Platform will create the foundation for an ecosystem where the maritime industry can perform co-simulation and share simulation models in an efficient and secure way to facilitate the building of digital twin systems and vessels. Such ecosystems will be used to solve challenges with designing, building, integrating, commissioning and operating complex, integrated systems. One of the use cases in the joint industry project that will end in June 2020 demonstrates the use of this platform for the design of a hybrid ferry. This session will include a presentation of the OSP with a focus on simulation tools for hybrid system design.

Modeling and simulation of multiple-power-source hybrid vessels

Rodolfo Puraca
Universidade de São Paulo
We develop numerical models and perform simulations of hybrid propulsion systems for vessels containing dual-fuel combustion engines, electric motors, batteries and fuel cell systems. The hybrid power system models are integrated into the maritime mission simulator developed at the University of São Paulo. The system can be run in real time, with a complete interface with a pilot, or automatically, with pre-defined mission, weather and sea conditions, and pilot inputs. We validate the model with data from existing real systems, and propose and test optimized solutions for hybrid power architecture and supervisory control.

New azimuth thruster system with cooperating dual motor

Whang Cho
Full professor
Kwangwoon University
A new technology in azimuth thruster systems powered by dual motor is proposed. The technology demonstrates the practicality and feasibility of employing two motors with the same capacity in cooperatively driving both the propeller and pod, simultaneously. The practicality of the technology is addressed, focusing on energy efficiency, system reliability and fault tolerance in comparison with conventional azimuth thruster systems like Z-drive, L-drive and podded systems. The feasibility of this new technology is verified through the point of view of extensive simulations from two-inputs and two-outputs control systems.

Simplifying motor testing and characterization

René Bastiaanssen
Business development manager
HBM Test and Measurement
During this session we will go into the question of how to simplify advanced testing tasks related to electric/hybrid propulsion systems. Beyond pure power and efficiency measurements, we will discuss analysis topics like NVH, DQ0, space vector, torque ripple, back EMF, dynamic power measurements and correlating vibration and electric drive test data. Furthermore, we will discuss how to handle the testing of drives with voltages >1,000V, more than three phases or multiple motors/generators (a common sight in the maritime industry).

Energy storage

How batteries are unlocking the future of marine electrification

Allan Grant
Executive vice president
Short-range vessels such as ferries and tugboats are among the largest greenhouse gas contributors in the transportation system. The global marine transportation industry needs to undergo a fundamental change in order to increase efficiency, reduce fuel and maintenance costs, and lower emissions. Conventional lithium-ion storage technologies just won’t cut it – that’s where advancements in battery technology and energy storage systems come in. The presentation will explore the current state of marine electrification, what is lacking, and how innovations in battery technology are paving the way to a more sustainable future for the marine industry and beyond.

Decentralized ship energy system with fuel cells and energy storage

Lukas Kistner
Institute for Electrical Energy Systems, Leibniz Universität Hannover
Ship energy systems with higher efficiency and fewer pollutant emissions are vital to meet upcoming stricter climate protection targets. Therefore, we focus on a decentralized approach for the electric power supply, containing modular fuel cells (SOFC) with LNG reformer plants and hybrid energy storage composed of Li-ion batteries and supercapacitors. The economically optimal dimensioning and positioning of the aggregates is conducted and compared regarding three different levels of detail and presented for a real-life case study, taking into account a highly dynamic energy demand while fulfilling voltage quality requirements and smooth operation of the fuel cells.

Fuel cell solutions for marine application

Jesper Themsen
President and CEO
Ballard Power Systems
With future regulations on the horizon, port authorities and ship owners/operators are looking at alternative propulsion to reduce emissions. Fuel cell technology provides an attractive zero-emission solution to generate electricity on board using hydrogen as a fuel. Fuel cell systems are scalable from 100kW to MW, providing high-efficiency, quiet power generation. Several pilot projects are on the way to demonstrate the marine application of this proven technology. This presentation will review the fuel cell value proposition for marine applications, product design considerations, Ballard marine projects as well as opportunities and challenges for the adoption of fuel cells.

Battery fire safety for lithium-ion battery systems

Sverre Eriksen
Senior principal engineer
The presentation will address the fire and explosion safety of battery installations on board ships. Fire integrity, fire detection and fire extinguishing in addition to explosion protection and ventilation will be covered. The presentation will reference specific requirements given in the DNV GL class rules for electrical energy storage installations.

Hybrid propulsion of inland waterway passenger ships – class approach

Marek Narewski
Technical specialist
Polish Register of Shipping
Hybrid propulsion of ships requires the use of alternative fuels. Relevant ship systems must be designed to guarantee the expected ship safety level. The key issues are alternative fuel storage and fuel supply for ship propulsion. The use of compressed hydrogen or methane demands complex design analysis and is critical from a safety point of view. The results of a short engineering analysis are presented with some guidance on ship design based on a shallow-water inland waterways passenger ship project that required the introduction of novel and safe solutions in the ship design. The safety approach priority is crucial in the certification process conducted by class societies.

European Interreg 2 Seas project – Implementation of Ship HYbridization (ISHY)

Graeme Hawksley
Managing director
Hybrid Marine Ltd
This ambitious €16m project has 15 partners consisting of universities and companies active in hybridization. The aim is to develop tools and business models for the implementation of hybrid and hydrogen fuel cell technologies in vessels and ports. Four vessels will be fitted with hybrid/hydrogen technologies and an H2-bunkering station for vessels will be built at the port of Ostend. Now at the midway point, in the summer of 2020, this presentation will provide an update on progress so far. Challenges encountered will be presented together with a discussion on the next stages of the project.

Safe and effective application of ammonia as a marine fuel

Niels de Vries
Lead naval architect
C‑Job Naval Architects
Niels de Vries, lead naval architect at C-Job Naval Architects, won the Maritime Designer Award 2019 for his research on the safe and effective application of ammonia as a marine fuel. His research showed that in the long term the Solid Oxide Fuel Cell is the best option as it is the most efficient, but currently has practical challenges which in time may be overcome. However, a three step plan could see step one as, ammonia and marine diesel in an (Compression Ignition) Internal Combustion Engine (ICE). The second stage would be an ICE using ammonia hydrogen mixtures and then the third and final stage an SOFC using ammonia. In this presentation Niels will outline the essential details of how to achieve the ultimate goal.

Panel Discussion

Will hydrogen become a must-have marine fuel?

Hydrogen-energy technologies – maturing thanks to road transportation applications – have reached a first level of cost competitiveness, qualifying them for demonstration projects in waterborne applications. If their intrinsic limitations (e.g. energy density) cast doubts on their ability to constitute a radical alternative to existing fuels, the question of the precise role they could play in the sector is at stake. This role is also likely to be influenced by local characteristics and tax regulations. Through the experience of MARANDA and Flagships, this discussion will offer a few insights to guide those considering hydrogen and fuel cells for investment.
