The future of shipping

Kolbjørn Berge
Project manager
Norwegian Maritime Authority
Shipping needs to change; it has to change more in the next decade than it has done in the last three decades. No stone should be left unturned to find the best solutions to achieve sustainable shipping. Stricter environmental requirements both from regulatory bodies and customers will shape shipping in the future. Why should shipping change and what will it be like in the future? How can the authorities facilitate this change?


A zero-emissions shipping world by 2040

Prasanna Colluru
Director corporate strategy
Future Proof Shipping
Future Proof Shipping envisions a zero-emissions shipping world by 2040. We’d like to share our thoughts on the challenges facing the maritime industry and our views on what needs to change to usher in a zero-emissions shipping world in the timeline we envision. We realize this target is ambitious, but we believe that mapping out potential ways to achieve it is the first step toward actually getting there.


The battery-powered fleet – a market overview

Sondre Henningsgard
Managing director
Maritime Battery Forum
Marine batteries are seeing widespread adoption. But what is the real extent of this adoption? Few have seen the full picture. What does the uptake look like? How will it develop? In this presentation, Maritime Battery Forum provides an extensive briefing and the latest data on the uptake of batteries in the commercial maritime fleet, and some thoughts on the potential.


Panel Q&A

Simulation and Modelling
11:00 - 13:00


Testing results of a compact propulsion motor for commercial applications

Dr Russel Marvin
LC Drives
LC Drives has completed testing of its in-slot cooled electric motor that is half the size of the next best in the world. This commercial product offers a significant space advantage compared with conventional high-performance permanent-magnet motors. This comparison will be shown, as well as how this technology scales to larger sizes required for direct-drive propulsion systems on large ships. Actual testing results will be shown compared with predicted values.


Development of a hybrid vessel simulator

Dr Bruno Carmo
Assistant professor
University of São Paulo
We integrated electric and energetic models of hybrid power systems in the maritime mission simulator developed at the University of São Paulo. The model takes the dynamics of the power system into consideration in the simulation and can provide the efficiency, fuel consumption and emissions for a given mission. 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. This simulator can be used as a testbed for different power system components and configurations, and as a valuable training and validation tool.


Offshore supply vessels: a comparison of propulsion system architectures

Romain Nicolas
Siemens PLM
Offshore supply vessels are the workhorses of the offshore industry, carrying equipment and personnel to offshore structures as well as performing other duties such as firefighting. The load profile of each OSV allows the electrical and drive power generation to be adapted to optimize efficiency for its specific usage. In this work, fuel consumption and NOx emissions of an OSV with four possible propulsion architectures with varying degrees of electrification are compared using system simulation. Constant and rapidly varying stationary electrical and speed profiles are used to evaluate the architectures under ideal conditions before they are compared using six-day industrial load scenarios.


System simulation as a beneficial methodology for optimizing hybrid vessels

Robert Strasser
Lead engineer
AVL List GmbH
Increased system complexity of hybrid applications demands new development approaches regarding optimization of maritime systems as well as for the classification process for vessels. Advanced co-simulation of entire vessels supports the component specification of energy and propulsion systems and the optimization of operating strategies, and facilitates lifecycle investigations and economic analysis. The multi-domain system simulation for a multi-purpose vessel is demonstrated for the evaluation of fuel-saving potential under consideration of an energy-storage system, and for the specification of the cell type of the batteries for given power requirements, by applying consistent plant modeling with an open and integrative co-simulation platform.


Study on different types of vessel drag and thrust models for integrated hybrid-electric marine propulsion system modeling tools

Prof Zuomin Dong
Professor and chair Department of Mechanical Engineering
University of Victoria
This research compares four different types of vessel hull drag and propulsor thrust models used today and recently introduced in our work, including full-scale CFD simulations, reduced-order hydrodynamic models, low-order hydrodynamic models and generic parametric mathematical models. The different fidelity levels of these models, validated using vessel sea-trial data, and their diverse computation requirements are studied through case studies on the integrated modeling and optimization of hybrid-electric marine propulsion systems, as well as on the prediction and control of ship induced cavitation noise.


Panel Q&A

Power Electronics and Control
14:00 - 15:40


Power measurement on complex hybrid/electric drive systems

Klaus Lang
Development manager
Power measurements are challenging when it comes to complex hybrid or electric systems, consisting of various different components like multiple e-machines with three or more phases, gearboxes, inverters, batteries, and eventually a combustion engine. New approaches are needed to address these measurements, and at the same time other important signals like temperatures and vibrations need to be acquired and stored as well. The high voltages used in maritime e-drives are another challenge to be addressed.


Short-circuit fault current control in static frequency converters for BESS

Ivan Martinez-Ramos
Product development, regulation R&D manager
Ingeteam Power Technology, SA
Certification classes require that to be considered a primary generator and to reduce the number of DGs, a static frequency converter (SFC) must provide full discrimination for protection. Due to its semiconductors, an SFC is more limited and it is necessary to enable fast and efficient control of the output current to avoid tripping the protections of the converter. The purpose of this presentation is to analyze the different scenarios in which an SFC will provide short-circuit current. The response of the system to three-phase, two-phase and earth-phase short circuits will be analyzed.


Advanced battery-based energy storage, with an emphasis on electrical power systems

Dr Makhlouf Benatmane
Marine navy solutions leader
GE Power Conversion
This paper will present an overview of energy storage systems and describe current capabilities in terms of kW and kWh, and considerations when integrating energy storage into marine vessels. Considerations will include types of applications, from high power, short duration to sustained power, long duration, and will describe the analysis required to optimize the energy storage asset and ensure adequate power system performance in terms of operational and common mode considerations when using pulse-width modulation (PWM) converters connected to battery or ultra-capacitor-based energy storage systems. Common mode effects will also be considered.


Additional presentation by Siemens Marine will be confirmed shortly.


Panel Q&A

Hydrogen Power Case Studies
16:10 - 17:30


Experiences from FCH JU project MARANDA for maritime fuel cell and hydrogen storage system design and operation

Dr Jari Ihonen
Principal scientist
Laurence Grand-Clément
In the MARANDA project, an emission-free, hydrogen-fueled, PEMFC-based hybrid powertrain system and 80kg hydrogen storage unit were developed for marine applications and validated both in test benches and on board the research vessel Aranda. This 165kW (2 x 82.5kW AC) fuel cell powertrain (hybridized with a battery) will provide power to the vessel's electrical equipment as well as the dynamic positioning during measurements, free from vibration, noise and air pollution. This presentation outlines the main issues in the system design and first experimental experiences, as well as the development needs of regulations, codes and standards (RCS) for maritime use of hydrogen fuel cells. In addition, the initial go-to-market strategy for hydrogen fuel cells in maritime use is presented.


Hydrogen-powered inland cargo vessel

Fokke van der Veen
Operations director
Future Proof Shipping BV
Future Proof Shipping BV is developing a zero-emissions hydrogen-powered inland vessel, which will carry container cargo between the Netherlands and Belgium. We will retrofit an existing 110m vessel with fuels cells and batteries after removing the internal combustion engine. Through this, we want to validate the technical and commercial feasibility of retrofitting a zero-emissions propulsion system on board an inland vessel.


Water-Go-Round: North America's first commercial hydrogen fuel cell vessel

Dr Joseph Pratt
Golden Gate Zero Emission Marine
When it is launched in fall 2019, the Water-Go-Round will be the first commercial, USCG-inspected hydrogen fuel cell electric vessel in North America. The Water-Go-Round concept was started over four years ago with the first SF-BREEZE study. This presentation will describe the path to the Water-Go-Round and give unique insights into the vessel's design and up-to-date construction progress.
