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?

Development of a hybrid vessel simulator
Dr Bruno Carmo Assistant professor University of São Paulo BRAZIL
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 Developer Siemens PLM FRANCE
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 AUSTRIA
Increased system complexity of hybrid applications demands new development approaches regarding the optimization of maritime systems and the classification process for vessels. Advanced co-simulation of entire vessels supports component specification for energy and propulsion systems, the optimization of operating strategies, and facilitates lifecycle investigations and economic analysis. This presentation demonstrates the multi-domain system simulation for a multipurpose vessel when evaluating the fuel saving potential of a proposed energy storage system, and specifying the battery cell type 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 & chair department of mechanical engineering University of Victoria CANADA
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.

Power measurement on complex hybrid/electric drive systems
Jyri Niinistö Engineer HBM FINLAND
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 SPAIN
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 limited and fast and efficient control of the output current must be enabled 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 UK
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.

Fully integrated power system in a compact plug-and-play unit
Matti Lehti Senior system manager, electrical systems ABB Marine & Ports 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 meet 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.
MBSE – ready and required for hybrid electric marine applications
Matt Baker Director microgrids and critical power Typhoon HIL USA
Model-based systems engineering has existed in many forms for years; in some cases, like 3D CADCAM for mechanical design, it is the industry standard. However, a true modeling and simulation capability that can handle the fidelity/time step requirements of systems incorporating power electronics and controls has not existed until now. Controller-hardware-in-the-loop technology combined with FPGA-based computing allows the design, development, commissioning and efficient operation of integrated power systems aboard hybrid vessels. Equally importantly, this technology enables the digital twin concept, artificial intelligence and machine learning.
