Maritime port of the future – energy and power management in the ship-shore interface

Ricardo Batista
Senior naval architect
European Maritime Safety Agency
Portugal
In a context where decarbonization, energy efficiency, digitization and innovation are transformational drivers in shipping, maritime ports face increasing pressure for adaptation. In this multi-dimensional paradigm, electrification is an important construction block at the infrastructure level. With several factors affecting the design of intra-port electrical grids, the role of energy and power management assumes central relevance for energy quality, security and port services resilience. Shoreside electricity, including Onshore Power Supply (OPS) or Battery Charging, is among the port energy services that are expected to grow in the next decade. How can the wider port infrastructure develop to face the challenges of increasing energy and power demand from shoreside electricity? How can smart-grid framework design facilitate opportunities for an integrated port ecosystem with a focus on the ship-shore interface? What will be the major challenges for the development of shoreside electricity for a variety of different ship types and operating profiles? How to fight the risk of low utilization periods? These, among other questions, are important aspects to address for the implementation of integrated ship-shore interfaces in the maritime ports of the future.

Plug-in shore power delivers sustainability from grid to propeller

Jesse Makkonen
Product manager for automatic chargers and cable management systems
ABB Marine & Ports
Finland
Ship operators are under pressure to lower emissions in port, to improve local air quality. This can be achieved with shore connection. Going one step further, combining shore connection with energy storage systems opens the opportunity to create a zero-emission cycle for the vessel. Energy storage can even be installed on shore for quay-side peak shaving, to avoid overloading the local electrical grid and charge at cheaper rates.

Interoperable charging infrastructure

Jacques Borremans
Director Asia
CharIN EV

This paper presents the CO2 emission reductions obtained by using different hybrid solutions on the power generation system of a platform supply vessel (PSV). The proposed solutions consist of auxiliary generators, three types of batteries and a proton exchange membrane fuel cell (PEMFC). The selection of alternative power system configurations is made considering the possibility of retrofitting an existing PSV. The Homer software is used to perform simulations and quantify the CO2 emitted by each configuration. The highest reduction in CO2 emissions is 10.21%.

Highly redundant parallel hybrid propulsion for marine applications

Thomas Vetter
CTO
Aradex AG
Germany
The propulsion drives of ships are of great importance for the safety of the ship. Therefore, the propulsion drives must be highly available. Depending on the exact application, intensive validation of changes in the propulsion of a ship is necessary. Besides pure electric propulsion, Aradex presents a special version of parallel hybrid propulsion with extremely high redundancy. To reach the highest redundancy we use AC induction motors, which have no impact on the diesel-driven drivetrain in case of any defects. A special version even needs no additional gearbox.

Is water cooling the weakest link in your solution?

Heikki Mustonen
CEO
Adwatec Oy
Finland
Marine systems use liquid or water cooling for space reasons. Cooling in general and water cooling specifically pose risks for the energy system: lack of cooling may lead to partial or total failure of the vessel. There are multiple ways to reduce or completely eliminate the risk. The cooling system may be built to last, the number of connection points may be minimized and, most importantly, a proven product solution made of standard modules may be used. This presentation introduces the different risk-reducing means to ensure reliability and usability even in the toughest conditions.

Battery sizing for post-worst-case failure operations

Ben Hukins
Team lead marine operations and dynamic positioning
DNV
UK
Various marine operations require the vessel to be able to safely cease the current operation or maintain a certain minimum operational requirement following any single failure; for example, dynamic positioning and redundant propulsion applications. Designs often rely on a single battery bank being available post worst-case failure to meet this demand. However, different classification societies and different classification notations place different demands on the requirements and capacity of the battery. An appreciation of what the battery needs to be sized for and the classification society requirements can have a significant impact on the capacity of the battery required.

System design for hydrogen-powered inland vessels

Milinko Godjevac
Senior integration advisor
Future Proof Shipping
Netherlands
Future Proof Shipping (FPS) chose to retrofit its Maas inland vessel to full zero-emission technology by replacing the existing internal combustion engines with hydrogen fuel cell technology. Proper sizing of the fuel cells and hydrogen storage is crucial for the project. We measured the power profile of the vessel for several months to ensure that we have a deep understanding of the operations. We will share results from the measurements and present the basis for safety design and sizing of the fuel cells and onboard hydrogen storage.

Battery aging performance prediction based on different vessel profiles

Shivdeep Gaagat
Business developer - system simulation
Siemens Digital Industries Software
Germany
Shipowners are often concerned about battery durability and performance over time, especially since every vessel has different operating profiles that severely affect the battery aging and performance characteristics. In this presentation we propose to build a Li-ion battery model based on an LFP cell supplier that can predict the capacity loss depending on the operational calendar and cyclic aging. Such a model can be used to define a warranty strategy and allow predictive maintenance for every single pack. This would give the shipowner clarity on the reliability of the vessel while reducing costly unplanned downtimes for troubleshooting and maintenance.

Utilising DC Switchboards in combination with hydrogen cell and batteries for a smoother transition to electrified systems

Johan Stavik
Sales manager
Vard Electro
Norway
Increasing interest in alternative energy and the demand for reduced emissions have posed challenges for us to combine various energy sources for optimal vessel operations. To achieve the optimal energy setup with variable speed and load, the alternative can be to use DC distribution on a small or larger scale, from microgrids to complete main grids. To prepare vessels for today’s and future regulations and technology, it is necessary to consider everything from flywheels, solar panels, fuel cells and batteries to LNG engines and conventional engines running together with individual load control to achieve optimal load and emissions.

This presentation will cover various aspects of software, analytics and methods which can be adopted for electric and hybrid vessel performance management and which feature advanced analytics to detect off-standard behaviour and enable greater operational performance and energy efficiency. These analytical tools offer real-time feedback on operational Key Performance Indicators (KPIs) providing a view on the health of the critical assets and provide early warnings of developing issues with advisories for timely and targeted intervention. The tools outlined in the presentation leverage GE’s expertise in digital solutions, deep domain experience and understanding, across the marine, energy, process industry and infrastructure sectors. Apart from the overall efficiency gains which can be unlocked, the predictive capabilities for equipment/system also enable predictive maintenance, reduce unplanned downtime and increase vessel reliability and availability.

Modeling, simulation and control of hybrid power systems for vessels

Crisley de Souza Peixoto
Researcher
Universidade de São Paulo
Brazil
This presentation will describe research results from hybrid power system simulation for vessels. It will discuss the challenges and the adopted methodology to develop a dynamical simulator to predict the performance of powertrains, and will propose control strategies to improve the hybrid solutions. The simulator can be integrated with maritime mission simulators that provide vessel physics information and allow simulation under different environmental conditions. Models of system components such as gensets, lithium-ion batteries, fuel cells and electric motors, as well as primary control and an optimal energy management strategy, will be described. Finally, a case study will be discussed.

Simplifying motor testing and characterization

René Bastiaanssen
Business development manager
HBK
Netherlands
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 including 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).

Fully automatic testing of electric drives

Philipp Scherb
Product manager
Atesteo GmbH & Co KG
Germany
A vessel’s drivetrain can be tested with customized cycles; the battery can be automatically charged with more than 200kW. Data monitoring of the battery during the charge and discharge periods gives insights into all details and ensures a high degree of safety during prototype testing. The durability of the electric drive and its battery is proved in these kinds of tests as well. This presentation will describe a vehicle-related project for 24/7 endurance testing of electric drivetrain prototypes, including their traction batteries.

Theatre One Wabtec Stemmann Technik Workshop: Shore power – what you get is what you see

Shore power became a standard instrument for going green in the past. While general expectations led to the development of standards including norm IEC 80005, harbor expectations of solutions for cable management stayed very close to the local requirements for its infrastructure. There is now a huge demand for flexibility in cable handling to close this gap. The presentation shows recent solutions for various types of vessels and different local needs.

Theatre Two Panel discussion on charging standards

CharIN is the organization that represents the ISO 15115 charging communication protocol, the CCS and MCS charging plug. Under the CharIN umbrella, cross-industry stakeholders – in the automotive, marine and aeronautics industries, charging station manufacturers, component suppliers, energy providers, grid operators, and many others – continue moving toward interoperable charging, where vehicles, marine vessels, VTOL, e-planes, high-power chargers and software systems work together to make the user experience reliable, easy and smooth. CharIN’s holistic approach is not limited to land transport. Its international community is comprised of leading global companies representing every link in the e-mobility value chain, and multiple experts have been working together as a team to drive the requirements for charging all kinds of battery-powered transport systems. A special task force has extended the scope to commercial vehicles, thus setting requirements and standards for the development of the megawatt charging system (MCS up to 5MW). In the near future, the MCS will also be used to charge other heavy-duty transport systems like e-ferries, e-ships, e-VTOL and e-planes.
