This presentation will focus on the design aspects of high-capacity shore charging systems for battery-electric and hybrid vessels, along with the evolving regulatory framework governing these systems in North America. The session will begin by defining the key technical and economic drivers establishing the need for shore charging systems and the use of onshore energy storage. The presentation will then pivot into a discussion of the current regulatory landscape in North America and the challenges it presents with commercially available equipment. The session will give the audience insight into defining the overall ship/shore-side architecture and highlight the need for an integrator that can deliver a complete solution.

Using electricity from shore to stop the engines in ports has been technically possible for many years but now we see the demand for this increasing. In recent years many hybrid or full electric vessel take advantage of shore charging infrastructure. We will explain the options, market trends and why it is very easy for ports and owners to get shore power to reduce emissions in ports and recharge vessel batteries.

The world’s transportation infrastructure is moving rapidly toward the use of electric vehicles – cars, trucks, buses, trains and more. But when it comes to maritime vessels, the equation is a bit more complicated since there aren’t any ‘charging stations’ out at sea. It isn’t possible to have, for example, e-ferries without a reliable, cost-effective and energy-efficient charging infrastructure in place. In this presentation, Guillaume Clement will present his company’s vision for electrifying vessels to reduce emissions in ports and comply with regulations. He will also show how to create a zero-emission ports and harbors solution architecture that will make it easier and more feasible for ship designers and port authorities to design, build and welcome to their shores the latest generation of sustainable vessels. The presentation will focus on the energy storage solution for vessels as well as the onshore infrastructure.

Contributing 2.5% to worldwide CO2 emissions, marine traffic is challenged to reduce its impact. IMO 2030 and 2050 targets mark a goal in which electrification is one part of the equation. The paper reports charging solutions for ferry electrification projects between 0.5 and 15MW and land power supply systems for freighters, bulkers and cruise liners. The recent solutions provided help to swiftly take the benefit of the CO2-saving potential that battery ferries and land power supply offer. We will showcase recent solutions for various types of vessels and individual ferry and terminal operator needs.

The presentation will outline the background and plans to bring shore power to Canada’s busiest cruise port of call.

With funding from the Maritime Administration, Glosten worked with Sandia National Labs and Scripps Institution of Oceanography in 2017 to determine the feasibility of an all-hydrogen-fueled coastal research vessel. Though feasible, the vessel exceeded the available budget and was larger than what was immediately needed by Scripps. A follow-on study was recently completed that assessed and compared the technical and economic feasibility of a 125ft battery-hybrid or hydrogen-hybrid coastal research vessel. Following the study, Scripps has recently received US$34m from the State of California to build the hydrogen-hybrid variant.

The first marine hybrid was built in 1907. It took about 100 years for the next one to appear. Since the beginning of this century there has been a steady growth in interest in hybrid. With changing legislation and attitudes, marine hybrids have become a rapidly expanding market. In the last 18 years we have pioneered the application of small parallel hybrids for many vessels. This presentation will highlight a number of varied projects and will present case studies for systems we have implemented in Canada and the USA. We will also try and bust a few myths in the process.

The project will develop a toolkit of methods and software tools to be used by the industry when designing and constructing inshore vessels, and hopes to pave the way for lower-priced, environmentally friendly transportation for other routes globally.

Zero-emission fast ferries are viable today. Advances in batteries, fuel cells, vessel design and innovative financing make them a real choice. Advanced LTO marine batteries are safer, charge three times faster and have a service life five times longer than previously. Vessels with lower weight (carbon fiber) and less friction (foil-assist) use less energy and have longer range. In addition, standardized, serial production together with a single platform (battery and fuel cell) make them great value. With innovative finance (e.g. Boatplan Stockholm 2025), long-term bareboat charter allows ferry operators to get started immediately.

The Marilyn Bell I will be the first truly zero-emission, Li-ion ro-ro ferry in Canada, with the conversion underway with Canal.

Having assembled a design review team of professional seafaring experts and researchers, MCST has been investigating the transport needs of Pacific Island Countries and devising what must be done to deliver a vessel that provides wind-assisted ship propulsion (WASP) that can accrue fuel/emission savings exceeding 25% over BAU while meeting operational/safety parameters in all voyaging scenarios.

WEBBCo and East by West Ferries, along with their technical partners, will share insights into how they focused on and achieved efficiency across the board with the design, build and operation of Ika Rere, the first 100% battery-electric high-speed passenger ferry in the southern hemisphere. They will discuss how a common collaborative approach and a focus on weight were critical factors. Plus, the specialists behind the naval architecture, electrical systems and composite structures will highlight key considerations and challenges they had to overcome in each of their areas. Launched in August 2021, the 19m zero-emission composite catamaran carries up to 135 passengers on its commuter and tourist route across Wellington Harbor in New Zealand.

The rapid advance of numerical modelling, Model Based Design (MBD), metamodel-based global optimization, and intelligent system techniques provides new opportunities for the design optimization and optimal control of clean marine propulsion systems on an integrated platform. The next-generation clean marine vessels use diesel/natural gas or hydrogen fuel cell engine-based hybrid electric propulsion systems to meet the heavy-duty propulsion demand, improve energy efficiency, reduce harmful emissions, and lower ship-induced noises. In contrast to the design of standalone mechanical or electrical drives, these systems consist of many sub-components, including mechanical and electrical systems, electrochemical energy conversion processes, and system controls. Their unlimited states of operation and unique vessel design and operation profile demand collaborative design and control optimizations on an integrated modelling, design and control optimization platform to achieve the best overall performance. A new and generic approach for addressing this challenging issue is presented and demonstrated using an actual marine vessel's design and operation data. The performance, energy efficiency, carbon dioxide equivalent emissions and life cycle costs of representative traditional and next-generation marine propulsion systems are compared.

Maritime drive systems are part of rapid innovation. New system topologies based on DC distribution and the integration of energy storage systems are key for a more sustainable future of shipping. In consequence, the complexity of electrical topologies is increasing and posing new challenges and risks for system integrators and ship owners . A game-changer for successful realization of maritime drive systems is the utilization of hardware-in-the-loop simulation and virtual commissioning. In this presentation, these approaches will be introduced and illustrated with the latest use cases from maritime applications.

Zero-emission maritime transport relies on electrochemical energy storage and conversion technology such as hydrogen fuel cells and lithium-ion batteries. Determining the optimum energy storage system sizing and operational profile is an intricate task that can have a significant impact on the lifetime and cost of the ship. In this talk, Dr Simon Clark from SINTEF Industry presents a new cost and performance optimization platform aimed at accelerating the design of emission-free shipping.

The session will go into the question how to simplify advanced testing tasks related to electric/hybrid propulsion systems. Beyond pure power and efficiency measurements, it 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 the presenter will discuss how to handle the testing of drives with voltages > 1000 V more than > 3phases or multiple motors/generators (a common sight in the maritime industry).

The presentation will outline various energy carriers and describe aspects that influence operational logics for optimized operation between an energy carrier and energy storage. Corvus uses its experience as a world-leading energy storage supplier to present a few simple examples and reflections on future sizing logics related to the cross-optimization between energy carriers and energy storage systems, as well as the need for different solutions for different vessels in the future, ensuring a green and sustainable path forward.

Mechanically speaking, no modern ship is designed, tested and built without 3D CADCAM. However, the same cannot be said of the digital control and electric power systems and the loads they serve aboard vessels today. Controller hardware-in-the-loop (CHIL) testbeds are required to close this gap today and provide the foundation for lifecycle engineering and the digital twin of tomorrow.

BAE Systems, a leader in electric propulsion, will introduce its next-generation power and propulsion system for the marine market. The technology will provide a flexible solution to vessel operators, with increased electrical efficiency and vessel range to help them reach zero emissions. The technology leverages the company’s 25 years of experience developing and integrating electric propulsion systems. The HybriGen Power and Propulsion next-generation system builds on that core technology for vessels but uses smaller and lighter components for increased electrical efficiency, increased propulsion power and a simplified installation process. The modular accessory power system (MAPS) and modular power control system (MPCS) allow for a scalable, tailor-made solution to fit the specific power and propulsion requirements of each vessel, ranging from sailboats to tugs and passenger ferries.

A marine transmission serves a critical role within the context of the overall propulsion system, particularly for electric and hybrid vessels. There are multiple possible approaches for hybrid/electric propulsion, including transmissions with PTI configurations, parallel hybrid arrangements with specialized power-splitting transmissions, and fully electric drivelines with transmissions featuring external lubrication systems. Transmissions must be carefully designed, selected and configured to match the needs of each application, including the desired operational modes (boost, motor generator, electric, etc).

HamiltonJet has developed a fully integrated hybrid propulsion system called EHX, which complements the company’s waterjet and controls products. To gain experience and validate the performance of the system, HamiltonJet decided to convert its own test boat, a 15m foiling catamaran named Aria, to full EHX hybrid drive. The results were demonstrated at this year’s Americas Cup in Auckland, where the boat made its debut hosting guests and customers. This presentation looks into the findings of this work and how a fully integrated solution offers the best result for boat builders, architects and owners/operators.

With electrification offering so many benefits, it’s easy to lose sight of the real purpose behind the maritime cleantech movement. This presentation will illustrate the importance of maintaining a clear focus on decarbonization for successful and financially viable maritime cleantech projects. Making the case for greater ambition in fast ferry electrification projects, using simulation results from commuter ferry services in major world cities, the presentation will offer some observations on how a focus on volume in electric and hybrid projects can steer industry and operators down the wrong course. It will also present a roadmap for a better way for operators and industry to achieve genuine decarbonization progress.

Hybrid propulsion systems offer a range of configurations to fit numerous vessel duty profiles including vessels with long waits between jobs (tugboats, pilot boats), those regularly operating at slow speeds (patrol boats, survey vessels) and those with low full-power requirements that let them rely on less costly diesel plus electric motor power boosts. The Twin Disc & Veth Hybrid Drive allows the operator of any vessel to choose between two drives – diesel-direct or diesel-electric – or a combination of both depending on the load profile, providing the optimal solution for numerous duty profiles. This presentation will help you understand various configurations and options to select the optimal system for your specific operating profile. The presentation will conclude with in-market examples of hybrid and fully electric propulsion systems.

The propulsion drives of ships are of great importance for the safety of the vessel. 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.
