Accelerating electrification of marine transport
Carolina Escudero Business development manager Vattenfall Network Solutions UK
One of the options available for ferry operators to accelerate their electrification ambitions is to consider a power-as-a-service model. This allows ferry operators to concentrate on their core business of ferry operation, leaving the development, maintenance and funding of charging infrastructure and supply to experienced operators of power grids. This presentation will use the case study of the (E/S Movitz) implementation in Stockholm to demonstrate how this approach, a collaboration between Echandia Marine and Vattenfall Network Solutions, accelerated the project.

For the safe and successful operation of electric and hybrid vessels, including those vessels in service today, new standards and rules must provide practical and meaningful guidance. The presentation will describe some of the more serious marine power quality issues of today. It will provide examples of where and why things went wrong and discuss the consequences. It will also suggest how to resolve these marine power quality issues retrospectively and, more importantly, how to prevent them in the future.
Troubleshooting the CANbus for hybrid electric marine systems
Dr Chris Quigley Director Warwick Control Technologies UK
Hybrid electric marine systems contain many electronic control components linked by a controller area network (CAN) in a bus network topology. Testing the network appropriately can help uncover problems caused by bad CAN system design or electrical component aging. These problems can be latent faults, requiring only one component failure to cause total system failure. Methods including fault insertion testing and close examination of the CANbus electrical signal will be discussed to show the benefits of such in-depth inspection. A case study from an actual hybrid electric drive system on a yacht will be presented.
Two-stroke-engine-based hybrid energy system
Markus Wenig Simulation expert WinGD Switzerland
A hybrid energy system with two-stroke engines has multiple advantages. While consistently operating at its optimal point and being the most efficient energy producer on board, the two-stroke engine combined with a PTI/PTO and electrical energy storage devices, interacting through a smart energy management system, contributes to a reduction in operating cost and emissions. In this presentation, we will give an insight into the gains possible by intelligently balancing the energy demand and supply. The challenges when designing such a system and how WinGD deals with them will also be discussed.
