Safe and Smart DC systems and ultra-fast fault interruption
An update on technology, regulations and practical experiences

Over the past years the maritime world has changed significantly and it will continue to do so. To be able to support larger electrical systems, capable of integrating alternative energy sources and storage systems, DC is the onboard power distribution system of choice. It has the ability to handle large power flows in a limited space with high system efficiency and low life cycle cost. However, safety remains an issue. Proper protection against short-circuit currents and power overload is essential.

During our seminar influencers in the field of power electronics, norm committee members and research and development authorities will update you on the latest developments.

12:00
Lunch
Jeroen Visser 13:00
Welcome
Mr. Jeroen Visser
Director at KWx B.V.
Pieter Vos

13:10
Standardization / laws and regulations on a global level
Mr. Pieter Vos
Senior Specialist at Royal IHC

Introducing DC-grid instead of AC-grid enables more flexibility in design of the power system configuration, such as variable speed engines, different sized engines, different fuel-type engines, energy buffers and energy recuperation. Such flexibility can be an advantage for alternative fueling options as for example LNG fueling and result in lower OPEX by having engines running in their optimum working point. Questions to be answered: ‘What are the advantages and disadvantages of using DC-grid instead of AC-grid for LV and MV solutions?’ and ‘What are the requirements for realizing a DC-grid; what is in the rules and standards?’

Mr. Pieter Vos started his career at Holec Machines & Apparaten in the DC traction development. He managed some projects with hybrid busses and hybrid locomotives before switching to the marine industry. Nowadays he’s mostly involved in trouble shooting and new developments. In this role he’s also member of IEC’s TC 18, the commission that is occupied with the IEC standards for marine and offshore installations. A new standard in progress is the primary DC distribution standard, IEC 63108.

Moritz Krijgsman 13:45
Development and design of the Zero Emissions Laboratory
Ir. Moritz Krijgsman
Senior Project Manager at Marin
This presentation will address development and design of the Zero Emissions Laboratory (physical and virtual) in general. Furthermore, we will focus on the essential role of the DC-distribution system, the required fault tolerance (overload, short circuit and earth fault) and the required system redundancy for reliable maritime operations.

Mr. Moritz Krijgsman MIMarEST is an experienced professional with a demonstrated history of working in the shipbuilding industry. He currently is leader of the Hydro Systems team at MARIN. His team develops design methods (SPEC and SysML) and conceptual ship system designs for the maritime energy transition. Moreover, a scaled physical test setup, the Zero Emission Laboratory (‘Engine room of the future’) and a numerical systems model are being developed and built.

Andreas Stockli 14:40
Protecting DC grids with ultrafast solid state breakers
Mr. Andreas Stöckli
CTO and Co-founder at Astrol Electronic AG
During this session you will get insights into the solid state DC breaker switch technology, its application possibilities and future technological developments. Some highlights:

• DC breaker switches in Industrial and Science Applications
• CERN protection of Superconducting magnets
• Air cooled DCB for general purpose applications
• DCB for high voltage application protecting RF Tetrode Amplifier
• DCB in Grid Applications
• Medium voltage (11kV) Triphase with high speed detection

Berend Evenblij 15:15
DC based systems in the maritime industry: where, why and how?
Mr. Berend Evenblij
Senior system engineer at Eekels Technology
Direct Current (DC) distribution systems have been around for many years but with the increased use of DC based power sources (e.g. fuel cells) and storage devices (e.g. batteries) the application for DC power distribution has gained a lot of momentum recently. The rationale behind the choice for DC supply and distribution for all or part of maritime systems is discussed, along with an outlook into the future.

Mr. Berend Evenblij (MsC Power Electronics 1985, Delft University of Technology) has industrial experience for DC applications for rolling stock, as well as R&D experience for DC switches and distribution systems for the Navy and maritime market. Since 2019 he is a system engineer at Eekels Technology, part of TBI. Amongst his current activities is technical consultancy for the “Groene Boog”, a large DC-infra project for a tunnel and a part a highway.

Damir Radan 16:30
Integration of marine power systems with large battery capacity
Dr. Sci. Damir Radnan
Technical Manager at Blueday Technology AS
The advantages of DC power distribution are well known for marine vessels and generally all small distributed power systems e.g. micro-grids. The most attractive advantage for the mobile applications is the high compactness. In mobility systems such as electric vehicles, trains, and marine vessels these characteristics are crucial as the space is always high premium and is taken from the payload. Unfortunately, DC systems are not at the equivalent stage of development compared to AC systems which have a long history of applications. With DC systems we need to make sure the application philosophy is aligned with the protection capabilities, to be able to avoid safely some pitfalls, which are not defined in rules and standards to adequate extent (as they are for AC systems). The aim of this presentation is to point to some challenges and offer advices how to approach to such systems.

Mr. Damir Radan holds PhD from Norwegian Technical University-NTNU in the area of marine electric power systems. He published numerous scientific and technical papers at international conferences and journals. Damir has been enrolled with major electric integrator companies in the development of new solutions. Damir has extensive knowledge in energy solutions and he made significant contributions in marine power system design, dynamics, control, energy management and system protection.

A wonderful location in the city of Rotterdam

The seminar will take place onboard the SS Rotterdam. A former steam ship dated 1959. The ship has been restored into its original state and we think the ancientness of the location is in perfect contrast with the futureproof and SMART technologies to be discussed during this interactive seminar. The SS Rotterdam was built in 1959 and was the fifth ship by this name to sail for the Holland-America Line (HAL). It is one of the most well-known post-World War II Dutch passenger ships. It experienced the last decade of the transatlantic line and cruise ship service between 1959 and late 2000. The steamship has been moored at the Derde Katendrechtsehoofd in the Maashaven port in Rotterdam since 4 August 2008. It has been completely renovated in the style envisioned by the designers and interior decorators in the 1950’s. It now serves as a floating multifunctional venue.

Spend the night at SS Rotterdam

We offer the possibility to spend the night at the SS Rotterdam at a reduced rate. More information will follow.
