Offshore wind energy (OWE) production is a crucial element for increasing the amount of renewable energy. Consequently, one can observe a strong and constant rise of the OWE industry, turning it to an important contributor of national energy provision. This trend, however, is accompanied by increasing pressure on the reliability, safety, and security of the OWE infrastructure. Related security threats are characterized by high uncertainty regarding impact and probability leading to considerable complication of the risk assessment. On the other hand, the resilience concept emphasizes the consideration of the system’s response to such threats, and thus, offers a solution for dealing with the high uncertainty. In this work, we present an approach for combining the strengths of risk and resilience management to provide a solution for handling security threats in OWE infrastructures. Within this context, we introduce a quality assessment enabling the quantification of the trustworthiness of obtained results.

The North Sea Region (NSR) contains 22 million houses built in 1950-1985 that cause 79 Mton CO2 emissions annually. Current deep retrofit home renovations are carried out on a limited-scale production and only in small projects. This results in the problem that nowadays renovation costs are way too high and the pace of renovation is far too low. Large scale renovations of existing homes towards energy-neutral are currently not addressed in the North Sea Region. Still, the retrofit of houses in the North Sea Region is essential to reach the European energy and climate objectives. However, the building sector in Europe is not creating the necessary production facilities. The target of the just started INTERREG project INDU-ZERO is to develop a blueprint for a production facility that can produce wide suitable renovation packages at a high volume and low cost.

Die Blockchain-Technologie gilt mittlerweile als eine der größten Erfindungen und Innovationen der letzten Jahre und nicht zuletzt sehen Experten in ihr das Potential, eine Vielzahl von Industrien, wie auch die Schifffahrtsindustrie, nachhaltig zu verändern. Inhalt des vorliegenden Beitrags ist es zu erläutern, was die Blockchain-Technologie ist und wie ihre Möglichkeiten in der maritimen Logistik genutzt werden könnten. Neben der detaillierten Darstellung zu den Anwendungsmöglichkeiten in der Schifffahrtsindustrie werden zudem die Risiken sowie Probleme bei der praktischen Umsetzung untersucht.
