Events in brief VGB PowerTech 7 l 2020 52. KRAFTWERKSTECHNISCHES KOLLOQUIUM am 6. und 7. Oktober 2020 Air Products and thyssenkrupp sign exclusive strategic cooperation agreement for world-scale electrolysis plants to generate green hydrogen. Electrolysis plant. “The SCA with thyssenkrupp is an important element of our value chain in developing, building, owning and operating worldscale projects and supplying green hydrogen for mobility, energy and industrial applications. We look forward to applying our complementary strengths and delivering substantial sustainability benefits through transformational green hydrogen projects,” said Dr. Samir J. Serhan, Chief Operating Officer at Air Products. “We are proud to cooperate with Air Products in making value chains for fuels, chemicals, and industry feedstocks sustainable. Large-scale electrolysis is the key technology to connect renewable power to the different sectors of mobility and industry. As a world market leader in electrolysis we bring in both: technology and production capacity at scale. Already today, we are set to supply one gigawatt for water electrolysis plants per year, and we are prepared to ramp up the capacity in this rapidly evolving market,” said Denis Krude, CEO at thyssenkrupp Uhde Chlorine Engineers. thyssenkrupp has developed high-efficiency alkaline water electrolysis technology. With more than 600 projects and electrochemical plants worldwide with a total rating of over 10 gigawatts realized, thyssenkrupp has extensive in-depth knowledge in the engineering, procurement, and construction of these plants. Matching the need for low-CAPEX, low- OPEX, reliable technology and solid project execution to make world-scale green hydrogen projects feasible, Air Products and thyssenkrupp are committed to deploying economic green hydrogen plants in the gigawatt size.

As a result of both the directions provided by the European Centre for Disease Prevention and Control and Italian governmental public health authorities, we are obliged to reschedule the event to best ensure the safety of our customers, attendees, staff and suppliers. Enlit Europe will now take place on 30 November – 2 December 2021 at Fiera Milano di Rho, Milan. Stay tuned for the Online Platform This major resource was intended to be launched at Enlit Europe in Milan. Yet, with the physical event being rescheduled to take place in 2021, one thing is clear – our need to accelerate the development of this online platform is critical. From July 2020 onwards, Enlit Europe will host its programme online, through live sessions, interviews, panel discussions, networking breakout sessions, we will make sure the discussion happens online in an environment that is beneficial to our community. Interested in signing up for this platform?! LL www.enlit-europe.com • Präsenz • Web • Hybrid (kwt) 2020 ist ein besonderes Jahr. Die Digitalisierung bringt viele Vorteile – dennoch bleiben persönliche Kontakte sehr wichtig. Für das 52. Kraftwerkstechnische Kolloquium haben wir gemeinsam mit dem Internationalen Congress Center Dresden ein zertifiziertes Veranstaltungs- und Hygienekonzept entwickelt, das ein persönliches Treffen mit Fachvorträgen und Firmenmesse ermöglicht. Daher planen wir eine Präsenzveranstatung und bereiten zeitgleich eine Webveranstaltung für all diejenigen vor, die nicht vor Ort in Dresden dabei sein können.. Themenschwerpunkte 2020 • Innovationen/ Innovationen in der Energietechnik (Kernthema der Plenarveranstaltung und der Podiumsdiskussion) • Neubau- und Pilotprojekte in der Kraftwerkstechnik • Integration regenerativer Energieträger/ Sektorkopplung • Energiespeicher • Versorgungsnetze • Verbrennung und Dampferzeuger • Kernenergetische Systeme • Energiemaschinen • Abgasreinigung • Prozesssimulation, Messtechnik und Digitalisierung • Armaturen und Komponenten • Betrieb und Instandhaltung Veranstaltungs- und Hygienekonzept Vor Ort In Sachsen sind Veranstaltungen mit unter 1.000 Besuchern unter Einhaltung bestimmter Regeln derzeit wieder möglich. Wir freuen uns sehr, dass wir auf Basis der aktuell geltenden Veranstaltungsregeln und in Abstimmung mit dem Internationalen Congress Center Dresden ein Konzept für die Durchführung unserer Veranstaltung erstellen konnten. Dieses wurde von unabhängiger Seite geprüft. Die zugehörige Bescheinigung ist auf den Webseiten des Kraftwerkstechnischen Kolloquiums einsehbar. Ob Vor Ort oder digital – in jedem Fall energetisch vernetzt. LL www.tu-dresden.de 34
VGB PowerTech 7 l 2020 Technical risk management of hydropower plants Technical risk management of hydropower plants Wolfgang Hamelmann, Klaus Engels and Peter Struckmann Kurzfassung Technisches Risikomanagement von Wasserkraftwerken Beim Betrieb und der Instandhaltung eines großen Portfolios von Wasserkraftanlagen besteht die Herausforderung für den Eigentümer und Betreiber darin, zu entscheiden, welche Investitionen zur Risikominderung und welche Instandhaltungsmaßnahmen wann an erster Stelle stehen sollten. Dies gilt insbesondere dann, wenn die Ressourcen an Personal und Budgets begrenzt sind und die Rentabilität der Anlagen optimiert werden muss. Die Situation erfordert eine effiziente und rationale Priorisierung von Aktivitäten und eine entsprechende Zuweisung von Budgets. Aber wie können die richtigen Kriterien und Investitionsprinzipien bestimmt werden, wenn das Gesamtziel ein sicherer, zuverlässiger, konformer und wirtschaftlicher Betrieb der Anlagen ist? Dieser Beitrag skizziert, wie ein Anlagen-Risikomanagementsystem bei dieser Bestimmung unterstützen kann. l When operating and maintaining a large portfolio of hydropower assets, the challenge for the owner and operator is to decide which risk mitigation investments and maintenance activities should come first, and when. This is especially true when resources in personnel and budgets are limited, and the profitability of the plants must be optimized. The situation requires an efficient and rational prioritization of activities and corresponding allocation of budgets. But how can the right criteria and investment principles be determined, if the overall target is safe, reliable, compliant and economical operation of plants? This article outlines how an asset risk management system can assist in this determination. Uniper is an international energy company with approximately 11,500 employees and activities in more than 40 countries. The group operates around 180 hydropower plants in Germany and Sweden as well as a number of coal- and gas-fired powerplants, with a total installed generation capacity of about 34 GW, and gas storage sites with a capacity of approximately 7.9 x 10 9 m 3 . Its main activities include power generation in Europe and Russia, as well as global energy trading, including a diversified gas portfolio. Motivation for setting up an asset risk management system Since its establishment, Uniper has been committed to improving the way it manages asset-related activities at optimum lifecycle cost, without compromising health, safety or environmental performance, or its reputation. The operation of physical power generation assets is a risk-driven business. Therefore, operational risks and their mitigation measures need to be systematically identified and prioritized to achieve an acceptable risk profile in an environment of significant cost pressure; this has led to the creation of ROME (risk-based O&M excellence), which allows Uniper to handle assets in the best way possible, applying a riskbased approach within a learning organization aiming for continuous improvement. ROME is composed of multiple risk management methodologies that in turn provide for a safe and efficient generation business. The main methodologies, Bow- Tie and AERO (asset engineering risks and opportunities), applied in Uniper’s hydropower business (and across the entire generation fleet), will be presented in the following sections, as part of the asset risk management system. Do we understand what can go wrong? Hazard identification BowTie, O&M inspections, insurance audits Authors Wolfgang Hamelmann Asset Risk Uniper Kraftwerke GmbH Düsseldorf, Germany Dr. Klaus Engels Director Operations Hydro Germany Uniper Kraftwerke GmbH Landshut, Germany Dr. Peter Struckmann Director Asset Risk Uniper Kraftwerke GmbH Düsseldorf, Germany Do we learn from incidents? BSCAT Root cause analysis Learning Organization Securing compliance to legislation on Process Safety Risk assessment BowTie AERO (PT-Risk) Risk Based Scoping MOT, OSTRA, RAWE (Standard) barrier identification Do we know what are the systems in place to prevent things going wrong? BowTie Fig. 1. The ROME concept for managing operational risks and opportunities. Do we know that these systems will work when needed? Do we know the risk in case of missing or less effective barriers? 35
