Sustainable Transformation of the Energy Sector

Offshore potential Brazil

In the course of an increasing engagement on the Brazilian market, Johannes Dimas – Energy & Project Management act as adviser for public authorities and the industry in Brazil.

The oil & gas sector is of highly economical relevance for Brazil. Nevertheless, Brazil features with its great share of hydro power a low-carbon electrical energy production. As seen in the recent years, the hydro power production could not grant a fully reliable energy supply, due to water shortages in the dry season. That is were renewable energies like photovoltaic and wind energy come into play.

Since the second half of 2018, the emerging Brazilian offshore wind energy sector experiences some state of flux. Petrobras announced its collaboration with Equinor in the sector and to realize a first offshore wind prototype, public authorities are investigating in the offshore wind potential, and the senate started end of 2018 a legislative initiative for offshore wind farms in the Brazilian sea, as well as the Centro de Estratégias Recursos Naturais e Energia (CERNE) develops proposals for a respective regulatory framework.

In 2019 Asa Branca Wind Farm got its pre approval (DRO) for 720 MW from the National Electric Energy Agency and IBAMA held an international workshop about environmental licensing to improve the federal environmental licensing of offshore wind farms.

Promoting the Transformation

Johannes Dimas – Energy & Project Management actively promotes the sustainable transformation of the energy sector in Brazil and is partnering with national and international organizations.


RB1 Convention Center in Rio de Janeiro
The RB1 Convention Center in Rio de Janeiro hosts also the EPE headquarters

In August 2018, Johannes Dimas - Energy & Project Management held his first workshop for government agencies about the utilization of offshore wind energy. The event in the Convention Hall of the RB1 Convention Center in Rio de Janeiro was organized by the Brazilian national Energy Research Office (EPE) together with the German Association for International Cooperation (GIZ). Topics were the international offshore wind energy market, technical aspects, approval procedures, financing, and insurance; followed by a lessons learned session and a perspective for the emerging Brazilian market.

Besides the organizers EPE and GIZ, the Brazilian Ministry of Mines and Energy (MME), the National Operator of the Electric System (ONS), and the Chamber of Commerce and Industry Brazil-Germany in Rio de Janeiro (AHK-RJ), as well as local governmental agencies participated at the workshop.

In July 2019, Johannes Dimas held a presentation followed by several panel discussions at the International Workshop on Environmental Impact Assessment (EIA) for Offshore Wind Farms at IBAMA's headquarters in Brasilia (Brazil). IBAMA is the federal Brazilian Institute of the Environment and Renewable Natural Resources and is involved in the environmental licensing of offshore wind farms in Brazil. The objective of the two-day workshop was the technical improvement of the federal environmental licensing of offshore wind farms in Brazil.

Guest Lectures

The offshore wind farm Trianel Windpark Borkum II (TWB II) is the second construction phase of the Trianel Windpark Borkum. The first phase (TWB I) went already online in 2015. TWB II consists of 32 Senvion Wind Energy Converters (WEC) of the type Senvion 6.2M152 Power Upgrade with a nominal output of about 6.3 Megawatt (MW) each. The offshore site covers 56 square km and is located about 45 km north of the island Borkum in the German Bight. TWB II with a total installed capacity of about 200 MW will produce 800 GWh per year.

The supply and service contracts were already closed in September 2016. The offshore construction started in June 2018 with the installation of the monopile foundations. Completion and first production is planned for 2019.

The project was developed initially by Trianel Windkraftwerk Borkum GmbH & Co. KG, which later agreed a joint venture with EWE AG, a northern German utility. In April 2017 the shareholder board approved the start of construction (Baubeschluss) followed by Financial Close (FC). Shareholders of the special purpose vehicle (SPV) Trianel Windkraftwerk Borkum II GmbH & Co. KG are European utilities (EWE AG, ewz, Trianel GmbH and further 17 regional utilities) and FONTAVIS, an independent Swiss asset manager.

The offshore wind farm Trianel Windpark Borkum I (TWB I) is the first construction phase of the Trianel Windpark Borkum and went online in 2015. The offshore site covers 56 square km and is located about 45 km north of the island Borkum in the German Bight. The water depth ranges here from 25 to 35 meters. The estimated yearly power output amounts to 750 GWh. TWB I comprises 40 AREVA wind energy converters (WEC) of the 5 Megawatt class with a total nominal output of 200 MW and a total height above water level of 148 meters. The turbines with a total weight of more than 1000 tonnes are erected on tripod foundations with an average weight of 700 tonnes. The AC converter station is already equipped to serve the second construction phase as well (TWB II).

The one Billion Euro project is held by a cooperation of 33 municipal and regional utilities and Trianel GmbH. The special purpose vehicle (SPV) for the project is Trianel Windkraftwerk Borkum GmbH & Co. KG.

Interface Management and Multi-Contracting

Johannes Dimas was in charge of the Technical and Commercial Project Controlling for the subprojects (wind energy plant, foundations, cables, substation and logistics). During the construction phase, as the Technical Project Coordinator Installation Campaign, he managed the two separately assigned packages Wind Turbines and Installation Logistics until handover to the commissioning team.

Not least due to the delay in the grid connection, the TWB I project proved exceptionally difficult. Resulting claims, failing contractors and also an inhomogeneous and partly externally assembled project team placed high demands on the owner-side project management, in particular against the background of the chosen multi-contracting strategy.

Between 2009 and 2011 Johannes Dimas gave advice to major international companies of the wind industry from Europe, USA, and Asia on behalf of Germany's federal government. Key aspects were Foreign Direct Investments (FDI). The consulting services were offered by Germany Trade & Invest GmbH (GTAI), a 100% subsidiary of the German Federal Ministry for Economic Affairs and Energy (BMWi).

Johannes Dimas built up the wind energy division at GTAI. The services included industry business opportunity analyses, market research, industry site analysis, and Project-related financing and incentives consultancy.

One of the mandates concerned the Offshore Wind Expansion Program of GE Energy. In the year 2010, GE announced to invest 340 million Euro in offshore technologies. Investments were made in Germany (Hamburg, Salzbergen), UK, Norway, and Sweden.

The Baltic 1 wind farm is operated since 2011 by the German utility ENBW AG. The 21 turbines sum up to a capacity of 48.3 MW in total. The 150 kV grid connection has a length of approximately 77 km (16 km onshore, 61 km offshore). It links the substation shared with the wind farm Baltic 1 and the Bentwisch onshore substation near Rostock.

Due to short-term changes in the legal framework, the responsibility for the grid connection of an offshore wind farm was transferred from the project developers to the grid operators at that time. This meant that the transmission system operators had to quickly establish a functioning project organization and - as far as the offshore side was concerned - enter new technical territory.

Offshore Substation Baltic 1

As Division Manager for the western Baltic Sea (Cluster West) Johannes Dimas was the Project Director in charge for the on- and offshore Transmission Line Wind Farm Baltic I. This included the project set-up, front-end engineering (FEE), and the European tender procedure. The budget summed up to ~150 million Euro.

For Vattenfall Europe Transmission, this was the first High Voltage (HV) transition line for an offshore wind farm. In 2010 “Vattenfall Europe Transmission GmbH” was sold and is operating now under the name of “50Hertz Transmission GmbH”.

The German Pioneer Project

Offshore Wind Farm Alpha Ventus
Wind Farm alpha ventus

Alpha ventus is the first German offshore wind farm and was a ground-breaking pioneer work of the three involved utilities. The wind farm is a joint venture of EWE AG, E.ON Climate & Renewables und Vattenfall Europe Windkraft. In 2006, they founded Deutsche Offshore-Testfeld und Infrastruktur GmbH & Co. KG (DOTI) as special purpose vehicle (SPV) for the project. For all involved parties, alpha ventus was the starting point for an enduring engagement in the German offshore wind sector.

The site is located 45 km off the island Borkum in the German Bight. The wind farm launches six AREVA Multibrid M5000 converters on tripod foundations and six Repower 5M on jacket foundations. The offshore substation was already erected in 2008. The start of normal operation was celebrated on 27th of April 2010. With a nominal capacity of 60 Megawatt the wind farm is designed for a yearly production of about 220 gigawatt hours. This energy yield is sufficient to provide 50.000 four-person households with renewable energy.

Merging Technology and Management

With respect to both, the technology and the project management, alpha ventus was a challenging project for all involved organisations. Within the joint venture Johannes Dimas led the Vattenfall team that did staff the foundation, the logistic and the M&O package. He was responsible for the conceptual planning, the budgeting, the Front-End Engineering (FEE) and the procurement by tender.

Strategic Business Development

Location DanTysk (OpenSeaMap)

Vattenfall and the Munich utility Stadtwerke München (SWM) constructed the offshore wind farm DanTysk about 70 kilometres western of the island Sylt in a water depth of 21 to 31 meters. The first turbine was erected in April 2014, the first power was supplied in December 2014.

Vattenfall and SWM have founded the special purpose vehicle (SPV) DanTysk Offshore Wind GmbH (Vattenfall 51%, SWM 49%). Vattenfall had been responsible for the construction and is now operating the wind farm.

In December 2010 Vattenfall's board of directors took the final investment decision in Stockholm. In the same period, Vattenfall and SWM signed the supply contract of the offshore converter station. The substation was installed in August 2013 by a consortium of Strukton and Hollandia.

The 80 wind energy converters with a nominal capacity of 3.6 Megawatt (MW) and a rotor diameter of 120 meters were delivered by Siemens. The wind farm with a total capacity of 288 MW provides electricity for 500.000 households.

In 2018, DanTysk was awarded as the "Best Offshore Wind Farm in Operation 2017" by the Arbeitsgemeinschaft Offshore-Windenergie e.V.

Setting Standards

The application for approval of DanTysk was one of the first for an offshore wind farm in the German Exclusive Economic Zone (EEZ). Johannes Dimas did work in a small team on the project development comprising the environmental impact assessment, the first technical concepts as well as the approval procedure. The conception and the quality of the application documents including the underlying environmental impact study (EIS) have set the standards for all future application processes executed by the Federal Maritime and Hydrographic Agency (BSH).

Strategic Business Development

Much later - at this time responsible for the wind energy at Vattenfall Europe - Johannes Dimas was mapping out Vattenfall Europe's offshore strategy with the Vattenfall Headquarters. As a result, Vattenfall acquired DanTysk as well as shares on the alpha ventus offshore project.

Reducing The Carbon Footprint – The First Cut

The wind farm Jänschwalde is situated close to the city of Cottbus in the federal state of Brandenburg in the direct neighbourhood of an open brown coal pit, formerly run by Vattenfall. It is the first wind farm which was constructed by a Vattenfall Europe company itself, namely Vattenfall Europe Renewables GmbH. In the meantime, Vattenfall fully divested its brown coal mining and lignite-fired power generation in Germany to reduce its carbon footprint and besides did continuously increased its wind power portfolio.

The first construction stage of Jänschwalde was commissioned in 2004, the final in 2006. The six 2 MW Vestas V90 turbines with a hub height of 105 meters sum up to a total capacity of 12 MW. Johannes Dimas was the project manager for the construction and commissioning of the final three turbines (6 MW). As the Division Manager Wind Power at Vattenfall Europe Renewables GmbH, Johannes Dimas was also in charge for the maintenance and operation of the wind farm Jänschwalde.

Vattenfall GmbH, formerly Vattenfall Europe, is a wholly owned subsidiary of the state-owned Swedish energy company Vattenfall AB. Vattenfall Europe has long been criticized for its open cast mining and coal-fired electricity generation. In the meantime, Vattenfall has completely divested its open cast mining and coal-fired generation in Germany in order to reduce its CO2 emissions. In addition, Vattenfall has continuously expanded its wind power portfolio.

The onshore wind farm Jänschwalde marked only the first step for Vattenfall Europe. After the board approval of the Vattenfall Europe's Offshore Strategy, the engagement shifted to the offshore sector. Today, Vattenfall is one of the main players in the offshore wind energy sector and has bundled offshore wind energy as a future-proof core area throughout the Group.

Vattenfall Europe's Offshore Strategy

The screenplay for Vattenfall Europe's entry into the offshore wind energy sector was the strategy for Vattenfall Europe's strategic alignment in the offshore segment. The strategy was largely developed by Johannes Dimas together with the Corporate Development in Berlin and then presented to the decision-making bodies.

As part of a broad-based market analysis, almost all of the German offshore projects available at that time were subjected to a technical and economic review. Johannes Dimas, at that time responsible for the wind energy at Vattenfall Europe Renewables GmbH, was leading the commercial-technical due diligence teams.


Based on the Offshore Strategy, Vattenfall Europe conducted the acquisition of the DanTysk offshore wind farm project and realised its participation in the alpha ventus project. The renewable energies, that were at that time assigned to the Vattenfall Europe Generation AG or more specifically to the Vattenfall Europe Renewables GmbH, were first bundled in an independent business unit in Hamburg and later bundled groupwide. In the course of the divestment of the German fossil energy units, the Vattenfall Europe Generation AG was sold in 2016 (today Lausitz Energie Kraftwerke AG).

After having paved the way, Johannes Dimas also worked on the realization of the above mentioned key projects:

Germany's First Offshore Wind Measuring Mast

Measuring Mast (DIMAS & OVERBECK 2003)
Measuring Mast (DIMAS & OVERBECK 2003)

In 2002 the first German offshore measuring tower was built in the Mecklenburg Bay (Baltic Sea) by order of E.ON. In the preliminary stages extensive investigations of the environment and the site were carried out.

The measuring mast is located in the planning area of the wind farm Beta Baltic (formerly SKY 2000) and the planned test field GEOFReE. The offshore installation collects meteorological and hydrographical data. The data are temporarily stored on a data logger inside a converted container and transmitted by radio to the mainland.

The foundation of the measuring mast consists of a steel monopile; nearly 60 m long, and 110 t heavy. The measuring container is installed 6 m above the water line. A 12 m high measuring mast is attached to the container.

Already during the installation data about the pile-driving process, the noise emissions, and about the sediment drift were collected. The pile-driving was very challenging and confirmed the assumptions of the ground expertise.

Offshore Wind Farm Beta Baltic

Beta Baltic, formerly known as SKY 2000, is a wind farm project in the German territorial waters of the Baltic Sea. It was developed by GEO mbH and later acquired by E.ON and transferred to the special-purpose vehicle (SPV) Offshore Windpark Beta Baltic GmbH. The distance to the main land is about 20 km; water depths vary about 20 meters. The project is since several years on hold, not at least because of the difficult ground conditions (see below).

Test Field GEOFReE

GEOFReE (GErman Offshore Field for Renewable Energy) is a test field planned by GEO mbH for up to five wind energy converters adjacent to the Beta Baltic project.

Environmental Impact Studies and Regional Planning

Johannes Dimas did promote the regional planning procedure, environment impact studies, and the approval procedure of the wind farm Beta Baltic / SKY 2000 on behalf of the former project developer GEO mbH from 2000 till 2003.

In the year 2002 he became the project manager for the regional planning procedure of the grid connection. Later, due to a change in the law, the transmission grid operator (50 Hertz) took over the responsibility relating to the planning and realisation of the grid connection.

Geological Offshore Surveys

Quaternary of the Mecklenburg Bay (Baltic Sea) (DIMAS 2001, modified)
Quaternary Mecklenburg Bay (DIMAS 2001, modified)

Several geophysical surveys and a following drilling campaign were carried out at the planned site of the two wind farm projects and the measurement mast, because a first feasibility study carried out in 2000 by Johannes Dimas indicated problematic site conditions due to unconsolidated sediments.

In the following, several seismic surveys were undertaken by different geoscientist conducting various geophysical measurements. The results of all these surveys seemed to dispel the concerns regarding problematic subsoil.

However, the drilling campaign in 2002, also supervised by Johannes Dimas, could not verify the results of the seismic surveys.

On the planned site and the surrounding area the sea-bottom is built up of juvenescent, unconsolidated alluvial mud. Underneath, there are more Holocene soft sediments with very little bearing capacity. The total thickness of the Holocene sediments according to the drillings is between 14 m and 19 m. Underlying this strata is glacial till and claystone with adequate bearing capacity.

Geographic Information System (GIS)

Projektträger: GEO Gesellschaft für Energie und Oekologie mbH
Funktion: Project Management

Implementation of a Geographic Information System (GIS) for the North and Baltic Seas

In 2001, Johannes Dimas implemented a Geographic Information System (GIS) at the project developer GEO mbH. In the GIS, all geo-referenced data of the various projects in the North and Baltic Seas were merged and managed centrally. This also included the shore-side grid connections.

For a reliable data exchange, special arrangements had been closen with all involved, such as wind and environmental experts. On this basis, an integrative project development approach was promoted. Above all, this approach focuses on interface optimization and the utilisation of synergies.

Today, the use of GIS has proved to be the best way to manage the high data amount and is established throughout the entire offshore project-development.

In 1999, the geological recordings of the area northwest of Alpirsbach in the Middle Black Forest were completed. The mapping and the stratigraphic investigations were carried out in cooperation with the Geological State Office Baden-Württemberg.

The refined lithostratigraphy opens up a new understanding of stratification and deposition conditions and opens up a new understanding of the geological and hydrogeological conditions in the region beyond the work area. In 2004, the results were used for supporting the Alpirsbacher Klosterbräu Glauner GmbH & Co. KG on prospecting new brewing water in the region.

An overview profile of the Permo-Triassic overburden and a refined lithostratigraphic subdivision based on profiles of the Thuringium (z) were published in 1998/1999.
