For 105 Years: Shaping the Future with Foresight

Young Otto Diersch from Bremen entered the mineral oil business at the young age of 18, carrying oil cans and pushing hand carts. Aided by his younger brother Friedrich (known as Friedel), he filled small containers with lubricants from 200-litre barrels. He went to the port and industrial area on foot and with a handcart full of oil canisters. He found his customers at the fishing and coastal steamers and at the factories by Stephanikirchenweide meadow on the right-hand banks of the River Weser. If required, he sold small quantities by the oil can. Working together with partners, he expanded the company in the following years.

Otto Diersch had already progressed far with his down-to-earth attitude typical of the people of Bremen when Wolfgang Karstedt joined the company in 1954 and internationalised its business by importing mineral oil products directly and exporting semi-finished products. Wolfgang Karstedt and Ingeborg Diersch, Otto Diersch’s only daughter, had married in 1951.

Discovering trends and markets was the order of the day in the years of the post-war rebirth of the German economy. Under the guidance of Wolfgang Karstedt, lubricants trade was expanded to become an international gas oil import business and the chemicals division was established. This entailed substantial investments in tank storage, shipping and chemicals.

With the arrival of the sons of the third generation, Bernd, Axel and Svend Karstedt, Diersch & Schröder has evolved since the 1980s into a diverse and globally active group of companies active in trade, production and services in the energy industry and in the chemical sector. In addition to petroleum business, tank storage also underwent considerable expansion with oil stockpiling following German unification and the addition of the new German states as well as in Eastern Europe, and with the commencement by DS-Lager of molasse storage activities and transhipment.

In 1979 Bernd Karstedt joined the company, becoming managing director of Diersch & Schröder Holding together with his father Wolfgang Karstedt. Together, they forged ahead with the expansion of traditional business lines, international growth and forays into business in renewable energies. At the end of 2010, Bernd Karstedt withdrew from active business and took over as Chairman of the DS Advisory Council.

Until May 2023, the company was managed by Jan Christiansen and Henning Thiele, who continued the Group's growth trajectory. As part of the reorganisation of the business divisions, parts of Renewable Energies were integrated into the traditional oil division and the expansion of the end user business with the companies Leu Energie, Lanfer Energie and EMOVA created the basis for a sustainable positioning in the energy sector. Through organic growth, but also through the acquisition of the LEVACO Chemicals Group and Alpha Chemie, the Chemicals division became a second strong pillar. Since June 2023, the family has entrusted Jan Christiansen as spokesman of the Diersch & Schröder management board with the sole management. He will continue to shape and drive forward the strategic and operational orientation of the DS Group. DS is currently breaking new ground by investing in start-ups. Our traditional businesses also receive attractive impetus from these young companies. As CFO, Steffen Koplin has been responsible for the economic stability and finances of the DS Group since 2025.
