The importance of the industry becomes clear when you consider the annual turnover of around 50 billion euros and the estimated 400,000 jobs in this sector. Our employees in Oldenburg have specialized in consulting in the maritime sector for many years. We are also supported by the "Logistics & Maritime Economy" industry center of BDO AG Wirtschaftsprüfungsgesellschaft.
