Co-founder & chairmAN

Manfred heinrichs

Mr. Manfred Heinrichs has a long-standing career within the maritime industry and has accomplished a lot through his almost 40 years of experience. 

His ethics, strong personality as well as outstanding leadership skills proved to be the means with which he established and maintained his company and the people surrounding him with great success. 

Throughout his career, he always managed to stay insightful, which led to the success of his professional endeavours. 

Mr. Heinrichs is the founder of Internaut Shipping GmbH. Founded in 1988 and headquartered in Bremen, Internaut Shipping GmbH had a strong focus on the trade with North Africa, mainly with Algeria. A large number of shipments with steel products, milkpowder, clay and constructions have been carried by Internaut Shipping GmbH controlled vessels. The strong relationships with shippers and receivers as well as a reliable port agency structure made it inevitable to increase the cargo volume during the years. Due to the increasing demand and the necessity to become independent from market fluctuations, Internaut Shipping GmbH decided to invest and acquire its own vessels. This expanded the company’s operations and in 2002 a branch office was opened in Cyprus.
