EMDEN. Emden. June saw the appointment of Christoph Kolter to the role of manager of the port office in Emden, the central contact point for shipowners, customers and service providers. He succeeds Frank Herbig, who retired after 29 years of service to the ports of Lower Saxony. „With his authoritative manner and experience, Frank Herbig was a firm anchor in Emden‘s port,“ says Volker Weiß, NPorts manager in Emden.
