Leonhardt & Blumberg Shipmanagement

Leonhardt & Blumberg Shipmanagement is a joint venture of Buss Shipping and Leonhardt & Blumberg. Founded in 2017 the company develops ship projects and operates a fleet of modern container feeder vessels. The experienced management board provides a long-standing expertise in shipping.


With the foundation of Buss Shipping in 2009, the Buss Group was able to expand their business areas by establishing their own ship owner's company in the container sector. Since then, the service spectrum continually grew: Not only the ships' management services were consistently expanded, the company also implemented a number of conversion and new build projects, and got successfully involved in the used vessel trade. In doing so, the company was able to make use of their tight-knit industry contacts with first-grade shipyards, charterers, ship financing banks and financial investors.

Since its establishment in 1903 Leonhardt & Blumberg has managed more than 180 vessels, which were in the past mostly general cargo vessels and bulk carriers. With a focus on containerships ranging from about 1.500 to 3.600 TEU capacity the company is the biggest, independent supplier in the Handysize segment.
