Marine Service was the Dr Karl-Heinz Kramer group’s first company when it was originally established back in 1958 by Christian Kramer’s grandfather, Dr Karl-Heinz Kramer.

And through that company, Chemikalien Seetransport (CST) was borne in 1969. Its name stems from the fact the first managed vessel was a chemical tanker. Today, the focus is more on product tankers, of which there are 15 in the fleet.
