Our owner family has been active in shipping for three generations. In the mid-1970s, we began our involvement as a second business line alongside the then existing trading business. In 1991, we founded ASC 'Alster Ship' Chartering GmbH & Co. KG, whose success in the European market paved the way for the establishment of our own ship management company. BAS was founded in 2001 and has since become a dependable partner for shipowners in the European and North African markets.
Today, we manage a modern fleet of six bulk carriers and look forward to the delivery of 4 Groot 5200 XL new buildings in 2026.
