Historie of G&S

It started on the top floor at the Coolhaven. Here, the Groenendijk & Soetermeer company, was established as a partnership in 1946 and offers conventional and advanced maritime technology and architectural maritime services to shipowners, operators, brokers and shipyards.
The first assignment was the "SS Biervliet", a ship that was confiscated by the Germans during the second world war. It had to be repaired and modernized after the war. Over the years, orders became bigger and bigger. The largest ship that we have designed (in part) is the Chevron Kentucky. 344.36 x 51.87 x 25.61 meters with a load capacity of 253,554 tons (in 1971 for Keppel Verolme).
