HES said terms were not disclosed, but previous reports have put the price at EUR 2bn ($2.45bn).
The company is one of the largest tank storage businesses in Europe, with 18 dry and liquid bulk terminals.
It handles crude oil, refined products and bio-fuels, and dry bulk, primarily iron ore and coking coal, minerals and agri-bulk and thermal coal.
