Swedish private equity firm EQT, controlled by the influential Wallenberg family, plans to acquire Rotterdam-based Koole Tanktransport, a leading storage terminal operator for edible oils.

The shareholders have accepted the offer, EQT Infrastructure said Wednesday, without disclosing the financial details.

Koole Tanktransport is located in the port of Rotterdam, Europe's biggest deep-sea port and home to the most significant cluster of the edible oils and biofuels industry.

The Dutch firm has been family-owned since 1943. The founding family will remain minority owner.
