Greece’s Navios Maritime Holdings has carried out a management shake-up of its South American tanker and ports business as it sets its sights on growth.

Navios South American Logistics (NSAL) owns three ports and eight small clean tankers.

“Because of the renewed global focus on food and energy security, we believe there is a significant commercial opportunity in the Hidrovia region,” Navios Holdings chief executive Angeliki Frangou said.
