Adani Ports and Special Economic Zone (APSEZ) has secured a 10-year marine services contract tied to Argentina’s first liquefied natural gas export project, the company said on Monday, extending its international marine operations to South America for the first time. The contract was awarded to The Adani Harbour International FZCO, a step-down subsidiary of APSEZ, in consortium with Argentina-based Meridian Group. It follows a global competitive tender by Southern Energy S.A. (SESA), the project developer.
