The New York-listed owner is said to have shortlisted the Koje-based shipyard to build up to six ultra-large containerships (ULCs) in a deal that will run to $930m if options are exercised.
Market players say SHI and Hyundai Heavy Industries (HHI) were vying for the 20,500-teu newbuildings but the former won the race after offering a better price.
Costamare is said to be paying $155m each for its four firm newbuildings, with a further two options priced at the same level.
