Nasdaq-listed container vessel owner Diana Containerships has added one more Post-Panamax to its fleet.

Diana, through a separate wholly owned subsidiary, received the 2008-built m/v Rotterdam on Sept. 10.

The company inked an agreement to buy the 6,500teu Rotterdam for US$37.5m back in July.

Including the newly delivered Rotterdam, Diana Containerships' fleet currently consists of 14 container ships ranging from 3,426teu to 6,541teu in capacity.

The company also expects to take delivery of one more 6,500teu boxship – the 2009-built m/v Hamburg – by the end of November 2015.
