Atlas Corp-owned Seaspan Corp has added to its Ebitda backlog with more long-term container ship charters to Israeli carrier Zim.

The 4,526-teu Seaspan Chiba and Seaspan Kobe (both built 2011) have been fixed at $43,000 per day over five years, Alphaliner reported.

This will add about $100m of Ebitda backlog for the Canada-based giant, Fearnley Securities calculated.
