The new containerships are expected to be financed from current liquidity and additional borrowings.

All six vessels will feature emissions reduction technologies and be scrubber-fitted.

Earlier this month, Seaspan signed agreements with another major shipyard for a further six 15,000 TEU containership newbuilds.

The deliveries of these containerships are expected to begin in the fourth quarter of 2023.

Seaspan’s global fleet includes nearly 127 vessels with approximately 1,073,200 TEU capacity.

Since December last year, the company has ordered as many as 37 newbuild vessels and acquired two second-hand vessels, increasing their total fleet capacity to 1,653,200 TEU.

The company stated that the new vessels will enhance its fleet composition, especially its core 10,000 TEU to 15,000 TEU size category.
