Zodiac Maritime is exercising options for a quartet of newbuildings that would take its containership orderbook to more than $1.6bn.

Shipping market sources said the diversified Monaco owner is moving on options tied to contracts for 10 neo-panamaxes at South Korea’s Daewoo Shipbuilding & Marine Engineering.

The four 15,000-teu ships the Eyal Ofer-controlled company is adding are poised for delivery in the first half of 2024, reflecting a shipbuilding market that has all but run out of containership berths for 2023 delivery.
