Sea Consortium of Singapore has inked another four 7,000-teu containership newbuildings worth about $292m at Shanghai Waigaoqiao Shipbuilding (SWS) — lifting its neo-panamax order tally at the Chinese yard to eight.

Shipbuilding sources said the latest deal involved optional vessels attached to an initial order at the yard for a quartet of ships signed in April.

Sea Consortium is said to be paying about $73m each for the eight conventionally-fuelled vessels. It is slated to take delivery of two in late 2023 and the others in 2024.
