Greek containership owner Euroseas has brought in Norwegian investors to co-own one of its newbuildings.

The Nasdaq-listed company said it has formed a joint venture with a group of investors represented by NRP Project Finance for the ownership of the third vessel in its four-ship series of 4,484 teu containerships under construction in China.

Under the deal, the NRP-backed investors will acquire a 49% stake in the vessel, to be named Thrylos, for about $12.2m, including transaction-related costs. The investment assumes the vessel will be financed with at least 60% debt.

The ship is scheduled for delivery in the first quarter of 2028 and already has employment secured. Upon joining the fleet, it will commence a charter contract at a daily rate of $35,500 for a period of about four years.

The transaction marks the latest step in Euroseas’ fleet expansion programme, which has seen the company steadily add modern feeder and intermediate containership tonnage.

The Thrylos forms part of a quartet of vessels ordered at China’s Jiangsu New Yangzi Shipbuilding yard. In August 2025, the Aristides Pittas-led owner exercised options for two additional vessels in the series, priced at approximately $59.25m each and scheduled for delivery in March and May 2028.

Those ships followed an earlier order placed in October 2024 for two sister vessels at the same yard, due for delivery during 2027.

Euroseas currently operates a fleet of 21 containerships and has one of the largest orderbooks among listed feeder owners. The company’s newbuilding programme now stands at 10 vessels with a combined contracted value of around $500m.

Once all ships have been delivered, Euroseas said expects to operate one of the youngest feeder and intermediate containership fleets among its publicly listed peers.

The partnership with NRP is not the first collaboration between the Norwegian investment group and companies led by Pittas. In 2023, Nasdaq-listed dry bulk owner EuroDry formed a joint venture with NRP investors covering the acquisition of two 2015-built ultramax bulk carriers purchased from UK-based Marine Capital.
