US-listed Greek bulker owner Seanergy Maritime is stepping up its fleet renewal drive, adding two Japanese capesize newbuildings while offloading an older vessel.

The company said it has agreed to acquire a 181,500 dwt scrubber-fitted capesize under construction at a Japanese yard, with delivery expected between the second and third quarters of 2027.

In a second deal, the owner has secured another 181,500 dwt capesize through a 10-year bareboat-in arrangement for a vessel to be built at the same yard and delivered in early 2029. The deal includes a purchase option that can be exercised from year five through the end of the charter.

The combined cost of the duo is estimated at about $158m, assuming the purchase option is exercised.

The latest move expands Seanergy’s newbuilding programme to five vessels — four capesizes and one newcastlemax — with a total investment of roughly $384m, and deliveries scheduled between 2027 and 2029.

Chairman and chief executive Stamatis Tsantanis (pictured) said the company is using the current market to replace older tonnage with modern, fuel-efficient ships with favourable delivery positions.

Alongside the newbuilding push, Seanergy has agreed to sell the 2010-built capesize Squireship for $29.5m to spinoff United Maritime.

Delivery of the 170,018 dwt vessel is expected between late April and early June 2026. After repaying associated debt, the sale is expected to generate net proceeds of about $13.5m and an accounting gain of roughly $4m.

Seanergy will continue to provide technical and commercial management for the vessel after the sale, allowing it to maintain the ship’s existing employment.

The disposal follows another recent transaction with United Maritime involving the 2010-built Dukeship, which was placed on an 18-month bareboat charter with a purchase obligation at the end of the period.

Seanergy currently owns or finance-leases 20 ships — including 18 capesizes and two newcastlemax bulkers. Once the newbuildings are delivered and the Squireship exits the fleet, the company expects to control 24 large bulkers.
