Hartman Seatrade has signed an order for its newest heavy-lift vessel, the Hartman Class 500, a design aimed at combining higher lifting capacity with lower-emission operating options.

The company says the newbuild—set to be constructed by Rock Shipbuilding—will feature a 500-ton lifting capability, a top speed of 19.5 knots, and a deadweight of 4,600 mt. It will also be equipped for battery-electric sailing in a zero-emission mode at speeds up to 11 knots. In port, the vessel is intended to operate zero-emission, including crane work, via a full shore power connection.

While Hartman Class 500’s full general arrangement and cargo-space details have not yet been released, the order follows Hartman Seatrade’s established focus on specialised project and breakbulk transportation. In its public company profile, the operator highlights cargoes such as wind energy equipment, yachts, and heavy machinery supporting the oil and gas sector.

A recent reference point in the fleet is Southern Rock, which Hartman Seatrade describes as a 13-knot vessel with 4,540 dwt and RoRo lane capacity, supported by downloadable plans and a datasheet.
