The Dutch shipbuilders from Ferus Smit have launched Lidan and Spiken, the first in a series of six 4th generation of dry cargo freighters designed for trading through the Trollhätte Canal and in the Lake Vänern.
Each 80 by 13.35 metres, 5,100 tonnes of deadweight, 1B Ice Class vessel offers 206 thousand cubic feet of capacity across two holds.
Lidan and Spiken have nozzled propellers and reduced engine output. "With a large diameter propeller operating within a nozzle, it delivers increased thrust at lower speeds, reducing power demand during challenging seaways and ice-breaking operations. This advanced design allows us to reduce the installed main engine power by 18% without compromising performance, resulting in decreased fuel usage and carbon emissions," the ships' owners from Erik Thun highlighted in a press release.
The two first Trollmaxes also feature battery packs (that enable peak shaving and power smoothing), optimized bulb forms, transom shape, and closed bridge wings. Lidan and Spiken can also connect to an onshore power supply facility.
