The superyacht Istros will be equipped with the world’s first microturbine suitable for marine use for its on-board power generation. This makes the refitted ship cleaner, quieter and more comfortable, while it can meet strict emission standards in ports and coastal waters.

The Capstone DC 65-D Micro Turbine DC generator, specially developed by maritime system integrator RH Marine in a partnership with Feadship, runs on diesel fuel and delivers a direct current. The DC power output is used to charge the connected ‘peak-shaving’ battery pack, from where the main busbar is supplied via a DC-AC converter.

Microturbines are widely used in the aviation and offshore industry. The reason they have not been installed on yachts before is that there has been no marine certification so far. RH Marine has adapted the microturbine in such a way that it has been approved by Lloyd’s Register for maritime use.

The 42-meter motor yacht, originally built in 1954, is being completely rebuilt by Feadship, the joint venture of the Dutch shipyards Royal Van Lent and Koninklijke De Vries Scheepsbouw. The all-new Istros is due to be relaunched before the summer of 2020.
