INCORPORATING

RH MARINE MICRO TURBINE TO BE SUPPLIED FOR YACHT REFIT

Wednesday, September 11, 2019 

65-year-old motor yacht 'Istros' will become the world's first with a micro turbine for its on-board power generation. which will make the refitted ship cleaner, quieter and more comfortable, while meeting the strict emission standards in ports and coastal waters.

The vessel, 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. First, it has been completely stripped and the hull renewed and reinforced. Recently Feadship started rebuilding the Istros into a state of the art motor yacht with the latest technologies.

One of these new technologies is a Capstone DC 65-D Micro Turbine DC generator, supplied by maritime system integrator RH Marine for the on-board power generation. This micro turbine runs at a very high speed, thus producing less vibration and noise than a conventional diesel generator. Moreover, it is relatively small and light weight and takes up little space.

In comparison with a conventional diesel generator, the micro turbine requires very little maintenance. There is only one rotating part, an air-bearing, which does away with the need for lubricating oil and cooling water. As the turbine has lower emissions than conventional generators, it can meetIMO Tier-III emission regulations. “For yacht owners it is very important that the micro turbine is clean, otherwise they are not allowed in various ports or coastal waters in Europe and the US,” said Technical Product Manager Michiel Post of RH Marine.

RH Marine has adapted the micro turbine in such a way that it has been approved by Lloyds Register for maritime use. “Together with Seven Turbine Power we form a consortium that is the only one that can supply a micro turbine with marine certification. That gives us a leading position in the market,” says Post.

The micro turbine is slightly costlier and uses slightly more fuel than a conventional diesel generator, but that is more than offset by lower maintenance costs.

RH Marine has developed the micro turbine for the maritime industry in a partnership with Feadship, Seven Turbine Power and Boskalis. It can run on a variety of fuels, such as marine gas oil and LNG, and can be integrated with hybrid battery packages that RH Marine supplies. In combination with its own Energy Management System, this can lead up to 10% of fuel savings.
