Incorporating Clean Shipping International


Tuesday, September 18, 2018 

Dutch electrical and automation systems integrator RH Marine has introduced pre-engineered hybrid packages to convert superyachts’ conventional power systems to battery powered hybrid solutions. A hybrid system can reduce operational costs and increases passenger comfort at sea but while newbuild yachts have long opted for the hybrid solution, the owners of existing tonnage are now looking at retrofit solutions.

To this end, RH Marine has developed three pre-engineered packages that can be installed onboard an existing yacht during a refit. The three packages vary in size and energy storage from 250kWh up to 750kWh.

Adding batteries as an extra power source allows the generators to run on an optimal load, increases comfort due to reduced noise and vibration, and optimises manoeuvres without having to run the engines, when entering a harbour or diving in emission control area’s (ECAs). The hybrid solution also guarantees a reliable shore supply, solving the problem of blackouts in harbours and allowing complete silence on board during anchoring while the hotel load runs on batteries and engines can be switched off.

RH Marine’s award-winning Rhodium Energy Management System (EMS), using a self-learning artificial intelligence algorithm, automatically distributes the power demand over the available diesel generators and batteries. The system controls all energy sources to operate on their most optimal point, thus ensuring optimal operation given an (operational) goal. The Rhodium hybrid solution already runs on multiple including a prizewinning 80+ meter superyacht. 
Deployed in the unpredictable sailing profile of a yacht, it has proved 11% fuel savings and 32% reduction of generator running hours, thus reducing engine maintenance costs with 50%

“With RH Marine’s hybrid power system you can enter any harbour or anchor at sea everywhere on electric mode without smoke or noise and more comfortably. Our clients in all industries realise that hybrid is the future. Hybrid already has its position in the leisure market, and it is there to stay,” says RH Marine Product  Manager, Hybrid Portfolio, Despoina Mitropoulou.
