How Does A Ribcraft Hybrid RIB Work?

Ribcraft Hybrid RIBs are equipped with diesel inboard engine and hybrid motor (twin or single depending on Ribcraft model selected).

The Hybrid System works in three specific modes:
1). Electric Mode -ZERO emissions and noise;
2). Diesel Mode – in which the diesel propels the vessel while also charging the batteries (Regeneration Mode);
3). Booster Mode – a combination of battery-driven electric motor and diesel engine both driving the shaft for maximum thrust for maneuvering.

Hybrid System Explained - The Electric Mode

The hybrid system architecture incorporates a clutch and transmission that enables the vessel to operate in an electric-only mode for completely emission free and silent running. The energy flows from main battery to electric motor. Batteries can charge up to 20% in just 15min of charge on regeneration mode. The hybrid system allows electric to diesel transition at every lever position.

Hybrid System Explained - The Diesel Mode

In classic diesel mode, the drive energy is provided by the conventional diesel engines. It is possible to operate speed and direction using the hybrid system lever.
During diesel mode cruising, it is possible to use part of the combustion engine power to recharge the hybrid battery (regeneration mode). Regeneration mode reduces power to propeller, therefore this should be avoided during mooring, emergency or rough sea conditions. For the same reason at low speed the generation power is reduced to avoid a diesel engine stop.
