Having LaPasserella means that there is no hydraulic control unit and therefore there is no oil in the system itself or in the engine room. Furthermore, the use of potentially polluting materials such as plastic or rubber pipes is reduced. Thanks to LaPasserella the amount of energy used on board is reduced since the hydraulic power of the engine is not required. Energy is optimised, since the electronic control panel uses less current to operate the gangway, thereby avoiding excessive stress on the system or on the vessel. It can be operated with either a 12 Vdc or a 24 Vdc power supply.
