Voith’s eVSP

With the new electric Voith Schneider Propeller (eVSP), Voith is pushing ahead with the continu- ous electrifcation of its drive technologies. The eVSP features a permanent-magnet synchronous motor integrated in the propeller. The complete omission of gears reduces noise and frees space on the ship. In addition, the eVSP offers ship operators a degree of fexibility in the choice of power generation (energy source) as well as low maintenance requirements. Furthermore, the eVSP features favorably weight characteris- tics and can be mounted without any shaft train restrictions.

Electro-Hybrid Drive Debuts

HamiltonJet unveiled its new Electro-Hybrid Drive (EHX) sys- tem, which it says offers all the advantages of electric drive with the full capabilities of diesel. The system is designed to deliver lower fossil fuel consumption combined with the speed, maneuverability, effciency and safety of waterjets. With EHX, HamiltonJet delivers the electric motors, power electronics and control system seamlessly integrated with the waterjets, engines, gearboxes or clutches.

The control system manages the hybrid energy fow between engines, batteries and motors, while charging and discharging the batteries as required. There are four different modes of operation: diesel only, electric only, charging or electric boost. EHX can also be confgured for an electric-only vessel with the option of a fully inte- grated HamiltonJet solution. HamiltonJet recently acquired a 15-m aluminum hydrofoil-assisted catamaran test boat that it is reftting with the new EHX waterjets. Previously a recreational vessel used for cruising the waters of New Zealand’s Marlborough Sounds, the vessel is bound for a relaunch following the reft as the showcase for

HamiltonJet’s newest technology.
