SCHOTTEL's Mechanical Hybrid Propulsion Solution

In a close collaboration with Svitzer of Denmark, SCHOTTEL has developed a new hybrid propulsion concept. The new concept is based on the recent SCHOTTEL Y-Hybrid thruster technology and connects a port and starboard mounted azimuth thruster in a vessel with each other. This makes it possible to drive two thrusters with either one of the main engines. The companies are now discussing a pilot project to retrofit an existing tug with the new mechanical hybrid technology. This will transform the direct driven vessel into a greener and more cost-efficient vessel.

Alexandria Port Authority Orders 4 New Tugs

It is one of the world's most important trade ports: the Egyptian port of Alexandria, a metropolis of some 4 million inhabitants. Located right on the western end of the Nile Delta, the port handles container and cruise vessels bound for the Suez Canal. Following the opening of the Suez Canal expansion in August, Egypt is hoping for a significant increase in transiting vessels. The Port Authority has placed orders for a total of four new additional port tugs equipped with Voith Schneider Propellers (VSP) with two Egyptian shipyards.

LNG-Powered, Electric Engine, Boxship Concept Design

French LNG containment specialist GTT, along with French containerline CMA CGM (and its subsidiary CMA Ships) and classification society DNV GL have released a technical and feasibility study for a new mega boxship dubbed the Piston Engine Room Free Efficient Containership (PERFECt), which could get rid of engine rooms all together. The concept vessel is LNG-fuelled, powered by a combined gas and steam turbine, and is electrically driven. Exploring this novel configuration resulted in the partners identifying and analyzing a propulsion concept that has the potential to offer a more efficient, more flexible and greener box ship design than current 20,000 TEU two-stroke diesel engine driven ultra large container vessels.

The Paraguay-Paraná river system extends over 2,500 kilometers and is characterized by alterations of the rivers' flow, dams, sedimentation, forestry, silting and pollution which have great impact on a vessel’s propulsion system.

New Propulsion Concept : Multi-function PowerhouseTug &amp

The multi-function PowerhouseTug & Barge (PTB) system is a novel design that utilizes electric propulsion in the barge and a tugboat with a set of generators as a power pack. This concept has two basic differences with traditional ATB (Articulated Tug & Barge) system. First, though the barge will have electrical propulsion gear onboard, the propulsion power will come from the tug, acting as a powerhouse. Secondly, the PowerhouseTug will be connected at the bow of the barge rather than at the stern and will be pushed by the barge when propelling. The control will be onboard the PowerhouseTug. This concept will have propulsion and operational advantage of a ship compounded with commercial advantage of a tug & barge system.

Voith Schneider Propellers for New Irish Ferry

The double-ended ferry MV Strangford has been in operation for more than 45 years, connecting the two towns of Portaferry and Strangford in the northern part of the Irish Sea. The Department for Regional Development Northern Ireland (DRDNI) responsible for the local ferry service now decided to replace the old double-ended ferry MV Strangford, which had been equipped with Voith Schneider Propellers (VSP), with a new one. The DRDNI again chose the VSP propulsion concept for the new double-ended ferry. The particular feature of this double-ended ferry is its docking at concrete ramps.
