VA TECH Escher Wyss - Controllable Pitch Propellers for Shipping

VA TECH Escher Wyss, part of VA TECH HYDRO, offers more than 65 years' extensive experience in the innovation, design and manufacture of hydraulically operated controllable pitch propellers. We are the right address for projects with stringent technical requirements like:

• Navy vessels (frigates, corvettes, minesweepers, etc.)
• Fast ferries and passenger ships
• Mega-yachts (>80m length)

Of course, Escher Wyss CPPs, with their well known reliability, are also successfully operating in a variety of other commercial vessel types like:

• Cargo ships and tankers
• Harbour and ocean tugs
• Fishing vessels
• Other miscellaneous vessels

The successful and economic operation of a technically high-grade machine requires an efficient support before and after delivery of the equipment. The fact that our CPP business segment belongs to the VA TECH Group, a financially strong organization (€3.985million turnover in year 2000) with more than 20,000 employees, makes us a reliable partner during all phases of long-term projects.

CPP experience

Since the establishment of our CPP business in 1934, more than 1,900 Escher Wyss CPP plants with a total of 9,000MW have been delivered. We have realized a wide range of commercial, civil and naval CPP applications with:

• Power per propeller up to 34,000kW
• Propeller diameters up to 11,000mm
• Power density up to 2,000kW/m²
• CP propellers with up to 7 blades

Every ship is a unique masterpiece. So are our propellers with their wake adapted, customised blade design. When you need a CPP in the high power density range, you should get in touch with us.

A comprehensive system of state-of-the-art computer software for analytical engineering ensures we achieve a well-balanced solution between the conflicting requirements of propulsion efficiency, structural strength, weight and hydroacoustics.

Silent thrust for passenger vessels and mega-yachts

The purpose of the propeller is to move the ship. Every propeller you can buy will do it, with more or less hubbub – probably rather more. And perhaps that will do for an old-timey tub; but not at all for a modern passenger vessel, a mega-yacht or a cruiser of the third millennium.

The passengers on board want to listen to an opera air, to the whispering of the waves, or to the lips of the lady close by, but never to the propeller. Moreover, they demand their martinis shaken by the bartender, definitely not by the propeller. Vibrations they are looking for on the dancing floor, but not in the coffee pot wandering over the breakfast table. As a matter of fact, they pay a lot of money for an unforgettable, relaxing trip expecting a SILENT THRUST.

SILENT THRUST is the concept of adapting and transferring our achievements from the navy sector to the civil marine market to meet the increasing demands of our customers. For example, the noise level and the magnitude of the pressure pulses are the crucial points a naval propeller is judged by: the lower the better. With us you have the opportunity to profit from our technological success in the navy market. We are able to continuously consider the information from the research frontier so as to explore all avenues when optimizing your tailor-made propeller.

This navy technology spin-off appeals especially to cruise ships, passenger and RoPax ferries, as well as mega-yachts, among others. Oh, did we forget to talk about efficiency and reliability? Well, the Escher Wyss CPP's efficiency and reliability goes without saying, since 1934 all over the seven seas.
