Bruntons Custom Division was set up to satisfy the growing demand for solutions to increasingly difficult propulsion problems. This specialist division has succeeded in providing clients around the world with the very latest technological answers to seemingly insoluble situations.
The company is able to draw on a full range of specialists who are all employed within the Bruntons Group. Not just naval architects and designers but also metallurgists and the highly experienced craftsmen who actually build the propellers and sterngear.
As yachts and commercial craft become more advanced in both design, and the materials from which they are constructed, it is not surprising that the likelihood of being able to get a propeller 'off the shelf' is proving more and more difficult. By working with clients naval architects early on in a vessels design stage, we are able to develop exactly the right propeller and sterngear for any craft.

All Clements' high performance propellers are manufactured from high integrity castings and a full range of designs are available with a three, four or five blade configuration suitable for all types of semi and deep V planing hulls. Sizes range up to 1.2 metres in diameter, in accordance with ISO standard 484/2 and, if required, to meet the demands of classification society inspection.

A range of controllable pitch propellers is available with diameters up to approximately 8500 mm and rated for engine outputs of up to 30 000 kW.
MAN Diesel's advanced propeller blade design and calculation methods exploit the latest hydrodynamic theories and tank test results to create a propeller design that ensures maximum efficiency while maintaining low noise and low vibration characteristics.
Complete propulsion packages can be tailored to meet specific requirements by using these propellers in association with MAN Diesel two-stroke or four-stroke diesel engines and, where applications demand, reduction gearboxes

This type of propulsion system is particularly suited
to working vessels (tow-boats, fishing boats, river
bargers and pusher tugs) in the sea and on
rivers.
The nozzles can be of two types: "Fixed" or "Rotating"
(Steering Nozzles).
The advantages gained are the following:
- Reduction of propeller diameter;
- Reduction of propeller shaft and stern tube diameter;
- Reduction in vibrations, expecially in the wider stern as the nozzle regulates the water flow; - Reduction in ship's pitching when in rough waters;
- Increase in the propeller thrust to the tow and to the Bollard-Pull;
- Possible increase of ship speed by approx. 15%;
- Better performance from heavily loaded propellers, especially in shallow water;
- At the same conditions of speed, trawler work, Bollard-Pull, need 30% less power engine;
- The smaller engine cost, the reduction of fuel consuption, the high-performance of trasmission allow to recover the investiment within one or two years.

When it comes to safeguard national security, you certainly do not want to make compromises. Maritime superiority and defense readiness are of crucial importance to ensure a successful mission of naval vessels in times of crisis and conflict as well as for maintaining peace at home or abroad.
When it comes to these vital questions you want to have the best equipment available for your Navy. You want to have the world leader in innovation, design, and manufacture of naval controllable pitch propellers (CPPs) at your side: ANDRITZ HYDRO with its Escher Wyss controllable pitch propellers.
Our leadership in this domain has been acknowledged by our customers and their positive experience throughout decades of navy services. It is proved by the quality of our innovative and numerous navy references. It is demonstrated by the concept of our unique technical design.
Each Escher Wyss naval CPP is a tailor made product based on the continually improved design features and principles of a more than 45 years exclusive development of naval propellers. It is not the result of an adaptation of commercial or civil applications.
Stringent noise requirements for SILENT THRUST and absolute reliability in adverse environmental conditions are of vital importance for a successful mission of naval vessels. Additionally, an economic operation with high propulsion efficiency, easy maintainability and low life cycle costs must be ensured during peaceful times. Consequently, all these fundamental aspects are thoroughly considered in our design efforts.
