Whether the potentials of the propeller design can be exploited depends largely on the

technological implementation. Using Optical Precision Measurement (OPM) MMG

guarantees the highest design accuracy in all dimensions. The propeller is scanned with

an accuracy of up to 1/100 mm – from the cast blank to the final machining – using fringe

pattern projection and an optical sensor.

Individual propellers in perfect alignment with the ship‘s operating profile are MMG’s

response to the increasing economic and environmental challenges in shipping. Under

using of innovative algorithms there are no longer limits for standard parameter such as

hull, engine and rudder, but also includes load, draughts, drift angle, ship speed, current,

wind and swell of the planned routes inside the Multidata Design Concept (MDC).

MMG developed Numerical Propulsion Simulation (NPS) to increase the design accuracy

by obtaining the hull-propeller interactions directly. By this technology it is possible to

compare quickly and cheaply alternative propeller designs depending on different vessel

speeds under different loading conditions in early design stage and detailed project

analysis.

MMG relies on Numerical Control Processing (NCP) for highly accurate machining at all

stages of production. This ensures that MMG’s design quality can be kept during all

necessary processes in order to give the propellers best efficiency even in full scale. NCP

involves all numerical processes from the most accurate free formed surfaces in CAD, best

fit algorithm just after casting to the CAM works and final quality check.

MMG has developed the Virtual Contact Test (VCT) to reduce expenditure on propeller

assembly. With VCT the conical hub bore of the new propeller is measured and aligned

precisely with the data of the existing shaft. Conventional blue bedding tests are not more

necessary.

1. Active propeller Active propeller are planned for an early assembly and will be preserved by the manufacturer according to following procedure: a) blade surface by outdoor anti-corrosion wax (e.g. TECTYL 506-EH or comparable anti-corrosion wax) b) inner hub hole by ordinary grease Furthermore the inner hub hole will be closed with discs made of wood at both sides for protection against mechanical damage. The blade edges will be covered by flexible rubber profile for a protection against damage. 2. Spare propeller Spare propeller are planned for a storage over a longer period and will be preserved by the manufacturer according following procedure: a) blade surface by outdoor anti-corrosion mean (e.g. TECTYL 506-EH or comparable anti-corrosion mean) b) inner hub hole by ordinary grease The inner hub hole and the blade edges will be protected according item 1. "Active propeller". This procedure is not valid for a package of propeller in boxes. 3. Storage of propeller over a longer period In case of regular storage of propeller the outdoor anti-corrosion mean has to be constant and homogeneous over a period of one and half … two years. In the minimum of a period of six month the protection of propeller (including hub bore) should be double checked (visual check). In case of external damage of the protection film this area has to be cleared thorough and protected again (note: same anti-corrosion mean). 4. Procedure before operation of the propeller into The inner hub hole has to be cleaned before start the assembly of propeller. The protection of blade edges (flexible rubber) and the anti-corrosion mean on the propeller surface has to be removed by a solvent (e.g. benzine, diesel oil, petroleum or other wax solvents) immediately before launching of the ship. In case of the ship and propeller are not in operation after launching for long-term a checking and cleaning of the surfaces will be recommended in order to remove any marine coating and for avoiding of additional ship and propeller resistance (friction resistance). enclosure: specification of anti-corrosion mean

GENERAL INFORMATION FOR POLISHING OF PROPELLER The following remarks are general recommendations for the preparing of polishing at the propeller surface and quality check after the carried out works during regular dry-dockings or intermediate in-water surveys. Dependent on the relation and operation conditions of the ship the propeller surface will be affected by fouling more or less. The complete propeller documentation should be available at the ship. Reference information regarding the below items can be found in the propeller manual. We recommend to contact and inform the operating company (repair shipyard, diver) before the start of the works accordingly in order to agree the working conditions and quality requirements. 1. POWER OUTPUT CONSUMPTION IN DEPENDENCE OF ROUGHNESS The surface roughness can be increased by marine fouling (algae, slime, mussels, barnacles, tubeworms), calcium fouling or erosion (cavitation, corrosion because of electrolytic incidents). Whereas the upper area of propeller blade is often relative clean and even because of the higher flow velocities the middle area and blade root can be more affected by fouling. The loss of efficiency at the propellers depends on different items: - character and rate of surface roughness - hydrodynamic details of the propeller blade 2. PROPELLER SURFACE The propeller surface should be polished only if the surface roughness has been increased visibly strongly respective fouling has been observed. Normal marine fouling should be removed firstly by brushes, fibre materials or similar tools. Surface roughness of new propeller (delivery conditions): position roughness Ra (mean roughness) propeller blade average 1.5 ... 2.0 µm / maximum 2.5 µm

MMG recommend to use only tools which polish the surfaces without any loss of propeller material. This can be special polishing pads, brushes (steel, brass, plastics) or also grinding fleece. Otherwise if grinding shall be carried out by normal abrasive discs it should be considered that the blade thickness will be reduced during every polishing of the propeller. If necessary the surface roughness can be checked by a roughness measuring device or surface roughness comparator.

3. LEADING EDGE OF PROPELLER BLADE The leading edge of propeller blade is a rounding edge manufactured by careful grinding and finishing. A careful carrying out of this area is very important because of the hydrodynamic properties of the propeller. Every deviation of the rounding edge (e.g. polygon edge) disturbs the flow along the propeller blade surface. Further all damages at the leading edge should be removed in order to avoid any cavitation erosion on the surface. If these damages cannot be removed completely with available tools these areas should be rounded and smoothed as far as possible. In case of bigger damages please contact MMG for advice and support.

4. TRAILING EDGE OF PROPELLER BLADE The trailing edge of the propeller blade is mostly a rounded edge at the inner radii and an anti singing edge from the middle to the blade tip. The anti singing edge avoids the singing of the propeller (vibration of trailing edge) in the full speed range. The shape of the anti singing edge is carried out as a sharp edge respective a parabolic arc rounding on face and/or back of the propeller blade. Any modifications of the original designed anti singing edge could be change the behaviour of propeller and are not permitted. Smaller damages can be removed by grinding and smoothing as far as possible. In case of bigger damages please contact MMG for advice and support.
