Propeller & Aft Ship Solutions  Page 06 | 07 Propelling ships and trade on all seas and waterways From the early days of invention and shipboard deployment of a ‘screw propeller’, the principle of which can be dated back to Archimedes – the propellers have just developed decade by decade and grown in size, power density and design complexity. The propellers’ transmission of rotational power and torque into thrust and ship propulsion turned out more and more efficiently. Today’s propeller demands and propulsion benchmarks for the individual ship applications have become very specific,...

CONTROLLABLE PITCH A versatile and high-efficiency propeller program The MAN Alpha CP Propeller designs are effectively embracing the power range up to 40,000 kW per shaft line. With no less than 23 different hub sizes, a cost and performance optimal solution is always offered. The standard series of propellers are 4-bladed configurations, with additional 3- and 5-bladed variants available. Further hub designs for the full feathering pitch setting possibility exist. Our standard blade/ hub materials are Ni-Al-Bronze, with stainless steel offered as an option - and for special demands our...

Propeller & Aft Ship Solutions  Page 10 | 11 CONTROLLABLE PITCH Efficient propelling of vessels with varying propulsion demands MAN Alpha CP Propellers are ideal for ships with varying operational modes and propulsion patterns ranging from dynamic maneuvering and bollard pull conditions to economical part-load service and full speed steaming. Our CPPs are versatile propulsors which meet the challenges of many different applications – and deliver excellent propulsion performance and efficiency at minimal vibration and noise levels. .. Fuel savings and reduced emission levels .. .. .. High...

FIXED PITCH Customization based on sturdy and high-efficiency designs The MAN Alpha FP Propeller designs effectively cover the full engine portfolio of MAN Diesel & Turbo. The propeller series are available in 3-, 4-, 5- and 6-bladed monoblock configurations casted in a single piece with hub and blades. Our standard material is specified as Ni-Al-Bronze, but other material alloys are available on request. For special high ice-class ship and propulsion applications tailored FP Propeller designs with Bolted Blades or Bolted Adjustable Blades can be offered. Bolted Blades for possible...

Propeller & Aft Ship Solutions  Page 14 | 15 FIXED PITCH Long-haul propulsion at lowest operational costs MAN Alpha FP Propellers are ideal for ships where highest efficiency and sturdy simplicity is of top priority. The obvious choice for ocean-going vessels with straight forward propulsion plants and operational patterns with long-haul sailing at service speeds at or around the propeller design and layout point, close to or spot on the maximum propulsive efficiency. Straightforward FPPs are, however, also specified for smaller yachts and workboats. .. Lowest TCO (Total Cost of Ownership)...

KAPPEL DESIGN Unique propeller blade design gains the highest efficiencies MAN Diesel & Turbo is offering the fuel-saving Kappel program for FP Propellers and for CP Propellers – meaning that the full range of MAN Alpha propellers is available with propeller blades of Kappel design. For retrofit upgrades numerous monoblock FP Propellers have been exchanged with Kappel, and also other makes of CP Propellers have successfully been fitted with the more efficient Kappel blades. Geometrically, the Kappel propeller design is characterized by non-planar lifting surfaces and blade geometry, by...

Propeller & Aft Ship Solutions  Page 18 | 19 KAPPEL DESIGN Kappel means superior propulsive efficiency Propellers with the Kappel blade designs are ideal for high-end ship designs where highest efficiency, upper energy classes, lowest consumptions and minimum environmental footprints are prioritized. The increased propulsive efficiency provides power reductions, savings via lower fuel consumption, reduced exhaust gas emissions or can be exploited as higher thrust for increased ship speed at a given engine output. .. Lowest fuel consumption and emission levels .. Maximized propeller...

Propeller & Aft Ship Solutions Page 20 I 21 Any emission harmful for the environment must be further reduced or * /in completely eliminated in the days ahead. The continued natural development in the direction of more green targets and restrictions will influence the maritime transportation and shipping industry. Future legislation will be driven to even stricter ‘clean shipping criteria’ by governments, non-governmental organizations, IMO, port authorities, ship owners, operators, customers and consumers - demanding actions to minimize the risk of pollution and prevent possible...

EFFICIENCY IMPROVING DEVICES Improving the flow to and from propellers MAN Diesel & Turbo masters a vast number of disciplines in relation to optimization of aft ship parameters and special installation requirements. The perfectioned layout and hydrodynamic propeller integration are always optimized with the ship’s hull and any flow-guiding Efficiency Improving Device (EID) and its position: .. Placed before the propeller Pre-swirl and wake equalizing ducts, pre-swirl fins or vortex generators A propeller nozzle, a fairing cone, or propeller hub cap fins can be deployed ..
