MAN B&W Diesel has been part of the propeller business from the very beginning. The first Alpha Controllable Pitch Propeller was produced in 1902 and patented in 1903. In the meantime, more than 6500 MAN B&W propellers have gone into service. A great variety of CP Propellers with Propulsion Control Systems for all applications up to to-day’s 30 000 kW range. On 3 December 1903 the CP Propeller patent came into force, and the past CPP-century was celebrated with a propeller conference at MAN B&W Diesel in Denmark exactly on the anniversary day 3 December 2003. A conference packed with propeller and propulsion knowledge Invited guests from shipyards, owners, ship consultants and design organisations - together with technical editors from the major magazines, took benefit of the exchange of information and expert knowledge from a conference programme with MAN B&W speakers managing various business and design departments related to diesel pro-pulsion and CP Propellers. A versatile technical confer-ence with special focus on the following propeller and propulsion topics and paper titles: 1903-2003 - One Hundred Years with CP Propellers, Conference opening C Windelev, Senior Vice President, General Manager MAN B&W propellers and package solutions - by Mr K Borneman, Manager of Propulsion Sales Hydrodynamic design - by Mr J Ring Nielsen, Manager of Propulsion R&D Mechanical design and future trends - by Mr J Ring Nielsen, Manager of Propulsion R&D

MAN Diesel & Turbo’s PrimeServ retrofit team is to supply India's Great Eastern Shipping Company (GESCO) of Mumbai with an upgrade retrofit propeller for their tankship 'Jag Lavanya', a Samsung 2004- built 105,000 dwt crude oil carrier. Kappel fixed pitch propellers MAN Diesel & Turbo recently announced a strategic focus that added the Kappel design to its fixed-pitch propeller portfolio, both for newbuildings and as a retrofit solution to vessels already in service
The CLT propeller recently underwent real-world testing, which proved, according to its designer and manufacturer that the propeller can help to reduce or eliminate hull-induced vibrations and noise levels. Independent studies were conducted aboard Superfast Levante, which demonstrated that: the cavitation level developed on the CLT propeller blades is negligible from the ship's structural integrity point of view; vibration and noise levels are excellent in terms of comfort on board; and the
MACSEA offers an independent hull monitoring service designed to save fuel and reduce emissions by detecting hull fouling as early as possible. The new service, called Hull Medic, uses automatic onboard data acquisition to gather salient ship performance data and transmit it ashore for detailed analysis. Hull Medic will typically review 100,000’s of a ship’s data records per month, providing high-accuracy statistical analysis for earlier detection of hull fouling
By Leonardo Montoya, Rice Propulsion, in the January edition of MarineNews Yes, sometimes they sing: Some propellers in service produce a high-pitched noise, often referred to as “singing.” This sound typically is a clear harmonic tone much like a humming or a ringing wine glass. More of an annoyance than anything harmful, the causes of singing are not completely understood. Many theories have been put forward to account for the phenomenon of singing
In February John Crane-Lips transported one of the world's heaviest fixed pitch propellers from its premises in Drunen to 's-Hertogenbosch. This 6-bladed propeller has a diameter of 8.8 meters and a weight of 92.5 tons. The material of which the propeller is made is Cunial©, an alloy of copper, nickel and aluminum. Upon arrival in 's-Hertogenbosch the propeller was lifted with a large hoisting crane to put it on a barge and was then shipped to the port of Rotterdam
PBCF Aids Propulsion Efficiency Propeller Boss Cap Fins (PBCF) is a propeller enhancing device, which is designed to cut fuel consumption and exhaust gases by up to five percent while incurring no additional maintenance cost once installed. The unit, according to H. Yumoto Manager of PBCF Div. Mitsui O.S.K. Techno Trade, Ltd., is now operational on 720 ship worldwide. The PBCF rectifies the propeller hub vortex and recovers rotational energy otherwise lost in the propeller slip stream
The joint venture company set up by Wärtsilä and CSSC (China State Shipbuilding Corporation) in China to design, manufacture and deliver Fixed Pitch Propeller (FPP) packages has officially started operating at the beginning of June 2004. The new company, called Wärtsilä-CME Zhenjiang Propeller Co. Ltd, is 55%-owned by Wärtsilä and 45%-owned by Zhenjiang CME Co. Ltd (CME), the latter being a wholly owned subsidiary of the CSSC.
Spanish tuna vessel opts for fuel-efficient propulsion package. Based in Spain, the Pevasa Group recently ordered a complete propulsion system from MAN Diesel and Turbo for a new tuna vessel. The system is unique in that it comprises a package of three high-efficiency products, including a modern, medium-speed MAN 8L32/44CR engine with common-rail (CR) technology, a Renk RSVL-950 gear unit, and an innovative MAN Alpha VBS1100 CP propeller with Kappel propeller blade designs and rudder bulb
