In response to the market demand for very large CP propellers up to and beyond 30,000 kW and with diameters over eight meters, MAN Diesel is expanding its propeller portfolio to add two new, propeller hub-sizes – VBS2080 and VBS2240 (2080 mm and 2240 mm hub diameters respectively). These propeller sizes are typically destined for ConRo vessels, shuttle tankers and special vessels with high ice classes, and powered by MAN B&W two-stroke MC-C or ME-C main engines that directly drive a CP propeller. As the potential for improving propeller propulsive efficiency aft-ship optimization is far greater than that for improving diesel-engine fuel-oil economy, MAN Diesel has devoted more resources to its CP propeller program and associated aft-ship systems in recent years, with the aim of improving total propulsive efficiency by 8-10% within the next three to five years. Backed up by industry demand, MAN Diesel focuses on low environmental impact and optimal fuel-oil consumption. While these two factors can play against each other in diesel-engine design, they go hand-in-hand with propellers since an increase in propeller efficiency results in lower propulsion power and fewer emissions. Where the correct approach to the vessel-design process is taken and MAN Diesel are involved at an early stage in propeller and aft-ship optimization

Heavy shaft vibrations led a container shlp owner to call in FN Diving in Rotterdam for underwater repair of the propellor. The inspection of the propeller revealed a deformation on one of the blade tips due to impact damage, the blade was found bent up to a 70 degree angle towards pressure side, while the tip of the next blade was broken off. In cooperation with the Propeller manufacturer, FN Diving determined an in situ repair plan.
Benefits of fitting CLT propellers include fuel savings of around 10 percent while maintaining the same speed, according to Geneva-based shipowner Cargill International SA, which has recently released consumption figures for two of its Panamax bulk carriers. The 70,000 dwt Powhatan and Paiute had CLT propellers retrofitted in February and March 1998, after Cargill had already benefited from more than two years' first-hand experience of the CLT propeller concept developed by Madrid-based
Worldwide underwater ship maintenance specialists UMC International and Dutch based marine propeller repair specialists Maritime Propeller Repairs (MPR) have signed an agreement to cooperate for workshop and in-water propeller repairs.

More than 300 visitors attended the event, and all were very enthusiastic about the new joint service
From the desktop of Luis Velarde, courtesy Rice Propulsion A propeller is exposed to all sorts of attacks underwater, such as rusting and adhesions of the sea. It is the key piece of the ship’s propulsion system, and thus deserves special attention. The propeller is the element that allows the transformation of the mechanical energy of the engine into propulsion. A propeller in poor state is a disaster
