The layout of ship propellers is a balancing act between optimal power conversion and the avoidance of unwanted cavitation effects, which can result in damage to the propeller structure and higher noise levels. MAN Diesel & Turbo in Frederikshavn, Denmark, is using the computational fluid dynamics (CFD) simulation solution STAR-CCM+ from Siemens PLM Software to model cavitation and optimize ship propellers. Two mid-size container ships of 8,500 TEU – CSCL Europe and CSCL America – will be upgraded by retrofitting a efficient Kappel propeller.

The new Reckmann MF series of manual furling systems will replace the RS2000, which has been in production since 1990 and Advanced Rigging & Hydraulics have exclusivity as dealers for Reckmann in the UK. Designed to be retro-fittedmore seamlessly with existing forestay systems, the new Reckmann MF Furling System will be available this spring with both above deck and under deck versions suitable for both rod and wire forestays. It is an elegant design with first class workmanship, using the very best materials available. All axle elements as well as the drum guard and toggle are manufactured with precisely specified stainless steel alloys. These combined with the high-­‐strength bronze length adjuster and the light rigid plastic drum, result in a highly functional and durable system.

Lloyd's Register is offering training courses in the properties of marine materials, welding techniques and non destructive examination (NDE), some of the cornerstones of ship construction, repair and maintenance. The course, Basic Principles of Materials, Welding and NDE for Existing Ships, has been designed for superintendents, ship-managers and the technical staff who are responsible for keeping their ships safe and operating efficiently. "Most materials and welding courses do not cover the specific problems encountered by marine superintendents and engineers. This course has been developed and tested with marine clients who have faced real difficulties and is ideal for developing the knowledge of superintendents and engineers…

The Russian government will pour $250m into modernizing the production of special steel alloys. The lack of modern technology is holding back the production of ultra-strong alloys and steel currently used in aerospace and shipbuilding, Russia Today said. Russian Prime Minister Viktor Zubkov launched the first modern smelting furnace in the region. The government plans to commission another three furnaces by the end of the decade.  Russian officials say it's currently a low-profit, niche product, but that could change. The government also promises to provide state-backed credits for steel producers to buy new equipment. Source:  Today
