MAN & Diesel Turbo has delivered the 10,000th turbocharger from its TCR radial-type series. The TCR14 unit was produced for a 5L23/30H genset for Oldendorff Carriers, one of the world’s largest dry bulk shipping companies based in Lübeck, Germany.
The Jinling-built 38,000 dwt bulker is the second in a series of four vessels, all propelled with MAN two-stroke and auxiliary engines. Dirk Balthasar, MAN Diesel & Turbo vice president and head of turbocharger sales and promotion, said: “The information garnered from over 10,000 TCR turbochargers in the field gives us a huge insight into their overall performance. The TCR series was introduced in 2004, meaning that many of these turbochargers have run for over 10 years and have had a second major overhaul. We calculate our accumulated TCR service experience now as more than 200 million operating hours. We use this knowledge to constantly improve the TCR series.”
Mr Balthasar concluded: “This strategy can be seen to have paid dividends with this impressive sales milestone and the fact that TCR turbochargers enjoy broad support across the market and supercharge both MAN and non-MAN engine designs.”
Oldendorff’s newbuilding bulker also has a Tier II MAN B&W 5S50ME-B9.3 main propulsion engine, built by Yichang Marine Diesel Engine Co, and is optimised with a highly efficient TCR22, the largest radial-type turbocharger in the world.
Oldendorff Carriers is a specialist in spot markets, industrial contracts and offshore transshipment, and dry bulk logistics. It operates about 500 ships, both owned and chartered, that carry about 270 million tonnes of bulk and unitised cargo around the world per annum.
The MAN TCR turbocharger series was introduced in 2004 to replace the NR series, which has been in production for nearly 50 years, and to address the particular challenges of high, medium and low-speed engines. The MAN TCR is a completely new design that delivers greater efficiency, the lowest possible weight, reduced size and number of components, material optimisation, easier maintenance, and quicker response behaviour during acceleration.
Advanced materials ensure that the TCR series offers extended overhaul intervals, easier maintenance and longer lifetimes. MAN TCR turbochargers were designed to address the specific challenges faced by heavy fuel oil, marine diesel oil, biofuel and gas engines. Seven frame sizes are available for the entire engine power range, from 350kW to 7MW per turbocharger.
The TCR series can be equipped with a variable turbine area as an option to increase engine efficiency, as employed in most modern, two-stage turbocharging systems. Different options for flow parts and turbocharger casings enable a perfect fit with a variety of different applications and engine types.
