Propulsion TCA44 completes
the range Revealed in January 2011 and weighing 1.970kg, the TCA44 recently underwent an extensive test programme on MAN Diesel & Turbo’s turbocharger test bed in Augsburg. The TCA44 completes MAN’s TCA
turbocharger range for two-stroke engines at its lower end. Stefan Mayr, project engineer respon- sible for the TCA44, said: “This new turbocharger has been specifically designed to meet the needs of small-bore, two-stroke engines and provides optimised turbocharging solutions for engines that exceed the capacity limits of the smaller TCR22 turbocharger.” Until now, the TCA55 with a small turbine and
compressor wheel has been used for such engines. The TCA44 is some 40% smaller and lighter than the TCA55, which suffered from its larger size. With the predicted development of the Chinese short-sea and coastal operation and the growing demand for small-bore, two-stroke engines. Demand for the TCA44 has been strong and MAN Diesel & Turbo has already taken in a significant number of orders from its two-stroke licensees. The company reports that serial deliver- ies will start in the second half of 2011.

Te TCA44 follows the principal design philosophy
of the TCA series, but with some major innovations that facilitate production, installation and mainte- nance, including: 45 steel turbine blades with new airfoil profile, the fixation of turbine blades by one retaining ring instead of 45 individual fixing-plates, oil supply and discharge integrated in turbocharger feet as integral part of the bearing casing, a new compressor-wheel profile, a simplified IRC design, a modified silencer. Some of these innovations, such as the turbine
blade fixation, will gradually be introduced to the other frame-sizes of the TCA family.

Ancillary equipment Cargotec to supply cruise ships
Cargotec is to supply MacGregor access equipment for two cruise ships for Meyer Werſt, scheduled for delivery in 2013 and 2014. The contract includes passenger doors, tender
platforms, shell doors and platforms for loading stores, bunkers and luggage, and for mooring operations, and the weight of the MacGregor equipment totals around 230tonnes per shipset. “Each ship will be provided with MacGregor
passenger access equipment which enables smooth and safe embarkation of passengers via the passen- ger entrance doors or embarkation platforms,” said Göran Hugon, Cargotec’s sales manager for passenger ship and RoRo systems. “Loading luggage, provisions and fuel, and discharging garbage, is efficiently handled with the numerous side shell doors, as are mooring operations. This order highlights the success of Cargotec’s strategy to re-enter the cruise ship market.” “Cargotec has a long experience in providing
innovative solutions based on proven technol- ogy. This, together with a close cooperation with Meyer Werft shipyard, made us successful in securing the order.”
