MAN Diesel SE recently held a
small celebration at its works in Augsburg, Germany
. The event marked the start of acceptance testing of the final
engine of eight ordered by shipowner Harren & Partner of Bremen
, Germany, for a series of eight 16,500 DWT oil products
and chemicals tankers being
built at the Chinese Jiangnan Shipyard. As well as representatives from the shipowners, delegates from investors in the ships also participated at the celebration.
Of the eight vessels ordered by Harren & Partner, six were delivered in the period between November 2004 and November 2006 with the final two scheduled for handover later in 2007. In detail, the tankers have a liquid cargo capacity of 19,500 cubic metres, an overall length of 144 metres, a beam of 23 metres and an 8.4 metre draught.
On the propulsion side, the tankers feature a single six cylinder inline version of the 48/60B heavy fuel main
engine. Rated 6,300 kW at 500 rpm, the 6L 48/60B engine transmits propulsion power to a single MAN
CP propeller via a Renk reduction gear.
Built to Ice Class 1A, the vessels also feature a takehome
device whereby the 1500 kW A van Kaick shaft
generator on the reduction gear can act as a motor, drawing electrical power from the ship’s auxiliary engines.
MAN Diesel notes that the eight engines were among the first examples sold of the further developed “B” version of
its well-proven type 48/60 diesel, featuring enhanced fuel
consumption and reduced emissions among other improvements.
