Engines MAN Celebrate
Order Completion MAN Diesel SE recently held a small celebration at its factory in Augsburg, Germany to mark the start of acceptance testing of the final engine of eight ordered by shipowner Harren & Partner of Bremen, Germany. The engine is destined for one of a series of eight 16,500dwt oil products and chemicals tankers being built at the Chinese Jiangnan Shipyard. 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 19,500m3
,
an overall length of 144m, a beam of 23m and an 8.4m draught. Te tankers feature a single six cylinder inline
version of the 48/60B heavy fuel main engine. Rated 6300kW at 500rpm, the 6L 48/60B engine transmits propulsion power to a single MAN Diesel Alpha CP propeller via a Renk reduction gear. Built to Ice Class 1A, the vessels also feature a take-home device whereby the 1500kW A van Kaick shaſt 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. Commenting on the successful contract both
Peter Grönwoldt, managing director at Harren & Partner Ship Management and Wolfgang Volkens, fleet manager at Harren & Partner Ship Management stress the positive performance of MAN Diesel and its engines. “Safe and uninterrupted engine operation, long pre-planned overhauls and reliable partners help us to keep track of our operating expenses which are more and more under scrutiny these days.”

Wärtsilä and Stolt Tankers BV have signed an agreement for Wärtsilä to be the exclusive supplier of bilge water treatment units to the Stolt-Nielsen group. The agreement ensures that newbuildings, and retrofits of existing Stolt vessels, will be fitted with Wärtsilä Senitec M-series bilge water treatment units and Wärtsilä Senitec BilgeGuard bilge discharge monitoring systems. “We believe that continuous improvement
leads to lean, agile processes and excellence in general. Stolt strives to select partners who display a similar philosophy. We recognised the excellence of continuous improvement in the Senitec unit, which is clearly the market’s most evolved unit,” says Rob Scharff, general manager of purchasing and logistics at Stolt Tankers BV. The Wärtsilä Senitec M-series range encompasses
the M500, M1000 and M2500 bilge water treatment units, capable of treating 0.5 to 2.5m3
of oily water
per hour respectively. All units guarantee that the oil content in the treated water will be no more than 15 ppm (parts per million), with real case levels being below 1 ppm during continuous operation. Together with the Wärtsilä’s Solidpac add-on, the units will reduce the amount of bilge water for disposal ashore by as much as 95%, minimising the environmental impact and significantly lowering disposal costs.
