38 Maritime Reporter & Engineering News ? JULY 2013 A More Powerful Wärtsilä 34DF Wärtsilä introduced a more powerful version of its 34DF engine. Today the Wärtsilä 34DF is being mainly used in tugs, ferries, RoRo, RoPax and work-boats.The new and upgraded version of the Wärtsilä 34DF engine increases the efÞ ciency in both liquid and gas operat- ing modes and offers a power increase up to 500kw per cylinder. This increased output means that the Wärtsilä 34DF now covers a power range from 2.9 to 8 MW. In addition to the increase in power, fuel economy is also enhanced, especially when operating in liquid fuel mode. When operating in gas mode, the Wärtsilä 34DF engine is already com-pliant with IMO Tier III regulations without any secondary exhaust gas pu-riÞ cation systems. Also when fueled by gas, the SOx and CO2 emissions are no-tably reduced, and smokeless operation is attained. In liquid fuel oil mode, the Wärtsilä dual-fuel engines are fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention. GE to Equip Latest Hornbeck MPSVs GE to equip two multipurpose supply vessels at Eastern Shipbuilding Group. GE?s Power Conversion business was awarded a contract by the Eastern Ship-building Group in Panama City, Fla., to supply integrated diesel-electric power, propulsion and vessel control systems for two multipurpose supply vessels (MPSVs) with installed horsepower of 12,070 BHP (9,000 kW). Eastern will build the MPSVs for Hornbeck Off- shore Services of Covington, La. The new contract is for the Þ rst of two multi- purpose support vessels for the compa-ny. The vessel control systems include Class 2 Dynamic Positioning (DP), power management, alarm and moni-toring, vessel control and an integrated bridge system comprising navigation and communication equipment.

First MAN TCR12 Turbocharger Built in China MAN Turbocharger China unveils the Þ rst TCR12 turbocharger completely as- sembled at its Changzhou factory, con Þ rming the company?s strategy of localizing its turbocharger production in China. Initially acting as an assembly workshop for axial turbochargers, MAN subsequently localized component production over the years. In time, the Shanghai factory became too small and, in 2011, the turbocharger workshop was moved to the existing plant in Changzhou. NEWSPRODUCTSABB Breakthrough for Enhanced Reliability Drillship ABB won a landmark offshore marine industry con- tract covering electrical power and propulsion sys-tems onboard a DP class 3 Drill Ship to be conferred with ?Enhanced Reliability? and DYNPOS AUTRO notation from DNV. The contract covers installations onboard a ?BT-UDS? dynamic positioned ultra-deep water drill ship ordered by Sigma Drilling, the joint venture between Norway?s Skeie Technology and Houston-based Vantage Drilling, from STX Offshore & Shipbuilding. The vessel, to be built at South Ko- rea?s STX Jinhae yard, is scheduled for delivery in the second half of 2015. The new DYNPOS ER class notation for Enhanced Reliability from DNV recognizes advances made in ß exibility, redundancy and fuel-ef Þ ciency in the structuring of DP systems. The notation covers con- nected power systems with standby start-up capabili-ties in speciÞ c conditions and the seamless and re- dundant change-over of generators and thrusters, via closed bus ties. To meet DYNPOS ER and the DYNPOS AUTRO with closed ring requirements, the Sigma Drilling ship will feature ABB?s most advanced protection de- vices; fast bus communications based on IEC 61850 standards and integrated blackout prevention func-tions. DYNPOS ER has speciÞ c requirements for operational ß exibility and the safe operation of the power and thruster plant on board.ABB is supplying a comprehensive package of power and propulsion plant and preventive maintenance sys-tems onboard, including generator sets, switchboards, thruster motors, thruster drives, the drilling drive sys-tems, Diesel Generator Monitoring System (DGMS) and Remote Diagnostic System (RDS).The BT-UDS is a new design of drillship which has been developed by Bassoe Technology. Capable of drilling wells down to 40,000ft (12,190m) in water depths of up to 12,000ft (3650m), the 232m long, 38m wide vessel will have a payload capacity of 25,000 tons. Six azimuthing thrusters combined with the Bassoe-developed hull form will provide a transit speed up to 16 knots.(L to R): Ralf Großhauser ?
