New PowerTech 9.0L and 13.5L Tier 3 propulsion and generator-drive en- gines join the previously announced 4.5L and 6.8L Tier 3 models. The PowerTech 6090AFM85, PowerTech 6090SFM85, PowerTech 6135AFM85 and PowerTech 6135SFM85 propulsion and generator-drive engines are the latest additions to the JDPS Tier 3 lineup. JDPS added two new 9.0L models to its lineup of Tier 3 marine engines: the PowerTech 6090AFM85 and PowerTech 6090SFM85 propulsion and generator-drive engines. The PowerTech 6090AFM85 is an air- to-coolant aftercooled version of the John Deere 9.0L engine. It is available in four different propulsion ratings from 213-317 kW (285-425 hp); gen-set ratings include 222 kW (297 hp) at 1,800 rpm for 60 Hz and 195 kW (261 hp) at 1,500 rpm for 50 Hz.The PowerTech 6090SFM85 is a turbocharged and air-to-seawater aftercooled engine. The model is available in Þ ve different propulsion ratings from 242-410 kW (325-550hp); gen-drive ratings include 222 kW (298 hp) at 1,500 rpm for 50 Hz and 278 kW (373 hp) at 1,800 rpm for 60 Hz. JDPS 13.5L Tier 3 propulsion and generator-drive engines include the Pow- erTech 6135AFM85 and PowerTech 6135SFM85. The PowerTech 6135AFM85 is the largest John Deere air-to-coolant aftercooled engine, and is available in four different propulsion ratings from 272-429 kW (365-575hp); genset ratings in- clude 334 kW (448hp) at 1,800 rpm for 60 Hz and 278 kW (373 hp) at 1,500 rpm for 50 Hz. The PowerTech 6135SFM85 is the most powerful engine produced by John Deere. The turbocharged and air-to-seawater aftercooled engine features six cylinders and electronic controls, providing high torque at low speeds. The 6135SFM85 model is available in Þ ve different propulsion ratings from 317-559 kW (425-750 hp); gen-drive ratings include 416 kW (558 hp) at 1,800 rpm for 60 Hz and 334 kW (448 hp) at 1,500 rpm for 50 Hz. www.johndeere.com/jdpower John Deere Tier 3 Engine Line Up Photo: John Deere Power Systems 6090SFM856135SFM85Hornbeck Offshore will employ GE Power Conversion?s latest generation DP technology for its four new multipurpose supply vessels (MPSVs). In their role as MPSVs, they can operate as either a subsea construction vessel capable of performing complex subsea construction operations or as a resupply and support vessel to ultra deepwater drilling in the Gulf of Mexico, or anywhere else in the world as required by their charterers. ?The DP solution and its user interface is the heart of a ship?s positioning system. When we can continue to work with a company that knows us, has supplied us with systems in the past and, with our input, can supply us with a next generation system we can rely on, it remarkably enhances our mission to provide value-added business solutions for our own customers,? said Carl G. Annessa, EVP and COO at Hornbeck Offshore. ?By using GE?s solution, we gain ef Þ ciency and ß exibility thanks to a commonality of systems, as well as access to a global team of experts.?GE will power, propel and position the new ships by delivering the integrated diesel-electric system including generators, propulsion and thruster drives, motors, switchboards, LV distribution, transformers, Class 2 DP, power management, alarm and monitor- ing, vessel control and an integrated bridge system comprising a comprehensive navigation and communications suite including radars, ECDIS, GMDSS and a full suite of internal and external communications systems. GE is also equipping Hornbeck?s series of 10 PSVs. GE Power ConversionTo Provide Hornbeck Vessels DP MR #11 (42-49).indd 49MR #11 (42-49).indd 4911/12/2013 10:59:58 AM11/12/2013 10:59:58 AM
