8 How we made the A200-L new new modified new October 2, 2014 Slide 8

9 Illustrations for constant output Same output A180-L35 A275-L -20% product cost -25% maintenance costs October 2, 2014 Slide 9

10 A200-L service concept Continuous high performance from dry-dock to dry-dock One intermediate visual inspection of key components Smart and compact design for easy maintenance Optimized features Integrated lubrication oil tank Integrated bearing design Improved labyrinths for minimum air blow-by and oil blow-by Improved compressor and turbine cleaning devices October 2, 2014 Slide 10

11 A200-L referances Large number of turbocharger A100-L units 400 A200-L units Ask for A200-L October 2, 2014 Slide 11

12 HPT for MAN engines Tunings for 2- stroke engines New vessels optimized for real operating conditions Slow steaming De-ratating Engine tunigns October 2, 2014 Slide 12

13 HPT for MAN engines Why engine tuning and what s that? Engine optimizing for lowest fuel consumption at a given intended load profile of the vessel. Optimized for high-load (90-100%) Optimized for part-load (70-90%) Optimized for low-load (0-70%) Engine adjustments with shims, timing, coolers, etc., Optimized ABB turbocharger specifications October 2, 2014 Slide 13

15 HPT for MAN engines How to tune an engine for part/low load? exhaust gas bypass (EGB) engine control tuning (ECT) for electronic engines only variable turbine geometry (VT) High Pressure Tuning (HPT) October 2, 2014 Slide 15

16 HPT for MAN engines The concept: Increased scavenging air pressure at SMCR ( bar) (two-stroke Miller timing) Results in higher scavenging air pressure at part and low-load, equal to EGB/VT tuning Scavenging air pressure October 2, 2014 Slide 16

19 HPT for MAN engines Benefits of HPT: Equal or better SFOC compared to VT or EGB VTG/ EGB not needed No investment No maintenance No breakdown Combined with all A200-L High charge pressure High volume flow Dual rating possible (part load + low load) Available on MAN electronic engines (ME) and exhaust valve control 29 engines delivered with HPT October 2, 2014 Slide 19
