2 ME Service Experience: Danish Shipowners May 2017 Cylinder Condition General ME Update ME-GI and ME-GIE Remote Update of ME Engines < 2 >

3 Cold Corrosion Measures Jacket Cooling Bypass Basic Rating Dependent Cylinder Liner Load Dependent Cylinder Liner Cooling Water System Alpha Lubricator Mk. II High BN Cylinder Oils Oil distribution < 3 >

4 G80MEC 9.5 Cylinder Condition During running in: First inspection 1000 R/H Piston rings < 4 >

5 G80MEC 9.5 Cylinder Condition During running in: First inspection 1000 R/H Liners < 5 >

6 G80MEC 9.5 Cylinder Condition Condition after running in Piston rings R/H < 6 >

7 10L TSP Accumulators 10 failures reported Warning letter issued immediately Root cause: too sharp thread root Cross section of the lower shell Initiation point Crack < 7 >

8 TSP Accumulators Correction actions Design correction by TSP FEM validation by MDT MDT assistance during testing MDT supports QA/QC of production All 4856 pcs TSP 10L accumulators are being exchanged, around 4130 pcs are exchanged presently < 8 >

9 MPC/MPC10 Orion case < 9 >

10 MPC/MPC10 Orion case Case story Problem: Increased failure rates from one MPC/MPC10 manufacturer Data collection: Investigations and auditing Root cause: Fluxing and soldering processes affected Corrective actions: Temporary production stop. Changes in production process and QA/QC Verification: > 4000 units produced return rate ~ 1% < 10 >

11 EC MOP Sticky Touch Issue Issue: Touch pointer sticks Root cause: Failure of glass plate separation Corrective actions: Improved bonding Preassembly tests Verification: 0.5 % to 1.4 % failure rates after corrective actions < 11 >

12 ELFI / ELVA / FIVA Status: Sandwich filter has nearly eliminated shop test / sea trial problems. Super fine filter introduced for new orders from primo 2015 < 12 >

13 Inductive Sensors For fuel booster and exhaust valve position Claim rates are relatively low (<1.5%) Our work continue to reduce to target of 0.5 % or better. Sensor specification tightened with more strict reliability, environmental and dynamic characteristics demands. More strict approval procedure. < 13 >

14 ME-V Variable exhaust valve timing for ME-B9.3 Hydraulic push rod...extended by adding hydraulic oil Timing unit New short cam 5 g/kwh Previous cam Load [%] < 14 >

15 ME-V G/S50ME-B9.3 - improved design of ME-V timing piston Oil supply groove Previous version New version < 15 >

16 Worlds First ME-GI Engined Vessel NASSCO, USA, 8L70ME-GI & 3 x 9L28/32DF US shipyard NASSCO delivers world's first LNG powered container ship Big News Network.com - Sunday 18th October, 2015 < 16 >

17 8L70ME-C8.2-GI-TII, Service hrs 3685 Fuel in use Gas or Distillate Deposit control satisfactory, wear very low as Alu-coat still present after 3700 hrs Liner surface very good Sludge residuals in scavenge box is at very low level Deposit control by PC-ring is effective as deposits is not touching the liner < 17 >

31 ME-GI - Service Experience In case of a gas shut down caused by the following alarms. Cyl x: Expansion Pressure Too Low. Cyl x: Pgas Drop Test Failure Cyl x: Pgas Sensor Test Failure. Cyl x: Pgas Channel Curve Fit. Cyl x: Pgas Range Failure. 1. Make a manually Cyl. Events. 2. Make sure that no pressure fluctuations takes place in the gas channel. 3. Reset cylinder in block status. < 31 >
