🔧 Komponenten & Aufbau 16

Turbocharger Unit (ABB/MHI/Napier) ABB Turbocharging

ABB A265-L Turbocharger

common failures: ['Turbine blade erosion (less on gas mode)', 'Bearing failure', 'Compressor surge at low-load gas mode', 'Nozzle ring thermal fatigue']

source family: X-DF

WIN-GD Common Rail Unit

common failures: ['Fuel rail pressure fluctuation', 'Injection control valve (ICV) stiction', 'High-pressure accumulator fatigue', 'Rail pipe joint leakage']

source family: X-DF

💡 Rail pressure ~1000 bar (fuel), ~200 bar (servo oil). Monitor rail pressure stability.

Lead time: 16 Wo.

Dual-Fuel System (Gas Mode) WIN-GD

WIN-GD X-DF Gas Admission System

common failures: ['Gas admission valve (GAV) seal leakage', 'Prechamber fouling', 'Gas/diesel mode changeover failure', 'Methane slip at low load']

source family: X-DF

💡 Gas admission at 10-16 bar via scavenge ports. Pre-chamber with diesel pilot. Monitor methane slip.

Lead time: 12 Wo.

Engine Control Unit (ECU / ECS) WIN-GD / ABB

WIN-GD WiDE Engine Control System

common failures: ['Redundancy switchover failure', 'CAN bus communication loss', 'Cylinder-individual timing deviation', 'Software version mismatch across units']

source family: X-DF

💡 WiDE = Wartsila Intelligent Diesel Engine. Dual-redundant. iCER optimization requires latest firmware.

Lead time: 8 Wo.

Fuel Valve (Injector) WIN-GD

WIN-GD X-DF Fuel Valve (diesel + pilot)

common failures: ['Pilot nozzle clogging (gas mode soot)', 'Main nozzle erosion (diesel mode)', 'Needle valve seat wear', 'Fuel leak at high-pressure connection']

source family: X-DF

💡 Pilot injector critical for gas mode ignition. Inspect pilot nozzle at 4,000 hrs. Main valve at 8,000 hrs.

Lead time: 6 Wo.

Exhaust Valve (& Valve Seat) WIN-GD

WIN-GD Exhaust Valve (X-DF)

common failures: ['Hot corrosion on diesel mode (vanadium attack)', 'Valve rotation failure (Rotocap)', 'Stem guide wear', 'Seat insert loosening']

source family: X-DF

💡 Gas mode extends valve life significantly (less hot corrosion). Overhaul at 16,000 hrs (gas-only: 24,000 hrs).

Lead time: 10 Wo.

Cylinder Liner WIN-GD

WIN-GD X-DF Cylinder Liner

common failures: ['Liner wear (reduced in gas mode)', 'Gas port erosion (dual-fuel specific)', 'Cold corrosion at low load diesel mode', 'Scuffing from CLO under-dosage']

source family: X-DF

💡 Gas ports machined into liner — inspect for erosion. Wear rate significantly lower in gas mode.

Lead time: 16 Wo.

FGSS (Fuel Gas Supply System - LNG/Methanol) TGE Marine / Wartsila Gas Solutions

FGSS LNG Supply Module (ME-GI type HP / X-DF type LP)

common failures: ['BOG compressor trip', 'Gas valve train leakage', 'Double-wall pipe integrity alarm', 'Master gas valve (MGV) failure to close', 'Inert gas system malfunction']

source family: X-DF

💡 LP-FGSS for X-DF (6-16 bar). Mandatory gas detection in duct space. Emergency shutdown drill monthly.

Lead time: 26 Wo.

Piston Crown WIN-GD

WIN-GD X-DF Piston Crown

common failures: ['Crown thermal fatigue (less on gas mode)', 'Cooling bore blockage', 'Crown edge erosion']

source family: X-DF

💡 Gas mode reduces thermal loading. Inspect at 16,000-24,000 hrs. Extended intervals possible in gas-only service.

Lead time: 14 Wo.

Hydraulic Power Supply (HPS) WIN-GD

WIN-GD Flex HPS (Common Rail Servo Oil)

common failures: ['Servo oil pump wear', 'Accumulator precharge loss', 'Servo oil contamination', 'Rail pressure instability']

source family: X-DF

💡 Servo oil system at ~200 bar. Filter changes every 4,000 hrs. Use approved servo oil only.

Lead time: 14 Wo.

Alpha Lubricator Control WIN-GD / Hans Jensen Lubricators

WIN-GD Pulse Lubrication System

common failures: ['Lubricator quill blockage', 'Timing valve failure', 'Feed rate sensor drift', 'CLO supply pump failure']

source family: X-DF

💡 Pulse lubrication for accurate CLO timing. Feed rate adjustable 0.5-1.0 g/kWh. Lower feed on gas mode.

Lead time: 6 Wo.

Scavenge Air Cooler WIN-GD / Alfa Laval

WIN-GD SAC (Plate/Shell-and-tube)

common failures: ['Air side fouling', 'Water side corrosion', 'Condensate drain choke', 'Tube leakage']

source family: X-DF

💡 Cleaner in gas mode — extended cleaning intervals. Monitor charge air temperature after cooler.

Lead time: 14 Wo.

Governor (Electronic/Woodward) Woodward

Woodward 723PLUS / WIN-GD Integrated Governor

common failures: ['Speed oscillation during mode changeover', 'Actuator hunting', 'Load sharing instability (dual-fuel transient)']

source family: X-DF

💡 Integrated with WiDE. Gas/diesel mode switching requires governor parameter set change.

Lead time: 4 Wo.

Crankcase Oil Mist Detector GEA / Schaller Automation

GEA Westfalia OMD / Schaller VN215+

common failures: ['Sensor window fouling', 'Sample extraction fan failure', 'False alarm from crankcase ventilation change in gas mode']

source family: X-DF
