Turbocharger · Turbochargers
The ABB Marine A200-M is a marine exhaust-gas turbocharger for internal-combustion engine service. It is mounted on or adjacent to the engine exhaust and charge-air system and uses exhaust-gas energy to drive a compressor that supplies pressurized combustion air. Reliable operation depends on clean gas and air paths, sound bearings, correct lubrication where applicable, intact sealing arrangements and stable engine operating conditions. Turbocharger condition directly affects air delivery, exhaust temperature, smoke, engine response and available power. The model designation separates this unit from neighbouring turbocharger sizes and frame variants, but wheel dimensions, speed limits, clearances, matching data and overhaul criteria must be taken from the exact serial-number documentation. For all balancing, clearance, tightening and replacement limits, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Trend boost pressure, exhaust temperatures, turbocharger speed where monitored, vibration and abnormal noise against normal engine load. Inspect air filters, compressor condition, gas-side cleanliness, drains, bearings, lubrication connections and casing for leakage or damage. Cleaning and rotor work must follow the manufacturer method to avoid imbalance or blade damage. A surveyor will look for maintenance records, evidence of rotor contact or oil leakage, secure guards and correct response during engine trials. Refer to the manufacturer documentation for exact clearances, limits and overhaul requirements.
Carry approved filters, seals, gaskets, fastening and locking items, bearing or service kits where permitted for onboard maintenance, and cleaning consumables appropriate to the installed unit. Major rotating components must be ordered and handled as matched, manufacturer-approved parts for the exact turbocharger serial number.
