Service concept for TPL-B two-stroke turbochargers

Long distance runners:36,000 running hours,“drydock-to-drydock”

TPL-B bearings go the distance

 A serviceconcept introduced by ABB Turbocharging for TPL-B

turbochargers lets ship operators reduce the frequency of

turbocharger bearing inspections between scheduled over-hauls. The bearings can now stay in place for 36,000 running

hours, or from “drydock to drydock.”

Designed to last

 Typical of ABB Turbocharging Original Parts, the TPL-B

bearing assembly’s proven high reliability is due to its unique,

high technology design. The main axial bearing is a free-

floating thrust disc with profiles on both sides, rotating at

about half the rotor speed. This ensures thick oil films, offering

extra-high resistance to wear. Disc wear is also reduced by

an extremely hard coating, while a squeeze oil film damper

ensures exact centring of the radial bearing bushes.

Long-distance runners

 ABB Turbocharging introduced the TPL-B turbocharger series

for low-speed 2-stroke diesel engines in 1999, mainly for

marine applications. The engine output range covered by the

 TPL-B series is 3,000 to 28,000 kW per turbocharger.

 TPL-B turbochargers were designed from the outset for easy

maintenance and service. Field experience with tens of thou-

sands of ABB turbochargers with plain bearings went into their

development. ABB’s engineers were thus able to present tothe marine world a 2-stroke turbocharger with bearings able to

run for some 36,000 hours before being exchanged.

“Turbo pit stop”

 This service also offers ABB TPL-B turbocharger end users

the cost benefits of a service-friendly, faster intermediate

inspection at 18,000 running hours. The standard 36,000 hour

overhaul remains the same; no extra work has to be carried

out.

 This innovation from ABB is a major benef it for shipowners.

Just a short port stay is all that is now needed for the TPL-Bintermediate inspection. With this “turbo pit-stop,” ABB sets

the industry benchmark – field-proven 36,000 hour bearing

exchange intervals for the TPL-B, allowing the 2-stroke turbo-

chargers to be run with the same bearings from “drydock to

drydock.”
