Natural Gas Power Plant 58.3 MW / 50 Hz Wartsila 6 × 20V34SG with
Auxiliaries
This power plant was originally built by Wärtsilä in 2011 as a
turnkey project without heat recovery boilers. Later, the owner added
4 × 3.7 MW / 18 bar exhaust gas steam boilers with auxiliaries, which
are available as optional items.
The plant was in operation until 2017, accumulating approx 21000
operating hours per engine. All scheduled services were performed by
Wärtsilä Service, including the 16,000-hour and 24,000-hour
services, completed just prior to dismantling in 2021. This ensures
that the gensets are fully maintained and do not require servicing
before re-commissioning.
After shutdown, all equipment—including cables, pipes, and OEM
modules—was professionally dismantled, tested, packed for
transportation, and placed in storage. Control cabinets are stored in
a heated warehouse, while other equipment is kept in standard cold
storage.
The engines are controlled by the modern Wärtsilä UNIC engine
control system.
