Description
Overview
Two Wärtsilä HFO oil cubes, each rated at 1539 kW.
Voltage: 11,000 volts.
Frequency: 50 Hz.
Speed: 1000 rpm.
Fuel: HFO/LFO.
Complete plant with auxiliary systems.
Units manufactured in 2009 but purchased directly from Wärtsilä at the end of 2019; brand new, never used equipment in excellent condition.
Wärtsilä performed an inspection approximately two months ago and found the plant in excellent condition.
