An example which Marorka identified recently involved a main engine lube oil pump on board a capesize bulk carrier. The pump was running continuously, regardless of the ship’s operational state. It was driven by a 180kW motor with a daily fuel and OPEX cost of approximately USD 400.
The pump ran constantly while the ship was at anchor, even though the main engine was not running. Further analysis revealed that this was not an isolated case. The ME LO pump had been running for 85 days during one calendar year. The associated fuel and OPEX costs amounted to USD 34,000.
In addition to unnecessary consumption, the pressure on a standstill turbocharger without air pressure elevates the risk of damage to the TC. An event of this nature can have a major impact on the ship’s operation, especially if costly repairs are necessary.
Marorka specialists presented their findings to the ship’s operators, who updated work procedures and protocols throughout their entire fleet, leading to substantial savings.
