Case study: Excessive fuel consumption on 60 % of the fleet

In 2020, a larger shipping company with MAN ME engines used PrimeServ Assist and detected an issue with one of its ships.

 

What PrimeServ Assist disovered...

The algorithm and analysis done by the remote operation center experts have shown the following:

• Air cooler: fouling detected
• Air cooler: temperature settings wrong
• T/C performance: poor
• Exhaust gas backpressure: too high
• Vessel hull: fouling detected 

Thus, the engine tuning was not optimzed.

 

... what actions the Remote Operations Center experts adviced to take...

The algorithm and analysis done by the remote operation center experts have shown the following:

• Clean the T/C
• Adjust air cooler temperature to optimum levels
• Clean the hull
• Observe the exhaust gas backpressure more closely

 

... costs saved with PrimeServ Assist

Poor engine tuning on this ship caused overconsumption of fuel. Optimizing the engine saved approximately $ 28.000 in fuel costs. This discovery led to an inspection of the whole fleet, which uncovered that 60 % of the fleet had similar engine problems. In total, cost savings of as high as $ 500.000 were made possible with PrimeServ Assist. Furthermore, the guidance given by PrimeServ Assist maximized the lifetime of the fleet’s engines. These issues – if they had remained undetected – would have shortened the lifetime of all combustion chamber parts. Moreover, the cylinder conditions would have deteriorated rapidly without corrective steps.
