Author: Daniel G. Teleoaca – Marine Chief Engineer Marine engines are the unsung heroes of the shipping industry, tirelessly powering vessels across vast oceans and seas. However, these workhorses face a unique challenge when it comes to low-speed operation. Low speed operation can cause various problems for marine engines, such as increased fuel consumption, reduced…
I believe that many of you, have heard in the last couple of years about running the main engine at low load or slow steaming due increasing fuel price and lately due more stringent environmental regulations. The 2-stroke engines are designed and optimized for operation in the load range above 60 % CMCR, but is…
Operational experience has shown that 4 stroke engines operating heavy fuels being bunkered from various ports globally and low load operation of the engine tend to cause fouling of the turbocharger. The condition and cleanness of the turbine of an exhaust -gas turbocharger have a decisive influence on the efficiency, the performance of the combustion…
Every ship’s engine room is equipped with some kind of diesel engine and most big ships nowadays are powered by two-stroke diesel engines, although the usage of four-stroke engines for propulsion is increasing due to the flexibility in where they may be installed and the enhanced redundancy that a larger number of smaller engines can…
