Diesel Engine Condition Monitoring Due to Different Operation Areas
When a ship is design and developed, its engines are installed accordingly the environment conditions in a designated operation area and the owner requisites. Sometimes they are not design and adapted to sail in all seawaters temperatures. This implies that in some cases the engines power output cannot be the same for the safety of it. If an engine was conceived to operate on 16 ℃ of seawater temperature, when it navigates on a 36 ℃ sea, in some engines the power must be limited to not initiate major damage. Due the fact, in this study a diesel engine will be monitored with online data collection and statistical treatment. The statistic treatment will be done with the modified EWMA control charts. With the engine, operating on a range of seawater temperatures from 16 ℃ to 36 ℃, the auxiliary systems must be flexible due to ship performance with the aim of maintain it.
