Exam Question

Periodical Lub oil analysis, its correct interpretation and corrective measures are of critical significance for the maintenance of marine machineries. With reference to the modern analysis techniques employed for the condition analysis of LO, discuss the following:

(a) Elemental (Spectrometric) Analysis

(b) Fourier Transform Infrared (FTIR) Spectroscopy

(d) Base Number Vs Acid Number

Reference Answer

A comprehensive lubricating oil analysis program is fundamental to Condition Based Maintenance (CBM) for marine machinery. It provides critical insight into the health of both the lubricant and the machinery, enabling proactive maintenance and preventing catastrophic failures. The following modern analysis techniques are pivotal in this process:
