| dc.description.abstract | Lubricating oil systems are vital to operation, long-term reliability, and availability of turbomachinery trains (or strings) which are strategic and expensive components of industrial plants. Sometimes, the entities that specify machinery strings for their projects do not completely specify the required features of oil systems. For example, API 614 datasheets that contain only minimum information, such as the type of lube oil pumps and their drivers, the type of coolers, and the required inspection and testing, creates an inadequate basis for oil system design, and time is wasted in obtaining missing or incomplete details. In some situations, the purchasers change or add scope much later into the design, which can negatively impact cost and delivery schedules. Design deficiencies in lubricating oil system results in underperformance and affects reliability, and operability not only of the oil system but also the served equipment string or train. The scope and configuration of the lubricating oil system for a stated application should be jointly evaluated by the vendor having the unit responsibility, the oil system designer, and the specifying machinery engineer. All components of the oil system should be discussed, and the design basis finalized by these parties as much as practically possible before awarding the purchase order. | |
