How the “LLF” condition monitoring technique can improve manufactured product profitability

Das, S., Bahrain Petroleum Co. (Bapco)

Technological advances have allowed predictive maintenance (i.e., condition-based maintenance) to overtake preventive maintenance in plant operations. “Look, listen and feel (LLF)” is a condition monitoring technique that improves the reliability of equipment and machinery in manifolds.

Redesign, simplify and demonstrate facts

Vila Forteza, M., Repsol SA

The Petronor oil refinery is located in northeastern Spain. Recently, the facility converted its last rolling element-equipped machine from liquid oil lubrication to pure (“dry-sump”) oil mist.

Analyzing axial cooling fans’ high noise, vibration and failures

Allah, W. K., Saudi Aramco

Shipping pumps with 1,800 hp are equipped with five cooling fans that cool the oil going to the lube oil pumps to lubricate the bearings.

Equipment critical analysis: The need for an effective maintenance program

Zardynezhad, S., Toyo Engineering Canada Ltd.

Oil refineries and large petrochemical plants contain thousands of pieces of process and utilities equipment that are subject to wear, erosion, deterioration, aging, etc., resulting in increasing breakdowns and outages. Imagine being a maintenance engineer and receiving 50 work orders during an overhaul with a limited budget, time, labor, spare parts, tools, machines, etc. How does that engineer prioritize the work?

Root cause analysis on bearing failure on an induced draft fan

Allah, W. K., Saudi Aramco

This case study aims to provide the root cause analysis behind bearing failure of an induced (ID) fan at a new refinery startup in 2015.

Implement proactive asset management techniques

Natarelli, J., T.A. Cook Consultants Inc.

The drop in crude oil prices since 2014 has impacted both upstream producers and downstream players. Upstream producers—those responsible for exploration, drilling and production—were the first to feel the effects. While refining margins benefitted from the drop in crude oil pricing, they began to suffer when record surpluses of gasoline and diesel flooded the market a year later.

Buyer beware: Are diamond-coated seal faces the solution to dry running?

Seymour, M., Engineering & Quality Systems

A scientific study was undertaken to evaluate the performance, under dry running conditions, of two types of diamond coatings applied to silicon carbide faces of mechanical seals.
