Do’s : 1. Ensure taking a work permit from the site in charge and conduct a Tool Box Talk. 2. All electrical jobs to be conducted by a certified electrician. 3. Ensure all the equipment is flameproof. 4. Equipment that operates in three-phase power should have double neutral earthing. 5. The use of an Earth-leakage circuit breaker is a must for all the equipment. 6. The current rating for all equipment should not be greater than 30Amps. 7. Ensure use of proper rating Direct On Line Motor Starter in individual machines. 8. Ensure use of proper armored cables for the main power connection. 9. If there are cable lying on the road crossings or pathways should be covered and concealed to protect them from physical damage. 10. Cables without any joints should be used at all times. 11. Cables should be laid above the ground to the maximum possible extend. 12. Electrical connections should be kept clean, dry, and tight at all times. 13. Ensure all power supplies

ASTM D943 commonly referred to as Turbine Oil. Oxidation Stability Test (TOST), is widely used in the lubrication industry to evaluate the oxidation stability. *Best Practices for Steam Turbine Lubrication: 1. Keep Oil Clean, Cool and Dry 2. Install High Capture Efficiency Breathers to your Oil Respective Oil Tanks 3. Monitor returning bearing oil temperature regularly 4. Maintain proper alignment 5. Inspect for signs of foami

A) BSI (British Standards) – BSI BS 489:1999 –  Specification For Turbine Lubricants. B) DIN (German Institute for Standardization DIN 51515-1, 51515-2 –  This document specifies minimum requirements for oils for high thermal stress (high-temperature service) in turbines. C) ABB (ABB Group) ABB G12106 -  Ultra-clean turbine oil, Long-life, Rust & Oxidation-inhibited circulating oil. D) ASTM International – ASTM D4304  – Define the properties of the mineral and synthetic oil-based turbine lubricating oils that are functionally interchangeable with existing oils of this type, are compatible with most existing machinery components, and with appropriate field maintenance, will maintain their functionality.

1. Steam Turbine Oil a) Good Demulsibility:  Means the ability to release water, This is important when the equipment is operating in humid climates or in a plant atmosphere that is wet or humid. b) Foam Suppression, and Air Release:  Foam is used whenever there is a possibility of liquid fire. The Foam will mix with water and then expand over the liquid that is on fire, cool the fire, and will finally suffocate it. c) Anti-rust protection:  Rustproofing is the prevention or delay of rusting. d) Anti-wear protection (Certain Cases) : Antiwear additives (AW additives) are lubricant components that chemically react with Oil to protect metal-to-metal contact between parts of gears. 2. Gas Turbine Oil a) Anti – Corrosion Protection:  Help protect the base oil from oxidation and the metal from damage by corrosive acids. b) Anti – Scuff (Certain Cases):  Anti-scuff additives are designed to react with the parent metal surfaces to provide protection under severe loa

A) Oxidation Stability  – Oxidation stability is a chemical reaction that occurs with a combination of the lubricant and oxygen. The rate of oxidation is accelerated by high temperatures, water, acids, and catalysts such as copper. The service life of a lubricant reduces with an increase in temperature. B) Viscosity Index -  The viscosity index (VI) is an arbitrary, unit-less measure of a fluids change in viscosity relative to temperature change. It is mostly used to characterise the viscosity-temperature behaviour of lubricating oils. The higher the VI, the more stable the viscosity remains over temperature fluctuations. C) Filterability  - Capable of being filtered or separated by filtering. D) Low Sludging Formation Tendency  – Having low sludge formation tendency.

Place of Operation:  RHIP, Salalah, Oman Date of Execution:  December-2018 to April-2019 Criticality:  High Background :  Prior to Minimac being involved in the project, in August 2018, as a part of the pre-commissioning activity, flushing of 14 compressors and heat exchangers (ACHE, Picture 2) was performed and completed by a service provider. But soon after in the month of October, during the commissioning of the compressor, large debris deposits were found getting generated and collected in the in-line lube oil filter. The debris consisted of silica, metal shaving, and a lot of chunky particles. The commissioning activity was immediately stalled, leading to a threat to the project timeline and subsequent financial loss for the EPC company and the Operating company - PDO. Problem Statement :  Large particle contamination detection in the inline filters of all heat exchangers and compressors during the commissioning stage, even though flushing was completed as a part of the

This article aims to summaries how to read and understand the label on an oil can. That’s because brand and specification if chosen correctly, will affect the machine’s service life, reliability, ongoing maintenance costs, and help ensure the safety of all those working around. OEMs, oil marketers, additive companies, and testing laboratories work together to establish oil performance requirements, test methods, and limits for the various classifications and testing processes. The system includes a formal licensing agreement executed by lubricant suppliers with API. Through this program, API has standardized the labeling of engine oils by adopting the donut logo (Figure 1). The logo was designed to be placed in a prominent position on a variety of lubricant containers. API – American Petroleum Institute:  The American Petroleum Institute (API) administers the licensing and certification of engine oils through a system that meets the warranty, maintenance, a
