Due to time limitations and higher operational flexibility modularization has taken relevance at the time of conception of new projects, any inspiration to modularize needs to align with project needs.

A pressure seal globe valve consists of several key components, each with a specific function to ensure the valve operates efficiently under high-pressure conditions. Working Principle: When the handwheel or actuator is turned, it rotates the stem, which moves the disc up or down. In the open position, the disc is lifted away from the seat, allowing fluid to pass through. In the closed position, the disc presses against the seat, preventing fluid flow. The pressure seal bonnet design ensures that the seal between the bonnet and body becomes tighter as the internal pressure increases, enhancing leak prevention. Applications: Pressure seal globe valves are widely used in industries where high pressure and temperature conditions are prevalent, such as: - Power plants (steam systems) - Oil and gas(refineries and pipelines) - Chemical processing (handling corrosive and toxic fluids) - Petrochemical industries Understanding these components and their functions is crucial for the proper selection, operation, and maintenance of pressure seal globe valves in various industrial applications. #psgbv #gbv #Valves #PressureSeal

🚦Red Hot Exhaust Manifold - Check🔥 Red hot exhaust manifold is present when the engine is operating on full load.. Exhaust Manifold can #experience red hot when - High exhaust temperature - Weak material strength as result of age. When engine operating programmed parameters are correct, red hot🔥 exhaust can be #ignored. The hotness is present when the Air fuel ratio and setting & adjustment is incorrect. Caterpillar #computerized electronic engines measure the volume of engine boost pressure to enable the amount of fuel to combustion chamber. When excess fuel finds its way to the combustion chamber can raise the exhaust temperature and present Redness. Low boost pressure can enable red hot🔥 exhaust when the engine is operating at fuel load. Engines operating above #load capacity for a long period of time can present red hot.. Caterpillar Electronic Technician(ET) computer is used to perform insight to the engine system, check and adjust programmed parameters. Engine total running hours/age made it easy to enable repair options in addition of information, follow Ayo O.

Overhauling of GE Steam Turbine, air compressor driver, of rated power 8020 HP A complete overhaul of the machine was carried out at the start of 2024. 👉 Machine is Air Compressor driver, installed at Bechtel Ammonia plant. 👉 Make: GE 👉 Year: 1964 👉 Rated Capacity: 8020 HP Major Findings: - Erosion in casing, diaphragms sealing area & rotor in LP stages - Increased interstage seal clearances - Slightly increased bush clearance in steam chest assembly Rectification & Replacement: ⭐ Replacement of rotor ⭐ Casing build up by welding, grinding & lapping done. Contact check of diaphragms ensured ⭐ Active side thrust pads replaced ⭐Steam Chest Bushing replaced. ⭐ Steam Chest linkages adjustment (Final result, RPM maintained within 2 rpm fluctuation) ⭐ All clearances maintained within recommended range ⭐ Centering carried out with dummy shaft ⭐ OST, Oil flushing carried out at end Major issue faced: 👉 Diaphragm side slip maintenance due to old bottom key design, rectified through time-takjng hit-and-trial by welding, grinding, & side slip check 👉 Butt gaps of seals, rectified by precisely filing seals, targeting minimum butt gaps.

🔍 Inspection Focus: Safe Entry Requirements for Machinery Spaces in UMS Mode **Inspection Point:** Are engineers familiar with safe entry requirements to the machinery space when operating in UMS mode, especially regarding the use of the dead man alarm where fitted? Key Aspects to Verify: Safe Entry Procedures: Ensure documented procedures exist to prevent solitary entry into the engine compartment during unattended periods without informing the bridge. Confirm regular contact intervals during entry are maintained. Alarms and Signaling: Verify the presence and functionality of a dead man alarm system (where installed). Check that the personnel alarm automatically alerts the navigating bridge or officers' quarters if not reset within 30 minutes (IMO International Codes on Alarms and Indicators, 1995. 7.1.1). Ensure the engineers’ alarm operates if the machinery alarm is not acknowledged within a period not exceeding 5 minutes (Resolution A.1021(26) 8.3). Signage and Procedures: Confirm safe entry requirements are clearly posted at the accessible entrance to the machinery space. Ensure procedures detail regular and frequent contact with the bridge or cargo control room unless a dead man alarm system is fitted. Fundamentals According to Conventions, Rules, and Recommendations: Informing the Bridge: Procedures must ensure personnel do not enter the machinery compartment alone during unattended periods without informing the bridge. Periodic Contacts: Maintain contact at predetermined intervals to ensure supervision and quick emergency response. Dead Man Alarms: Ensure alarms are capable of alerting the bridge if not reset within specified periods, enhancing safety for engineers in UMS mode. Posting Requirements: Clear posting of safe entry requirements ensures all engineers are aware of procedures and alarm usage. By verifying these aspects, we can ensure engineers are well-versed in safe entry procedures, thereby maintaining personnel safety and operational integrity in UMS mode. #MaritimeSafety #UMSMode #Inspection #Engineering #MaritimeIndustry #SafetyProcedures #IMO #OCIMF #DeadManAlarm

WPQ & WPQR (WELDER PERFORMANCE QUALIFICATION) Evaluates a welder's ability to produce sound welds according to specified welding procedures and standards. Key Aspects of WPQ: 1.Test the welder 2.Testing and Inspection 3.Qualification of welder 4.Documentation and Certification 5.Maintenance and Renewal Detail Explanation: 1.Test the welder: — The welder performs a test weld under controlled conditions, typically based on a Welding Procedure Specification (WPS). The test piece, known as a coupon, is prepared in the same way as the actual work would be performed. — The test should mimic actual job conditions, including the type of material, joint configuration, welding process, and position (e.g., flat, horizontal, vertical, overhead). 2.Testing and Inspection: Visual Inspection: The test weld is visually inspected for surface defects such as cracks, porosity, and incomplete fusion. Nondestructive Testing (NDT): Techniques such as radiographic testing (RT) or ultrasonic testing (UT) may be used to detect internal defects. Destructive Testing: Tests like bend tests, tensile tests, or macro etching may be performed to assess the weld's mechanical properties and integrity. 3.Qualification : The results of the WPQ determine the range of qualifications for the welder, including the types of welds they can perform (e.g., groove or fillet), the materials and thicknesses they can work with, and the positions they are qualified 4.Documentation and Certification Welder Qualification Record (WQR): The results of the WPQ are documented in a WQR, which provides a detailed account of the test, including the welder's performance and the range of qualifications. Certification: If the welder passes the WPQ, they are issued a certification or qualification card. This document certifies that the welder has met the required standards and specifies the scope of their qualification. 5.Maintenance and Renewal Welders must perform welding tasks within their qualification range to maintain certification. If they do not weld for a specified period, they may need to undergo retesting or requalification. #WPQ #WPQR #WELDING #ISO #API #ASME
