Now, pointing out the locations and directions of structure excessive motion is easier then before • We employ two methods of structure analysis utilising vibration as follow: • Operational Defection Shape (ODS) • Modal Analysis • Operating Deflection Shape (ODS) • Provides information on how the machine structure move during operational • How? • Vibration measurements are collected at several locations on a machine • Transfer functions are calculated between reference locations to other sensor locations. • Animate Structure Analysis ODS of tandem IG fan with high vibration due to combination problem
Now, pointing out the locations and directions of structure excessive motion is easier then before • Modal Analysis • Determines the fundamental vibration mode shapes and corresponding frequencies at which vibration naturally occurs analytically. • Approach: • Operational Modal Analysis (OMA) • Experimental Modal Analysis (EMA) • This helps us (and our client) to adjust their equipment accordingly in order to reduce system vibration that cause by resonance. Structure Analysis APPLICATIONS Operating machinery Mechanical structures with/without rotating components (e.g. turbines, engines and gas compressors) Large civil engineering structures (e.g. bridges and buildings subjected to ambient loads) Maritime structures (e.g ships and offshore structures) Compressor and motor base displacement magnitude
Find leaking valves long before detection by conventional methods or conservative instrumentation. • Detection of erosion damage in the body and trim of a bypass valve. • May avoid: • the potentially catastrophic loss of containment of hazardous fluid which lead to: • emergency shutdown, and • subsequent loss of production. • product losses to the flare and fugitive emissions • excessive valve damage due to prolonged leakage • Able to detect and estimate the size of valve leaks during operation. Valve Leak Detection APPLICATIONS Manual Operated Valve Actuated Valve Shut-Down Valve (SDV) Safety relief valve (PSV) Ball valve Plug valve Gate and globe valves Slimline Double Block & Bleed (SDBB) and Needle valves Butterfly valve, wafer and lug type Check valves, dual plate, piston, swing and non slam type
“Search for a peak to detect your leak” - Midasmeter • Find the leak (Detection) • Scrutiny of all available valve on site to identify through-valve leakage. • Equipment is Intrinsically Safe (IS) for use in hazardous/gaseous environments. • Measure the leak (Quantify) • Quantitative equipment is used to quantify the internal valve leak rate. Valve Leak Detection How to determine the valve condition using MidasMeter
Determine your piping design is subjected to or free from any dynamic vibration force based on your design specification is crucial. • Vibration in piping induce cracks and leaks due to fatigue failure of the pipe. May lead to major disaster if lack of mitigation action taken. • Under collaboration with VibraTec who is French leader of vibration and acoustics, we are able to predict set of piping vibration as below: • Flow Induced Vibration (FIV) – vibration caused by kinetic energy of turbulent fluid • Acoustic Induced Vibration (AIV) – vibration caused by restricted orifice such as relief valve, control valve or orifice plate. • Pulsation Induced Vibration (PIV) – vibration caused by mechanical equipment transmission. • Our set of calculations are from Energy Institute (EI) Guide lines: Guide Lines for the Avoidance of Vibration Induced Fatigue Failure in Process Pipe Work. Piping Dynamic Vibration
Determine your piping design is subjected to or free from any dynamic vibration force based on your design specification is crucial. • The main causes of these problems can be: • Harmonic piping system response due to: • Incorrectly installed supports, • Missing supports, • Structures too soft to support the pipes. • Pulsating flow due to high excitations produced by process machines and: • Incorrectly designed pulsation dampers, • Missing pulsation dampers or restricted orifices. Piping Dynamic Vibration ODS of a gas export line, including the supporting structure Improvement of piping support to reduce vibration
Evaluate the strength and stiffness of a product/design by calculate the component stress and deformations. • Employ finite element method (FEM) to calculate component displacements, strains, and stresses under internal and external loads. • Common design goal is excellent product performance and factor of safety (FoS). • Finite Element Analysis (FEA) services are: • Structural Analysis – constant (static) or dynamic load. • Linear and Non-Linear Stress Analysis • Vibration Analysis (Frequency) Finite Element Analysis (FEA) Structure stress due to machine horizontal motion Factor of safety of pressure vessel design
CFD is a powerful engineering tool for predicting real complex-physics process behaviour. • CFD provides a detailed understanding of flow distribution, pressure losses, heat transfer, particulate separation, collection efficiency, etc. • Typically applied to: • Design evaluation, verification and optimization • Performance evaluation • Problem solving, what-if scenarios • Study off-design operating conditions • CFD simulation is a guidance and reduce testing cycle but does not a replacement.
