Specialised Studies


Stress Analysis

Stress analysis is used to evaluate the effects of pressure, static and dynamic loads on the piping. We model the piping systems & its connected equipment, other process equipment of the system and experiment by applying various static and dynamic loads through our model. We assess the results and validate the model to comply to the Industry standards.

Finite Element Analysis

Finite Element Analysis is a detailed method for analyzing and evaluating complicated structural problems. Finite Element Analysis includes various design analyses, design optimization, comparing the designs with established standards and analyzing the failure of process components.

Structural Analysis

Structural Analysis studies the effect of external forces on tangible objects like constructed structural elements and estimates the behavior of various structures when different loads act on them. A thorough Structural Analysis aids in the design and determination of element sizes and in selecting the right material for structural elements.

Computation Fluid Dynamics

Understanding meshing requirement and quality are highly important in Computation Fluid Dynamics. Our CFD team possesses hands-on experience, skill and complete understanding of dynamics and fluid physics. We use various fluid simulation strategies, techniques and advanced software to perform an array of engineering activities such as calculating performance, validating design, evaluation of operating conditions etc., and provide optimum solutions with lesser downtime.

Vibration Analysis

Vibration analysis identifies and measures misalignment, bearing defects, imbalance, mechanical looseness, bent shafts, gear drive faults, and resonance present in an equipment. Information from this analysis could be used for evaluating the root cause of vibration anomalies and correction can be provided.

Surge Analysis

Evaluating the extent of surge for hydraulic systems is of paramount importance to avoid leakage and failure of the whole system. Sudden changes in Surge pressure lead to damage to pipeline, damage to equipment, bursting of pipeline etc., A thorough Surge Analysis estimates the system, determines the reason for surge and will help in selecting the suitable mitigation recommendation. Our team of experienced hydraulic engineers equipped with advanced software can ensure that the client’s requirements are fulfilled to the highest standards

Flare Radiation & Dispersion Study

In production process, flaring is the controlled burning of natural gas. It is very important to determine the thermal radiation and estimate stack height during flaring. Our comprehensive study will outline the extent of flare radiation and dispersion to safely dispose of the gas during power outages, failure of equipment, and other emergencies or ‘upsets’ during processing or drilling operations through flaring or ventilation.

Power System Studies

Power System Studies must be performed before specifying or purchasing an equipment. Power System Studies include analysis of over-current coordination, load flow, short circuit, arc flash hazard and motor starting studies. The result of the analysis is then used for specifying equipment ratings. Power System Studies must be performed with keeping in mind the following,


  • Design a safe system
  • Standardize equipment sizing and protection methods
  • Limit bus voltage drops to 5–8% under maximum load conditions and to 15–20% during large motor starting
  • Set overcurrent devices to protect equipment from damage
  • Selectively shut down sections of the power system in response to a system disturbance
  • Limit arc fault energy levels to 40 cal/cm² or below

When analysing an existing electrical distribution system, the need to perform a load flow or motor-starting study is diminished. At this point, unless there is an obvious loading or motor-starting problem such as transformers running hot, low voltage under normal or motor-starting conditions, or motors failing prematurely, the effort should be focused in the areas of short circuit, overcurrent coordination, and arc flash. These studies are all life safety related, and if problems are found, they must be rectified immediately.

Our engineers can perform the following Electrical Power System Studies

  • Harmonic Analysis
  • Short circuit Study

Load Flow Studies

It is the analysis of the normal steady state operation of a power system. Load Flow Studies involve calculation of voltage drop on each feeder, voltage at each bus, power flow and losses in all branch and feeder circuits. The study determines if the system voltages remain within specified limits under normal or emergency conditions and also evaluates whether equipment like generator, transformers and conductors are overloaded.

Relay Coordination

In general, there are two or more series protective devices between the fault point and the power supply and these devices must be coordinated to make sure that the device nearest the fault point operates first. Other upstream devices must be designed in order to operate in sequence for providing back-up protection, in case if any of the devices fails. This is called ‘Selective Coordination’. To meet this requirement, the devices must be rated or set to operate on minimum overcurrent, in lesser time, and must be selective with the other devices too. Maximum protection to equipment, production process & personnel can be accomplished if these criteria are met. Protection and coordination are often in direct opposition with each other. Protection may have to be sacrificed for coordination, and vice versa. iFluids, over the years, have gained experience in designing optimum coordination and protection.

Arc Flash Study

When a flashover of electric current leaves its original path and travels in the air from one conductor to another or to ground, Arc Flash happens, which may often turn violent and may also cause injury or death when a human is in close proximity.

The causes of Arc Flash may vary from corrosion, dust, accidental touching, faulty installation, condensation, dropping of tools, material failure, etc., Worker’s proximity to the hazard, Temperature, Time of circuit break are the top important factors that determine the severity of an arc flash injury. An Arc Flash may cause fire (could spread rapidly through buildings), simple burns (Non-FR clothing can burn onto skin), blast pressure (upwards of 2,000 lbs./sq.ft), heat (upward of 35,000 degrees F), sound blast (noise can reach 140 dB – loud as a gun) and dangerous flying objects (often molten metal).

We have developed specific approach boundaries for protecting personnel while also working on or near energized equipment. These boundaries are Flash Protection Boundary (outer boundary), Limited Approach, Restricted Approach and Prohibited Approach (inner boundary).

We offer first-class technical consulting to prevent hazards and recommend various proven protective methods including de-energizing the circuit, work practices, complete insulation, guarding, barricades, ground fault circuit interrupters (GFCI) and grounding (secondary protection).
