Electrical Systems Safe Operability Review (SAFOP)

SAFOP process is a systematic approach to review the safety and operability of the design of an electrical installation from a technical, maintenance and operational viewpoint. A SAFOP involves the implementation of three studies by a multi-disciplined team of engineers, operations and safety personnel. The three studies include:

SAFAN analyze the physical layout and accessibility of electrical equipment and related facility and assesses the potential for hazards to personnel who has to operate, work on, or be in the vicinity of the facilities.

TSYSOP (System Security and Operability) studies the functioning and operation of the electrical network equipment, its components and auxiliaries and considers these in terms of fulfilling the intended security of supply and operating requirements whilst preventing or minimizing hazards and production losses. It assesses the adequacy of the protection and control schemes provided; the potential for, and consequences of, failure, malfunction or mal-operation of the equipment and identification of deficiencies in the design of the electrical installation that affect both the operability and maintainability of the system.

OPTAN (Operator Task Analysis) examines the tasks of the operators (electrical and others) of the electrical system in control and maintenance situations, in both normal and abnormal conditions. It assesses whether adequate facilities are provided and addresses the adequacy of operator interface and operator’s ability to carry out the required tasks and to do so in a safe manner without error.

Today, Sky Engineering has own leased land (approximately 26000 sq. ft) from RIADA and complete infrastructure facility for execution.

In the coming future, the plan is to have muti-city offices and to be a single point solution for electrical system.

The Benefits

A SAFOP review is recorded in a SAFOP report which contains detailed significant findings and conclusions in the form of worksheets and includes the main recommendations to avoid or minimize problems identified by the SAFOP team. Results of a SAFOP include:

  1. a fitness for purpose assessment of the facilities;
  2. a better understanding of how the integrated power system will work and its operational limitations;
  3. a list of proposed tasks to improve the safety and operability of the asset;
  4. verification of the robustness of the system with suggestions for reducing system susceptibility to upsets;
  5. a system suited to local circumstances and compatible with local working practices and procedures;
  6. avoiding nuisance trips and thus downtime of existing plant during tie-in and commissioning;
  7. improving safe working practices highlighting safety hazards during installation, commissioning and operation;
  8. Testing of Electrical Equipment for conducting Pre-Commissioning and Residual Life Assessment (RLA)
  9. identify the required information to carry out operational tasks in a safe manner under normal and emergency conditions.

Participating Team for SAFOP

The participants usually required at the review include the team chairman/facilitator, secretary, project engineer, electrical design engineer, process plant operator; electrical maintenance engineer, safety engineer, design consultants and contractor / manufacturer if applicable. The choice of team chairman/facilitator is crucial. The team chairman/ facilitator must be an experienced engineer with a sound theoretical and practical knowledge of the design and operation of electrical systems in oil and gas production or processing facilities. To ensure the effectiveness of the SAFOP, the team chairman/ facilitator must be trained and practiced in applying SAFOP techniques. Further to ensure impartiality, the team chairman /facilitator should be an independent party, not involved with the project.

WHAT IS EMC STUDY

In the present electronic world, Electromagnetic Interference plays an important role in system design. The interference may interrupt to distort the expected services. Electro Magnetic Studies (EMC) is applicable for Power Plants, Oil & Gas Installations, Offshore Platform Facilities, Steel Plant, Aluminum Plant.

Hazard identification/HAZID

Hazard identification is the first and, in many ways, the most important step in a risk assessment. If a hazard is not identified, it is unlikely to be managed effectively. Different industries, applications and lifecycle timings demand different solutions and many different tools for identifying hazards have been developed. Some have wide applicability, others are very narrow in scope or have been developed for one-off applications, equally the level of detail and documentation ranges from the very extensive to the bare minimum.

Sky Engineering provides the services of conducting HAZID study through experienced and industry recognized professionals.

HAZOP study/PHA

Hazard and Operability (HAZOP) study is a structured and systematic examination of a product, process, procedure or system in order to identify hazards and operability issues. The method systematically examines how each part of the ‘design’ will respond to deviations in key parameters by using suitable guide words. Originally developed to analyze chemical process systems, HAZOP is very commonly used today throughout the process industries and is synonymous with PHA in North America (Process Hazard Analysis). It has also been extended to other types of systems and complex operations, including mechanical and electronic systems, procedures and software systems, and even to organizational changes and to legal contract design and review.

Sky Engineering provides the services for:

Facilitating HAZOP workshops

Recording HAZOP workshops using leading HAZOP software including PHA Pro, PHA Works, HAZOP Manager, HAZOP Leader Provision of independent process engineers Layer of protection analysis (LOPA)

Sky Engineering experience ranges from small, single node HAZOP studies through to complex, comprehensive HAZOPs for entire facilities. We have a large number of experienced and client approved HAZOP and LOPA chairs/facilitators and highly proficient scribes/technical secretaries.
