Consulting on Certification

Regulations are increasingly influencing more aspects of our daily life and are also imposing additional obligations and requirements that can impact, directly or indirectly, on the viability or success of your product(s) or assets.

Extensive experience, insights and knowledge are required to ascertain and apply the correct form of any requisite Declaration of Conformity, or the prescribed Certification, or the applicable standards of Drawings and Workshop Approvals, or the authorized testing regime and/or scope, etc.

IMPAC will support you in your project to ensure that you will meet the requirements appropriate to your workshop, facilities, processes and product, whether these are in Marine off-shore, land-based or on-shore applications.

We can advise you on the right choice of Rules, Regulations and Directives, as well as providing guidance on production-specific standards.
As a consequence we can:

  • Reduce your costs for certification
  • Advise you in advance regarding the optimal certification scope
  • Increase your scope of application, where possible
  • Improve your time management by identifying the right choice of regulations with which to comply

Verification involves the activities required to confirm that the safety barriers of an installation or an asset are designed, constructed and maintained in a condition that is fit for purpose and can perform their function safely.

This is typically done through identification of all barriers or safety critical elements (SCE) of an installation and establishing performance standards or criteria for these SCE’s, with regards to functionality, availability and vulnerability. Once the standards are agreed upon, the independent verifier (or independent verification body – IVB) then describes how these are to be verified in a written verification scheme that describes how the verification is to be conducted.

 

What we do

Our Verification include:

  • Identification and description of SCEs and performance standards
  • Development of written schemes of examination/verification
  • Verification of design according to selected standards and requirements
  • Verification of construction activities according to agreed requirements
  • Vendor inspections and verification of FAT/SAT
  • Verification of commissioning activities
  • Verification of installations in service according to the written verification schemes
  • Verification of modifications
  • Provide verification statements and communicate with applicable authorities on compliance issues

What you get

  • Transparent and recognized best practice approach for managing safety barriers on your installation
  • Independent statement of design, construction, commissioning and/or condition of safety barriers that can be shown to stakeholders such as authorities, insurance companies, owners/partners, employees, and corporate management
  • Efficiently help reducing (major accident) risk in your organizations
  • Verify or write which performance standards and/or barriers are missing at your operating assets and give recommendations for further improvements
  • Carry out vendor inspections to ensure quality of purchased equipment
  • Expediting activities to ensure timely delivery according to contractual agreements

 

How can we help you?

Using a verification scheme based on performance requirements for safety critical elements, IMPAC can verify that the design, construction and maintenance of the SCE meets the set criteria.

Based on the verification, IMPAC will issue a statement that describes the status – which can then be shown to applicable authorities to demonstrate compliance with regulations, international standards or recognized best practice.

Plant inspections are an integral part of risk management process. They are necessary to ensure equipment is safe and reliable to minimize risk to people, the environment and plant production downtime.

Plant Inspections can be categorized as;

  1. External Inspections Periodically,
  2. Internal Inspections During Planned Shutdown and
  3. Emergency Inspections During Breakdown.

Risk Based Inspection

Risk Based Inspection is a risk assessment and management process that is focused on the loss of containment, of pressurized equipment in processing facilities, due to material deterioration.

These risks are managed primarily through equipment inspection. The technique is used to determine inspection intervals, method of inspections and scope of inspections. For example, you may determine your pressure vessel internal inspection based on API 510 requirement or carry out the risk based inspection and determine the interval, method of inspection and scope of inspection. The API 510 allows you to choose this alternative method. API RP 580 provides the definition and general requirement for risk based inspection and API RP 581 introduces you to a specific quantitative methodology for risk based inspection implementation.

The key equipment on a plant that are inspected and their respective codes and standards applicable for in-service inspection, repair and re-rating are described below.

Pressure Vessels

The following codes and standards and recommended practices are used for pressure vessel inspection:

  • API Standard 510; Pressure Vessel Inspection Code: In-Service Inspection, Rating, Repair, and   Alteration
  • API RP 572; Inspection Practices for Pressure Vessels
  • API RP 576; Inspection of Pressure-relieving Devices
  • API RP 571; Damage Mechanism Affecting Fixed Equipment in the Refining Industry
  • ASME PCC-2; Repair of Pressure Equipment and Piping
  • National Board Inspection Code NB-23
  • ASME PCC-2, NB-23 and API 510 can be used for pressure vessel repair

Piping Systems

The following codes and standards and recommended practices are used for piping inspection:

  • API Standard 570; Piping Inspection Code: In-service Inspection, Rating, Repair, and Alteration of Piping Systems
  • API RP 574; Inspection Practices for Piping System Components
  • API RP 571; Damage Mechanism Affecting Fixed Equipment in the Refining Industry
  • ASME PCC-2; Repair of Pressure Equipment and Piping
  • ASME B16.5, Pipe Flanges and Flanged Fittings
  • ASME PCC-2, NB-23 and API 570 can be used for Piping repair.

 Storage Tank

Following codes and standards and recommended practices are used for storage tank inspection:

  • API Standard 653; Tank Inspection, Repair, Alteration, and Reconstruction
  • API RP 575; Inspection of Atmospheric and Low-Pressure Storage Tanks
  • API RP 651; Cathodic Protection of Above ground Petroleum Storage Tanks
  • API RP 652; Lining of Above ground Petroleum Storage Tank Bottoms
  • API RP 571; Damage Mechanism Affecting Fixed Equipment in the Refining Industry

Steam Boiler

The following codes and standards and recommended practices are used for steam boiler inspection:

  • ASME Section VII Recommended Guideline for the Care of Power Boilers
  • API RP 573; Inspection of Fired Boilers and Heaters
  • API RP 571; Damage Mechanism Affecting Fixed Equipment in the Refining Industry

Process Heater

The following codes and standards and recommended practices are used for process heater inspection:

  • API RP 573; Inspection of Fired Boilers and Heaters
  • API RP 571; Damage Mechanism Affecting Fixed Equipment in the Refining Industry

Valves

The in-service inspection code for Pressure-relieving Devices is API RP 576. This code is used in conjunction with API STD 510. The API 510 determines the requirement for inspection interval and API RP 576 specifies the inspection practice. The in-service code for other industrial valves such as Globe Valve, Gate Vale, Check Valve and Plug Valve follows API STD 570 and API RP 574. If a major repair is carried out, then valve testing might be needed, which can be done based on API 598.
