Pressure System Inspections

In service inspections.

Planning and execution of inspections, repairs and modifications of minor, major and intermediate pressure systems and storage vessels. Application and implementation of current statutory and regulatory directives, codes of practices, recognised national and international codes and standards as detailed;
PSSR 2000, API 510, API 570, API RP 571, API RP 572, API RP 573, API RP 574, API RP 576, API RP 577, API RP 579-1, API RP 580, L122, L111, SAFed PSG 1, SAFed PSG 5, SAFed PSG 6, PED

IRISNDT is a Type A UKAS accredited company to ACT as a competent person to provide inspections, write and authorise WSE’s, inspect repairs and modifications and to perform advanced and conventional NDT techniques for Major, Intermediate and minor pressure systems. This accreditation provides our COMAH and Non COMAH regulated clients the reassurances they demand.

PSSR 2000 compliance

The Pressure Systems Safety Regulations 2000 (PSSR) cover the safe design and use of pressurised systems to prevent resinous injury from the hazard of stored energy (pressure) due to the failure of a pressure system or one of its component parts. Therefore they must be inspected thoroughly by a ‘Competent Person’ to ensure that they can operate within the safe operating limits until the next inspection is due. The system must not be operated beyond the next inspection due date unless a postponement is made in accordance with PSSR regulation 9

Storage Tank Inspections

Out of Service and In service inspection following the guidelines in EEMUA 159 and API 653. When a tanks geometry or locations falls outside these guidelines IRISNDT’s competent persons can generate tank specific WSE’s to comply.

Visual Assessments, NDT surveys, Settlement Assessments, Laser surveys, Bund surveys, repair recommendations including CAD drawings
IRISNDT can utilise all technologies to insure the most effective and detailed test results with advanced NDT and conventional NDT, inspection technologies such as but not limited to are MFL, SLOFEC, PEC, ACFM, Eddy Current Array and PAUT Corrosion Mapping.

IRISNDT have several different methods available for remote access and inspecting through insulation to help savings on scaffold access and insulation removal and reinstation.

Risk Based Inspection (RBI)

Risked Based Inspection (RBI) typically requires significant upfront investment by the owner/user. However, with the use of IRISNDT software management (MT Field Services), skills, experience such as understanding failure mechanisms and the ability to record quality, reliable and repeatable data an RBI approach to plant inspection can be adopted and managed by IRISNDT. Benefits of RBI from more traditional time based inspections can lead to reduced downtime, extended inspection intervals as well as improved safety standards which can result in genuine cost savings.

The following documents cover RBI and it’s advantages in more detail, API 580, API 581 and EEMUA 206.

Pressure Vessel Inspection

IRISNDT have Plant Inspectors and Inspection Engineers qualified to API 510 and ASME Levels 1,2 & 3. We can perform In service and Out of service inspections following API/ASME guidelines, Client specific procedures or bespoke WSE’s generated by IRISNDT.

IRISNDT can provide Advanced NDT solutions and inspection plans that can be utilised whilst plant is on stream. PAUT corrosion mapping for example can be deployed to monitor the wall thickness at regular intervals recording encoded accurate data.

To reduce the risk of entry small confined spaces often associated with pressure vessels, IRISNDT can deploy remote and robotic solutions for out of service inspections. These devices can follow pre-determined inspection plans to ensure all areas of interest are captured and to ensure encoded repeatable inspections. With the added reassurance of software like 3D locator, in depth reports can be provided with high quality HD images.

UKAS RG 2 Category 1, 2, 3, 4 & 5 Inspectors

IRISNDT can provide Chartered Engineers, Incorporated Engineers, Senior Inspection Engineers, Inspection Engineers, Plant Inspectors, Technicians and Apprentices. We value the experience and training required for our employees to gain these qualifications and we continue to regularly invest in their training and development.

Following the guidance of our UKAS 17020 our employees are witnesses and assessed in accordance with the points system and criteria set out by the accreditation societies, referencing the example below from Appendix 1 of UKAS RG 2;

Qualification Categories

Category 1. Chartered Engineer as defined by the Engineering Council or equivalent (e.g. appropriate degree with relevant experience, NVQ Level V Engineering) including at least 3 years’ experience within an engineering discipline associated with in-service inspection of pressure systems.

Category 2. Incorporated Engineer as defined by Engineering Council or equivalent (e.g. appropriate HNC with relevant experience, NVQ Level IV Engineering) including at least 5 years’ experience within a relevant engineering discipline of which at least one year** shall have been spent working within an engineering discipline associated with in-service inspection of pressure systems.

Category 3. Engineering Technician as defined by Engineering Council or equivalent (e.g. appropriate ONC with relevant experience, NVQ Level III) having a minimum of 5 years’ experience within a relevant discipline of which at least one year shall have been spent working within an engineering discipline associated with the in-service inspection of pressure systems or,

Category 4. Person trained* in a relevant engineering discipline with a recognised and documented engineering apprenticeship with a minimum of 5 years’ experience within a relevant discipline of which at least one year shall have been spent working within an engineering discipline associated with the in-service inspection of pressure systems.

Category 5. Person with less than tradesman’s apprenticeship but with a minimum of 5 years*** spent working with or within the industry associated with pressure systems and has general knowledge of pressure systems and its operating environment. Personnel shall be placed on recognised training courses with appropriate documented tests in in-service inspection of pressure systems. The minimum age for this Category is 21 years.

* Persons in Categories 4 and 5 shall pass a qualifying test, established by the Inspection Body, associated with the particular inspection activities relating to pressure systems/equipment and this should cover relevant knowledge of the law, codes of practice and inspection techniques. ** Where a person meets the minimum requirement for a specific discipline and is to be trained in a second discipline, it may not be necessary to have experience of at least one year in the second discipline provided that the required competence can be demonstrated. ***For some routine, well-monitored activities this period may not be necessary.

Written Schemes of Examination (WSE’s)

Since the introduction of the PSSR Regulations in 2000, it has been a legal requirement for Owners/Users to have a WSE in place for all relevant fluids and systems, examples of these are;

  • Steam at any pressure
  • Any fluid or mixture of fluids which is at a pressure above 0.5 bar above atmospheric
  • A gas dissolved under pressure in a solvent (acetylene)

Once a WSE has been determined, it shall then be adhered to and carried out by a competent person, these duties include;

  • Review WSE and confirm it is suitable
  • Produce a written report for each examination
  • Notify Owner/User of repairs required
  • Identify action in case of imminent danger
  • Agree postponements of examination, where appropriate
  • Draw up or certify written schemes of examination

IRISNDT have the knowledge and expertise to cover both new and existing WSE requirements, keeping documentation and plant integrity in line with the most recent laws and guidelines.

Fitness for Service (FFS)

A fitness for service or fitness for purpose assessment is often carried out after multiple in-line inspections (ILI) which IRISNDT are compliant with having knowledge, expertise and technology to undertake these inspections in-house, negating the need for further party involvement(s).

Once the necessary inspections have been carried out and documented, we can offer a FFS assessment to all aspects of plant, we’re able to do this by reviewing existing data and plant cycle records, whilst factoring in damage mechanisms such as corrosion, fracture, creep and fatigue

IRISNDT Engineers have experience working in line with API 579 and have great knowledge of most recognised industry standard design codes.
