New and upcoming integrity management software and training from TWI

CrackWISE

TWI has developed and marketed structural integrity software compliant with British Standard BS 7910, the UK flaw assessment procedure, since the early 1990s, when DOS-based program CrackWISE was first released. Since then, the software has been redesigned and re-released on several occasions, reflecting changes in both the underlying procedure and the software/hardware platforms available to engineers.

A new version of BS 7910 was released in December 2013, superseding the previous edition (published in 2005 and amended in 2007). This represents a major revision, particularly in the clauses relating to fracture. The new content includes methods for assessing the effects of strength overmatching and undermatching in welds, for assessing crack-tip constraint and for incorporating the effects of residual stress. These changes have prompted the development of a new version of CrackWISE, Version 5 (CW5), replacing earlier versions of the software.

Even a straightforward analysis to BS 7910 typically requires the use of multiple parametric equations, to calculate (as a minimum) stress intensity factor (SIF) and reference stress (ref).Whilst simple analyses of known flaws can in principle be carried out using standard software tools such as spreadsheets, there is often a need to carry out complex and iterative calculations. This is particularly pertinent to propagating flaws (for example, assessment of fatigue crack growth or ductile tearing) and to the calculation of limiting conditions (for example, the maximum tolerable flaw size in a structure under given conditions). Specialist software is invaluable in performing, reporting, editing and archiving such complex calculations, and it is for such situations that CrackWISE(CW) was developed. 

Practical application of BS 7910 procedures for the assessment of flaws in structures
This is a four-day course for structural, civil, design, maintenance, welding and inspection engineers and for those responsible for optimising asset performance or risk management. It also includes use of CrackWISE software.

 IntegriWISETM

IntegriWISETM is the new Fitness-For-Service (FFS) assessment software developed by TWI to assist engineers in evaluating the integrity of ageing pipework, pipelines, storage tanks, boilers, pressure vessels and high storage tanks. IntegriWISETM is the codification of API 579 generic assessment procedures (level 1 and level 2), together with the material database of ASME VIII, ASME B31.3, ASME B31.4, ASME B31.8, API 620, API 650, and PD5500.

IntegriWISET is designed to assess pressure equipment against different damage mechanisms such as general and local metal loss, pitting corrosion, blisters, hydrogen damage, crack-like flaws and laminations. In addition, the system provides evaluation techniques for assessing resistance to brittle fracture.

IntegriWISET offers the next generation in plant integrity management systems, by allowing engineers and managers to improve safety and plant availability and reducing outage and maintenance costs.

FFS Assessment, based on API 579-1/ASME FFS-1 2007

A three-day course covering Level 1 (for plant inspectors) and Level 2 (for engineers) FFS assessments, in accordance with the latest edition of API 579, issued as a joint API/ASME document, API 579-1/ASME FFS-1 2007.

RiskWISETM

TWI has been active for over 15 years in the development of Risk-based Inspection (RBI) and Risk-based Management (RBM) approaches. RBI is an integrity management practice employed to identify plant and equipment at risk of failure.

TWI will soon launch RiskWISET 5, the most up to date suite of RBI software for process plant, and a new RiskWISE to accommodate applications for subsea pipelines is currently under development. RiskWISET 5 is a suite of versatile and easy-to-use RBI engineering software that enables plant personnel to confidently manage the risk and associated issues for the continued safe and economic operation of their plant and equipment. The risk-based approach in RiskWISET 5 is in accordance with industry-accepted and proven concepts of RBI, meeting the audit team concepts detailed in API Recommended Practice (RP) 580 - Risk Based Inspection (RBI) and API RP 581 - Risk Based Inspection Technology.

Since its start of development in late 1990s, RiskWISET remains one of the few commercially available RBI suites for plant-wide application to all types of process and power generation plants with more than 100 licences in the oil and gas and power industry across the world.
