IMS PEI
6.4/10Cloud-based pressure equipment integrity software from Cenosco that plans inspections using risk-based inspection (RBI) and corrosion calculations, for oil, gas, chemicals and process plants.
Data last updated November 2026 · Our methodology
Overview
IMS PEI (Pressure Equipment Integrity) is a module of Cenosco's IMS Suite. Cenosco and Shell built the suite together over about 20 years, and Cenosco took full ownership of its IP in a deal announced in December 2023 and closed in January 2024. The module runs a degradation management workflow that decides which pressure and civil equipment to inspect and when, records results in an equipment condition history, and keeps an audit trail. It covers an equipment register and asset hierarchy, corrosion loops, CML and thickness data, inspection schedules that generate the next due date automatically, and RBI. RBI can use Shell's semi-quantitative S-RBI method or API 581, in qualitative through fully quantitative forms. The module also offers corrosion rate prediction, a corrosion management framework fed by data historians, lifecycle cost calculations, dashboards and 2D/3D visualization. Field inspectors use IMS4Field, an offline checklist app that syncs with IMS. The software suits refineries, LNG plants, chemical sites and upstream operators that run formal inspection programs. Named users include Tüpraş, NAM, Thaioil and Egyptian LNG. It interfaces with SAP, JD Edwards and Maximo for maintenance execution. It is sold as SaaS on Microsoft Azure, with shared, dedicated or on-premise hosting. Pricing is quote-based, and Cenosco sells implementation, data migration and integration services alongside it. The main limitation is that it is a specialist integrity tool, not a full CMMS. Maintenance work is usually executed in a connected ERP. There is also almost no independent user review data, so buyers have to rely on vendor case studies and references.
Our Rating
Who IMS PEI is best for
Best software for Energy CompaniesGood fit
It was built with Shell and is deployed at refineries, LNG plants and upstream operators such as NAM, Tüpraş and Thaioil.
It suits large asset owners, with ERP integration to SAP and Maximo, SSO and ISO 27001-certified hosting.
Inspection and integrity engineers use it to schedule inspections and record equipment condition, though maintenance work itself runs in a connected CMMS.
Cenosco also targets chemicals and pulp and paper plants that run pressure equipment.
Less suited
Quote-based enterprise pricing and the need for implementation services make it a poor fit for small firms.
Pros & Cons
Pros
- Supports both Shell's S-RBI method and API 581, from qualitative to fully quantitative, so one tool can handle risk ranking across a whole plant.
- Rests on more than 20 years of joint development with Shell, and Cenosco reports use on more than 200 assets in over 40 countries.
- Interfaces with SAP, JD Edwards and Maximo, so inspection findings can feed maintenance execution in the ERP.
- The IMS4Field app works offline by default, and NAM reports going paperless while staying auditable.
- Hosted on Microsoft Azure, with ISO 27001:2022 certification and 2FA or SSO/ADFS authentication.
Cons
- No public pricing. Buyers need a sales process and typically pay for implementation and data migration services.
- Independent reviews are almost nonexistent: Capterra shows a single rating, and other listings have none.
- It focuses on inspection and integrity, not a full CMMS, so work order execution and spare parts usually stay in a separate ERP.
- Cenosco itself advises against on-premise hosting, which may not suit operators with strict data residency rules.
- The older IMS Offline app was deprecated in 2024, so sites still on it had to move to IMS4Field.

Frequently Asked Questions
Cenosco publishes no prices and quotes each deployment individually. One third-party directory listing shows a starting price around 29,500 per year, but Cenosco has not confirmed that figure, so get a formal quote.
It includes Shell's semi-quantitative S-RBI method and API 581. Assessments can be qualitative, semi-quantitative or fully quantitative, with configurable generic failure frequencies and inspection effectiveness criteria.
Yes. Cenosco says IMS PEI interfaces with SAP, JD Edwards and Maximo, and it can connect to data historians for corrosion monitoring. Cenosco also sells integration and data migration services.
Yes, through the IMS4Field mobile app, which is designed for offline use by default. A connection is needed to prepare the work and to sync results back to IMS.
IMS Suite is SaaS on Microsoft Azure data centers, with shared or dedicated single-tenant options. Authentication uses 2FA or SSO/ADFS. Cenosco holds ISO 27001:2022 certification and has reported ISO 22301 certification for business continuity.
