The Risk Based Inspection module of our NO-LEAK solution is able to perform the Semi-Quantitative Risk Assessment on piping and pressure vessels carrying water, oil, and gas fluids. It is anticipated that failure of any of these critical equipment could have dire consequences on the Asset’s HSE goals. Thus, in line with API 581 (amongst other international standards), this module ensures that the ‘Probability of Failure’ and ‘Consequence of Failure’ is accurately calculated whilst ensuring the correct Inspection frequency is specified.
The Fitness for Service Assessment module encompasses the assessments for the following equipment in line with various applicable codes and standards –
The Fitness for Service Assessment section encompasses the assessments for the following equipment –
This module was specifically designed to manage Cathodic Protection designs and remote monitoring of Cathodic Protection systems by both impressed and sacrificial systems.
Existing remote Cathodic Protection monitoring units can be connected to this module.
This module of the NO-LEAK solution was specifically designed for the management of Internal Corrosion.
We designed it because we noticed that in most Assets, Operators were not connecting the increased internal degradation rate to the increased inspection frequency – We thus hope that module helps operators quickly detect when their site activities are resulting in increased degradation rate beyond the prediction of the Risk Based Inspection module.
It is further divided into 2 sections:
This section of the Application is specifically directed at internal corrosion management. It is further divided into 2 sections:
This module is aimed at planning and keeping track of all well integrity activities alongside using the Swiss Cheese assessment technique to note failure points requiring immediate actions.
It is quite necessary to ensure the optimal operation of the wells as they are one of the most critical component of an Oil and Gas Asset.
It thus helps detail the current status of the Wells within an Asset.
This module is generally a reporting tool aimed at assisting Operators which do not have and Plant Maintenance CMMS solution aimed at recording or raising anomalies requiring actions or temporary deviations implemented on site.
It is divided into 2 namely:
This section is divided into 2 namely:
This module is aimed at ensuring all non-pressurized equipment are effectively assessed for its attendant criticality to the entire system. At the end of the assessment, Operators will be able to identify all non-pressurized Equipment which are important for the Asset to be functional enough to achieve the planned operational design.
This module is aimed at ensuring Operators are able to manage the movement and Integrity of all Safety Devices.
It thus tracks and reports on all Safety devices thus ensuring all Safety devices (PSVs, TSVs, PVSVs, Bursting Disks, etc.)’s replacement, testing, and repairs are managed optimally in line with the required regulatory requirements.
This section is aimed at ensuring all PSVs, TSVs, PVSVs, etc. replacement, testing, and repairs are managed optimally in line with the required regulatory requirements.
This module manages all pressurized equipment in a system manner and eases the management of these systems.
It helps instill the system-based review of equipment condition within a system volume.
With this section, a system status managed as each Equipment within a System contributes to the functionality of the system.
In the same manner, an Equipment’s failure within the group, affects the functionality of the System.
This module helps Senior Management keep track of the condition of high-risk equipment which could damage the organization’s production, and reputation if it fails during operation.
For an equipment to enter into this categorization, its loss of containment must have a high consequence on the Asset’s production or the Operator’s reputation.
From experience, about 8-15% of all Equipment in an Asset, are typically categorized as SECE.
This section ensures Senior Management constantly has an overview of the condition of high-risk equipment which could damage the organization’s reputation if it fails on site.
This module was strategically created for Operators with no CMMS.
It is aimed at planning all Inspection and Maintenance activities to be carried out on any Equipment in an Asset, in line with prescriptive requirements.

GeekyExperts are the best! The calculators are free to use and really simple, also you can get a lot of books in their shop! –
This application shall be able to perform the Risk Assessment of piping and pressure vessels carrying water, oil, and gas fluids. It is anticipated that failure of these equipment could have dire consequences on both living and non-living things alike hence, in line with international standards, the Application ensures that the ‘Probability of Failure’ and ‘Consequence of Failure’ is accurately predicted whilst performing the Risk Assessment for each equipment.
The modelled ‘Corrosion Mechanisms’ are as listed below:
The modelled Probability of Failure considers the following:
The modelled Consequence of Failure considers the following:
The modelled Risk Assessment is a 5 X 5 risk assessment with description as follows –
The modelled Inspection Planning typically considers the following in predicting the inspection plan:
In determining –
➢ Major Inspection
o Intrusive – Pressure Vessel
o Non-Intrusive – Piping and Pressure Vessel
➢ Intermediate Inspection
o Non-Intrusive – Piping and Pressure Vessel
The reference standards implemented for the various sub-sections of the Risk Based Inspection section are as itemized below:
The Fitness for Service Assessment section encompasses the assessments for the following
equipment –
The Pipelines are assessed in line with 2 methods – ASME B31G, Modified and RSTRENG methodology.
The Piping and Pressure Vessel section is in line with the API 579 Assessment Methodology. With its assessment, oil and gas operators can determine the maximum pressure a piping or a pressure vessel should be operated after a corrosion related damage has been assessed. The reference standards implemented for the Fitness for Service section are as itemized below:
This section is specifically created to cater for the Cathodic Protection design by both impressed and sacrificial systems, but the impressed current system has not been implemented. We are thus providing cathodic protection designs for only the sacrificial systems.
The sacrificial system is designed to cater for the following:
With this, Clients can determine:
In line with best practice, 4 sacrificial anode installation methods were designed
The reference standards implemented in this section are as detailed below:
This section of the Application is specifically directed at internal corrosion management. It is further divided into 2 sections:
The internal Corrosion Monitoring Equipment Assessment sub-section is aimed at confirming the corrosivity of the fluid on the corrosion loop that the monitoring equipmentis installed. Its assessment calculates the General corrosion rate based on the weight loss and the pitting rate in line with the NACE International standard after which the values are graded in severity.
The Chemical Treatment Assessment sub-section is aimed at confirming how efficient the Asset’s chemical treatments is performing. The following are typically a minimum of what this section shall be able to assess:
The above 2 sub-assessments were based on the following standards:
This section of the Application is aimed at planning all well integrity activities necessary to ensure the optimal operation of the wells. It also details the status (Integrity, Operational or otherwise), of the Well.
Integrity related tasks under the well integrity management section are as follows:
