Our Services

Our company offers services in the field of design, assessment and inspection of technology equipment and pipelines for chemical, petrochemical and power engineering units. We also draw up inspections plans including methodology for evaluation of technical conditions. Everything we do for minimal probability of failure. We have a rich amount of knowledge in the area of thin-walled structures such as storage tanks, silos, pipelines, etc.

We provide structural stress analyses by using finite element methods (FEM) to customers who need highly-skilled and experienced consulting engineers to help perform analysis on their designs or they need to solve the structural integrity of their assets. Identifying and analysing possible failure modes and optimizing the ultimate design to prevent against them is the primary focus of our structural stress analysis services.

Our philosophy and advertising slogan is "Think simply, think innovatively", and we always follow it. We always offer unique, simple and innovative solutions to our clients.

How we do it

Each project requires a specific solution. Our workflow is exclusively focused on customer needs and usually consists of the following work phases:


Detailed preparation can save valuable time during the subsequent solution of project.


Understanding of the issues and familiarity with the analyzed problem.


Core part of each contract.


Communication with the customer during all stages of the project is necessary to achieve the projected aim.


Integration of final comment and hand in to customer.


Potential defence of result in front of an investors or supervisory authority.

Our Solutions

We offer own software solutions to support inspection and maintenance for a vast field of assets operations. Our software solutions are an integral part of structural integrity management that is fundamental to ensure safe and the most productive operational life of assets. Structural integrity analyses covers a full range of activities of inspection and monitoring, material evaluations and remaining life assessment, stress and fatigue analyses, remediation and repairs. Effective structural integrity management minimises the risk of catastrophic failure and the likelihood of having to take components out of service, maximises operational efficiency, and promotes asset life extension.

The framework of our software solutions is based on a fully web-based programme with offline application for android tablets. Core server executive programme with android application for management of on- or off- stream inspection and data collection are strong tools for effective assets inspection and maintenance.

Our software solutions are based on the combination of two approaches Risk Based Inspection (RBI) and Reliability Centred Maintenance (RCM).

Risk Based Inspection (RBI)

RBI methodology is a very flexible approach to planning and choosing of appropriate inspection activities of assets. It combines on the one hand the increasing demand for safety and reliability of structures, and on the other hand the economic requirement for effective planning, cost savings and economies of inspection structures of operators.

A key factor of RBI methodology is the correct assessment of probability of failure of the structure or component. It requires perfect knowledge of the degradation mechanisms. Also it is very important to correct classification of the potential consequences on safety, environment and operating losses of failure.

Reliability Centred Maintenance (RCM)

RCM is a technical tool created to preserve the inherent reliability of equipment by optimizing of maintenance activities to achieve the specified safety requirements, eligibility, availability and cost saving, in the context of the required operational safety. The RCM method identifies an activity for preventive maintenance to avoid or mitigate the consequences of a particular failure mode. The RCM method assesses the operational integrity as opposed to the RBI, which evaluates the structural integrity.

RCM is a unique method for determining the minimal safe maintenance activities that are necessary to ensure the proper functioning of technical systems.


ASTlife is developed software solutions to support inspection and maintenance of storage tanks and pipeline, including technology storage tanks terminal. It is a unique and innovative system solution for the management of inspections, monitoring service life and ecological aspect of operation of storage tanks, pipeline networks and mechanical equipment of storage tanks terminals. The program includes modules based on Risk Based Inspection (RBI) and Reliability Centred Maintenance (RCM) methods that meet industry standards and recommendations (EEMUA 159, API 653, R-111, UL 142, and others) are complemented by our own know-how.

The main aim of our company is to offer first-class software solutions that are tailored to the specific type of tank terminals and technology. A necessary part of implementation of the ASTlife is an RBI and RCM analysis and composition of the inspection programme/activities. There is also a design range of NDT inspection procedures and set guidelines for evaluation of the measured data. Our developer programme solution covered analysis of unconventional types of storage tanks as well.

We offer complex inspections support in the whole lifecycle of storage tank terminals. Our solutions are always tailored and covers vary kinds of storage tanks (above ground, buried, vertical, horizontal, cylindrical, boxed, etc.) and their various problems (settlement, vibrations, buckling, loss of stability, thickness optimization, etc.).

Jakub studied Steel Structures and Structural Mechanics at Brno University of Technology in the Czech Republic. He is an expert in structural stress analyses and residual life time assessment of steel structures as support for inspection and maintenance of asset. He is high qualified in using of FEM programmes RFEM and ANSYS. His strengths are an excellent ability to analyse the root causes of failures that is why he still very actively search for on-site experiences.
