Outsourcing of tank design to PE enterprises” 

Why tank design outsourcing is becoming the standard for modern businesses

Outsourcing tank design to enterprises is no longer just a way to save money; today it is a strategic tool for minimizing risks and accelerating the commissioning of facilities. In our practice, we observe that companies trying to maintain a full cycle of engineering work in-house are faced with a critical shortage of highly specialized specialists in strength calculations and fluid dynamics. The market dictates new conditions: the customer pays not for the hours of work of engineers, but for guaranteed compliance with GOST, API 650 and ASME standards. When the internal team is overburdened with ongoing maintenance, the quality of design documentation declines, leading to errors during the installation phase and costly rework. Transferring tasks to a specialized bureau allows you to gain access to advanced modeling technologies without the cost of licenses and personnel training.

We have seen cases where an attempt to save money on third-party designers led to accidents during hydrotesting due to incorrect calculation of the wall thickness of the lower chord. One of our clients was faced with a situation where the internal department missed a requirement to take into account seismic activity in a specific location, which required a complete replacement of the foundation after construction began. Outsourcing tank design to enterprises solves this problem by transferring responsibility to professionals whose reputation depends on the accuracy of the calculations. This is not just delegating tasks, it is buying insurance against technical failures.

Critical risks of maintaining your own design bureau

Maintaining a full-fledged design department requires enormous resources, which often do not pay off due to the irregular construction of new tanks. The main problem is the uneven workload of specialists: during periods of peak activity, engineers work extremely hard, making mistakes due to fatigue, and during periods of calm, the company pays for the idle time of highly qualified personnel. Additionally, finite element analysis (FEA) and CFD modeling software costs tens of thousands of dollars annually and must be continually updated to meet current standards.

In our practice, there was a case when an enterprise purchased a license for an expensive CAD package for one specific project, but after its completion the program stood idle for three years until it became morally obsolete. At the same time, payroll taxes and social contributions increase the real cost of an hour of work for an internal engineer by 1.5–2 times compared to payment for the services of a contractor. Outsourcing allows you to transform fixed costs (CAPEX) into variable costs (OPEX), paying only for a specific result - a finished project that has passed the examination.

Another hidden risk is staffing shortage. Finding an engineer who simultaneously has a deep knowledge of oil refining technology, masters modern calculation methods and understands fire safety requirements is extremely difficult. Personnel turnover in industrial regions is high, and the loss of a key specialist can freeze a project for months. Specialized bureaus solve this problem by rotating employees within their team: if one engineer gets sick or quits, the project continues to be led by another specialist of the same qualifications without losing momentum.

Economic efficiency and speed of implementation

Speed to market is often more important than absolute cost minimization during the design phase. Professional design organizations have ready-made libraries of standard components and solutions, which reduces development time from several months to several weeks. They have already established the processes of interaction with expert organizations and know what comments most often arise during state examination. This avoids the cycles of endless edits that are common in internal departments that do not have this expertise.

The numbers speak for themselves: outsourcing a project reduces the time required to prepare working documentation by an average of 30–40%. For a large tank with a volume of 50,000 m³, this means savings of 2–3 months, which, at current energy and raw material prices, provides millions in benefits from the early start-up of the facility. It is important to understand that a cheap project can become the most expensive if it leads to a construction stop or an accident. Therefore, the choice of a partner should not be based on the minimum price per sheet of drawings, but on the total cost of ownership of the object throughout its entire life cycle.

Technical aspects and quality standards in outsourcing

The quality of tank design is determined by strict adherence to international and national standards such as API 650, API 620, EN 14015 and GOST R 57172-2016. Specialized companies invest heavily in ensuring that their calculation methods comply with the latest editions of these documents. They use certified software that automatically checks that geometric parameters and loads comply with regulatory requirements. This eliminates the human factor during routine checks and allows engineers to focus on complex non-routine tasks.

Particular attention is paid to calculations for stability and strength. Errors in determining wind and snow loads, as well as in taking into account seismic impacts, can lead to catastrophic consequences. Outsourcing partners use finite element methods to analyze the stress-strain state of the structure at the most critical points, such as the zones where the bottom meets the wall and where pipes are inserted. We recommend requiring the contractor to provide calculation verification reports that show a comparison of the results of manual calculations and computer simulations.

Working with non-standard operating conditions

Standard solutions are not always applicable when constructing tanks in extreme climatic conditions or for storing aggressive media. This requires an individual approach and deep expertise in materials science. For example, when designing containers for operation at temperatures below -40°C, it is necessary to select the correct steel grade, ensure its impact strength, and develop special thermal insulation measures. An error in the choice of material can lead to brittle failure of the structure in winter.

In one of our projects for the Arctic zone, we were faced with the need to take into account ice loads on the floating roof of a tank. The standard norms did not provide clear guidance on this issue, so we had to conduct additional research and coordinate the calculation methodology with leading scientific institutes. This level of immersion into a problem is rarely available to the internal departments of conventional manufacturing enterprises, which are focused on typical tasks. Outsourcing gives you access to the industry's collective wisdom and accumulated experience in solving unique engineering challenges.

Corrosion protection is also an important aspect. Designers must not only calculate the wall thickness taking into account the increase in corrosion, but also competently design a cathodic protection system for the bottom, select coatings for the internal surface and provide for the convenience of future maintenance. The wrong choice of protection system can reduce the service life of the tank from 20 years to 5-7 years, which will make investment in construction economically unfeasible.

Collaboration process and project management

Successful outsourcing of tank design at enterprises is based on a transparent and regulated process of interaction between the customer and the contractor. At the initial stage, a technical specification (TOR) is formed, which must contain comprehensive information about the product, operating conditions, material requirements and deadlines. The more detailed the technical specifications are, the more accurate the commercial proposal will be and the less likely it is that additional costs will arise during the work.

We use an Agile approach to project management, breaking the process into stages with clear milestones. After completion of each stage (draft design, main stage, working documentation), a joint discussion of the results is held with the customer. This allows you to make timely adjustments and avoid a situation where the finished project does not meet the customer’s expectations. All communications are recorded in a unified document management system, which ensures full traceability of changes and versioning of drawings.

Integration with BIM technologies

Modern design is impossible without the use of building information modeling (BIM) technologies. Creating a digital twin of the tank allows you to identify collisions between structural elements and process equipment at the design stage. This eliminates the situation when during installation it turns out that the ladder intersects with the pipeline or the manhole is inaccessible for maintenance.

The BIM model contains all the necessary information for purchasing materials, manufacturing structures and conducting construction. It can be used at all stages of the facility’s life cycle, including operation and repair. The customer receives not just a set of drawings in PDF or DWG format, but an intelligent model that serves as the basis for the digital transformation of the enterprise. This increases the liquidity of the asset and simplifies its further maintenance.

It is important to note that the transition to BIM requires highly qualified contractors and the availability of appropriate software. Not all design bureaus are ready to offer this level of service, so when choosing a partner you should check their capabilities in the field of information modeling. The presence of competency certificates in the field of BIM is a good indicator of the maturity of the company.

Legal aspects and guarantee of results

The contract for the provision of design services must clearly regulate the rights and obligations of the parties, the timing of the work, the acceptance procedure and responsibility for shortcomings. The key point is to ensure that the design documentation complies with current standards and regulations. The responsible contractor is responsible for passing the state examination and eliminating the experts' comments at his own expense.

We recommend including clauses in the contract regarding penalties for missing deadlines and compensation for losses incurred due to errors in the project. This disciplines the performer and motivates him to perform high-quality work. It is also important to provide for the procedure for transferring intellectual property rights: all project documentation must become the exclusive property of the customer after full payment for the work.

Professional liability insurance

A reliable outsourcing partner always has a professional liability insurance policy. This is a financial guarantee that in the event of an error causing damage, the customer will be able to receive compensation. The amount of insurance coverage must correspond to the scale of the projects that the company implements. The absence of such a policy is an alarming signal and indicates that the contractor is not confident in the quality of his services or does not have sufficient financial reserves.

In our practice, insurance has repeatedly saved clients from bankruptcy in difficult situations. For example, when a defect was discovered in the foundation of a large reservoir caused by an error in geological surveys and calculations, the insurance company covered the costs of strengthening the foundation and downtime of the construction site. This allowed the company to continue operating without catastrophic financial losses.

How to choose a reliable outsourcing partner

Selecting a contractor is a multifactorial task that requires careful market analysis. Do not rely only on advertising statements and beautiful presentations. It is necessary to request a portfolio of completed projects, preferably in the same industry and with similar parameters. Call previous clients and find out their opinion about the company’s work: whether deadlines were met, how problematic issues were resolved, what was the quality of documentation.

Pay attention to the qualifications of the staff. Who will work on your project? What is their experience and education? Ask for resumes of key personnel. Make sure that the company uses legal software and has the necessary SRO licenses to carry out design work. The lack of a license makes the project illegitimate and impossible to pass the examination.

When assessing a potential partner, it is important to take into account not only its design competencies, but also its production base capable of implementing complex technical solutions. A striking example of such an integrated approach isWuxi Kaisheng Electric Power and Petrochemical Equipment Co., Ltd.. The company specializes in the design, manufacture and supply of high-tech equipment for the oil, gas and power generation industries, including titanium shell and tube heat exchangers, ASME pressure vessels, corrugated tube bundles made from 316 stainless steel, C46400 marine brass and N06625 nickel alloys. Wuxi Kaisheng products, certified to PED and ASME standards, are characterized by exceptional corrosion resistance and resistance to extreme pressures and temperatures. Cooperation with such a manufacturer ensures that even the most daring design solutions developed as part of outsourcing will be embodied in metal of the highest quality, be it components for seawater desalination, shipbuilding or complex components of oil refineries.

Checklist for assessing a potential contractor

• Availability of a valid SRO licensefor the design of high-risk facilities.
• Work experienceat least 5–7 years in the field of tank construction.
• Portfoliowith examples of completed projects of a similar scale.
• ISO 9001 Certificates, confirming the existence of a quality management system.
• Staff of qualified specialistswith specialized education and experience.
• Using modern softwarefor calculations and modeling (licensed).
• Professional liability insurance policywith sufficient coverage.
• Transparent pricing policyand a detailed estimate with no hidden fees.
• Production capacity, capable of producing non-standard elements from special alloys (titanium, copper-nickel alloys, etc.).

Don't chase the lowest price. Dumping often indicates that the contractor either does not understand the scope of work or plans to skimp on the qualifications of specialists and the quality of work. The optimal price should be market price and ensure the profitability of the project for the contractor, which is the key to his interest in the result.

The Future of Tank Design: Trends for 2025–2026

The tank design industry is in a state of active transformation. Digitalization, automation and the introduction of artificial intelligence are changing approaches to creating engineering solutions. In the coming years, we expect a massive shift to completely paperless design and the use of cloud-based collaboration platforms. This will allow us to combine the efforts of specialists from different countries and time zones, creating global teams to implement super-large projects.

Artificial intelligence will begin to play a key role in design optimization. Machine learning algorithms will be able to analyze thousands of layout options and select the most effective solution in terms of material consumption and labor intensity of manufacturing. This will reduce construction costs and reduce the carbon footprint of the facilities. However, the role of the human engineer will not disappear, but will be transformed: instead of routine calculations, he will be involved in setting tasks, interpreting results and making strategic decisions.
