We provide storage tanks integrity services based on our in-depth industry knowledge, operational expertise, knowledge of leading technical inventions, local regulations and our customer specific requirements. On each project we work closely with our customers to understand what their technical and business needs are. We are good at listening and during our conversations with clients we determine the best way for a successful solution. Our team is prepared for future serious challenges to improve customers’ business. We are prepared to be your storage tanks integrity partner.
We identify areas for improvement in asset integrity for our clients. Our priority is to be proactive it means that our solutions are innovative and cost-effective, resulting in increased operating profit and safe and extended storage tanks operating lifetime. Our services generally includes on- or off- stream visual inspection and assessment according to codes API 653, EEMUA 159 or STI, evaluation of non-destructive testing (NDT) measurements, fitness for service (FFS) tank assessment according to API 759, BS 7910 or R6 procedures, and detailed repair plans. Our team also has vast experience with specific storage tanks that are not covered by EEMUA 159, API 653 or other standards. We have done several structural analyses of boxed, horizontal and buried tanks. We can draw up tailored inspection processes based on local services conditions, local regulations and knowledge of structural mechanics of thin-walled structures.
We are also highly skilled in storage tank design, especially with structural and stability analysis. We are good at structural stress analyses by using finite element methods (FEM) that are inseparable part of our analyses and decision making processes. We provide support for the constructor at the design phase. We also perform technical supervision during construction of storage tanks.
Storage tanks services range
What we are unique in
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.).
For analyses of storage tank integrity we combine two approaches. The first one is based on deep knowledge of codes and standards. And the second is based on finite element detailed analyses for assessment of critical part of structures.
Assessment of the minimum acceptable thicknesses of each part of storage tank, generally depending on density of medium, climatic and operational loads, but load capacity of storage tank is also influenced by uneven settlement and other imperfections. For detailed analysis of structural integrity of structures and components we provide structural stress analyses by using finite element methods.
We provide for our customers simulations and redesign of storage tanks for changes of storage conditions (different density of products, height of filling, etc.).
We are a highly skilled team that provide to our client supervision and consultancy activities as a third party independent member. We have extensive experience that are helpful, time reducing and money saving to our clients. We are very effective in the solving of failure problems connected with operation of storage tanks. We are enthusiastic to find the cause of failures and to suggest corrective actions.
Fitness-for-service assessment is a multi-disciplinary engineering approach that is used to evaluate structural components to determine if they are fit to continue operation for some desired future period. In our company we have developed several procedures for evaluation of storage tanks components, such as nozzles, manholes, etc. We provide fitness for service tank assessment according to API 759, BS 7910 and R6 procedures.
We have vast experience with analyses of aboveground and buried horizontal tanks. These types of tanks we assess according to UL 142 standard or in-house made procedures. For stress analyses of shell and saddle supports we use FEM. We providing redesign of storage tanks for changes of storage conditions (different density of products, different height of filling, etc.).
In our company visual inspection is provided by highly skilled and experienced mechanical engineers which they have the ability to assess structural integrity of storage tanks, pipelines and facilities for safe operation.
We met many atypical storage tanks such as boxed shaped, double bottomed, buried, etc. that are not covered by commonly used EEMUA 159 and API 653 standards. These storage tanks needs tailored inspections plants. Our team is able to draw up full RBI study and form appropriate on/out service check lists.
Buried storage tanks have several advantages such as constant temperature environment, minimal threat of brittle fracture, etc. But these kind of tanks need a different inspection approach. Due to minimal possibility of inspections during tank operation it is necessary to increase criteria of the checking of secondary indications of tanks leakage or failure.
The combination of our knowledge, experience with structural stress analyses by using finite element methods gives us the ability for analyses of any kind of storage tanks. Identifying and analysing possible failure modes and optimizing the ultimate design to perform against them is the primary focus of our structural stress analysis services.
