      Tank construction method: Single tank on site

      - One or multiple XL tank(s) constructed on site - Carried out efficiently with our proprietary coil building system (one tank at a time) - When transport or installation on site is difficult or impossible How does single tank on site work? Transporting large tanks is often a challenge. Although many things are possible, transporting tanks by road or water is not always an (attractive) option. On some occasions, installation on a client’s premises is infeasible, such as when a tank needs to be hoisted into a plant building by crane, but there’s no access to allow it to happen. In cases like these, we can construct the tank on site. Our proprietary coil building system enables us to work efficiently on sites around the world – we produce the complete tank on site. Production A number of containers of material and machinery are transported to the location, together with the team (which includes welders). Once at the location, we set up our proprietary coil building system on site as the basis for the tank construction. Our machinery unrolls a stainless steel sheet for one hull section, cuts it to size and then welds it automatically. Once the first layer of the tank is complete, computer-guided hydraulic lifts raise the hull section so that the next section can be inserted in the same way. The tank is constructed step by step from the bottom. All work is carried out efficiently and at workable height.

    2. Tank Integrity Inspections

      Tank Integrity Inspections

      Flat bottom storage tanks can be found in on a broad range of locations. Varying from storage terminals to refineries to process industry. We offer services for owners, manufacturers and users. The assessments are supported by various NDT techniques, including floor scanning, UT, etc. KTN has these services available in house. Storage tank inspection according EEMUA or API standards includes inspection of the tank shell, floor and roof. NDT methods and techniques used for tank inspection include: ultrasonic testing, magnetic flux leakage, magnetic particle testing, dye penetrant testing and bubble leak/vacuum box testing. A tank floor scanner using the magnetic flux leakage technique is used for the initial scanning of the tank floor. Detected indications are verified using visual testing and ultrasonic thickness measurements. Bubble leak/vacuum box testing, supported by magnetic particle or dye penetrant testing, is used for testing the welds in both the tank floor and shell. The tank shell and roof, both external and internal, can be scanned using a remote access ultrasonic device. This has multiple benefits, of which the biggest is that there is no need for scaffolding. This makes the scanning process faster and decreases down time for the client. The information from all techniques is combined in the report to create a complete picture of the integrity of the tank.
