Covid-19 Alert Level 1
CSI wishes to congratulate NZ on our dedicated effort to mitigate COVID-19 allowing us to get back to Alert level 1. Remember to keep safe and Kia Kaha NZ.
Best regards, The Team at CSI
CSI was recently working at a Tank Farm in Tauranga where a replacement turpentine tank was going to be put in place. The Tauranga Tank Farm has 31 tanks that carry various substances such as class 3 flammable liquids.
Our team had to test the quality of the anchors that previously fixed down the bottom plates to the concrete slab to determine if they could secure the new structure to the foundation. The following case study breaks down in detail what the project required us to do, how we solved the problem and the outcome of the project. During this project, we used proof of load testing to determine the best outcome for our client.
The objective of this project was for a replacement turpentine tank to be securely attached to the previous foundation. The issue with the previous turpentine tank was that the base had rusted out. Oil and gas industries view corrosion in storage systems as a major cause of releases and equipment failure, so it was important that our test provided accurate results.
CSI was required to carry out tests that would determine the tension demand of the anchors.
We had to test the inserts for holding down bolts in the existing concrete slab. A new turpentine tank was going to replace the previous therefore the inserts in the existing slab needed to be tested to see if they had the strength to carry the new load. The engineer had to assess whether the connections would hold.
This project was carried out the following Testing Standards:
• Proof testing to BS 8539
• Proof load 100 KN
• Monitored movement Test
• Test carried out under the CFA Guidance Notes
And used the following test equipment:
1. 60 Ton Hollow Ram
2. Calibrated Digital Pressure Gauge
3. 2 Speed Hydraulic Hand pump
4. 3m Hose and Couplers
5. Reaction frame
6. Mitutoyo 543782 Plunger Dial Indicator (for monitoring)
7. Fine adjustment linear magnetic base (for monitoring)
