During last year Verwater Singapore jacked 3 tanks at the Singapore Refining Company. Tank sizes varied between 54 and 79 meter diameter. 

The largest tank was an external floating roof which was supported by us during the tank bottom replacement and foundation reinstatement works. The second tank was a column supported roof tank which roof and tank bottom both were completely removed and replaced by new ones. The third tank was jacked with the aluminium dome roof in place. This required special attention on the lifting steps during jacking to avoid any disturbance to the aluminium dome.  

In all three cases the tanks were re-levelled in such way that both edge settlement and out-of-verticality were corrected in the most favourable way. A successful project with our local partner on SRC.
