LNG Tanks PNS have had great success with LNG tank testing and commissioning, We are able to carry out hydro testing using our Hydro cyclone which filters the testing water to ensure minimum residue is left behind. For the pneumatic testing we are able to supply clean, dry and oil free air at high flow rates, it is often beneficial to carry out the tank drying at this stage.

The final stage is the oxygen freeing, PNS have a large selection of Nitrogen supply equipment to achieve this in the shortest possible timescale.

During all of these activities PNS can supply monitoring and data logging facilities to ensure accurate measurement and record keeping.

“PNS played a key role during the construction and commissioning of the Dragon LNG terminal, They delivered time and time again, often under difficult conditions. I have no doubt that the efforts by the Highly experienced PNS personnel contributed significantly to one of the most successful terminal start ups that I have witnessed and furthermore due to the commitment made during pre-commissioning we have not required any unplanned maintenance activities. I would welcome their assistance on future projects.”
