The arrival in July 2010 of two new 58m Putzmeister 5-stage boom pumps on Barrow Island, 60 kms off the mid-WA coast, heralded the start of construction works by CB&I on the Gorgon LNG tank bases.
Meales’ operators promptly and enthusiastically put the two machines to use.
The additional reach of the 58m Putzmeisters has been perfect for this project, as it has allowed all sections of these enormous tank foundations to be poured from the end of the boom with no additional hose. As a result, the pour rates for the high-strength concrete have been excellent and large pours have been completed in a timely fashion.
To coincide with the start of vertical wall pours, the arrival of a third 58m boom pump is expected in coming months. All three long-reach booms will then be kept busy pouring wall sections of 700m3 per pour.
At the completion of the walls, a Putzmeister MX36 placing boom will be mounted to pour the roof segments.
