190Mtr3 Lime Saturator Tank
Scope of Work: Lime saturation tank fabrication (190 m³) with access platforms and components
Key Elements: Two-piece fabrication for transport, 1554.1 SP welding, MPI/UT NDE inspection
Project Details
DWW Engineering completed lime saturation tank fabrication for a 190 m³ lime saturator tank and associated access platforms and components as part of the Landers Shute Water Treatment Facility upgrade. Due to the tank’s size, we fabricated it in two halves to allow transportation to the painters and then to site, which required tight control to ensure both halves aligned correctly during fabrication and after welding.
We carried out welding to 1554.1 SP using approved procedures and qualifications, supported by magnetic particle and ultrasonic NDE inspection to verify weld integrity. The scope also included fabrication of the gantry bridge, circumferential platforms and access stairway to support safe operation and maintenance access.
