Project: Underbase for Offshore Turbine

Final Location: Pegaga Gas Field Development, Malaysia

Timescale: – July/August 2019

Rilmac Fabrication were contracted by a global engineering concern to build three high-end underbase fabrications for use on an offshore gas platform.

Due to the exacting nature of the project all key stages of the fabrication and welding processes were witnessed by a third-party inspection body (ABS).  On completion of the fabrication work the underbase was finish machined by Rilmac’s machining partner ADA Machining of Ashton -Under Lyne.

As these underbase will be used offshore, surface preparation and painting were key for this project.  The underbase fabrication were prepared to ISO8601-3: P3 and finish painted to meet ISO12944:5 ASM.06, a three-coat system with a durability of over 15 years. The painting system is approved to NORSOK MS01 System 1 Ref. ERO024159-98. All stages of the preparation and painting were inspected by NACE level 3 inspectors.

The first completed fabrication was packed and loaded onto a flat rack for shipping to Houston USA.  Timing was critical to ensure the agreed sailing requirements from London Gateway were met.  Once in Houston the completed underbase will be package with the gas turbine and generators before being shipped to its final destination in Malaysia, where it will be used on the Pegaga Gas Field Development project.
