SMP Mechanical and Electrical Commissioning on Wheatstone LNG

Project Overview

The massive Wheatstone LNG Project, located 12km west of Onslow, in the Pilbara region of West Australia, commenced construction in November 2011. The expected total investment to completion for the project is A$29 Billion, bringing with it considerable economic benefits for the region including the creation of 7,000 jobs to date, and over $200 Million in contracts awarded to local businesses. Over $250 million has been committed to social and infrastructure projects which include health, education, recreation services and facilities, as well as road, power and water infrastructure. Supplied by the Wheatstone, Iago, Julimar and Brunello offshore gas fields, the liquefaction and export plant will have an annual capacity of 15 million tones, making it the fifth largest LNG plant in the world.

Scope of Works

EnerMech were tasked with the provision of an extensive Electrical and Structural Mechanical Piping (SMP) personnel solution for the pre-commissioning and commissioning of the two condensate storage tanks with a capacity of 120,000 cubic meters per tank, and two LNG full containment storage tanks with a capacity of 150,000 cubic meters per tank. Working with a number of blue chip clients at a key stage of the project, speed of mobilisation was critical.


EnerMech commenced work in July 2015. As a leading specialist in Electrical and Mechanical commissioning and pre-commissioning works on some of Australia’s largest Oil and Gas projects, EnerMech were able to quickly mobilise a team of over 150 experts in varying project critical and supervisory roles.

Electrical personnel included Supervisors, Engineers, Permit to Work Coordinators and Electricians. This was complimented by a team of Mechanical personnel including LNG Tank Welding and Module Superintendent, Supervisors for SMP delivery including welding, piping, scaffolding, modules and LNG tank, Engineers, Painting Inspectors, Boilermakers, Specialist Welders, Riggers and Machinists.

Rounding out a complete personnel solution for the project were QA Managers and Coordinators, Plant and Equipment Mangers, Planners and Supply Chain/ Logistics Coordinators.
