EEHA Inspections of Modules in South Korea

Project Overview

The Gorgon Gas Project is the largest single resource development in Australian history, comprising 18 gas wells, providing gas to the Barrow Island gas treatment and liquefaction facilities via a series of subsea gathering systems and underground pipelines. The destination plant consists of 3 liquefied natural gas (LNG) trains, with a combined capacity of 15 million tonnes per annum.

In order to meet demanding construction timelines Gorgon are implementing a Pre-Assembled Rack (PAR) modules construction system, where huge components of the LNG Processing plant are preassembled off-site and delivered to Barrow Island, where they are put together like massive building blogs. There are 52 PAR’s scheduled for delivery to Barrow Island, with some as large as 6000 tonnes.

PAR’s are shipped from Hyundai Heavy Industries’ Ulsan Shipyard in South Korea, the largest of its kind in the world.

Scope of Work

EnerMech EPS were tasked with the fast deployment of a team of EEHA Specialists to Korea to perform EEHA inspections. The team were required to perform over 1,800 inspections on a number of modules to ensure they were up to Australian Standards, specifically, Electrical Installation Inspections and Maintenance in Explosive Atmospheres AS/NZS 60079.17 and Electrical Installations AS/NZS 3000:2017 prior to shipment to the Gorgon Project in Northwest West Australia.

The modules were also required to comply with Gorgon’s strict Protecting People and the Environment policy for the project, a specialised set of protocol designed by ecologists and independent experts to protect Barrow Island’s unique biodiversity and minimise impacts on native flora and fauna. Compliance includes ‘wash-downs’ of each module prior to shipping to ensure no foreign or destructive elements are introduced to the island during the construction process.

The project objectives were essential to meeting to construction milestones on Barrow Island, resulting in cost savings for the client.

Solution

Cementing EnerMech EPS’s reputation for fast responsiveness to client requirements, a specialised team of 10 EEHA Instrumentation specialists were mobilised within an extremely tight schedule. EnerMech EPS overcame significant logistical complexities which included securing appropriate visas, and organising flights and transport to ensure client deadlines were met.

The highest safety standards were adhered to at all stages in line with client and EnerMech EPS policy. The language barrier was addressed via Korean to English language cards which were distributed during inductions. Project planning required the supply of suitable clothing and equipment to deal with cold conditions on site.

Wash downs and other planned works were performed on the modules and as such EnerMech EPS staff scheduled their inspections in unison to respond to project requirements, ensuring labour was effectively utilised at all times to meet and exceed project timeframes.

Achievements

The inspections were safely carried out to the highest standard while still meeting or exceeding all project milestones despite often challenging conditions. Successful project completion culminated in significant cost and time savings for our client.
