End Client Chevron Australia / Direct Contract
Location Onslow, Western Australia
Commodity Oil & Gas
Project Value $8M / Primero Scope $2.5M
Solution Provided Civil, Structural Mechanical, Piping Electrical, Controls & Instrumentation works
As part of the Wheatstone DOMGAS processing facility development, Chevron Australia required the detailed design, fabrication, assembly and testing of a facility that meters and monitors the quality of the natural gas feed from the 200 terajoule per day domestic gas plant via a pipeline into the
The project scope included the combined full turn-key delivery of civil, structural mechanical, piping electrical, controls & instrumentation works and offsite testing & commissioning of the complete facility assembled in Perth prior to shipping to site.
The facility was assembled completely at Primero Groups workshop in Bibra Lake,powered up and given a complete IFAT testing regime prior to dis-assembling and packaging ready for delivery to site. Using its multi-disciplined delivery model Primero Group completed the works in-house and utilised our proprietary commissioning software system, ‘Checkmate’ to complete the electronic upload of commissioning checksheets in accordance with Chevron standards and specifications.
Primero performed the in-house hazardous areas verification and dossiers and the complete testing under supervision of Chevron commissioning teams.
RED GULLY GAS & CONDENSATE
End Client Empire Oil & Gas NL
Location Gingin, Australia
Commodity Natural Gas
Project Value $29m+
Solution Provided Procurement, Fabrication & Construction
Red Gully Gas and Condensate Processing Facility is located near Gingin Western Australia.
The processing facility consists of the development of two on-shore wells, Gingin West-1 and Red Gully-1, which feed gas and condensate through a processing facility that produces 8 terajoules/day of natural gas and 400bbl/day of condensate. With a strong background in hydrocarbon facilities and pipelines, and zero recorded injuries, Primero Group was engaged to construct civil works; detail, fabricate, deliver and install over 2,500m of piping; install gas processing equipment; and install electrical equipment and 25km of electrical reticulation, compliant to required hazardous area classification.
Primero Group proudly delivered the works within budget, schedule, and over 50,000 man-hours injury free. To support its client further, Primero Group developed the commissioning plan and completions procedures required for start-up and handover of the plant.
CARNARVON WASTE HEAT RECOVERY
End Client Enerji Limited
Location Carnarvan, Australia
Project Value $6m+
Solution Provided Commissioning Services
Enerji’s pilot Waste Heat Recovery Power Plant (WHRPP) is located in Carnarvon, Western Australia. The facility recovers waste heat off three gas turbine generators located at Horizon Power’s Carnarvon Powerstation. The WHPP consists of an organic rankine cycle generator and support systems.
Primero Group was engaged by Enerji to complete the commissioning of the facility through to handover. In addition to design improvements and management from Perth, a specialist team was mobilised to site to approach commissioning systematically and manage numerous stakeholders involved with the project (Enerji, Horizon Power, construction contractors etc). Primero Group was responsible for bringing the WHRPP on-line and synchronising it with the grid (supplying power). Primero is on target to successfully synchronise the WHRPP to the grid within the agreed schedule set by Enerji. Ongoing support will continue to ramp the facility to full production capacity.
PROJECT HIGHLIGHTS INCLUDE:
- Successful synchronisation of the WHRPP.
- Full stakeholder involvement during the commissioning works.
- On-going ramp-up support including modification works to piping and E&I systems.
MONDARRA GAS STORAGE FACILITY
End Client APA Group
Location Dongara, Australia
Commodity Natural Gas
Project Value $150m+
Solution Provided Detailed Engineering
Mondarra Gas Storage Facility is located in the Perth Basin near Dongara, which interconnects with both the Parmelia Gas Pipeline and Dampier to Bunbury Natural Gas Pipeline (DBNGP). The project scope was the design of a new gas storage facility that could store up to 15 petajoules capacity. This included increased injection and withdrawal infrastructure within the facility.
The development of the facility was a major strategic development in the shoring up of gas supply and minimizing any future supply disruptions. With a proven history of delivering design projects, Primero Group was engaged to provide the detailed structural engineering and design of the Mondarra storage facility as a sub-contract to the consultant, Momentum Engineering.
HIGHLIGHTS OF THE DESIGN INCLUDE:
- Detailed design & FEA analysis of all civil, structural & equipment layout foundations throughout the facility.
- Detailed design of pipe rack structures.
- Detailed design of fuel gas skids.
- Completed within the project schedule timeframes and delivered an economical design to the standards required
AGC GORGON UPSTREAM JOINT VENTURE
INLET ABOVE GROUND PIPING
End Client Chevron
Location Barrow Island, Australia
Project Value $8m+
Solution Provided Detailed Engineering
The Gorgon Upstream project ties the subsea components at two discrete fields (Gorgon and Jansz) to the onshore LNG plant via a system of pipelines and control umbilicals. The inlet lines consisted of 34 inch pipework along with various isolation joints, tees and valves.
Primero was commissioned by AGC to provide engineering and design support for their portion of the works, the inlet above ground piping. The on-site works were minimised by opting to complete pre-spooling and fabrication at the Australian Marine Complex (AMC). Primero designed integrated transport frames, a streamlined and economical approach to transport the 30 tonne sections from the AMC to Barrow Island.
The design consisted of 8 separated spools of different size and weight mounted to standard or super-racks. The super-rack option was preferred over conventional sea fastening as it limited interfaces with the dumb barge and provided transport flexibility. The solution was completed within project constraints with all frames successfully delivered to site.
