Project Year > 2019 - 2020

Beach Energy redevelopment of the Katnook Gas Processing Facility (KGPF). The project site is in the Otway basin adjacent to the Ladbroke Grove Power Station in South Australia, approximately 40 km North of Mount Gambier.

DMK Engineering completed three major project portions along with numerous supporting packages. The largest being the supply and fabrication of pipe support structures, the fabrication, testing and coating of all process piping and the supply of labour, equipment and materials for installation of all structural, mechanical and piping components at the site.

Project scope and highlights:

  • Pre project cleaning, hydrostatic testing and local support for intelligent pigging / scanning of existing well to plant flow line piping.
  • Fabrication and surface treatment of Pipe Supports
  • Fabrication of stainless steel, carbon steel and A333 Grade 6 low temp spec piping, including heavy wall 500nb Sch 100 process spools.
  • Surface Treatment of Carbon Steel Pipework
  • Over 1400 fully traced welds, including tracking of field welds for piping installation.
  • 1400+ welds Visual, Magnetic Particle, Radiographic and Ultrasonic inspection and testing, zero project weld failures detected.
  • Refurbishment of project process tanks, volume up to 150kL, including on-site and off-site decontamination, tank modifications, testing, coating and return to site.
  • Provide labour for on-site flange management, and support of specialised hydrostatic testing services and prestart commissioning.
  • Provide specialised administrative resources to support on site principal contract and information management.
  • Provide services to construct / install well yard piping and equipment. Including connecting flowline piping.
  • Apply specialised coating system, and coating integrity testing on buried flowline piping at plant, and well head connecting piping and several flow line field dig up repairs.
