MB Century offers a team of geothermal steam field process and piping design engineers, project managers, and computer aid designers (CAD). Our real strength comes from our in-depth experience and knowledge of the development of steam fields in New Zealand and South East Asia. 

We have an emphasis on the development of steam, hot water and two-phase pressure pipework and vessels. Our capabilities extend to steam venting systems and pump evaluation and specifications for hot steam/water duty. Our engineers and CAD team utilize Autopipe, NozzlePRO, Powerdraft, Microstation, and PlantSpace to produce integrated models and stress analysis calculations for all design work. Our designs go through a rigorous review process internally and externally to assure all industry codes and standards are met. MB Century’s quality system is ISO 9001 compliant.

The project management team works seamlessly with our fabrication and manufacturing business to produce integrated design build projects that are executed to a high industry standard on time and within budget. We continually work to improve our process and execution.


  • Miraka (Mokai) Clean Steam Supply (Design/Build) - this project supplies clean steam to a dairy processing plant. Our design is both leading edge and innovative. All vessels and pipes were designed and erected by MB Century.
  • Rotokawa 140MW NAP power plant. Design and built of production and reinjection Steam field piping.
  • Lihir Gold Steamfield Development and Anti Scalant Pump Skid - Newcrest is based in Papua New Guinea. This project involved designing and building a portable and fixed, specialist anti-scalant pump systems to control build up in geothermal wells.
  • Kawerau TOPP1 binary power plant. Design and build of steam and water connections including a new separation plant (SP30) and well connection..
  • Mighty River Power Rotokawa/Mokai – we provide ongoing support for the steam field across shutdowns and well reconfigurations in a pressured, and time driven environment.
  • Te Mihi Steam Field Design - this project involved additional development to the Wairakei Steam fields for Contact Energy. Following on from this we will support the Te Mihi Power Station as it proceeds.
  • Wayang Windu Unit 2 Steamfield Design, Indonesia – Steam field design and construction support to Star Energy/REK..
