Call for interest – Fabrication & installation of rig materials

HERA members can you help? An essential objective of the AGGAT program under this research aim is the installation of a materials test rig on a geothermal site to investigate field-based geothermal scaling and corrosion. The data gathered in turn will accumulate into an industry owned information database to base future decisions on in terms…

First-party welding inspection to AS/NZS ISO 3834 and AS/NZS 1554.1 standards

For structural steel products to be free from serious problems in production and in service, it is necessary to provide a suitable level of quality management from the design phase, through material selection, into fabrication, and subsequently inspection. Requirements for welding/fabrication activities are given in the Code of Practice of the NZ Steel Fabricator Certification…

New Zealand engineering firm riding on the crest of wave energy – EHL Group

HERA member EHL provided the basis for US energy innovator Northwest Energy Innovations’ wave energy device, which was successfully deployed at the US Navy Wave Energy Test Site (WETS) near Kaneohe Bay, Oahu, Hawaii. The device, called Azura, will be deployed for 12 months of grid-connected testing as part of a rigorous programme to commercialise…

Notice – Temperature distribution in typical composite slabs under standard temperature-time fire condition

Temperature-time (T-t) curves and temperature contour plots due to the ISO 834 standard fire loading curve for typical New Zealand composite floors have been calculated and presented in tabulated format. The temperatures in 10 minute intervals up to the requested fire resistance rating have been reported for the slab top face and along the thinnest…

The evolution of the NZ steel industry – innovation dinosaur or drosophila?

We have an image problem. In experimental evolution, Drosophila (the humble fruit fly) is often used to demonstrate evolutionary processes. It is used because genetic changes for the fruit fly can be observed very quickly in response to natural selection. In business, the equivalent of the fruit fly is the IT or information technology company,…
