The return of the upgraded RV Tangaroa represents a huge advancement for New Zealand science and exploration

NIWA today welcomed home RV Tangaroa, New Zealand’s only deepwater research vessel, after a $20 million dollar upgrade to enhance its ocean science and survey capabilities.

They are silent, produce no emissions when operating and create electricity - they are photovoltaic (PV) solar panels. NIWA Nelson has just installed 56 Jiawei 185W solar modules onto its rooftop to generate electricity.

The scope of the EnergyScape (parent) project was subtly different to the hydrogen options and bioenergy options sub-projects, but all three projects had similar phases of work and applied similar methodologies during their development. Before addressing the methodologies used in the EnergyScape projects, we need to define two concepts:

Energy pathway - An energy pathway is the thread that connects an energy resource as it is supplied through various conversion and distribution infrastructures to the application demanded by an end-user.

NIWA worked with the community on the island of Totoya, in the Yasayasa Moala Island group in south-east Fiji to assess their energy security and energy related socio-economic opportunities.

About tidal energy in the Cook Straight.

Harnessing tidal power for electricity generation will be a landmark in broadening New Zealand’s already impressive renewable energy portfolio, a marine energy conference is to be told.

“In the drive to replace non-renewable fossil fuels with renewable energy sources, marine energy is emerging as a viable option in the near-future and a real complement to wind, geothermal and hydro resources,” says NIWA oceanographer, Dr Craig Stevens.

Wind is a renewable and environmentally friendly energy source.

We provide training in the use and maintenance of our instruments, software and data collection systems.

We offer service contracts to minimize downtime if an instrument fails. We keep a full range of spares in our Christchurch store and can courier a spare to the contract holder on receiving a request.

We evaluate new products to ensure that they're 'fit for purpose' before we approve them for widespread use.

We service and support individual instruments, systems and nationwide networks.

We install monitoring and control systems of all sizes, throughout New Zealand, in the Pacific Islands and even the Antarctic.

We supply a complete range of environmental monitoring equipment, from small components to large systems. We also supply accessories and miscellaneous items.

We manufacture items such as cables and circuit boards through to subassemblies for both standard and specialized systems.

We develop custom environmental monitoring and irrigation flow-control solutions.

We design instruments and systems of instruments. We have full mechanical and electronic CAD capability.
