Kelly Tarltons – Life Support Systems Refurbishment, Auckland



As part of continued improvements at Auckland’s Kelly Tarltons Underwater World, H2O Engineering was awarded the contract to replace the facility’s sea water filtration system along with upgrades to the Ozone gas distribution and water chilling systems.
The scope included detailed design, installation and commissioning of each of the replaced or refurbished systems.

CONSULTING ENGINEERS: Thorburn Consultants

CLIENT: Hawkins Construction

The Kelly Tarltons plant room environment presented a unique challenge due to the moist salt air environment and space restrictions for new plant. Along with environmental considerations inside the plant room all the works took place while the facility and life support systems were in operation. Careful consideration of materials was required with every aspect of the project to ensure upgraded systems were robust enough for long term service.

  • Demolition and removal of redundant steel sand filter, cut into approximately 20 pieces in situ and removed from site.
  • Installation of 2 x 1400mm diameter fibreglass sand filters with automatic valve harness.
  • Installation of new Aquarium water chilling heat exchanger for the main aquarium.
  • Installation of a new Ozone gas distribution system throughout the facility, including connection to the three main life support systems.
  • Upgrades to water chilling systems on two operational life support systems.

All the contracted works were completed on time and budget during refurbishment works for the main facility aquarium in 2010.
