How it works

Whether specified from the ground up or retro-fitted to existing tanks, ONGUARD offers performance, protection and peace of mind.

Unlike traditional tank anchorages that only work in a one-pull, tension manner, ONGUARD anchors provide controlled yielding in both tension and compression throughout an earthquake and its aftershocks.

Traditional anchors are also prone to fail after a single earthquake pulse. The energy-dissipating element within each ONGUARD anchor acts like a seismic fuse, meaning it can be it can be quickly, easily and cheaply replaced once it has done its job.

Technical

During an earthquake the ONGUARD anchors prevent the tank from overturning by holding it down whilst dissipating seismic energy through yielding of the anchors.

Traditional - The Past

Traditional illustration2

Traditional liquid storage tank anchors permanently elongate during an earthquake event which means the tank can rock unanchored and in an uncontrolled manner resulting in a severely buckled and damaged tank and contents

ONGUARD - The Future

ONGUARD seismic tank anchors yield and shorten in tension and compression in a controlled manner, keeping the tank under control and it’s contents protected.

Our Products

The key elements of the ONGUARD system are the patented energy-dissipating seismic anchors. These are manufactured in New Zealand to exacting standards and using a range of materials, each specifically selected and certified for its performance and durability. This hardware is provided as part of the ONGUARD system and is packaged and shipped to you, your contractor, tank supplier or installer.

Detailed drawings, methodologies and specifications are provided to assist with installation and set our standards for quality. The product is designed to cause little impact to your operation or tank aesthetic. Installation of ONGUARD anchors is considered to be simpler and cheaper than most traditional systems, and needs no specialist training, however ONGUARD representatives or partners are always on hand to provide technical advice before, during and after installation.

Our Services

ONGUARD is an integrated system of tank, anchorage, foundation, and connected infrastructure. We take a lead role in the design space, bringing together other partners and professionals to ensure each part of the system works in structural harmony with the others in order to maintain our promise of protected tank and protected product.

This design is conveyed in the form of detailed design documentation and specifications produced by ONGUARD and its partners. ONGUARD delivers this through excellent communication and the use of tried and tested technical, administrative and logistical systems as part of an end-to-end service.

ONGUARD staff oversee installation to maintain quality assurance and ONGUARD offer a 3-yearly inspection schedule to guarantee the system’s readiness to deal with a seismic event.
