Safer, low-cost containment system for valve actuators realises 90% cost saving

Industry context

Actuators are automated devices used to open and close valves. They contain huge amounts of potential energy. ​If they break, the powerful springs inside them can eject components at high velocity, which undoubtedly can cause significant injuries and damage equipment.

Project overview

The Fail-Force Actuator Safety Gauntlet by Infinity Oil Services – similar to a bullet proof bag – can be fitted over actuators which have fallen into poor condition offshore, making them safe for personnel and infrastructure.

The Actuator Gauntlet is made of layers of Kevlar, inside a water-tight, UV-resistant bag. It is intended for single use, but the material could be recycled (depending on the level of damage caused by an actuator blowout).

NZTC supported the development of the design through to certification and trial. This included the manufacture of a prototype, which was then tested and approved by Lloyds Register.
