Donut International Ltd, design and manufacture the Donut personal controlled descent device. Originally developed for offshore installation abandonment when conventional escape is unavailable, Donut is also used for derrick, crane, and wind turbine escape, both onshore and offshore.

Donut is a simple, lightweight, tertiary means of escape, enabling individual controlled descent once attached to a load-bearing structure. It is easy to use, highly portable, and requires minimal physical effort to operate, unlike many alternative escape systems.

With no mechanical moving parts, Donut offers unmatched reliability and cost effectiveness. Each unit is designed to last the lifetime of an asset. A global training and Safety Assurance Testing (SAT) programme ensures all Donut unit owners are properly trained and their units can be SAT-tested locally. Deployed globally for over 30 years, Donut is recognised as the industry standard in personal escape.
