The access system for oil platforms and other off shore installations that enables personnel to reach operational and accommodation spaces safely from the sea level. The system has been launched by the Norwegian specialist Selantic Safety AS. It comprises a foldable and retractable staircase (hoisted by motor and cable drum) which is stored on board the platform when not in use. The upper interface section may be either a swinging davit, a fixed frame for vertical launch/hoist, or a derrick crane working as a drawbridge. The staircase itself is a spiral foldable ladder with aluminium steps encircled by a Kevlar net for safety.
