OFFSHORE LIFTS FPSO roll presents new challenge for Alimak

Latest offshore application for Alimak's rack and pinion technology is a lift system for an FPSO vessel. The lift must operate in 13 degrees pitch and 24.5° roll. To handle these movements, a guide rail was incorporated on the opposite side of the car to the lift mast. This, along with the rack and pinion drive, ensures that the lift can operate at any of the angles caused through the rolling of the vessel.

The problem of very little headroom at the top landing was overcome easily, as no lift room or load bearing shaft is required with the Alimak lift. Machinery is housed on top of the car. The lift is 30 metres high with a capacity of 1,000 kg, and features a Comprack control system and VFC soft start/stop.

Since 1974, Skelleftea-based Alimak has supplied over 500 lifts to production platforms around the world.
