The project requirement was to design a steel grillage to support the Ampelmann A-04 offshore access system on board a specially modified vessel.
The Ampelmann A-04 system was designed to enable personnel to be safely transferred from a vessel or barge to a fixed or floating structure and does so by the use of 6 hydraulic cylinders which makes the system self-stabilizing and capable of compensating actual heave motions of up to 2.5 metres.
