Platform Installation Package for Aasta Hansteen Topside Transfer

SOLUTION:

We designed, engineered and manufactured two 120te Hydraulic Drum Winch packages for the project.  As part of the supply, we delivered a bespoke wireless control system which allowed the winches to be synchronised for simultaneous operations from the two locations. 

HPU CONTROL PANEL:

Each winch was controlled via the use of a PLC selected from the Siemens S71200 range of products within the control panel mounted on each winch HPU. This position allowed local control of the winches and selection between local and remote control.

NETWORK TOPOLOGY:

There were two means of communication between the vessels.  The first was a wireless connection that was used when the vessels were moving into position. The second was via a Profinet cable runningbover the Spar when in position for contingency measures.

CONTROL STATION:

Our overall control station was installed within the vessel bridge. This allowed the operator to control the winches from a centralised location combined mode has been selected on the relevant winch.

The control station included a HMI to detail all relevant information and status of each winch’s operating condition, including communication status of the full Profinet and wireless network.
