Didon FPSO Hook-up Complete

Mooring Systems Ltd successfully installed the permanent storage tanker FPSO Didon onto the TCMS® mooring system offshore Tunisia in September 2007. The system completes the latest stage of the field development. Last year PA Resources (field operator) installed a new production jacket. The crude oil is exported via a subsea pipeline, connected by a flexible riser to the tanker.

PA Resources asked Mooring Systems Ltd to come up with a temporary solution to continue production in the field, while their permanent tanker was in Malta dry dock for essential maintenance and the installation of the bow loading system. The engineering work scope for the TCMS® and mooring system was completed by Rig Engineering Ltd.

The 35te anchors were laid by the MV Normand Master, connected to 1500mts of chain. Once the system was connected to the bow of the tanker MV Melide, a 300mt 6” Flowline was connect to the import chute on the bow.

The chain was loaded in Norway. The spooling equipment, riser, hose guides, and installation equipment were loaded in Montrose at MSL‘s quayside facility.
