The Extended FSU Mooring system (EFM) enables conventional STS operations and provides the option to select one of Stena’s multiple terminal configurations for floating storage, transfer, regasification, power production and/or ammonia cracking.

Extending the length of the vessel; the prefabricated EFM structure ensures a robust heavy-duty spread mooring system, keeping the storage vessel safely, permanently moored and secured at location also during extreme wave and wind conditions.

Complete Front End engineering design (FEED) including extensive scale model testing has been completed. The EFM design has been verified by Class and full Class approval has been obtained. 

The EFM can be installed expeditiously with moderate vessel modification time required in a yard thanks to the prefabricated EFM structures.
