Single Point Mooring Hawsers
Single Point Mooring Hawsers are typically used in the Oil & Gas Industry whereby an Oil Tanker (or any ship) can be securely moored to an offshore Floating Production Storage Offloading Facility (FPSO), offshore Floating Storage and Offloading Unit (FSO), Tanker Buoy as depicted above.
Although typically used in the applications describe above, the materials and techniques used to make Single Point Mooring Hawser can be applied to manufacture Mooring Lines, Mooring Hawsers, Tow Lines, and Towing Hawsers.
Another application for Single Point Mooring Hawsers is for Ocean Floor Anchoring Systems. Deep Sea Mooring Hawsers are highly specialized, performance engineered, and manufactured.
