The technology for cryogenic liquefaction and storage of LNG on an offshore floating vessel is known. However, the safe reliable ship to ship transfer of this LNG in an open sea, possibly harsh, environment has not been possible. SBM have experience in both the supply and operation of mooring systems and so put this experience to work in the development of a Tandem LNG Offloading system. The philosophy adopted for this development was to keep the design simple and, whenever possible, stick to components that had a known track record.

With over 40 years experience in the design, supply, and operation of Single Point Mooring (SPM) systems and Floating Production Storage and Offloading (FPSO) systems, the value of simple robust design was well understood and applied to this LNG Arm development. Known technology and operational experience either directly or indirectly applied to the Arm include soft yoke or gravity moorings, articulated fluid transfer arms, cryogenic swivels and tandem mooring systems. Additionally, experience from designs that must disconnect and reconnect in typhoon or ice areas has led to the understanding of structures and mechanical systems exposed to dynamic forces and motions, as well as the physics of making connection under these conditions. The LNG Offloading Arm detailed herein effectively combines this technology and operating experience to enable the offshore industry to effect the safe and reliable offshore transfer of LNG.
