SBM Offshore is proud to announce the industry's first fully qualified and certified offshore LNG transfer system - the Cryogenic Offshore Offloading and Loading (COOLTM) system.

The COOLTM system is comprised of a flexible cryogenic floating LNG hose and connectors designed to allow the transfer of LNG between vessels in a tandem moored configuration, i.e. in exactly the same way that traditional floating oil and gas facilities carry out cargo transfers. SBM Offshore has also completed the qualification for the manufacturing of the COOLTM hose. The COOLTM system has achieved a Certificate of Design Assessment by ABS and a Certificate of Fitness for Service by DNV, reflecting satisfactory results of tests carried out according to the requirements of EN 1474-2 Standards.

SBM Offshore has a long history of setting the pace for technology development in the offshore energy sector. The COOLTM system is the latest achievement in our ongoing mission to meet the changing needs of our clients with fit-for-purpose solutions. The COOLTM system allows for reliable and safe offloading of LNG in tandem from a Floating LNG production vessel (FLNG) to an LNG carrier. It can also be used for importing LNG onto a floating LNG storage and re-gasification unit (also called an FSRU).

"The COOLTM system fills a key technology gap in the offshore LNG business" said Mike Wyllie, SBM Offshore's Chief Technology Officer. "SBM Offshore has, with its partners, already developed leading technologies for floating production of LNG as well as floating LNG storage and regasification. The COOLTM system now allows us to deliver to our clients a full LNG loading or offloading transfer system as well, using the industry standard set-up of tandem mooring and floating hoses".

Before the COOLTM system, open sea offloading of LNG cargoes to offtake carriers in a side-by-side configuration was only possible in benign environmental conditions. But because of potentially harsh sea conditions in some locations where floating LNG production vessels are being planned, the ship-to-ship transfer of LNG requires a tandem offloading configuration. In 2005, SBM Offshore began the development of a cryogenic transfer system for this purpose.

Tandem offloading is standard practice for traditional FPSOs, using a floating oil offloading hose string. This system has contributed to the global growth of floating production facilities over the last four decades. Thanks to our large fleet of floating production assets, we have almost 200 years of accumulated FPSO operational experience in which we have performed over 5,000 offshore offloading operations for crude oil, condensates and LPG.

The COOLTM system will be a key component of future offshore Floating LNG Projects. By enabling tandem offloading of product from the FLNG vessels using a floating hose system, we have enabled a step change in the safety of this critical LNG transfer operation. This system will also allow FLNG projects to be considered in harsher locations without excessive downtime due to offloading system availability, and with significantly reduced risk.

SBM's COOLTM hose design is based on a patented system, and comprises a well proven outer marine hose with an inner composite LNG hose. The space between these two hoses is filled with insulating materials which have excellent properties over the full range of ambient to cryogenic temperatures. The COOLTM connector consists of both a structural and a fluid connector. It is a cryogenic quick connect/disconnect system that handles and connects the COOLTM hose to the LNG Carrier bow manifold and therefore facilitates LNG loading and unloading. The fluid connector component has been jointly developed in conjunction with our partner FMC Technologies. Together, these new technologies enable the safe and reliable transfer of LNG in difficult offshore environments.
