Trelleborg Solutions for FLNG Ship-to-Shore System

 
The UTS transferred LNG from the Skangas-chartered LNG carrier Coral Energy to the onshore terminal at the Norwegian port of Herøya on October 7 and is now in full commercial operation. A ‘plug and play’ solution, the UTS requires no modifications to the LNG carrier – instead, the platform maneuvers offshore to meet a vessel, removing the need for costly and environmentally intensive dedicated small/medium-scale LNG vessel harbor and jetty structures.
 
The system consists of Trelleborg’s Cryoline LNG hoses, attached to a floating platform, which incorporates Trelleborg’s ship-shore link technology and a selection of its marine fender systems.
 
Vincent Lagarrigue, Director of Trelleborg’s oil and marine operation, commented: “The UTS shows that LNG infrastructure doesn’t need to be bound by the same thinking that underpins transfer solutions for fossil-based energy. Instead, it demonstrates how new ideas are creating the foundations for safe, efficient and convenient infrastructure that can keep pace with the rapid evolution of the LNG market, both as a power source and marine fuel.”
 
Magnus Eikens, Chief Commercial Officer of Connect LNG, added: “Trelleborg’s expertise in fluid handling and LNG transfer has made it an invaluable partner in this project. The Cryoline LNG hose is an integral part of this solution, thanks to its durability, flexibility, and safety features. What’s more, its ship-shore link technology and marine fender expertise is vital in supporting UTS LNG transfer operations.”
 
Richard Hepworth, President of Trelleborg’s marine systems operation, said  “The UTS is an important forward thinking development. Our Universal Safety Link (USL) and the Sea Guard and Super Cone fenders are used in many LNG applications already. Integrating them into such an innovative solution as this will help ensure the safe, efficient transfer of LNG into markets and locations that would have previously been considered uneconomic. We are proud to be part of a project that promotes the expansion of the LNG value chain.”
 
José Miguel Moreno, Director at Gas Natural Fenosa, commented: “The innovation demonstrated by Trelleborg and Connect LNG has delivered a game-changing solution for the LNG industry. We now have a market-ready system that opens a world of possibilities in the LNG small and medium scale business thanks to this collaboration.”

 

The UTS increases the operability of an LNG terminal, as the hose and platform can be retracted when not needed, or when harsh weather conditions would present hazards. The platform-based solution can either function as a standalone unit, or enhance a larger terminal’s ability to handle deliveries to and from a broader range of vessels. Trelleborg service engineers were present during the first commercial LNG transfer of 400m3, and will support further commissioning operations.
 
A range of Trelleborg technologies make this new model of LNG transfer possible. Cryoline is the first floating hose of its kind to receive the coveted EN1474-2 accreditation, using flexible rubber-bonded hose technology to minimize boil-off and withstand fatigue harsh environmental conditions. Extra safety is provided by an integrated monitoring system using fiber-optic technology.
 
Trelleborg also supplied its industry-leading USL 8810 to monitor the LNG transfer process. A triple fiber optic, five pin SIGTTO and pneumatic system was supplied to ensure all round flexibility for the platform for any visiting vessel.

Trelleborg’s Sea Guard fenders were specified for use at the front of the UTS to absorb berthing impact against the larger LNG vessel prior to attachment to the vessel. While to reduce the impact of the tug vessels on the UTS, Trelleborg’s Super Cone (SCN) fenders were specified to enable the tugs to safely push the UTS from shore into position for transfer operations.
