Jettyless LNG transfer concept

This concept has been developed to enable the transfer of LNG from small- to mid-scale carriers to onshore or floating storage and regasification terminals where it is not feasible to construct a jetty for mooring the vessel. This may be because the water is either too shallow for the ship, or too deep for a jetty to be built.

DEVELOPMENT CRITERIA FOR THE CONCEPT

— To enable small- and mid-scale LNG deliveries to locations with no existing LNG infrastructure, where the water is too shallow for ships or a jetty is otherwise impractical — To enable LNG carriers to be moored using an economical four-point mooring system — To enable bunkering or reloading of ships — To enable delivery of clean fuel or modern and efficient Wärtsilä gas-fired power plants — To allow operations in environmentally sensitive areas

With the LNG carrier conventionally spread-moored in proximity to the shore, a self-propelled Floating Transfer Terminal (FTT) is attached to the ship using mooring ropes or winches. The FTT has been developed by Houlder in cooperation with Wärtsilä. The transfer arm, which is operated from the FTT, is developed by Houlder and KLAW LNG.

The transfer of LNG takes place using floating Cryoline hoses by Trelleborg. The Cryoline technology provides fatigue resistance in even the most demanding conditions, and enables a viable and cost-effective alternative to con-ventional jetty-based transfers. When not in use, the hoses are stored onshore with a custom designed reel system.

DIFFERENT CONCEPTS TO SUIT ACTUAL CUSTOMER NEEDSThe jettyless concept represents a low investment and quick installation solution in situations where the cost of building a jetty is prohibitive. Because each location has its own characteristics, Wärtsilä develops different concepts to suit the particular situation.

As an EPC contractor, Wärtsilä sees this new concept enabling even smarter total LNG terminal solutions for vari-ous types of small-scale LNG opportunities, where a jetty would be an expensive and time-consuming solution to execute.
