Autonomous Transfer System

The Jetty-Less Autonomous Transfer System (ATS) meets the industry's demand for lower cost and more flexible LNG import and export transfer solutions.

The ATS unit contains all the required equipment, systems and safety features normally installed on a jetty, making the ATS fully autonomous. It can be adapted for all LNG carriers from small distribution / bunker vessels to the largest existing LNG carriers. Designed to cope with wave conditions, the semi-submersible unit ensures high operational regularity, and requires low operational expenditure, as no propulsion, additional large machinery or manpower between loading operations is required.

Self-propelled with hose-handling crane in-built, the ATS can operate both connected to shore and connected to an offshore installation (FSU or similar).

A 'Plug & Play' Solution

The ATS system is a complete “Plug & Play” LNG Transfer System that requires no modification of existing assets plus minimal interface with the FSU, onshore facilities or existing jetty.

One of the key advantages of the ATS solution compared to other systems, is that all LNG transfer equipment is built into the ATS. The hose reels are also located on the ATS unit, eliminating the costly construction of separate hose reel platforms and providing positional flexibility.

In further contrast to other similar Jetty-Less solution providers, the ATS is equipped with a hose handling crane for lifting and handling of the aerial STS hoses between the ATS and the midship manifold of the visiting LNG carrier (covered by the approved US patent).

The main interface is standard flange connections from the floating LNG hoses meaning no major modifications to the onshore facilities, FSU or existing jetty are required.

A complete ATS unit - with hose reels - can be constructed, commissioned and fully function-tested at the construction yard before the unit is transported to the final project location. Installation time at the final location is reduced to days.

Built for Safety

Utilising a deck mounted spread mooring system, the ATS enables a distance of 150m or more between an LNGC and an FSU.

Advantages:

Significantly less cost than keel mounted spread mooring
Less FSU hull modifications and reinforcement required
Optimized mooring catenary chains enables installation in shallow water
All mooring FSU chains termination are visible, providing confidence to operators
Optimized for the new innovative and cost effective in-line tensioning mooring solution
