Stranded Gas Field Applications
Stranded gas field applications, as the name suggests are typically located a
significant distance from existing offshore (or onshore) production facilities
or pipeline networks. Traditionally, such applications could only have been developed
using new build offshore production platforms and long distance pipeline tie-backs
to onshore facilities.
Now however, the advent of floating LNG producer vessel technology means that
such fields can be readily developed, both faster and more CAPEX efficiently than
the traditional model. By utilising the FLEX LNG LNGP, production of LNG will
be possible onsite and LNG offloaded to LNG shuttle vessels using a side by side
Associated Gas Field Applications
Associated gas applications provide an opportunity to monetise surplus gas production
at source in the form of exported LNG, while minimising/eliminating flaring or
gas re-injection from the host production facility. Capturing the flared gas
adds economic value to an existing project, and provides an additional benefit
to the environment by reducing emissions. Such applications typically involve
the mooring of the LNGP adjacent to existing fixed or floating production facilities,
with the export of the surplus gas to the LNGP via a pipeline network.
Early Production System and Staged Development Applications
Floating liquefaction offers a fast-track project compared to an onshore plant.
For the FLEX LNG LNGP, the development time from project definition until first
LNG is approximately 50% of the time required for a traditional LNG development.
Hence the LNG Producers are capable of providing a viable alternative for an early
production scheme generating revenues and creating value while the standard facilities
are being approved and built.
Building a smaller scale floating liquefaction plant has also proven to be less
capital intensive than a larger plant and onshore developments. By utilising several
medium scale LNG Producers, a large staged project, both onshore and offshore,
would see greatly improved economics, lower technical risks and a better fit to
the field production curve.
For developments where there is already an existing gas pipeline infrastructure
such as an existing domestic pipeline grid, the LNG Producer can be located in
a near shore location providing a scenario similar to onshore LNG plant, but with
a significant costs savings to CAPEX and accelerated development schedule.
Deepwater gas fields/long tie-back distances
For deepwater developments with significant distances to tie-back into existing
infrastructures, LNG Producers offer a viable solution to monetise the field at
Onshore gas fields
FLNG can offer a cheaper, quicker, and less complex solution for onshore gas
fields where there is little or no existing infrastructure such as Papua New Guinea
and CBM projects in Australia.
