The world's northernmost natural gas liquefaction plant -
Hammerfest LNG on the island Melkøya, 800 km north of
the Arctic Circle near Hammerfest in Norway - passed its
performance test in August, exceeding the expectations.
The highly efficient plant produces now with a capacity of
up to 109% of the design capacity. Overall, Statoil and Linde
make a positive assessment of the project, the companies said.
After the revision shutdown in 2011, the performance test
has now been completed. The results show that all performance
guarantees for example related to product quality, capacity,
and energy consumption were clearly met.
In particular, energy consumption for the liquefaction
service was reduced significantly below the guarantee values.
Hence, the Hammerfest LNG base load plant now is also
officially the worldwide most energy efficient LNG base load
plant, according to the companies.
The plant is a unique technology project of the European natural gas and EPC
industry. The LNG base load plant with a capacity of 4.3
million tpy of LNG is based on a liquefaction process, jointly
developed by Statoil and Linde, that is optimized for the
arctic conditions, the so called Mixed Fluid Cascade (MFC).
With the successful commercialization of this novel process
and Linde's complementary process solutions for warm climate
zones, for the first time a proven European LNG technology is available for the
growing LNG market, the companies said.
With its established solutions for small and mid-scale LNG
plants and its future-oriented developments of floating LNG
plants, Linde has access to a comprehensive portfolio of LNG
Hammerfest LNG combines multiple innovative, environment-friendly and pioneering
elements. Due to limited plot space available and difficult construction conditions the plant
was designed very compact and modular.
The heart of the plant is the central process module with a
weight of 35,000 tons. This largest ever built LNG plant module
was pre-fabricated in a Spanish yard as a floating module and
has been transported 2.700 nautical miles to the island
Moreover, Hammerfest LNG uses for the first time an
efficient, environment-friendly direct sea
water cooling system which is suitable for arctic wheather
conditions. Trend-setting features also include the complete
separation of CO2 from the process gas and its reinjection into
a reservoir under the seabed as well as the realisation of a
flareless plant operation.
With the objective to enhance plant availability for the
first time in a world-scale LNG plant all main compressors are
With the successful development and realisation of
this LNG technology in a world-scale plant Linde has
established its universally applicable, European technology alternative in the LNG
market, said Dr Aldo Belloni, board member for Linde.
Melkøya is for us from both a technical and a
strategic view a valuable reference project."
