present a deep
cooling water intake
solution that can help to
increase the efficiency of
FLNG facilities.
F
loating LNG (FLNG) facilities have
emerged as a solution for gas
field developments, especially in
remote areas with limited or no existing
infrastructure. Many of these offshore
fields are located in deepwater tropical or
subtropical areas, with surface temperatures
in the range of 25°C. As the liquefaction process has a considerable requirement for cooling water,
gaining access to lower temperature water in these areas could result in a large efficiency benefit.
Aker Solutions and Statoil have designed a large capacity water intake system for FLNG
facilities, fetching colder water from greater water depths.
By reducing cooling water temperature by 15 – 20°C, process efficiency will
increase substantially in a large FLNG development, improving the project
business case.
