I want to know the answer to the following question:
The final investment decision for what was finalized by Royal Dutch Shell in May 2011?
All the background I'm provided with is that "FLNG technology is based on liquefied natural gas (LNG) developments that were pioneered in the mid-20th century and facilitates the exploitation of untapped natural gas reserves located in remote areas, often too small to extract any other way.". Is that enough to answer the question?
