Shell’s giant floating liquefied natural gas plant (FLNG), the Prelude, moved closer to production last week when she received a cool-down cargo from the LNG carrier Gallina.
The 70,000 dwt Gallina transferred a load of LNG to the Prelude on Wednesday and Thursday as the plant prepares for commissioning. It was the first time that Prelude has had an LNG carrier alongside to test the plant’s sophisticated loading arms.
Prelude is now testing its systems in preparation for first gas from Shell’s Prelude field, which holds an estimated three trillion cubic feet of natural gas (in combination with the adjacent Concerto field). Royal Dutch Shell hopes to begin generating revenue from the multi-billion-dollar project sometime this year.
Prelude has a nameplate capacity of 3.6 million tonnes per annum (mtpa), approximately the same as a single export-size liquefaction train built on shore. Her construction cost is believed to be in the range of $10-12 billion (and perhaps more).
Analysts say that Prelude will be an important test of the economic viability of the FLNG concept. Onshore plants have room to spread out and to grow, but the same equipment must be packed into a tight space if installed on a ship, adding complexity and raising cost. Shell has chosen not to exercise its options for more FLNGs like Prelude.
