Abstract
Abstract It was more than a decade ago that the visionaries of Project Azure predicted that possibly by 2004, a complete floating LNG chain could be built including floating FPSO (FLNG) and a floating LNG FSRU (Floating Storage, Regasification Unit), linked by LNG shuttle tankers transporting LNG from the FLNG to the FSRU. Today in 2014, the chain still does not exist. Although there are many floating LNG receiving terminals operating successfully around the world, the elusive FLNG has still not materialized. However, now that construction has started on Shell’s Prelude and Petronas’s PFLNG-1, realization of the vision of floating LNG chain is imminent. Many technology advancements have combined to make floating LNG chain a reality. Maturation of subsea well and control systems have mitigated the risks of subsea well operations. Proven glycol (MEG) and other regenerative hydrate management systems have allowed longer tie-back distance. Cost-effective mooring systems for large FPSO, flexible flow-lines and catenary risers have enabled floating system of FLNG size to be seriously considered. However, it is the advance of floating LNG technologies that have evolved over the past 20 years that finally tipped the risk-reward equation. Technologies such as offshore ship-to-ship LNG transfer, motion tolerant processing and rotating equipment, LNG spill and gas safety, and deep water cooling water lift systems have matured to an acceptable level. The rewards of FLNG are very compelling. Major cost savings can be achieved by eliminating: Well head/production platform(s)Processing platform to facilitate gas treating, liquids recovery and stabilizationFSO for condensate and NGL productsGas compressor and pipeline to transport gas to an onshore LNG plant and replace with a FLNG system located in the field. There are also the intangible cost savings such as efficiency gains by constructing the entire system in a ship yard, material and manpower logistics, and shorter project duration. In places where space constraint and regulatory restrictions make land-based LNG liquefaction and regasification difficult, FLNG and FSRU are cost-effective alternatives. This paper will present the economics drivers that make floating LNG chain attractive to producers and buyers alike, and the many conventional production technologies and those unique to FLNG that combined to enable FLNG chain to be developed with confidence. The realization of floating LNG chain will enhance the economics of LNG as a preferred fuel.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
