FLNG CARGO LOAD MANAGEMENT STUDY

HEC prepared an operability analysis to support the development of a new FLNG installation for an oil major.  Such facilities load LNG at a constant, near-steady rate and discharge to LNGCs intermittently. Therefore, this study included a statistical analysis of the projected time sequence of LNG quantity on board during an 11-year period to analyze the following:

• The static stability and longitudinal strength of the vessel during regular operation, including all standard and some non-standard production/discharge cycles;
• The total time spent with any one LNG tank in the sloshing zone (15% to 25% fill), as well as the longest single duration spent in the sloshing zone and when this might occur;
• The operational management of a typical production/discharge cycle to minimize sloshing exposure;
• The ballasting/de-ballasting rules will be applied during operation to optimize the production/discharge cycle.
