FLNG
FLNGs are floating production facilities where natural gas from subsea reservoirs is converted into liquid hydrocarbons to form a more practical means for storage transport.
MODEC FLNG
MODEC has high hopes for LNG as a major energy source of the future, and has established a new position in the sector with the development of its very own solution as well as other FLNG technologies.
- MODEC has multiple FLNG designs available to handle either dry or wet gas.
- In case of a wet gas FLNG, the LNG, LPG and Condensate are stored separately in different storage tanks.
- In case of dry gas, only LNG is stored.
- Depending on the quality of the gas delivered to the FLNG there might be a requirement for extensive gas pretreatment facilities.
- MODEC's FLNG solutions are based on both, converted hulls or new built hulls.
- An appropriate type of mooring system is selected depending on the prevailing environmental conditions and water depth.
- Various combinations of topside equipment are available depending on the specific requirements of each project.
- Liquefaction Process: N2 expander, SMR or DMR
Liquefied Gas Experience
While gaining unrivaled experience in over 40 EPCI projects of floating oil production facilities, MODEC has long been active in being involved in various projects that handle liquefied natural gas. MODEC has completed front-end engineering and design (FEED) works for actual FLNG projects, and are ready for EPCI work.
