   FPSO & FLNG CURRENT STATUS……

CURRENTLY @ 100+ FPSO’S UNDER OPERATION
.ONE FLNG PLANT UNDER EPC AND COUPLE OF THEM UNDER FEED / CONCEPT STAGE .MAINLY ONSHORE TECHNOLOGY & PLANT DESIGN CONCEPT APPLIED TO SHIP.
ENGINEERING WISE POSSIBLE TO IMPROVE WITH INVOLVEMENT OF ESTABLISHED .ENGG COMPANY HAVING BOTH OFFSHORE & ONSHORE EXPERIENCE
.NEED TO INVOLVE MODULE SUPPLIERS HAVING ENGINEERING BACKGROUND TO ENSURE TROUBLE FREE MODULE TIE UP & OPERATION ON THE SHIP .CURRENTLY THE FLNG CONCEPT OF FULL LAND BASED PLANT BEING FIXED ON FLOATING HAS SOME CHALLENGES TO ADDRESS ISSUE RELATED TO SLOSHING MOVEMENT, INTER SHIP TRANSFER, OPERATION OF PLANT DURING ROUGH WEATHER CONDITION ETC

Worldwide need for clean burning fuel


Shortage of large fields near shore leads to high project cost.

The cost escalation has led to floating LNG production on a vessel (FLNG)
A way to develop stranded gas fields, isolated, remote from land and other Infrastructure
c)    Alternative to flaring and re-injection
d)   Alternative to land-based Greenfield LNG-plants
e)   Market uncertainty
Improved technology in LNG storage & transfer (sloshing and motion effects)
FPSOs are conventional, over 100 in operation
Hundreds of offshore gas fields over 0.5 trillion cubic feet, suitable for 1 – 2 MTPA FLNG.

FUTURE PROSPECT & GROWTH…
DEMAND FOR 150 MILLION TON PER YEAR OF LNG BY 2012
POSSIBLE TO HAVE A MEDIUM SIZE FLNG WITH CAPACITY OF 1 TO 2 MILLION TON PER YEAR REQUIREMENT OF LIQUEFACTION VS CNG TO BE EVALUATED (NOT ECONOMICAL FOR DISTANCE LESS THEN 3000 MILES)


CHALLENGES IN DEVELOPING FLNG PROJECTS
There are a number of issues that need to be carefully examined when considering a floating LNG facility
• Location & sea condition
• Survival in storm conditions
• Ensuring smooth facility operation in motion & rough sea
• Suitable sites having available large quantity of Gas which can be trapped subsea
• Availability of skilled manpower to build & operate, material and equipments / package modules suitable for operation in marine environment, suppliers, Certifying agency…..
• Whether we really need such huge FLNG terminals or whether a smaller version can be more productive and economical
• Access for export / import vessels (tugs & pilotage)
• Type of plant, liquefaction / regasification
• Type of vessel & containment
• Mooring of the facility
• Method of transfer of cargo
• Deck congestion
