STUDY WAS PREPARED FOR PRE-FEED STUDY OF WEST JAVA FSRU

JAKARTA, 11 MARCH 2011

Assessment & Compatibility Study of FSRU Exemplar for an STS LNG Transfer with

LNGC Population in Market

Objectives

“…to build up confidence level to go with option STS”

“…to set up design parameters for further engineering process”

Compatibility of the manifold arrangements between 2 vessels i.e. exact location, spacing, height above waterline

Design mooring arrangement, i.e. length overlap, length off set between 2 vessels

Design parameter for Cryogenic Transfer hoses, Yokohama fenders, etc

Issues involved

Codes & Guidance's

Recommendations for Manifolds for Refrigerated Liquefied Natural Gas Carriers (LNG)

Mooring Equipment Guidelines

ICS, STS Transfer Guide (Liquefied Gases)

International Safety Guide for Oil Tankers & Terminals

STS LNG Transfer Guidelines

Four (4) different methods of STS LNG transfer

1. Double-banked adrift 2. Double-banked at anchor 3. Double-banked moored at a Gasport jetty 4. Double-banked moored to a Gateway STL buoy

Relatively less complexity compare to No. 1 & 2

What would be the designed arm length?What would be the min diameter of Yoko fender applied?

Data Ranges & Observation

Total 343 LNGC vessels data available for observation, updated by end of 2010 Range LNGC Capacity from 1,517 Cbm up to 266,000 Cbm Vessels delivered in 1969 up to vessels delivered in 2010 85% range data are intact, remaining are less intact Covering all types of containment systems Covering all Size Categories

Population of LNGC Fleet

The area of concerns would be in the population of LNGC with Spherical type Almost all of Membrane type LNGC, manifolds were located at amidships area

Population of LNGC Fleet

The area of concerns would be in the population of LNGC Cat. C, as probably giving more Length off-set Abt. 20 Pct of LNGC Cat. C operated in the market now are ageing Cat. B sizes are the common market size

Membrane type is dominating most of the LNGC operating in market nowadays (within productive ages), new vessels and new buildings are tends to build using this type of containment.

Population of LNGC Fleet

Population of LNGC Fleet

Even within the group of Moss type LNGC, the no of vessels with size of Cat. B (same category as FSRU) are dominating – similar sizing group will most likely compatible in dimension

Data observations

An Over-lap configuration

Where The bow of FSRU 32.3 m away overlapping LNGC bow line

(X)

An Off-set configuration

Where The bow of LNGC 25.76 m away overlapping FSRU bow line,for data observation purposes , value marked as minus (-)

(X)

Data observations

WLMHW Lad

MHW Ball

(Y)

(Y) is a gap (clearance) of heights between FSRU’s manifold from waterline at empty ballast and LNGC’s manifold from waterline at Laden condition, this called as the extreme condition

Data observations

Findings & Conclusions

• The maximum deviation in length (X) is 68 m Overlap and (–) 26 m Offsets

• The maximum gap out of the extreme condition is 1.8 m up to 17.75 m

• Only less than 5%, LNGC manifolds arrangement are designed not in accordance to OCIMF recommendation, it does means that the spacing gap between lines are likely not match with Exemplar’s

• Three (3) no of data's were put a side due to too small (out of range) i.e. Kayoh Maru, Shinju Maru, Pioneer Knutsen.

• Market domination is Membrane type LNG at Cat. B size.

Executive Summaries

1. Confident that STS LNG Transfer of Exemplar for West Java FSRU is a workable alternatives

2. Exemplar FSRU is likely compatible to most LNGC vessels in the market at 85% confidence level.

3. Set-up design parameters for Jetty structures & Berthing facility i.e.

a) Length offset / overlap in the range of (+/-) 26 m (beyond FSRU length)

b) Maximum gap (height clearance) is 17.75 m

4. Exemplar specification is a market common size & types.

5. A further risk assessment and vessel compatibility study still need to be done on a case by case basis on each and every STS individual planning
