1.0 INTRODUCTION

1.1 GENERAL PROJECT DESCRIPTION

Lam Son JOC was established following a Petroleum Contract being signed between

Petro Vietnam (50%) and Petronas Carigali Overseas Sdn. Bhd. (50%) on 7th January

2003, providing for Lam Son JOC to conduct petroleum exploration within Blocks

01/97 & 02/97 which are the relinquishments of a Petroleum Sharing Contract (PSC)

for Blocks 01 & 02 signed in September 1991 between Petronas Carigali Overseas

Sdn. Bhd. (85%) and Petro Vietnam (15%).

1.2 LOCATION

Thang Long is geographically located in the south-western part of Block 01/97 &

02/97 in the Cuu Long basin (see Figure 1.1) approximately 120 km east of Vung

Tau, 26 km south of Ruby field and 35 km northeast of Su Tu Vang Field. The oil

was discovered by 02/97-TL-1X well (June, 2004) in the Lower Miocene and Lower

Oligocene sandstones. Dong Do is approximately located 5 km southeast of Thang

Long. The oil was discovered by 02/97-DD-1X (May, 2007). Water depths across the

block range from 60m to 70m. There were total 06 wells drilled in Thang Long -

Dong Do field.

Figure 1.1: Thang Long - Dong Do Field

1.3 FIELD DEVELOPMENT

The development plan calls for a central processing facility located on an FPSO with

production from the two fields via dry trees only. As such two wellhead platforms will

be tied back; one located on Thang Long the other on Dong Do delivering full well

stream transfer to the FPSO as shown in Figure 1.2.

Figure 1.2: Development Schematic

The FPSO will be located 2.84 km from the Thang Long WHP and 2.0 km from Dong

Do WHP.

Unprocessed fluids from the wellhead platforms will be transferred to the FPSO where

the crude will be dewatered and stabilized to meet a tanker loading specification.

Associated gas will be used to provide fuel for the FPSO and lift gas for Thang Long

and Dong Do wells with the balance exported to a near-by gas export pipeline.

Produced water will be treated prior to discharge overboard.

3.0 PILE DRIVEABILITY ANALYSIS

Pile drivability analysis has been carried out using the GRLWEAP program based on

the wave equation analysis concept with the soil data of the geo-technical report

“Geotechnical Investigation report for BH-DD WHP, DONG DO LOCATION

OFFSHORE VIET NAM” – No AGSB/116/SI/09/SGN(B).

3.1 DESCRIPTION OF DRIVEABILITY ANALYSIS

Pile drivability analysis employing wave equation is used to compute the pile driving

stresses and to predict blow counts based on soil resistance to driving, quake, soil

damping, pile section and segment length, hammer properties (driving rated energy,

hammer efficiency).

In wave equation analysis, pile is subdivided into segments of approximately 1.0m in

length. In order to cover the variety of soil resistances, various Soil Resistance to

Driving (SRD) is input for investigation of anticipated driving (dynamic) stresses

acting throughout the entire pile length.

3.2 LIMITATION OF PILE STRESS

Limitation of pile stresses during pile driving of a free standing pile is in accordance

with API RP 2A WSD:

• The combination of stresses due to the dynamic impact of hammer and dead load

of hammer and pile shall not exceed the yield stress of the material.

• The maximum dynamic stresses shall not exceed 90 percent of the yield stresses.

• Pile refusal is considered when blow count exceeds 300 blows/ft (1000 blows/m)

for consecutive five feet (1.5m) as per API RP2A clause 12.5.6.

3.3 SOIL RESISTANCE TO DRIVING

Skirt Pile drivability analysis is carried out to ensure the pile drivability

performance, despite for pile make up verifications and as guidelines for pile

installation. The analysis is not intentionally aimed to predict the blow counts

accurately.

In this one dimensional wave equation analysis, the driving stresses and predicted

blow counts are governed by the input SRD values taken from the geotechnical

report.

The static soil resistances can be estimated based on the followings:

• API static soil capacity for unplugged condition = ( ) ( ) upcisrsr AqAFAF +∑+∑ 0

• API static soil capacity for plugged condition = ( )pcsr AqAF +∑ 0



Page No.: 10 of 49

Where,

Fsr = Unit skin friction calculated based on remolded shear strength

qc = Toe resistance at the pile tip

Ao = Outer pile shaft area

Ai = Inner pile shaft area

Ap = Plugged pile end bearing area

Aup = Unplugged pile end bearing area

The estimated SRD for continuous driving and soil set-up cases for either plugged or

unplugged pile can be taken as per PLEM Design Basis, Document No.: TLDD-

0003-4JAW-A01-0001.

Three (3) pile driving cases are considered in the analysis described as follows,

a) Continues driving case

Estimated SRD equals to 0.6 API static capacity.

b) Soil set up case - Lower Bound case

Assuming restart condition up to 12 hour delay, the estimated SRD is 0.9 API static

capacity.

c) Soil set up case - Upper Bound case

Assuming the delays of few days, the estimated SRD is taken equal to API static

capacity.

The skin friction on the inside wall of the piles is considered for the continuous

driving condition as per point a) above. The end bearing component of driving

resistance is assumed to be less than static end bearing as recommended in PLEM

Design Basis and assumed to be acting on the annular tip area.

After delays depending on the delay duration, the internal friction is assumed to

result in plugged driving, hence plugged condition is considered for the restart

condition. The end bearing component of driving resistance is assumed to be equal

to or less than static end bearing and assumed to be acting on the gross tip area in

accordance PLEM Design Basis..

4.0 PILE MAKE-UP DESIGN

4.1 PILE UP-ENDING

The calculation results are shown in the report TLDD-0003-4JAW-A07-0001

“PLEM Foundation Design” – Section 4.5.

4.2 PILE STICK-UP

The maximum pile stick up length at different installation stages is calculated to

ensure that the acting stresses are within the allowable stress limit during stick-up

above the pile guide. The maximum permissible stick-up length along with pile self-

penetration with and without the hammer system is used to predict stickup length

from the skirt pile guide.

During pile driving operation, the following stress check applies for pile stickup

section:

• Static stresses are compared with allowable stresses as per API-RP-2A.

• Combined stresses = (Static Stresses + Dynamic Stresses)
