1. INTRODUCTION

1.1 General

Consortium PT Pelayanan Listrik Nasional Batam (PLNB) - PT. Universal Batam Energy (UBE) will

perform the development of new 16 Subsea Gas Pipelines system along the + 13.5 km from ORF

Pemping Island to Plant Gate of Gas Power Plant in Tanjung Uncang Batam. Which is refered toas Pipeline Section #2. For a long offshore pipeline approximately 12, 5 km and 1 km for the

onshore. As for the pipeline section # 1 will be constructed by PT Premier Indonesia as Gas Seller

which this pipe will be built with Hot Tapping sistem of WNTS existing line heading to ORF facilities

on the Pemping Island.

The first time this pipeline will transport the gas 40 MMSCFD respectively owned by PT PLNB and

PT UBE and will increased to 55 MMSCFD within 6 years after the first commercial date accordance

with Gas Sales Aggrement (GSA GSA # 3 and # 4). The Gas pipeline system is designed with

pressure 550-710 Psig at a received point with a gas maximum flow capacity 125 MMSCFD to meet

transportation needs in the future. The both parties will use any volume of this gas for its own interest

to drive the new gas turbine power plant, to be built in Tanjung Uncang Batam with an installed

capacity approximately 210 MW.

Location of the pipeline and associated facilities are illustrated in Figure 1-1 below:

Notes :

1. Diameter of pipework (drain, vent, balance, line, etc) shall refer to project P&ID

2. L = related to Pig Launcher, R = related to Pig Receiver

3. These lengths are extreme figures, based on data for presently available magnetic flux and ultrasonic tools. The extreme

dimension will be useful for conceptual design but the user should check the lengths of the latest available tools from

various relevant manufactures when performing detailed design since there are significant variations between tools

(particularly between magnetic flux and ultrasonic tools). Thus it may be decided to design for only one type of tool or the

use of temporary extension pieces for the major barrel could be considered.
