104236-FEED-OR-RPT-08-001-Rev.A Project Description
Introduction To meet the growing demand of energy in gas supply in Vietnam, “PVGAS Fast Track LNG Terminal (hereinafter referred to as the “Terminal”) Project” of Petrovietnam Gas Joint Stock Corporation (hereinafter referred to as “PVGAS”) (hereinafter referred to as the “Project”) is required to be constructed as soon as practically possible to cope with the shortage of gas supply. LNG will be unloaded, stored, pumped-up, vaporized and then metered to be sent to the gas consumers through the distribution pipeline network. Also the Terminal will function as a key center of energy supply. This document describes the outline of the Project.

General Project Descrip tio n
2.1 Site descriptio n The site locates at Cai Mep Industrial Zone, Ba Ria-Vung Tau province, Vietnam. The LNG Terminal facilities will be installed at PVGAS’s free land with the area of 50,000 m2 (200 m by 25 m) or PETEC’s free land with the area of 97,000 m 2 (250 m by 390 m) shown in Figure-2-1, and LNG carrier will moor at Thi Vai jetty or PETEC jetty. Some utility facilities and building such as Air compressor, nitrogen generation package, river water intake system, piping rack system, central control room, fire fighting system including pumps and main loop line, which are installed in the land for LPG project will be utilized as common facilities for both LPG and LNG terminal facility. Figure-2-2 shows the condition of Thi Vai river around the Terminal. This river has following features.
The river is narrow and the width of river in front of Thi Vai jetty is only 580 m.
There is sharp bent in the upstream side of Thi Vai jetty.
About 1,100 vessels with the size of 500 – 80,000 DWT navigate each month.
In this FEED following three kinds of plot plan are studied and prepared.
Case 1 : Plot plan of FEED Thi Vai jetty is used for receiving LNG carriers. LNG tank is installed in PVGAS’s free land.
Case 2 : Plot plan of basic design (Option 1) PETEC jetty is used for receiving LNG carriers. LNG tank is installed in PVGAS’s free land.
Case 3 : Plot plan of basic design (Option 2) Page 3 of 8 Tokyo Gas Engineering Co., Ltd. Tokyo, Japan

2.2 Facility descr iptio n The main function of the Terminal is to store LNG and supply the vaporized LNG to the customers through pipeline while a part of LNG is transported to the remote area with truck lorry. After LNG carrier arrives at the terminal, liquid phase unloading arm and line shall be arranged to unload the LNG to the storage tank by the unloading pump in the carrier. The maximum size of carrier to be considered is 75,000 m 3 in the case of Thi Vai jetty and 155,000 m 3 in the case of PETEC jetty. The size of LNG Page 4 of 8 Tokyo Gas Engineering Co., Ltd.

104236-FEED-OR-RPT-08-001-Rev.A Project Description
storage tank is planned to be 100,000 m 3 in the case of adoption of Thi Vai jetty and 180,000 m 3 for PETEC jetty as a result of tank capacity study in FEED. During LNG unloading, BOG is generated due to heat ingress into the cryogenic systems and physical replacement. A part of BOG is returned to the LNG compartment of the carrier through the gas phase return arm and return gas line to balance the pressure of the compartment; the rest of the BOG shall be re-condensed after pressurized by BOG compressor and mixed with low pressure and sub-cooled LNG. The re-condensed BOG together with LNG from the storage tank will be sent through high-pressure LNG pump. Then the LNG is heated and vaporized to gas phase by utilizing open rack vaporizer (ORV), finally pressure-adjusted and measured before sent to the pipe network. In future calorific values of send-out gas might be adjusted in calorific value adjustment facility for which future tie-ins and necessary area are reserved in initial phase. LNG can be also sent to the truck loading system by low-pressure LNG pump for LNG transportation by truck lorry. In future, ship loading to small ship with the capacity of maximum 6,500m 3 might be required for which future tie-ins and necessary piping arrangement is considered in initial phase. The project is planned to send high-pressure natural gas of design pressure 5-7.5MPaG.

The required primary functions of the Terminal include, but are not limited to, the followings:
Receive, maneuver and moor LNG carriers Analyzer of quality of LNG from LNG carriers Unload LNG from LNG carriers to LNG storage tank, and return LNG vapor from the Terminal to the carriers
Store LNG in LNG storage tank to provide sufficient buffer until next LNG carrier arrival and possible delays of LNG carrier arrivals
Handle BOG generated during unloading and from heat ingress during normal operation,
Pressurize LNG from LNG storage tank to LNG truck loading skids by low-pressure, and to vaporizers by high-pressure
Control the flow of natural gas to send-out pipeline to satisfy the contracted consumers requirements

The primary function required for the Page 7 of 8 Tokyo Gas Engineering Co., Ltd. Tokyo, Japan
Front End Engineering Design & Cost Estimation For PVGAS Fast Track LNG Terminal Project
104236-FEED-OR-RPT-08-001-Rev.A Project Description
Terminal is unloading, storing, transferring LNG by truck lorries and sending out natural gas into the pipeline distribution systems. The whole terminal facilities shall be designed to handle the amount of LNG, corresponding to the expected loading above mentioned. As the safety, reliability and quality of the Terminal and equipment are the primary objectives, Terminal facilities shall be designed to satisfy the LNG customer demands. Needless to mention, the unscheduled shutdowns of equipment should never compromise gas send-out availability to consumers. High overall Terminal availability shall be ensured by suitable redundancy of equipment and systems, and also by specifying that all equipment and systems must be designed to be well proven that they have been employed and operated with no problem over many years of operation in the LNG terminals worldwide. As a result, the design philosophy of the Terminal will ensure that no failure of any single equipment will result in total unavailability of gas send-out from the Terminal. As for the preservation of environment, the Terminal shall be designed and constructed to minimize the adverse effects on the environment. LNG source for the terminal has not yet been specified and the Terminal will introduce wide range of LNG including LNG based on Coal Bed Methane (CBM) and Shale gas. LNG from these sources shall be considered as design condition in order for maximizing the flexibility of receiving LNG.
6.
Permitt ing and licensing The Terminal design shall comply with not only the applicable codes and standards in Vietnam but also international codes and standards (hereinafter referred to as “Codes”). In case of conflict between the requirements of Vietnamese Codes and International Codes, order of precedence shall be as below: 1) Vietnamese Codes 2) International Codes In case of conflict exits among the codes and/or standards, PVGAS ask TGE to present the difference for resolution. Relevant safety, fire fighting, environmental protection of design should first satisfy Vietnamese codes, regulations and standards.
