1.0 INTRODUCTION

The Shwe and Shwe Phyu fields are located within Block A-1 and the Mya field islocated within Block A-3 in the Bay of Bengal, offshore western Myanmar. Waterdepth varies across the Shwe and Shwe Phyu fields from approximately 90 m to 140m. For the Mya field, which is located to the south-east of Shwe field, the water depthvaries from approximately 140 m in the north to 950 m in the south. These fields lieapproximately 110 km to the north-west of Kyauk Phyu in Ramree Island, RakhineState, Myanmar. The Shwe, Shwe Phyu and Mya fields are essentially gas fields withlimited liquids present and low in CO2 and H2S. The development project for thesefields is referred to as Shwe Project and has 4 different phased development during

life of field.Daewoo International Corporation (Myanmar E&P) (DEP) is acting as Operator ofthe Shwe Project and the joint venture partners are ONGC Videsh Limited (OVL),Korea Gas Corporation (KOGAS) and GAIL Limited (GAIL). The Engineering,Procurement, Construction, Installation and Commissioning (EPCIC) work for thePhase 1 development of Shwe Project has been awarded to Hyundai HeavyIndustries (HHI).

In the Phase 1 development of Shwe Project, Shwe and Mya North fields will bedeveloped with conventional platform and subsea facilities. The produced gas fromeach field will be processed at the Shwe platform (SHP), and then will be transportedthrough a 32" diameter gas export pipeline, approximately 110 km long to an onshore

gas terminal (OGT) near Kyauk Phyu in Ramree Island, Rakhine State, Myanmar.

The Phase 1 development of Shwe Project consists of the following main elements:

One conventional jacket with the integrated drilling, production and processingtopside platform (SHP) at Shwe field in approximately 110 m water depth

One subsea manifold with five slots (inclusive of one spare) for 4 subseawellheads at Mya North in approximately 186 m water depth and about 12 kmaway from SHP.

One 14 flowline from Mya North to SHP (about 12 km long)

One 32 export pipeline from SHP to OGT (about 110 km long), which is

composed of offshore part from SHP to landfall (about 105 km long) and onshorepart from landfall to OGT (about 5 km long)

One onshore gas terminal including supply base (OGT) in Ramree Island

One jetty facility at Kyauk Phyu in Ramree Island

General notes:

1. If the second coat is not applied immediately after a zinc rich primer has cured, or if the primer is exposed to humid or outdoorconditions prior to application of the second coat, a epoxy tie-coat shall be applied on top of the primer immediately after theprimer has cured.

2. When this coating system is used for accessible deck areas, a non-skid aggregate shall be added to the second last coat.Prior to applying the coating where the non-skid aggregates are added, the primer and the succeeding coat(s) shall be appliedto a MDFT of 175 m and fully cured.

3. Chalking rating 1 (see Table 1) or better should be preferred for externally exposed surfaces.

4. Zinc rich primer shall be in accordance with ISO 12944-5.

5. Specialized coating systems with at least two coats and without zinc rich primers, may be selected for particularly exposedareas on installations provided the coating system is pre-qualified in accordance with 10.1, the coating thickness is > 1000 mNDFT and provided relevant successful field experience is documented.

6. Painting MDFT for inaccessible areas (if any) may be increased (up to 1.5 times MDFT of the applicable system) since theseareas will not be accessible later for touch up paint and re-paint during the platform maintenance periods. The applicability ofthis requirement shall be reviewed on a case by case basis depending on the selected Suppliers paint system.

General notes:1. The following is applicable to coating system no. 2A only: All metallized surfaces shall be sealed in accordance with the

following requirements: The sealer shall fill the metal pores. It shall be applied until absorption is complete. There shouldnot be a measurable overlay of sealer on the metallic coating after application. The materials for sealing the metal coatingshall be two-component epoxy for operating temperatures below 120 C and aluminium silicone above 120 C. Volumesolids in the sealers when applied shall be 15 % nominal.

2. The following is applicable to coating system no. 2B only: The intermediate coat and the topcoat shall have been pre-qualified as coating system no. 1. The pre-qualification may have been carried out at different film thicknesses. A tie coatshall normally be used unless demonstrated not to be beneficial to the overall performance. The tie-coat shall be inaccordance with manufacturers recommendation.

3. For items that will be welded after coating, 5 cm to 10 cm measured from the bevel area shall be left uncoated and 30 cm to40 cm measured from the bevel area shall be left without coating on top of the metal coating.

4. For insulated surfaces of tanks, vessels, piping and equipment operating at temperatures < 120 C, two coats of immersiongrade epoxy phenolic (each 150 m NDFT) may be applied as an alternative. MDFT shall be 300 m. Surface preparation

shall be as defined above.
