1.0 INTRODUCTION 1.1 Project Description

The Bien Dong 1 Project involves offshore development of the Hai Thach and Moc Tinh gas/condensate Fields in Blocks 05.2 and 05.3 approximately 340km south of the coast of Vietnam. The fields lie approximately 20km apart.

The project includes: A Wellhead platform in Moc Tinh (WHP-MT1) A Wellhead platform in Hai Thach (WHP-HT1) A Production and Quarter Platform in Hai Thach (PQP-HT) A Floating Storage and Offloading (FSO) vessel in Hai Thach An in-field pipeline from the WHP-MT1 to WHP-HT1

Condensate export lines from the PQP HT to the FSO

A fuel gas line from the PQP HT to the FSO

A gas export pipeline from the PQP HT to link up to the existing Nam Con Son pipeline.

Submarine Cable from the PQP HT to the WHP-MT1.

The FSO design will be conducted under a separate contract.

2.0 SCOPE 2.1 General

The preliminary heat load estimation of the heating, ventilation and air-conditioning (HVAC) systems for Bien Dong; Moc Tinh Wellhead Platform (WHP MT-1) is documented in this report. The HVAC systems were simulated using Carrier E20-II Rev.4.30 software of which heat load analysis is based on the AHSRAE transfer function method. The cooling capacity generated by this software provided the coincident peak load calculated on an hourly basis over a period of 12 month.

The areas covered in the analysis include:

o 24 man Living Quarters

o Electrical & Instrument Building

- Electrical & Instrument Room

- Battery Room

- HV Switchgear Room

- Transformer Room

Notes :1 Required exhaust air flow shall be either calculated exhaust air flow based on air change per hour or minimum outdoor air requirements based on ASHRAE Standard 62.1-2007 requirements, whichever is larger.

2 Total outdoor air required shall be based on fresh air required for human for Living AreasReference from ASHRAE Standard 62.1-2007 "Ventilation for Acceptable Indoor Air Quality", Table 6-1; Minimum Ventilation Rates in Breathing Zone

3 Formula for Exfiltration Flow Rate :Q = 0.839 * 1000 * Area * sqrt(diff press.) - ASHRAE Applications 51.5

4 Required ventilation air shall be based on either directly exhausted air plus exfiltration air or outdoor air required based on ASHRAE Standard 62.1-2007 requirements, whichever is larger.

5 Conditioned supply air shall be selected based on minimum required air change per hour per room or calculated airflow based on heat load requirements, whichever is higher.

6 Cooking hood exhaust rate based on exhaust flow rate by cooking equipment categoryReference from 2007 ASHRAE Handbook -HVAC Application (SI); Chapter 31, Table 2

Q = 465 x 1.1 (linear meter of hood) 512 l/s

7 Abbrevations : - AC - AIR-CONDITIONED ACH- AIR CHANGE PER HOURMV - MECHANICAL VENTILATION OA- OUTDOOR AIR

8 Formula for calculating flowrate based on nos. of Air Changes per Hour:Flowrate (L/s) = Room Volume (m3) * ACH / 3.6

9 The breathing zone outdoor airflow shall be determined in accordance with Equation 6-1; ASHRAE Standard 62.1-2007
