(INCLUDING SPECIFICATIONS)

1. INTRODUCTION

1.1 Purpose

This Scope of Work details the Company’s requirements and standards for the Works to be

performed by the Contractor under the Contract.

1.2 Background

The Lorim Point Fuel Farm is filled with diesel fuel via fuel ships which dock up at the Lorim Point

Export Wharf and transfer the fuel into Tank 11 via a DN200 carbon steel pipeline. A section of

the DN200 pipeline is currently installed underground.

Figure 1 below illustrates the DN200 diesel line pipe route from the Lorim Point Export Wharf to

the Fuel Farm.
