INTRODUCTION

The ADNOC Ruwais LNG Project is a two train, near net-zero electrically driven LNG facility, targeting international markets. The feed gas for the project is supplied from the Habshan Gas Processing Plant via a new export gas pipeline. The plant will have two 4.8 MTPA (nominal capacity) electric driven LNG Trains with associated LNG storage/marine export facilities and utilities.

Figure 1 – Project Context

The ADNOC Ruwais LNG Project foresees the following main components at the facility:

• Onshore LNG Liquefaction facilities for 2 x 4.8 MTPA electrically driven LNG Trains (9.6MTPA

total)

• Common facilities including inlet receiving facilities, LNG storage, BOG handling, flare,

refrigerant storage and support buildings.

• Utilities to support the facilities including import power from the national grid.

• Marine facilities for LNG export and bunkering.

1.1

Scope of the Document

This document aims to establish a unified tagging system for the Ruwais LNG plant including jetty.
