1 INTRODUCTION

Occidental Oman Gas Company LLC has been awarded the Block 62 development project fromOman Ministry of Oil & Gas (MOG).

The overall development plan for Block 62 includes four (4) discovered fields, i.e., Maradi-Huraymah, Fushaigah, Habiba & Rasafah, in addition to potential development of undiscoveredareas. However, the MOG has informed Oxy of a shortfall of ~220 MMSCFD of gas in the 1stQuarter of 2016. In order to partially alleviate this gas shortfall, Oxy has been tasked by the MOGto develop the Maradi-Huraymah and Fushaigah fields to produce ~150 MMSCFD of gas.

Occidental Oil and Gas Corporation intends to produce up to 50 MMSCFD of gas by August of 2015from Fushaigah field located in block 62 of Oman. This will offset an anticipated 2015 fourth quartergas deficit in Oman of 210 MMSCFD. The field is expected to produce at peak rates for 7 years andrequires the design of well pads, a manifold, a pipeline, a pig launcher, receiver and remote utilities.Gas custody is transferred to the KGP at the end of a 13 km pipeline for gas processing by PDO. Allequipment between Gas wellhead and KGP inlet battery limit is within Detail Design scope. Utilitiesat the downstream of pipeline pig receiver and at multiphase meter skid will be provided by theKGP.

This specification covers the minimum technical requirements for the design, engineering,fabrication, assembly, inspection, testing and supply of Active cool shelter system for Fushaigaharea of Oxy Block 62 project, hereafter referred to as the Client.
