Cable block diagrams, Cable routing layout & Cable schedule for HABSHAN- 0,1 & 2 Facilities of ADNOC - WOOD

Introduction

ADNOC Gas Processing, a subsidiary of ADNOC, is responsible for processing associated gas from onshore oil production and gas wells. Key facilities include the Habshan Gas Complex and Bab Plant, which process associated gas and produce Natural Gas Liquids (NGL). The NGL is transported to Ruwais via pipeline for further fractionation.

ADNOC Gas Processing also manages two sulfur handling terminals in Ruwais. The first terminal processes liquid sulfur brought from both onshore and offshore locations, granulates it, and exports it via a ship loading terminal. The second terminal exports granulated sulfur brought from Habshan Sulfur Granulation Plant by rail wagons

Project Background

Sulfur Handling Terminals Overview

1. Ruwais Sulfur Handling Terminal 1

• This terminal is the old Sulfur granulation plant, which was previously operated by ADNOC Refining (formerly Takreer). It was transferred to ADNOC Gas Processing.
• The facility processes liquid Sulfur brought to the plant by tanker trucks from onshore facilities and by ships from offshore operations.
• The liquid Sulfur is processed and granulated at the terminal, after which it is exported through a ship loading terminal known as Ruwais Sulfur Handling Terminal 1.

2. Ruwais Sulfur Handling Terminal 2

• Granulated Sulfur is brought to Terminal 2 by rail wagons from the Habshan Sulphur Granulation Plant.
• The stored granulated Sulfur is then exported via a shipping terminal, which is referred to as Ruwais Sulphur Handling Terminal 2.

F&G System and Project Need
For the safe operation of these facilities, Fire & Gas (F&G) detectors are installed throughout the complex. However, several detectors have become obsolete, and some areas remain uncovered by the current system. To address these issues, ADNOC initiated a project to validate the coverage of the existing F&G system.

Project Award
The task of validating the F&G system was awarded to M/s Wood, who conducted the validation and identified gaps in the coverage. The necessary updates to documents and drawings were outsourced for certain facilities.

Objective

The objective was to review and validate F&G coverage in the Habshan and Bab package units, identifying any gaps to ensure complete coverage. M/s Wood completed the validation, but corresponding documents needed updating. The facilities requiring updates include IES units 02, 03, 10-20, 301-304, and CR-541.

Work Scope

As part of this project, M/s Wood requested the preparation of Cable Block Diagrams, Routing Layouts, and Cable Schedules for 17 facilities.

Workforce

The project was executed by a Senior Instrument Engineer and two designers. Inputs were provided by M/s Wood, with progress evaluated through online meetings every alternate day. The project, which was awarded during the second wave of the COVID pandemic, was largely completed through remote work.
