MESSAITFA ABDERRAHIM

In October 2023, I assumed the role of Senior Field Service Engineer at Warri Refining & Petrochemicals Company Limited (WRPC) in Nigeria. This position entailed the meticulous dismantling and disassembly of three Nuovo Pignone Centrifugal Compressors: BCL456, DMCL1008, and 2MCL457. Additionally, I oversaw the dismantling of three Nuovo Pignone Steam Turbines (K801, K1100, K600) used to drive the aforementioned compressors. A critical aspect of my responsibilities involved conducting a thorough inspection and assessment of all dismantled components and equipment, contributing to the preparation of comprehensive spare parts lists crucial for the project's successful execution. As part of my commitment to project transparency, I compiled and prepared the final project report, providing a detailed account of progress and findings. Efficient management and coordination of activities were paramount, particularly in the interim period while awaiting spare parts for the assembly phase, demonstrating my proactive approach to project execution and ensuring seamless operations at WRPC.

In September 2023, I undertook the role of a Field Service Engineer with Baker Hughes at the OPCO SOCIEDADE OPERACIONAL ANGOLA LNG Plant in Soyo, Angola. The primary focus of this assignment was the replacement of the Dry Gas Seal for the High-Pressure centrifugal compressor, specifically C1613/2BCL807. My responsibilities extended beyond mere replacement, encompassing a meticulous Root Cause Analysis and investigation into the underlying problem that led to the Dry Gas Seal failure. This involved a comprehensive examination to identify the genuine cause of the failure, followed by the formulation and presentation of viable solutions. The execution phase involved the actual replacement of the Dry Gas Seal, with subsequent involvement in pre-commissioning, commissioning, and the successful start-up of the facility. This engagement demanded a blend of technical expertise, analytical skills, and hands-on problem-solving to ensure the seamless integration of the new Dry Gas Seal and the optimal performance of the HP centrifugal compressor.

During the period from January to April 2022, I assumed the role of Field Service Engineer (FSE) Lead for Baker Hughes in the context of the QAFCO-6 shutdown in Qatar. This pivotal position involved spearheading crucial tasks during the outage, primarily focusing on a major overhaul for the Nuovo Pignone Compressor 2BCL609 and conducting a minor inspection for BCL453. The scope of responsibilities encompassed a comprehensive Alignment Check and the replacement of Dry Gas Seals. Throughout the assignment, strict adherence to Baker Hughes' Technical Information Letters (TILs) was maintained to ensure precision and compliance with established standards. Beyond the outage phase, I actively contributed to pre-commissioning and commissioning activities, ultimately culminating in the successful start-up of the QAFCO-6 facility. This period demanded a keen attention to detail, technical expertise, and a collaborative approach to align seamlessly with Baker Hughes' protocols and the overall objectives of the QAFCO-6 project.
