Arabian Gulf Oil Company (AGOCO) completed the replacement of the main 18-inch valve connecting its Zawiya site to the Zawiya Oil Refining Company on 24 October 2026, restoring a critical link in Libya's downstream supply chain. The operation was carried out on direct instructions from AGOCO management and executed by a joint team drawn from the Pipeline Maintenance Department, the Precision Machinery Department at the Hamada field, and the Valves and Oil Movement Department.
The successful completion of the valve replacement underscores AGOCO's continued investment in maintaining and upgrading ageing pipeline infrastructure across its Libyan operations. An 18-inch trunk valve of this type serves as a primary flow-control point between an upstream gathering or transport system and a refinery intake, meaning any failure or degradation would directly affect crude throughput to the Zawiya refinery. By completing the work through in-house departmental cooperation rather than an externally tendered contract, AGOCO demonstrated that it retains meaningful maintenance capability within its own workforce — though the intensity of the collaborative effort required hints at the complexity of the task.
Zawiya Oil Refining Company is one of Libya's key coastal refining assets, processing crude for domestic fuel supply. Maintaining reliable valve and pipeline integrity on the feeder connection is therefore operationally significant for both AGOCO and the broader Libyan energy system. The article does not specify whether the valve replacement was a planned maintenance item or a response to a detected fault, nor does it detail the wider condition of the connecting pipeline infrastructure.
For Norwegian oil and gas service companies tracking Libya, this event signals that AGOCO is actively maintaining pipeline and valve systems at its operating sites, with Hamada field named as a base for precision machinery support. While this specific task was completed internally, the nature of the work — trunk valve replacement on a major product or crude transfer line — points to a broader infrastructure maintenance cycle that is likely to generate external procurement needs as AGOCO continues to rehabilitate and upgrade assets across its portfolio.
