Introduction:
Purpose of the Report
This comprehensive report delves into the simultaneous failure of two York chiller evaporators (YORK YCAL0046 1) at Muscat Bay's Staff Accommodation Building 1 on May 18, 2023. The objective is to conduct a detailed examination of the events, scrutinize the roles and responsibilities of involved entities, and assess the incident's impact. While focusing on technical analysis, the report also serves as a basis for exploring the financial and operational consequences of the incident.
Introducing the Involved Companies
- Genetcoo: As the chiller system's Annual Maintenance Contract (AMC) service provider, Genetcoo was responsible for routine maintenance. Remarkably, their last service, indicating no issues, was just ten days before the failure.
- ATPC: Responsible for the AMC of the Building Management System (BMS), ATPC concluded a major service a mere ten days prior to the malfunction, with assurances of proper system functionality.
- COMO: Overseeing the facility management, COMO's role extended beyond general operations to coordinating with subcontractors like Genetcoo and ATPC. Their involvement, although not directly in maintenance, was crucial in monitoring and reporting system status.
