Reliability engineering for
AI-era data centers
in Hong Kong.
Lifecycle decisions for uptime, AI-density readiness, liquid-cooling reliability, and audit-ready evidence — on top of the DCIM, BMS and EPMS you already own.
The ReliDC Reliability Method
Technical Hierarchy
ISO 14224 9-level equipment taxonomy sourced from P&IDs and SLDs. Clean asset boundaries for chillers, HV transformers, PDUs, CRAHs and CDUs.
Asset Criticality Rating
6-step facilitated ranking. Safety, Environment, Reputation, Financial. 5x4 matrix. Classes A-D map to strategy, standby, spares and RCA candidates.
FMEA & Asset Strategy
RCM decision logic per SAE JA1011/1012. On-condition, scheduled, failure-finding, RTF or redesign — tuned to MTBF, cost and availability.
Embed in CMMS
Strategies, spares, RCA candidates and KPIs written back into your CMMS. Between audit cycles, the loop keeps improving.
Why now: Hong Kong urgency.
Legacy halls at 5–15 kW/rack meet AI workloads asking for 40 kW+.
Direct-to-chip and rear-door heat exchangers introduce new failure modes.
CLP/HKE capacity is the binding limit. Every stranded kW is lost revenue.
Mandatory 5-year energy audits for Schedule 4 Type 10/11 data centres.
Banks must map dependencies and scenario-test critical facilities.
AI DCI Superhighway means faults now cascade across TKO ↔ Hetao.

All insights →HKMA OR-2: the evidence pack your board needs before May 2026
A pragmatic checklist for banks and their outsourced data-center providers — mapped to severe-but-plausible scenarios, tolerance for disruption, and third-party dependency mapping.
Liquid Cooling Is Table Stakes. Reliability Isn't.
Everyone will have coolant loops. Few will have failure-mode libraries for them.
Commissioning liquid-cooling CDUs without breaking your reliability envelope
Field notes from three AI-density retrofits in Tseung Kwan O and Tsuen Wan — where the failure modes live, and the six telemetry points we now insist on before energisation.
A reliability assessment scoped to one hall.
Fixed scope, fixed fee, HKD 300K–1.2M depending on hall complexity. Baseline asset model, FMEA-ranked risk register, and OR-2 / BEEO evidence starter pack.
