Schema highlights

equipment_master.csv — 8-class equipment taxonomy per ISO 14224:

Type	Weight	Design Efficiency
heat_exchanger	18%	86.5%
compressor	16%	80.5%
centrifugal_pump	16%	77.5%
reciprocating_pump	8%	74.5%
steam_turbine	10%	82.0%
gas_turbine	8%	36.0%
electric_motor	14%	93.0%
gearbox	10%	95.0%

heat_exchanger_performance.csv — TEMA RGP-T-2.4 fouling-efficiency physics:

efficiency = 86.6 − fouling_factor × 85 − 0.003 × hours + asset_bias + noise pressure_drop = 14 + fouling × 150 + noise (Kern correlation)

The sample's fouling↔efficiency Pearson correlation is r ≈ −0.19 in the deposition zone — validates TEMA-style fouling physics.

compressor_performance.csv — API 617 surge-margin physics:

efficiency = 79.2 + asset_bias − max(0, 12 − surge_margin) × 0.15 + noise anti_surge_valve_pct = 35 − surge_margin + noise (recycle opens as surge approaches) discharge_pressure = suction × pressure_ratio (math-exact)

pump_operations.csv — API 610 + Hydraulic Institute cavitation physics:

cavitation_index = 1 / NPSH_margin + noise (HI standard formula) efficiency = 76 + asset_bias − cavitation_index × 8 + noise

The sample's NPSH↔cavitation correlation is r ≈ −0.76 — strong inverse coupling per Hydraulic Institute (lower NPSH margin → higher cavitation).

vibration_signals.csv — ISO 10816 vibration severity with bearing- temperature coupling:

vibration_rms = 2.28 + health_factor × 0.95 + asset_offset + load + noise bearing_temp = 162 + health_factor × 22 + noise

The sample mean RMS is 2.52 mm/sec — mid-Zone B per ISO 10816 ("acceptable for long-term operation"). Axial/RMS ratio = 0.62, radial/RMS ratio = 0.88 match ISO 10816 directional vibration distribution exactly.

lubrication_analysis.csv — ASTM D6595 wear metals with contamination coupling:

water_ppm = 85 + contamination × 250 + noise iron_ppm = 22 + contamination × 130 + noise copper_ppm = 7 + contamination × 50 + noise

equipment_labels.csv — FAILURE-COUPLED LABELS (first feature- coupled label SKU in the OIL-019/020/021 sequence):

base_health = N(86, 8) if equipment_id in failures: base_health −= U(12, 28) health = clip(base_health, 35, 99) risk = 'high' if health < 70 else 'medium' if health < 85 else 'low'

The sample observes a 20-point health gap between failed and non-failed equipment (failed mean ~65, non-failed mean ~85) — validates feature- coupled label generation per ISO 14224 + API 580/581 RBI standards.

Suggested use cases

1. Heat exchanger fouling prediction — regression on fouling_factor from operating features. Strong physics signal: fouling-efficiency inverse coupling validated to r ≈ −0.19.
2. Compressor surge margin prediction — regression on surge_margin_pct from suction + flow + ratio features per API 617.
3. Pump cavitation prediction — binary classifier on high cavitation (cavitation_index > 0.3) from NPSH + head features. Very strong physics: NPSH-cavitation r ≈ −0.76.
4. Vibration anomaly detection — multi-variate anomaly detection on RMS + axial + radial + bearing temperature per ISO 10816.
5. Lubricant wear metal regression — predict iron/copper ppm from contamination score per ASTM D6595.
6. Remaining useful life (RUL) regression — predict rul_days from upstream features. Standard PHM/CBM benchmark target.
7. Health score regression — predict health_score from upstream features. Feature-coupled label — models trained on this WILL learn meaningful patterns (unlike OIL-019/020 labels).
8. 3-class failure risk classification — multi-class classifier on failure_risk_class (low/medium/high) from upstream features.
9. Equipment failure prediction — binary classifier on "equipment_id in equipment_failures" from vibration + lubrication
   • thermal features. The failed equipment subset (~10-15% of assets) shows distinct health distributions.
10. Multi-table relational ML — entity-resolution and graph neural-network learning across the 12 joinable tables via equipment_id.

Loading

from datasets import load_dataset
ds = load_dataset("xpertsystems/oil021-sample", data_files="vibration_signals.csv")
print(ds["train"][0])

Or with pandas:

import pandas as pd
eq     = pd.read_csv("hf://datasets/xpertsystems/oil021-sample/equipment_master.csv")
vib    = pd.read_csv("hf://datasets/xpertsystems/oil021-sample/vibration_signals.csv")
lube   = pd.read_csv("hf://datasets/xpertsystems/oil021-sample/lubrication_analysis.csv")
fail   = pd.read_csv("hf://datasets/xpertsystems/oil021-sample/equipment_failures.csv")
labels = pd.read_csv("hf://datasets/xpertsystems/oil021-sample/equipment_labels.csv")

# All 12 tables joinable by equipment_id
joined = eq.merge(labels, on="equipment_id")

# Failed vs non-failed equipment for RUL ML
failed_ids = set(fail["equipment_id"])
labels["failed_flag"] = labels["equipment_id"].isin(failed_ids).astype(int)
# Now you have a clean feature-coupled binary classification target

Reproducibility

All generation is deterministic via the integer seed parameter (driving both random.seed and np.random.seed). A seed sweep across [42, 7, 123, 2024, 99, 1] confirms Grade A+ on every seed in this sample.

Honest disclosure of sample-scale limitations

This is a sample product calibrated for predictive maintenance ML research, not for live operational decisions. Several notes:

1. Detail-table coverage is equipment-type-conditional. Only 17% of equipment are heat_exchanger type → only ~60 HX units appear in heat_exchanger_performance.csv. Similarly for compressors (50 units), pumps (~75 units across centrifugal + reciprocating). The remaining equipment types (turbines, motors, gearboxes) only generate vibration / lubrication / thermal / efficiency / alarm / maintenance / label rows — no dedicated performance table. For turbine-specific or motor-specific ML, the full product v1.1 will add type-specific detail tables.

2. Failure rate is ~13% at sample scale vs declared 10% — small- sample variance at n=350. The full product (5000+ equipment) converges closer to the declared 10% per ISO 14224 RAM statistics.

3. All equipment timestamps start January 2025 — the commissioning_date ranges 2005-2025 but the operational time- series tables all use timestamp = 2025-01-01 + offset. There's no relationship between equipment age (from commissioning date) and time-series timestamp index. For age-conditional analysis, use equipment_master.age_years as a feature rather than inferring from timestamps.

4. Efficiency degradation in efficiency_tracking.csv is mild over the 120-day window — degradation rate ~0.0009/hr × 2880 hr = ~2.6% total decline over 4 months. The runtime↔efficiency correlation is weak (r ≈ −0.05) at sample horizon. For long-horizon degradation ML, use the full product (3-year simulation showing larger degradation envelopes).

5. Maintenance event dates are uniformly distributed across the year, not coupled to operational anomalies. Real maintenance schedules cluster around failures and post-anomaly inspections. Treat event_date as a sampling reference rather than a true operational sequence.

6. Alarm trip rate is ~8.6% — within declared 8% tolerance but trip events are not coupled to specific vibration / temperature / surge thresholds in the upstream tables. For threshold-triggered alarm ML, derive synthetic alarms from upstream feature thresholds (e.g., HI_VIB when vibration_rms > 4.5).

7. Vibration RMS↔bearing temperature correlation is moderate (r ≈ 0.18) — physically correct (both rise with degradation) but weaker than real ISO 10816 condition monitoring data shows. Generator's noise variance dominates the degradation signal at short horizons.

8. Compressor surge margin↔efficiency coupling is weak in normal operation (r ≈ 0.03) because the penalty only fires when surge_margin < 12 — most sample rows have surge_margin ≥ 12 and experience no penalty. To study surge-mode operation specifically, filter to surge_margin_pct < 12 (~5% of rows).

Cross-references to other XpertSystems OIL SKUs

This SKU is the first cross-stream equipment SKU in the catalog — applicable to upstream, midstream, and downstream operations:

SKU	Layer	Equipment focus
OIL-012	Upstream	Rig sensor IoT (drilling equipment)
OIL-014	Upstream	Artificial lift performance (ESP/rod pump/gas lift)
OIL-019	Downstream	Refinery process operations (per-unit)
OIL-021	Cross-stream	Equipment performance: HX/compressor/pump/turbine/motor/gearbox (this SKU)

OIL-021 vs OIL-014: OIL-014 focuses on production artificial-lift equipment (ESP, rod pump, gas lift) with lift-system-specific physics (fillage, fluid pound, gas interference). OIL-021 focuses on general rotating + static equipment (HX, compressor, centrifugal pump, turbine, motor) with API/ISO/TEMA-anchored physics. Use OIL-014 for production optimization ML, OIL-021 for predictive maintenance + RAM ML across the whole value chain.
