ShiftIntel — Operational Continuity & Multimodal Memory

Overview

ShiftIntel is an evidence-grounded operational continuity and multimodal memory platform engineered for continuous process industries, including oil & gas refining, petrochemicals, offshore production, and power generation. Rather than acting as a simple text summarizer or passive digital logbook, ShiftIntel deterministically reconstructs shift turnovers by computing physical changes from process telemetry, alarm historians, and operator actions into an immutable, cited baseline.

The Problem

Over 40% of catastrophic process safety incidents—such as the Piper Alpha disaster and the BP Texas City explosion—occur during start-up, shutdown, and shift turnover windows, despite these phases representing under 5% of facility operating time. Traditional handovers rely on hurried verbal exchanges and unstructured shift notes that degrade under end-of-shift fatigue. This causes an immediate 15% to 25% "golden hour" Overall Equipment Effectiveness (OEE) drop as incoming crews spend 60 to 90 minutes hunting down equipment statuses, bypassed interlocks, and standing alarm floods.

The Solution

ShiftIntel eliminates handover blind spots by separating deterministic physical facts from narrative generation:

• Code derives physical process realities directly from DCS telemetry, alarm limits, and CMMS work orders.
• AI (Google Gemini) synthesizes structured SBAR (Situation, Background, Assessment, Recommendation) briefings strictly grounded in the pre-computed fact pack.
• Every narrated abnormal assertion must carry an exact citation pointing to a verifiable fact ID; ungrounded assertions are rejected automatically by an epistemic validator.

Key Capabilities

• Deterministic Fact Engine: Audits boundary limit excursions (HIHI/HI/LO/LOLO), API RP 584 Integrity Operating Windows (IOW), chattering and standing alarms per ISA-18.2, control loops left in manual mode, and stale/flatlining instruments.
• ISA-18.2 Alarm Auditor: Flags standing alarms (>1h), unacknowledged shelved alarms exceeding TTL, and bad-actor chattering alarm floods before the crew leaves.
• Grounded SBAR Narrative: Classifies statements into [FACT], [OBSERVATION], [HYPOTHESIS], and [ACTION] with inline citation chips jumping directly to raw telemetry timestamps and values.
• Cryptographic Dual Sign-Off: Outgoing and incoming supervisors independently verify conditions with typed unit-name confirmation and explicit acknowledgment of open anomalies.
• Tamper-Evident SHA-256 Audit Ledger: Cryptographically chains handover events (seq → prev_hash → payload_hash → entry_hash) into an append-only audit trail verifiable in one click.
• Cross-Shift Continuity & Hybrid Search: Carried-forward action tracker, multi-shift return briefing synthesis, and full-text search across historical logs and fact packs.

Anti-Surveillance & Work-Council Alignment

Engineered strictly under European labor and works-council standards (BetrVG §87):

• Zero worker-productivity tracking, keystroke monitoring, or response-time scoring.
• Shift handovers attribute operational actions strictly by role and console desk (e.g., "Board Operator · Desk 2"). Personal identities exist solely in access-control ledgers.
• Grayscale-first ISA-101 high-performance HMI reserving color solely for abnormal process deviations.

Who It's For

• Board/Console Operators: Instant delta awareness of manual overrides, bypassed interlocks, and alarm floods without unfair blame.
• Field Operators: Structured logging of walkdown symptoms, actions, and equipment defects linked directly to plant assets.
• Shift Supervisors: Automated, audit-ready turnover packages with dual sign-off enforcement.
• Process & Reliability Engineers: Cross-shift diagnostic timelines aligning telemetry trends, alarms, and work orders in a single view.
• Plant Operations Leadership: Elimination of golden-hour orientation lag, regulatory compliance readiness, and zero-loss operational continuity.
