What AVENCA does

AVENCA Limited is a UK-based specialist data analytics firm, founded in 2001 and headquartered in Alderbury near Salisbury (Wiltshire), that extracts operational, safety, and investigative insights from black-box recorder data across three sectors: marine Voyage Data Recorders (VDR), railway On-Train Monitoring Recorders (OTMR), and Health and Usage Monitoring Systems (HUMS) on aircraft and land vehicles. It serves shipping companies, P&I Clubs and insurers, flag state authorities, national accident investigators (with active co-development relationships with UK MAIB and NTSB), enforcement authorities, marine consultancies, UK Train Operating Companies working with Network Rail, and aerospace/military customers globally. The company is privately held, ISO 9001 certified (Alcumus ISOQAR, Cert No. 9793), operates from a single UK site with 1-10 employees, and reports worldwide reach while disclosing no financial, funding, or ownership data.

The company's product portfolio is built around proprietary software that fuses multiple recorder data sources (VDR, AIS, ECDIS, VTS, GPS, OTMR, HUMS, CCTV and audio) into unified analysis environments. Marine offerings include AURA (web-based remote analysis delivered as a service, with UKHO AVCS Online chart integration), MADAS (desktop accident-investigation suite co-developed with UK MAIB and NTSB), MADCAP (field witness-data capture), VDCS (extended VDR capture with at least 90-day retention), and VOQA (claimed as the world's first comprehensive maritime operations Quality Assurance system, providing 24/7 proactive monitoring of VDR data). Railway offerings include TDSE for automated delay attribution with root-cause diagnosis, plus VOQA:Alert! and dedicated tools for compliance, Sectional Running Times, speed limit checking, wheel slip/slide, and driver standards monitoring. HUMS offerings include AIDE for pattern recognition and anomaly detection, model-based diagnostics/prognostics for fault detection with reduced false alarms, and the COEIA cost-benefit framework. All solutions leverage existing sensor and recorder infrastructure without requiring additional onboard hardware, and several include Digital Signal Processing for audio extraction and enhancement.

AVENCA pursues a sales-led, direct engagement go-to-market targeting enterprise and government customers. Revenue streams comprise one-time software licenses and turnkey analysis-laboratory deployments (laptop, transportable, or full laboratory formats), bespoke professional services (incident replay, data recovery, audio enhancement, animated reconstructions), recurring routine/long-term monitoring subscriptions via VOQA, and fixed-price Remote Navigation Audits delivered by qualified Master Mariners. Pricing is predominantly quote-based, with fixed-cost disclosure limited to the RNA service. The firm has secured no disclosed external funding and has no recorded M&A, leadership change, or public listing activity across its history.

Products and services

• AURA (Avenca User Remote Analysis) Web-based data analysis service enabling replay and analysis of marine digital data (VDR, AIS, CCTV, radar/ECDIS, audio) over the web using a standard browser, providing animated incident reconstructions with synchronized nautical charts, radar images, gauges, and audio. Sold to maritime operators, investigators, insurers and law firms without requiring software installation.
• MADAS (Marine Accident Data Analysis Suite) Marine accident investigation software enabling investigators to fuse digital data from VDR, AIS, ECDIS, VTS, GPS, CCTV and audio sources in a common toolset for synchronized replay, display of ship positions on nautical charts, radar overlay, audio synchronization, and multi-parameter graphing.
• MADCAP (Marine Accident Data CAPture) Field data capture software enabling investigators to digitally gather witness statements with estimated ship positions, audio recordings, videos, and photos linked to specific locations and times on charts, with data exportable to MADAS for integrated laboratory analysis.
• VOQA (Voyage Operations Quality Assurance) — Marine Proactive safety management software that automatically identifies trends and events in routine ship VDR data which can lead to reduced safety margins or increased operating costs, enabling 24/7 automated monitoring, reporting, and risk mitigation.
• VDCS (Voyage Data Capture System) Hardware/software system interfacing with VDRs to provide extended recording facilities and automatic backup storage of typically at least 90 days of VDR data, ensuring data is always available following incidents and enabling proactive safety management when combined with VOQA.
• TDSE (Time Delay Search Engine) Railway delay attribution software that automatically determines the impact of each delay event in min:sec, identifies exact location and time, and diagnoses the underlying root cause to enable resolution of systemic problems. Works with any OTMR.
• VOQA:Alert! / Compliance Monitoring User-configurable railway compliance monitoring tool that automatically searches through OTMR files to confirm driver compliance with company standards, detecting undesirable driving styles and ensuring defensive driving practices.
• SRT Check Railway software that automatically analyses OTMR data against timing points to produce Sectional Timing Reports, identifying services consistently failing to meet Section Running Times to inform timetable revisions.
• Speed Check Railway software that links OTMR measurements with speed limit data to identify track sections where trains consistently exceed limits or never approach them, revealing unrecorded events and maintenance optimization opportunities.
• Track Slip & Slide (Trackslip) Railway software that automatically identifies where and when wheel slip or slide events occur, showing their impact on braking performance and enabling drivers to be briefed on affected locations and focused track maintenance.
• Driver Standards Monitoring Railway software using VOQA technology to automatically detect driver behaviors affecting safety and performance including early braking, power settings, station dwell times, and route adherence.
• AIDE Software Software using automated learning and pattern recognition techniques to automatically detect abnormal patterns in HUMS or Condition Monitoring data that conventional threshold-based systems would miss, protecting against unexpected faults.
• Remote Navigation Audits (RNA) Fixed-price service in which trained Master Mariners comprehensively review ship VDR data against regulations, best practice, and company procedures, producing reports with observations, recommendations, screenshots, and video clips for fleet-wide debriefing and training.
• Analysis and Playback Facilities Turnkey VDR replay and analysis systems delivered in laptop-based, transportable, or complete laboratory configurations for national investigation authorities and shipping companies, including hardware, software, training, and ongoing support.
• Incident Replay and Analysis Services Specialist services including data recovery from damaged storage media, audio extraction and enhancement using Digital Signal Processing, and animated reconstructions for investigation, litigation, and training purposes.
• COEIA (Combined Operational Effectiveness and Investment Appraisal) HUMS design and evaluation service using a model that predicts realizable benefits, estimates implementation costs, and identifies required changes through 'what-if' scenario analysis to help customers optimize their Health and Usage Monitoring System investments.
• Model-Based Diagnostics/Prognostics Model-based diagnostic service processing monitoring signals using knowledge-based models of fault behavior to detect divergence between measured and predicted values, enabling increased sensitivity to fault onset without increased false alarm rates.

Quantifiable outcome

• VDCS retains at least the last 90 days of VDR data automatically, preventing data loss from the standard 12-hour VDR overwrite cycle.
