V4RDE Methodology

From Maritime Data to Intelligence, Decision Support and Investigation

V4RDE can be used as a maritime awareness dashboard, as an AJP-aligned intelligence and decision support platform, or as an investigative framework for case building and evidence preparation.

The difference is not the data displayed. The difference is the method applied to the data.

Most maritime platforms stop at visibility. V4RDE is designed to support the full intelligence process: defining the question, collecting relevant signals, processing and grading observations, and disseminating decision-ready outputs.

Modes of Use

One platform. Three levels of use.

V4RDE can be used at different levels depending on the user, mission and required evidentiary standard. Some users need situational awareness. Others need intelligence assessments for decision support. Some need to investigate, document and defend a finding.

Mode 1

Dashboard

Observe maritime activity and risk indicators

Operations · Security · Maritime industry

Map view, alerts, vessel profiles, area monitoring

Mode 2

Intelligence & Decision Support

Answer intelligence requirements and support decisions

Defence · Government · Intelligence · Critical infrastructure

Briefings, assessed risk, priority indicators, recommended action

Mode 3

Investigation & Case Building

Examine, document and defend maritime activity

Investigators · Compliance · Legal · Regulators

Timelines, evidence bundles, source records, confidence grading

Mode 1

Maritime Awareness Dashboard

At the simplest level, V4RDE provides maritime situational awareness. The dashboard allows users to observe vessels, areas, alerts and risk indicators without running a full intelligence workflow.

What the user sees

  • Vessel movements and AIS activity
  • Areas of interest
  • Sanctions exposure
  • Dark activity indicators
  • Basic anomaly alerts
  • Port and infrastructure proximity
  • Vessel profiles

When this mode is sufficient

  • Monitoring known areas of interest
  • Maintaining a maritime operating picture
  • Following vessels or fleets
  • Screening for visible risk indicators
  • Supporting daily operational awareness

Dashboard use shows what is visible. It does not, by itself, create intelligence. Intelligence begins when observations are tied to a question, assessed against alternative explanations, graded and disseminated to support a decision.

Mode 2

Intelligence and Decision Support

This is the primary V4RDE methodology. In this mode, the user starts with an intelligence requirement, not with a map. The purpose is to answer a decision-relevant question.

Example intelligence requirements

  • Which vessels of interest are operating near critical infrastructure?
  • Are sanctioned or shadow fleet vessels increasing activity in this area?
  • Which vessels show behaviour consistent with deceptive shipping practices?
  • Is a specific maritime pattern changing over time?
  • What should be escalated to leadership?
  • What is the assessed confidence behind this finding?

V4RDE structures this workflow around the intelligence cycle. The system is designed to help analysts move from raw maritime signals to assessed findings, graded confidence and decision-ready reporting.

AJP-Aligned Intelligence Workflow

Four functions. One intelligence cycle.

V4RDE operationalises the intelligence cycle through four functions aligned to AJP-2.0: Direction, Collection, Processing and Dissemination. These functions turn maritime data into decision support.

Function
V4RDE implementation
User question
Direction
Define the intelligence requirement, decision need, area of interest, vessel class or investigative question
What do we need to know, and why?
Collection
Configure AIS, satellite evidence, sanctions data, GNSS context, watchlists, registries and OSINT against the requirement
What sources are relevant?
Processing
Correlate observations, reconcile identity, detect anomalies, test hypotheses and grade credibility
What does the evidence indicate?
Dissemination
Deliver alerts, reports, evidence bundles, briefings or API outputs to the right user
Who needs to act on this?
Direction

Start with the intelligence requirement

V4RDE is most powerful when the workflow begins with a clearly defined intelligence requirement. The requirement defines what the system should look for, what sources should be prioritised and what type of output is needed.

Requirement type
Example
Area based
Monitor vessels of interest near a port, terminal, offshore asset or subsea infrastructure
Vessel based
Assess whether a vessel shows indicators of deceptive shipping practice
Network based
Identify relationships between vessels, ownership structures and sanctions exposure
Event based
Reconstruct a dark activity event or suspicious maritime incident
Trend based
Assess whether shadow fleet activity is increasing in a defined region

Without direction, the system produces observations. With direction, it produces intelligence.

Collection

Bring relevant maritime signals together

V4RDE collects and organises relevant signals against the defined requirement. Collection may include cooperative reporting, non-cooperative observation, sanctions records, GNSS integrity context, registries, watchlists and OSINT.

Source class
Role
AIS and cooperative reporting
Shows what the vessel claims
SAR and optical observation
Shows what can be independently observed
GNSS integrity context
Assesses whether reported positions can be trusted
Sanctions and threat lists
Identifies named or linked entities
Registries and ownership data
Supports identity and network understanding
OSINT and analyst records
Adds context and corroboration
Processing

Correlate, reconcile and assess

Processing is where V4RDE moves beyond display. The system correlates observations in time and space, reconciles vessel identity, detects anomalies, grades sources and prepares assessed outputs for analyst review.

Time-windowed correlation
Geospatial joins
AIS gap detection
SAR correlation
Identity reconciliation
MMSI, IMO, name and call sign handling
Ghost twin detection
Sanctions matching
GNSS credibility downgrading
Admiralty Code grading
Hypothesis testing
Analyst review

Processing is what separates intelligence from visualisation.

Dissemination

Deliver decision-ready outputs

V4RDE outputs are routed according to user need, sensitivity and purpose. Some users need alerts. Some need executive briefings. Some need audit-ready evidence bundles. Some need API outputs into existing systems.

Output
Intended user
Alert
Operations, security teams, analysts
Intelligence brief
Leadership, government, defence, crisis teams
Vessel of Interest report
Compliance, maritime industry, investigators
Evidence bundle
Legal, regulators, enforcement, audit
API output
Platforms, data teams, partner systems
Trend assessment
Strategy, policy, risk and investment teams
Mode 3

Investigation and Case Building

Investigation mode is used when a maritime event must be examined, documented and defended. This mode is relevant for compliance, legal review, enforcement support, insurance, incident review, sanctions exposure and internal investigations.

Investigation workflow

Step
Purpose
Define case
Establish question, scope, time period, vessels and area
Preserve source records
Capture relevant observations and source references
Build timeline
Reconstruct movement, gaps, anomalies and related events
Reconcile identity
Assess vessel identity, aliases, ownership and registry changes
Assess evidence
Grade source reliability and information credibility
Review hypotheses
Consider alternative explanations
Package findings
Produce evidence bundle, report or briefing

Case outputs

  • Case identifier
  • Timeline
  • Vessel identity graph
  • AIS gaps
  • Sanctions links
  • SAR correlation
  • GNSS integrity context
  • Source records
  • SHA-256 content hashes
  • Admiralty grading per finding
  • Analyst sign-off
  • TLP marking
  • Chain of custody

Investigation mode is built for explainability. The product must show not only what V4RDE concluded, but how the conclusion was reached.

Collection and Fusion Architecture

The five fusion layers

The five fusion layers are the collection and fusion architecture beneath the AJP-aligned workflow. Each layer answers a different question. No single layer is sufficient on its own.

Layer
Question answered
Function
Cooperative reporting
What does the vessel claim?
AIS, LRIT, port call reporting
Non-cooperative observation
What can be seen regardless of what is claimed?
SAR, optical imagery, independent observation
Signal integrity context
Can the reported position be trusted?
GNSS jamming and spoofing context
Authoritative threat lists
Who is already named, and by whom?
Sanctions, port state control, watchlists
Structured knowledge
Who is the vessel, and what has it done?
Registries, ownership, history, aliases, voyage patterns
Source Grading

Every output is graded

V4RDE does not present every finding as equally certain. Each finding carries a grade for source reliability and information credibility, allowing users to distinguish confirmed information from plausible, uncertain or unverified information.

Grade
Meaning
Maritime example
A1
Reliable source, confirmed by other sources
AIS from official source corroborated by SAR at the same time and place
B2
Usually reliable source, probably true
Registry and sanctions match, limited independent corroboration
C3
Fairly reliable source, possibly true
Commercial AIS pattern consistent with prior behaviour
F6
Cannot be judged
Uncorroborated claim from anonymous or weak source

Confidence is not decoration. It is part of the product.

Human Review

Analyst accountable by design

V4RDE produces graded candidates. An analyst confirms, downgrades or rejects findings before high-impact dissemination. The system is designed to support analytical judgement, not replace it.

Human review triggers

Identity revival
Ghost twin candidates
High-impact dark activity
Sanctions-linked vessels
Critical infrastructure proximity
Low confidence, high consequence findings
Conflicting source records

The analyst remains accountable. The platform preserves the reasoning.

Evidence Bundle

Every serious finding must be defensible

When a finding may influence operational, legal, regulatory or commercial decisions, it must be explainable and auditable. V4RDE evidence bundles are designed to preserve the basis for the assessment.

Case identifier
Generation timestamp in UTC
Analyst identity and sign-off
TLP marking
Enumerated source records
SHA-256 content hashes
Admiralty Code grading
Source scene identifiers (SAR)
Detector settings where relevant
Identity graph snapshot
Analytical notes
Chain of custody

The evidence bundle is not an export format. It is the accountability layer.

From visibility to intelligence

V4RDE can be used as a dashboard. Its full value is realised when maritime data is handled through a structured intelligence process.

That process starts with a requirement, collects relevant signals, processes and grades the evidence, and disseminates outputs that decision makers, analysts and investigators can act on.
