Benefits
Why Work & Rest Hours?
Key advantages of using Work & Rest Hours as part of the Navatom integrated ship management platform.
Automatic STCW, ILO & OCIMF Compliance Monitoring
Four regulatory regimes with five violation types each ensure your fleet meets the exact standard required by flag state, charterer, or company policy. Real-time validation eliminates end-of-month surprises and manual compliance calculations.
Five Violation Types Detected in Real Time
Minimum continuous rest, minimum total rest (24h and 7d), maximum work hours, and rest division violations are flagged the moment they occur — not days or weeks later. Immediate visibility lets officers correct schedules before they become inspection findings.
Template-Based Scheduling Eliminates Repetitive Data Entry
Color-coded operation templates with reusable patterns turn 48-cell daily data entry into a single-click operation. Standard watch rotations, port schedules, and anchor watches are applied instantly, freeing officers to focus on exceptions rather than routine recording.
Non-Conformity Reports for Port State Control Readiness
Generate formal, structured non-conformity reports for any detected violation with one action. Consistent report formatting across your fleet ensures every vessel presents the same professional, inspection-ready documentation to Port State Control officers.
Scales from Single Vessel to Global Fleet
Server-side data handling, secure company data isolation, and office-ship synchronization mean the system performs identically whether you manage one vessel or five hundred. Grow your fleet without outgrowing your compliance platform.
Navatom Work & Rest Hours is the fleet-wide crew compliance platform — enabling ship managers to record, validate, and report seafarer work and rest periods against STCW 2010, ILO Maritime Labour Convention, OCIMF, and custom regulatory frameworks. It replaces paper logbooks, manual calculations, and disconnected spreadsheets with a structured, real-time compliance engine that detects violations the moment they occur and keeps your fleet Port State Control-ready at all times.
Built around a half-hour granularity time grid with 48 cells per crew member per day, the module captures every work and rest period in precise 30-minute increments. Four regulatory compliance regimes (STCW 2010, ILO, OCIMF, and Custom) with configurable thresholds ensure your fleet meets the exact standard required by flag state, charterer, or company policy. Five non-compliance violation types — minimum continuous rest in 24 hours, minimum total rest in 24 hours, minimum total rest in 7 days, maximum total work in 24 hours, and rest division in 24 hours — are validated in real time for every crew member, every day.
Three ship operational modes (Sea, Port, Anchorage) reflect the reality that crew schedules change with vessel status. Color-coded operation templates with reusable patterns eliminate repetitive data entry for routine watches and port rotations. Watchkeeper role tracking, non-conformity report generation, crew remarks, and OPA Clause and Manila Exception support complete a comprehensive hours-of-rest management system that scales from a single vessel to a global fleet.
Capabilities
Key Features
Discover how Navatom Work & Rest Hours helps ship managers work faster and stay compliant with powerful, easy-to-use tools.
Four Regulatory Compliance Regimes
Configure your fleet's work and rest hour rules under four distinct regulatory frameworks: STCW 2010, ILO Maritime Labour Convention, OCIMF tanker vetting standards, and a fully customizable regime for company-specific or flag-state-specific requirements. Each regime defines its own thresholds for minimum rest, maximum work, and rest period division rules.
Switch between regimes at the vessel level or apply a single standard fleet-wide. The Custom regime lets you define bespoke thresholds that go beyond or between the standard frameworks — useful for companies operating under stricter charterer requirements or national regulations that differ from international conventions.
Three Ship Operational Modes
Track crew schedules under three distinct operational modes — Sea, Port, and Anchorage — reflecting the reality that work patterns change fundamentally with vessel status. Each mode carries its own scheduling context, allowing the system to apply mode-appropriate validation rules and display mode-specific schedule templates.
Operational mode transitions are recorded with timestamps, creating a clear log of when the vessel changed status. This mode-aware tracking ensures that compliance calculations account for the different demands of ocean passage, cargo operations in port, and anchor watch duties.
- Sea, Port & Anchorage modes
- Mode-specific schedule validation
- Timestamped mode transitions
- Context-aware compliance checks
Five Non-Compliance Violation Types
The compliance engine monitors five specific violation types in real time for every crew member: minimum continuous rest hours in a 24-hour period (STCW requires at least 6 hours), minimum total rest hours in 24 hours (at least 10 hours), minimum total rest hours in a 7-day rolling period (at least 77 hours), maximum total work hours in 24 hours, and rest division rules within a 24-hour period.
Each violation type is independently configurable per regulatory regime. When a crew member's recorded hours breach any threshold, the system immediately flags the non-compliance with the specific violation type, the crew member's name, the date, and the exact values that triggered the alert. No more end-of-month surprises — violations surface the moment they occur.
- Min continuous rest in 24h (6h STCW)
- Min total rest in 24h (10h)
- Min total rest in 7 days (77h)
- Max total work hours in 24h
- Rest division rule monitoring
Half-Hour Granularity Logging
Record work and rest periods in precise 30-minute increments using a 48-cell time grid for each crew member per day. Each cell represents a half-hour block from 0000 to 2330, with work and rest states clearly distinguished. The "0730" format ensures consistency with IMO standard record-keeping conventions.
The half-hour grid provides the resolution needed for accurate compliance calculation without the overhead of minute-by-minute tracking. Bulk fill operations let you paint work or rest across multiple cells in a single action, while individual cell editing handles exceptions and corrections.
- 48 cells per crew member per day
- 30-minute increment precision
- IMO standard 0730 format
- Bulk fill & individual cell editing
Work/Rest Pattern Templates
Create named schedule templates that define standard work and rest patterns for common watch rotations and duty schedules. Templates are defined per ship and can be reused across days, weeks, and crew members — eliminating the need to manually fill 48 cells for every person every day.
Templates support Active and Inactive status management, so you can maintain a library of patterns for different operational scenarios without cluttering the active template list. Apply a template to a crew member's day with a single action, then adjust individual cells as needed for deviations from the standard pattern.
- Named reusable schedule patterns
- Per-ship template assignment
- Active/Inactive status management
- One-click template application
- Exception handling for deviations
Operations Management
Track special work operations — port calls, emergency responses, cargo operations, bunkering, and other non-routine activities — as distinct operation blocks with their own time boundaries. Operations provide context for why crew members were working outside normal patterns, giving inspectors and auditors the full picture.
Each operation records its type, start and end times, and the crew members involved. Operations integrate with the daily time grid, overlaying special work blocks on the standard schedule. This separation ensures that routine watch hours and exceptional work periods are tracked independently for accurate compliance reporting.
- Special work operation tracking
- Port call & emergency logging
- Time-bounded operation blocks
- Crew member assignment per operation
- Overlay on daily time grid
Color-Coded Operation Templates
Assign distinct colors from a predefined palette to operation templates for instant visual identification on the time grid. Color coding lets crew and managers identify operation types at a glance — blue for sea watches, gold for cargo operations, coral for emergency drills, teal for maintenance periods.
The same-work-color option ensures that identical operation types always display consistently across crew members and days. Templates carry Active or Inactive status, keeping your color-coded library organized. The visual system transforms the daily time grid from a monochrome spreadsheet into an intuitive, scannable schedule.
- Predefined color palette assignment
- Same-work-color consistency option
- Active/Inactive template lifecycle
- Instant visual type identification
Daily & Monthly Log Views
View crew work and rest records in three complementary formats: a multi-crew daily view showing all crew members' 48-cell grids for a single day, a single-crew daily view for detailed individual analysis, and a single-crew monthly view providing the full calendar picture required by STCW record-keeping regulations.
The multi-crew daily view is the primary operational tool — the officer responsible for hours-of-rest records can see the entire crew's schedule at once, spot gaps, and identify potential violations before they occur. The monthly view aggregates daily data into the format needed for regulatory submissions and Port State Control inspections.
- Multi-crew daily overview grid
- Single-crew daily detail view
- Single-crew monthly calendar view
- STCW-compliant record format
- Pre-violation gap identification
Watchkeeper Role Tracking
Designate crew members as watchkeepers on a per-month basis, tracking which personnel are assigned to bridge watch duties. Watchkeeper designation is critical for compliance because STCW applies additional rest requirements to crew members responsible for navigational or engineering watches.
The monthly watchkeeper roster integrates with the daily time grid and compliance engine. When a crew member is designated as a watchkeeper, the system applies the appropriate rest requirements for watch-standing personnel. Changes to watchkeeper assignments are logged for audit trail purposes.
- Per-month watchkeeper designation
- Bridge watch crew identification
- Additional STCW rest requirements
- Assignment change audit logging
Non-Conformity Report Generation
Generate formal non-conformity reports for any detected violation with a single action. Reports are rendered from structured templates and include the crew member's details, the violation type, the specific threshold breached, the actual recorded values, the date and time period, and the applicable regulatory regime.
Non-conformity reports serve as the official record for Port State Control inspections, flag state audits, and internal safety reviews. The structured format ensures consistency across your fleet — every non-conformity report follows the same template regardless of which vessel or officer generates it.
- One-action report generation
- Structured template rendering
- Violation type & threshold details
- Fleet-consistent report formatting
- PSC inspection-ready output
Work Summary Reports
Generate aggregated work summary reports that compile crew hours across configurable date ranges. Summary reports show total work hours, total rest hours, average daily work, and compliance status for each crew member — providing management with a fleet-level view of working time patterns.
Print functionality produces formatted reports suitable for office review, flag state submission, and company record-keeping. Summary reports can be filtered by vessel, date range, department, and rank to answer specific management questions about crew workload distribution.
- Aggregated hours across date ranges
- Per-crew compliance status summary
- Print-ready formatted output
- Filter by vessel, rank & department
Crew Remarks & Annotations
Add per-date, per-crew remarks to document the context behind unusual work patterns, schedule deviations, or operational circumstances. Remarks include a description field that captures the officer's narrative explanation — essential for justifying non-standard hours during inspections.
Remarks become part of the permanent daily record alongside the time grid data. During a Port State Control inspection, the inspector can see not only what hours were worked but why. This contextual layer transforms raw schedule data into a complete, defensible record of crew working time.
- Per-date, per-crew remark fields
- Narrative context for deviations
- Permanent daily record attachment
- Inspection-defensible documentation
OPA Clause & Manila Exception Support
Handle regulatory exceptions with built-in support for the OPA (overriding operational conditions) clause and the Manila Amendments exception provisions. The allowOPAClause and allowManilaException flags can be enabled at the vessel or regime level, modifying how the compliance engine evaluates rest period requirements during qualifying circumstances.
When an OPA clause or Manila exception applies, the system adjusts its violation thresholds accordingly and records the exception in the compliance log. This ensures that legitimate exceptions are properly documented rather than appearing as unexplained violations — critical for demonstrating good-faith compliance during inspections.
- OPA overriding conditions clause
- Manila Amendments exception handling
- Per-vessel or per-regime toggles
- Adjusted violation thresholds
- Exception logging in compliance trail
Dashboard & Analytics
Monitor your fleet's work and rest hour compliance health with dedicated dashboard widgets. Track violation counts, compliance rates, crew workload distribution, and watchkeeper coverage across your entire fleet at a glance.
Widgets provide at-a-glance KPIs for fleet superintendents and DPAs: How many violations occurred this week? Which vessels have the highest non-compliance rates? Are watchkeeper rest requirements being met? Drill down from any widget to the underlying crew data for immediate action.
- Dedicated dashboard widgets
- Fleet-wide violation count tracking
- Compliance rate monitoring
- Watchkeeper coverage overview
- Drill-down to crew-level data
FAQ
Frequently Asked Questions
Common questions about Work & Rest Hours answered.
What regulatory standards does the module support? +
Four regulatory compliance regimes are supported: STCW 2010 (the international standard for seafarer work and rest hours), ILO Maritime Labour Convention, OCIMF (tanker vetting requirements), and a fully customizable regime for company-specific or flag-state-specific rules. Each regime defines its own thresholds for minimum rest periods, maximum work hours, and rest division requirements.
You can switch regimes at the vessel level or apply one standard fleet-wide.
How are work and rest hours recorded? +
Hours are recorded in 30-minute increments using a 48-cell time grid for each crew member per day. Each cell represents a half-hour block from 0000 to 2330.
You can fill cells individually, use bulk fill to paint work or rest across ranges, or apply named schedule templates for standard watch patterns. Three ship operational modes (Sea, Port, Anchorage) provide context for each day's schedule.
What happens when a violation is detected? +
The compliance engine monitors five violation types in real time: minimum continuous rest in 24 hours (STCW minimum 6 hours), minimum total rest in 24 hours (minimum 10 hours), minimum total rest in a 7-day rolling period (minimum 77 hours), maximum total work in 24 hours, and rest division rules. When a threshold is breached, the system immediately flags the specific violation with the crew member's name, date, violation type, and the exact values that triggered the alert.
You can generate a formal non-conformity report for any violation.
Can we create reusable schedule templates? +
Yes. Named operation templates define standard work and rest patterns for common watch rotations and duty schedules.
Templates are assigned per ship, support Active/Inactive status management, and use color coding for visual identification on the time grid. Apply a template to a crew member's day with a single action, then adjust individual cells as needed for deviations.
How does watchkeeper tracking work? +
Crew members are designated as watchkeepers on a per-month basis. When a crew member holds watchkeeper status, the compliance engine applies the additional STCW rest requirements for watch-standing personnel.
The monthly watchkeeper roster integrates with the daily time grid, and changes to watchkeeper assignments are logged for audit trail purposes.
Can we generate compliance reports for inspections? +
Yes. Two report types are available: non-conformity reports for individual violations (generated from structured templates with crew details, violation type, threshold breached, actual values, and applicable regime) and work summary reports that aggregate crew hours across configurable date ranges.
Both report types produce formatted output suitable for Port State Control inspections, flag state audits, and internal safety reviews.
