Benefits

Why Circulars?

Key advantages of Circulars as part of Navatom's integrated platform.

Every Circular Reaches the Right Crew at the Right Time

Ship and rank-based distribution controls, mandatory read tracking, and fleet-wide completion monitoring ensure that every circular is received, read, and acknowledged by exactly the personnel who need it — with verifiable proof for every communication.

Circular Control Ready for ISM Audits from Day One

A seven-stage lifecycle, approvers named per category, version-controlled documents with a marked-up comparison for every revision, and a complete event history deliver the controlled communication discipline that the ISM Code, classification societies and port State inspectors expect, without manual record-keeping.

Version-Controlled Notices with Full Diff History

Every revision is compared with the version before, marking exactly what changed. The complete version chain from first draft to current release is preserved permanently, providing the documentary evidence that regulatory auditors require.

Verified Crew Acknowledgement Across Your Fleet

Mandatory read tracking with per-rank completion monitoring and acknowledgement records confirms that every required person on every assigned vessel has read every required circular. Dashboard widgets show completion status at a glance.

Scales from Single Vessel to Global Fleet

Server-side pagination, advanced filtering, and multi-tenant architecture mean the system performs identically whether you manage one vessel or five hundred. Grow your fleet without outgrowing your circular management platform.

Overview

Circulars writes company notices, runs them through approval, numbers them by year and version, sends them to chosen ships and ranks, and confirms who has read each one.

Read the full overview of Circulars

Navatom Circulars is the fleet-wide circular distribution and compliance system for maritime operations — handling company notices, regulatory updates, operational directives, and third-party circulars with full version control, multi-stage approval workflows, and verified crew acknowledgement. It replaces email chains, untracked PDF attachments, and paper-based distribution logs with a structured, auditable digital pipeline that ensures every circular reaches the right crew at the right time.

Built around two circular types (Document and PDF), a seven-stage definition lifecycle, and a formal approval workflow with send-to-approval, approve, reject, release, and re-release actions, the module delivers the controlled communication discipline that ISM Code and classification societies demand. A built-in document editor lets authors create and revise Word-based circulars directly in the browser, while PDF circulars can be uploaded and distributed as-is.

Ship and rank-based distribution controls ensure each vessel and each crew position receives only the circulars relevant to them. Mandatory read tracking with per-rank completion monitoring and acknowledgement records confirms that every required person has read every required circular.

Four dashboard widgets (total circulars, released this year, awaiting approval, and approved but not yet published), with read shares per ship and reminders for crew who have not read, transform circular management from an administrative checkbox into a measurable fleet intelligence tool.

Capabilities

Key Features

How Circulars helps ship managers work faster and stay compliant.

01

Mandatory Read Tracking

Mark circulars as read-required and track reading across your entire fleet. Crew in the assigned ranks confirm each version by typing "read and understood", and the system records who read it and when, providing verifiable proof of communication.

Each ship's row shows the share of its crew who have read the circular, and expands to every crew member, whether they have read it and by when. On board, the Captain sees the read status of the whole ship. Shore management can see at a glance which vessels need follow-up.

Set the days the crew have to read it. Crew who have not read it get a reminder when it falls due and another when it is overdue.

CIR

Mandatory Read Tracking

  • Read-required circulars confirmed with "read and understood"
  • Read share per ship, down to each crew member
  • Days to read, with reminders when due and overdue
  • The Captain's view of the whole ship
  • Confirmed again for every new version

02

Ship & Rank-Based Distribution

Control exactly which vessels and which crew positions receive each circular. Assign it to ships or to ship groups, including ships that join the group later, then choose which of 51 onboard ranks must read it, from master and chief engineer to junior officers and ratings. Crew in those ranks get a newsfeed item on the ship app.

Distribution assignments ensure that operational directives reach only the vessels they apply to, and that within each vessel, only the relevant crew positions are notified. A tanker-specific safety circular won't appear on your bulk carriers, and an engine-room directive won't burden deck officers.

CIR

Ship & Rank-Based Distribution

  • Assign to ships or ship groups
  • Choose from 51 onboard ranks
  • Vessel-specific circulars won't appear on unassigned ships
  • Assignments can change after release and stay through revisions

03

Version History & Document Diffing

Every circular maintains a complete version history with numbered revisions, release timestamps, and author attribution. When a circular is revised, Navatom compares the new version with the one before, showing exactly what changed.

Each version's change log opens a marked-up comparison, with insertions and deletions highlighted, ready to read on screen or to print.

The published version stays in force until the revision is approved and published. The full version chain is preserved permanently for compliance auditing.

CIR

Version History & Document Diffing

  • Complete version chain from first draft to current release
  • A marked-up comparison for every revision
  • Insertions and deletions highlighted
  • The published version stays in force until the revision is published
  • All diffs preserved permanently for compliance auditing

04

Multi-Stage Approval Workflow

  • Send a draft for approval with a remark
  • Approve or Reject with recorded reviewer identity and comments
  • Approvers named per category
  • Publish, revise and publish again
  • Full audit trail of every approval and rejection decision
How it works

Circulars move through a structured approval pipeline: authors create and edit drafts, then send them for approval with a remark for the approver. Designated reviewers evaluate the content and either approve it for release or reject it with feedback.

Approved circulars are released to the fleet; rejected circulars return to the author for revision.

Each category names the group whose members approve its drafts, and any one of them approves. Publishing, and publishing a revision, control when approved content reaches vessels.

Every approval and rejection is recorded with the reviewer's identity, timestamp, and decision, providing a complete audit trail for regulatory compliance.

05

Categories, Priority & Valid-Until Dates

  • Categories with their own posting and approving groups
  • Read requirement and days to read set per category
  • Priority on every circular
  • Deprecated automatically after its valid-until date
  • Circulars expiring soon listed
How it works

Sort circulars into categories, such as flag State, class or company notices, each with its own color, the user group that may post to it and the group whose members approve its drafts. A category also sets whether its circulars must be read, and in how many days.

Give each circular a priority and a valid-until date. A circular is deprecated automatically after its last day in force, and the circulars expiring soon are listed, so nothing out of date stays in front of the crew.

06

Ask Your Circulars with Navatom AI

  • Answers from your circulars and manuals, with sources
  • Who has not read a circular, per vessel and rank
  • Circulars expiring soon and drafts awaiting approval
  • Each crew member's unread circulars on board
  • Every draft waits for your confirmation
How it works

Ask Navatom AI what your circulars say, and it answers from your own circulars and manuals, naming the document each answer comes from. It answers only from the documents you are allowed to read.

It also drafts a new circular, shows who on a vessel has not read one, lists the circulars expiring soon and the drafts waiting for approval, and sends a draft for approval or releases it once you confirm. On board, it tells each crew member which circulars they still have to read.

07

Lessons-Learned Circulars from Issues

  • Lessons-learned circulars drafted from issues
  • No names of the people involved
  • Issues shared in, referring to or raised from a circular
  • Navatom AI raises an audit finding for crew who have not read a circular
How it works

Turn an accident, a near miss or any other issue into a lessons-learned circular. Navatom AI reads the issue and drafts what happened, why, what was done about it and what crews should do from now on, without naming anyone involved.

Circulars and issues stay linked both ways: an issue can be shared in a circular, refer to one, or be raised from one, and the circular lists the issues linked to it.

08

Manual Changes a Circular Requires

  • Name the manuals and sections to change
  • Pending updates listed until they are done
  • Completed by the section's next release
  • Navatom AI records them from the circular
How it works

When a circular changes how the fleet works, record which manuals or sections it requires to change. The manual's owners see the pending update, and the section's next release completes it, recording the version that made the change.

09

Year-Counter-Version Numbering

  • Structured identifiers: year / sequential counter / version (e.g. "5 / 2024 v2")
  • Counter auto-increments within each calendar year
  • Version number tracks revisions independently from the counter
  • Mirrors traditional maritime circular register conventions
How it works

Every circular is identified by a structured numbering scheme combining year, sequential counter, and version — producing identifiers like "5 / 2024 v2" that are instantly recognizable and traceable. The counter increments automatically within each year, and the version number tracks revisions independently.

This numbering system ensures that every circular in your fleet has a unique, human-readable identifier that conveys when it was issued, its sequence within the year, and which revision is current. The scheme mirrors the conventions that maritime professionals already use in paper-based circular registers, making the transition to digital seamless.

10

Seven-Stage Definition Lifecycle

  • Draft → Waiting for Approval → Completed → Released
  • Rejected circulars return to Draft with reviewer feedback
  • Released circulars can be Revised (new version, current stays active)
  • Deprecated circulars archived permanently, never deleted
  • Only Released circulars distributed to vessel crews
How it works

Every circular follows a controlled lifecycle through seven stages — Draft, Waiting for Approval, Completed, Rejected, Released, Revised, and Deprecated. Only Released circulars are distributed to vessels.

The lifecycle enforces that every circular passes through formal review before reaching ship personnel.

Draft circulars can be edited freely by authors. When ready, the draft is submitted for approval.

Reviewers can approve (Completed → Released) or reject (back to Draft with feedback). Released circulars can be revised, creating a new version while the current one remains active.

Deprecated circulars are archived but never deleted — maintaining a complete historical record.

11

Two Circular Types

  • Document (Word/DOCX) — full in-browser editing with rich formatting
  • PDF — upload and distribute pre-formatted circulars as-is
  • Both types follow the same seven-stage lifecycle and approval workflow
  • Format-appropriate editing and viewing experiences for each type
How it works

Navatom supports two distinct circular types — Document (Word/DOCX) for rich-text circulars that need in-platform editing with formatting, tables, and images, and PDF for pre-formatted circulars that are uploaded and distributed as-is. Each type follows the same lifecycle and distribution workflow but with format-appropriate editing and viewing experiences.

Document circulars unlock the full built-in editor for creating, revising, and formatting content directly in the browser. PDF circulars are uploaded as final-form files and distributed without modification — ideal for third-party regulatory notices, classification society bulletins, and external vendor communications.

12

Built-in Document Editor

  • Browser-based rich-text editing — no desktop software required
  • Tables, images, headers, lists, and page layout controls
  • Automatic continuous document saving
  • Edit, submit for approval, and release without leaving the platform
How it works

Create and edit Word-based circulars directly in the browser with a full-featured document editor — no desktop software required. The editor supports rich formatting, tables, images, headers, lists, and page layout controls with the same fidelity as desktop word processors.

Documents are saved automatically and continuously. The editor runs entirely within the platform — no external services, no file downloads, no version confusion.

When you're ready to distribute, the circular is submitted for approval and released to the fleet without ever leaving the system.

13

Custom Label & Categorization System

  • Create, edit, and apply custom labels to any circular
  • Categorize by topic, department, urgency, regulation, vessel type
  • Multiple labels per circular for cross-referenced categorization
  • Fully user-defined — no predefined categories to work around
How it works

Organize circulars with a flexible labeling system that adapts to your company's classification needs. Create, edit, and apply custom labels to categorize circulars by topic, department, urgency, regulation, vessel type, or any other dimension that matters to your operation.

Labels enable fast filtering and retrieval across large circular libraries. Apply multiple labels to a single circular for cross-referenced categorization.

The label system is fully user-defined — no predefined categories to work around, no limits on the number of labels you can create.

14

Published, Unpublished & Deprecated Views

  • Published — active circulars currently distributed to the fleet
  • Unpublished — drafts and circulars in the approval pipeline
  • Deprecated: out of use, and reopened in one step
  • Each view with dedicated filters and sorting options
How it works

Navigate your circular library through three dedicated list views: Published (the circulars in force, grouped by label), Unpublished (drafts, drafts waiting for approval and approved drafts), and Deprecated (circulars taken out of use, which can be reopened).

Each view provides its own set of filters and sorting options appropriate to the circular status. The Published view focuses on distribution status and read completion.

A deprecated circular can be reopened with its assignments, and the reopening is recorded.

15

Circular KPIs: Issued, Distributed and Read

  • Circulars issued and revised
  • Draft to release, approval wait and rejection rate
  • Read rate, read within 7 days and read by deadline
  • Unread crew aboard, by vessel
  • Manual changes called for and still open
How it works

24 KPIs follow a circular from draft to the crew who must read it: circulars issued and revised, days from draft to release, approval wait and rejection rate. Others show circulars left in force for over 24 months without revision, how soon a released circular is assigned to a vessel and the share of vessels it reaches.

Reading KPIs show the share of crew who have read each circular, who read it within 7 days or by their deadline, the Master's time to read, the crew aboard who have not yet read one and what new joiners have caught up on. Follow-up KPIs count the manual changes a circular calls for that are still open and the days it takes to make them.

16

Multi-Format Storage & Conversion

  • Written in Word, read as PDF
  • Server-side format conversion with full fidelity
  • PDF circulars uploaded as they are
  • Formatting, tables, and images preserved across conversions
How it works

Each circular is written in Word in the browser, and Navatom builds the PDF the crew read and print from that single source file. A PDF circular, such as a flag State notice, is uploaded as it is.

Conversion happens server-side with full fidelity: formatting, tables, images, and layout are preserved. Your circulars are always ready to read in the browser, print on board, or archive for compliance.

17

Comments & Collaboration

  • Threaded comments attached to specific circulars
  • Add, edit, and delete comments with full attribution
  • Comment threads persist across circular versions
  • Comment activity recorded in the audit trail
How it works

Add threaded comments to any circular for collaborative review and feedback. Comments support adding, editing, and deletion — creating a structured discussion thread attached to the specific circular being reviewed. Comment threads persist across versions for continuity.

Use comments during the approval process to provide specific feedback on content, request clarifications, or document review decisions. Comment history is preserved as part of the circular's audit trail, providing evidence of the review process for compliance auditors.

18

Dashboard & Analytics

  • Total Circulars — size of your circular library
  • Released This Year — publication cadence tracking
  • Awaiting Approval — review bottleneck identification
  • Completed: approved circulars ready to publish
  • Fleet-wide aggregation with single-pane monitoring
How it works

Monitor your circular program with four dashboard widgets: Total Circulars shows the size of your circular library, Released This Year tracks publication cadence, Awaiting Approval highlights review bottlenecks, and Completed counts the approved circulars ready to publish.

Dashboard metrics aggregate across your entire fleet, providing shore management with a single-pane view of circular communication health. Each circular's assignments show its read share per ship, and Navatom AI tells you who on a vessel has not read it.

19

Complete Audit Trail

  • Every action, from creation to deprecation
  • Every read and assignment change
  • Full user attribution and timestamp on every event
  • Complete traceability from draft to fleet-wide distribution
How it works

Every action on a circular is recorded as it happens, with who did it and when, from creation through editing, approval, rejection, release, distribution, every read, revision, and deprecation.

The same record feeds the audit trail, notifications and dashboards. Auditors can trace every circular's journey from draft to fleet-wide distribution with complete accountability for every decision and action along the way.

FAQ

Frequently Asked Questions

Common questions about Circulars answered.

What types of circulars does the module support?

Navatom Circulars supports two types: Document (Word/DOCX) for rich-text circulars that can be created and edited directly in the built-in editor, and PDF for pre-formatted circulars that are uploaded and distributed as-is. Both types follow the same seven-stage lifecycle, approval workflow, and distribution system. Document circulars are ideal for company-authored notices that may go through multiple revisions, while PDF circulars are perfect for distributing third-party regulatory notices and vendor bulletins.

How does the approval workflow work?

Authors write circular drafts and send them for approval. The circular's category names the group whose members approve, and any one of them either approves it (moving to Completed status) or rejects it with feedback (returning it to the author). Approved circulars are then published to the fleet. If a published circular needs updating, revising it opens a new draft while the current version stays in force until the revision is approved and published.

Can I target specific ships and crew ranks?

Yes. Assign each circular to ships or ship groups and choose which of 51 onboard ranks must read it, with the days they have to read it. A tanker-specific operational directive can be targeted only to your tankers and only to the ranks that need to act on it: master, chief engineer, or any combination of positions. Distribution assignments can be modified after release without requiring a new version.

How do I know crews have read the circular?

Mark a circular as read-required, and each crew member in the assigned ranks confirms it on the ship app by typing "read and understood". The circular's assignments show each ship's read share and, ship by ship, who has read it and who has not, and the Captain sees the same for the whole ship on board. Crew who have not read it are reminded when it falls due and again when it is overdue.

Does the module track changes between versions?

Yes. When a circular is revised, Navatom compares the new version with the one before, and its change log shows the comparison with insertions and deletions marked. The published version stays in force until the revision is published, and the complete version history is preserved permanently for compliance auditing.

Does the module work offline on vessels?

Yes. The circulars assigned to a vessel are kept on the crew's device, so crew can read them with no connection, and their reading confirmations are sent when the connection returns. Crew can also read them in the Navatom mobile app for iPhone and Android, offline.

Are crew reminded to read a circular?

Yes. Set the days the crew have to read a circular, on the circular or as its category's default. Crew who have not read it get a reminder when it falls due and another when it is overdue, once for each new version.

What happens when a circular expires?

Give a circular a valid-until date, and it is deprecated automatically after its last day in force, so crew stop seeing it. The circulars expiring soon are listed, and a deprecated circular can be reopened.

Can a circular come from an accident or near miss?

Yes. Navatom AI drafts a lessons-learned circular from an issue: what happened, why, what was done and what crews should do now, without naming anyone involved. The circular and the issue stay linked.

Navatom AI

Ask Navatom AI about Circulars

Navatom AI reads circulars and who has confirmed reading them, drafts new circulars, including one from a Word file you give it, and proposes revisions paragraph by paragraph as tracked changes.

  • Who on MT Boreas has not read the latest bunkering circular?
  • Draft a lessons-learned circular from this near miss.
  • Which manual sections does this circular require us to change?
  • Show me the circulars waiting for my approval.

Every draft goes through the circular’s own approval, and a lessons-learned circular leaves out who was involved.
