What Is the ISM Code?
The International Safety Management Code is known as the ISM Code. It is the international standard for the safe management and operation of ships at sea. The International Maritime Organization adopted it in 1993 through Resolution A.741(18). SOLAS Chapter IX made it mandatory.
The Code applies to all passenger ships, oil tankers, chemical tankers, gas carriers, bulk carriers and cargo high-speed craft. They must be 500 gross tonnage or more and sail on international voyages. Its main purpose is to set an international standard for safe ship management and operation. The standard also covers pollution prevention.
The ISM Code asks each company that operates these ships to set up a Safety Management System, or SMS. The SMS records the policies, procedures and instructions for safe ship operation and for protecting the environment. Audits must be able to verify it. The flag state administration conducts these audits, or a recognized organization acting for it.
A company that meets the requirements receives a Document of Compliance (DOC). Each ship receives a Safety Management Certificate (SMC). Both certificates must be renewed, typically every 5 years. Intermediate verification audits fall in between.
The ISM Code has been revised several times since its adoption. The changes reflect new industry practices and lessons from maritime casualties. The most significant amendments cover cyber risk management, introduced in 2021. They also cover updated guidance on goal-based standards.
For ship managers, the ISM Code is more than a box to tick. It is the backbone of how a company governs its operations. It directly affects the company's ability to trade, insure and charter its vessels.
Audits verify compliance with the ISM Code in two levels. First, the company must show that its shore-based management system meets the Code's requirements. Then each ship is audited on its own. The audit confirms that the SMS is properly applied on board.
Without a valid DOC or SMC, a ship can be detained by port state control. It can lose class. Insurers can withdraw coverage. So ISM compliance is a commercial need as much as a safety one.
Core Requirements
The ISM Code has 16 sections. Of these, 13 define the functional requirements that a company's Safety Management System must address. Each area sets specific duties for both shore-based management and shipboard personnel.
Together they form a framework that covers each aspect of safe ship operation. It runs from high-level policy setting to handling day-to-day emergencies. The list below sums up the 13 core functional areas that companies must address in their SMS.
- General: Safety and environmental protection policy
- Company responsibilities and authority
- Designated Person Ashore (DPA)
- Master's responsibility and authority
- Resources and personnel: training, qualifications, and competence
- Development of plans for shipboard operations
- Emergency preparedness
- Reports and analysis of non-conformities, accidents, and hazardous occurrences
- Maintenance of the ship and equipment
- Documentation
- Company verification, review, and evaluation
- Certification and verification by flag state or recognized organization
- Forms of certificates (DOC and SMC)
Among these, the Designated Person Ashore holds a critical role. The DPA is the direct link between shore management and shipboard operations. The DPA also has direct access to the highest level of management.
The DPA monitors the safety and pollution prevention side of each ship's operation. The DPA also makes sure that enough resources and shore-based support are in place. In practice, the DPA often leads the work during audits, incident investigations and management reviews.
The documentation requirements under Section 11 are extensive. All SMS documents must be controlled. This means that obsolete versions are removed from use. It also means that authorized personnel review and approve changes before distribution.
This covers policy manuals, procedures, checklists and emergency contact lists. It also covers records of drills, maintenance and non-conformity resolution. The sheer volume of documents is one of the heaviest parts of ISM compliance. So is controlled distribution across many vessels and shore offices.
Section 12 sets out internal audits. The company must check regularly whether safety and pollution prevention work complies with the SMS. Audit findings must reach the people responsible for the area audited. Management must then take timely corrective action.
The ISM Code demands continuous improvement. Audit results and management reviews feed directly into it.
Common Challenges in ISM Compliance
The ISM Code has been in force for over three decades. Yet many ship managers still struggle to put it into practice. The most persistent challenge is that many Safety Management Systems are paper-based.
When SMS documents are printed manuals sent to each vessel, version control becomes a heavy burden. A single change to a procedure may mean printing and sending it. Crews must confirm receipt and withdraw the old version. This happens across a whole fleet. The process is slow, error-prone and hard to verify.
Audit preparation is another area where companies lose a lot of time. Internal and external audits need evidence from many departments and vessels. That means maintenance records, drill reports and non-conformity logs. It also means training certificates, management review minutes and more.
The evidence is often scattered across spreadsheets, email threads, filing cabinets and standalone databases. Putting together a complete audit package can then take weeks of staff time. The DPA usually coordinates audit preparation. The DPA often becomes a bottleneck while chasing documents from superintendents, masters and department heads.
Non-conformity management has its own difficulties. The ISM Code asks companies to report non-conformities, accidents and hazardous occurrences. They must then investigate them and resolve them with corrective actions.
In practice, companies often lose track of open findings. This happens most when a corrective action passes between shipboard and shore-based staff. Without a systematic follow-up, findings may stay unresolved for months. This applies to findings from port state control inspections, internal audits and vetting inspections. They turn into recurring observations that auditors flag on later visits.
Gaps in shore-ship communication make compliance harder. Masters and officers at sea may lack immediate access to the latest SMS revisions. The same goes for policy updates and safety circulars.
The reverse also happens. Shore-based management may not see shipboard compliance work in real time. These include drill completion, maintenance work and near-miss reporting. The shore can then believe the fleet is compliant. Meanwhile, some vessels run on outdated procedures or incomplete records.
Finally, the human element remains a challenge. Some crew members see the SMS as a paperwork exercise, not as a practical safety tool. They are less likely to follow procedures carefully or to report non-conformities early.
A real safety culture needs an SMS that is practical and easy to reach. It must be clearly useful to the people who use it every day. Systems that are clumsy, outdated or cut off from actual operations work against this.
How Software Supports ISM Compliance
Ship management software supports ISM Code requirements. It digitizes the Safety Management System. It connects shore and ship operations on a single platform. The most immediate benefit is document version control.
A good system shows users only the current, approved version of any procedure, checklist or form. When someone revises a document, the system sends out the new version by itself. It records who has acknowledged it. It also archives the old version with a full audit trail. This removes the risk of vessels working with outdated procedures.
Software makes non-conformity tracking systematic. Each finding is recorded with its root cause analysis, corrective action plan, responsible person and deadline. This holds for findings raised internally or by an external auditor.
The system sends reminders as deadlines approach. It escalates overdue items. It also asks for evidence of closure before a finding can be marked as resolved. This closed-loop workflow means nothing falls through the cracks. Auditors get clear evidence of timely corrective action.
Software also helps with emergency preparedness. It handles drill scheduling and record-keeping. The system can keep a drill calendar. The calendar follows regulatory requirements, each vessel's schedule and crew rotation.
After each drill, the master records the outcome, participants, lessons learned and any deficiencies seen. Managers ashore can follow drill completion across the fleet in real time. This shows which vessels are falling behind on drills. The gap is visible before it becomes a compliance issue.
Internal audit management gets simpler when one system handles the whole audit cycle. Audit plans, checklists, findings, corrective actions and follow-up checks can all be tracked from start to closure.
Past audit data allows trend analysis. It helps management spot recurring issues and systemic weaknesses in the SMS. This data-driven approach supports the duty of continuous improvement under Section 12 of the Code.
Most important, software gives real-time shore-ship visibility. Management ashore can see the current state of SMS compliance on each vessel. They do not have to wait for monthly reports or email updates.
This covers maintenance completion rates, open non-conformities and drill status. It also covers document acknowledgment and risk assessment results. A live dashboard helps the DPA meet the monitoring duty. Snapshots put together by hand from different sources do this less well.
How Navatom Helps
Navatom is a cloud-based ship management platform with 40+ integrated modules. Each one supports a different part of ISM Code compliance. Navatom does not bolt on a standalone compliance tool. It builds ISM requirements into the workflows that ship managers already use every day.
So compliance data comes as a byproduct of normal operations. It is not an extra administrative burden.
The Planned Maintenance System module supports Section 10 of the ISM Code. It schedules, tracks and records all maintenance work for ship machinery and equipment. Maintenance jobs link to specific equipment. Each has set intervals, spare part requirements and completion criteria.
The system flags overdue maintenance. Completion records are stored with full traceability. So the company can show auditors that maintenance meets the SMS and applicable regulations. This covers the ship and its equipment.
The Document Management module supports Section 11. It controls the distribution of all SMS documents. Each document has a defined owner, a revision history and an approval workflow.
Distribution is automatic. The system tracks acknowledgment by each recipient. Obsolete versions are archived and cannot be used in operations.
Fleets differ in size and type. The module supports vessel-specific document sets. It also keeps a common core SMS across the company.
The Non-Conformity module covers Section 9 requirements. Its structured workflow handles reporting, investigating and closing findings. Each non-conformity is sorted by type and severity. It gets a root cause analysis. It links to corrective and preventive actions. Each action has a clear deadline and a responsible person.
The module supports findings from any source. Sources include internal and external audits, port state control inspections, vetting inspections and voluntary crew reports. Management can follow non-conformity status across the fleet on dashboards. They show open items, overdue actions and resolution trends.
The Drills and Emergency module supports Section 8. It schedules the drills that SOLAS and flag state requirements demand. It records participation and outcomes. It also tracks follow-up actions from drill debriefings. The Risk Assessment module supports the hazard identification and risk evaluation that the SMS calls for.
The Audit Management module handles the internal audits that Section 12 calls for. It covers planning, execution and follow-up. It has customizable checklists and workflows for resolving findings.
All these modules run on a single cloud platform, so data flows between them. An internal audit may find a maintenance deficiency. It can be raised as a non-conformity and linked to a corrective maintenance job. It can be tracked to closure without switching systems or re-entering data.
This integration removes data silos. These trouble companies that use a patchwork of standalone tools. It also gives the DPA a unified view of SMS performance across the entire fleet.
