What Is the ISM Code?
The International Safety Management Code, commonly known as the ISM Code, is the international standard for the safe management and operation of ships at sea. It was adopted by the International Maritime Organization in 1993 through Resolution A.741(18) and made mandatory under SOLAS Chapter IX. The Code applies to all passenger ships, oil tankers, chemical tankers, gas carriers, bulk carriers, and cargo high-speed craft of 500 gross tonnage and above engaged on international voyages. Its fundamental purpose is to provide an international standard for the safe management and operation of ships and for pollution prevention.
The ISM Code requires every company operating applicable ships to establish a Safety Management System, or SMS, that documents policies, procedures, and instructions for safe ship operation and environmental protection. The SMS must be verifiable through audits conducted by the flag state administration or a recognized organization acting on its behalf. Companies that satisfy the requirements receive a Document of Compliance (DOC), while individual ships receive a Safety Management Certificate (SMC). Both certificates must be renewed periodically, typically every five years, with intermediate verification audits.
Since its adoption, the ISM Code has been revised several times to reflect evolving industry practices and lessons learned from maritime casualties. The most significant amendments include provisions for cyber risk management introduced in 2021 and updated guidance on goal-based standards. For ship managers, the ISM Code is not merely a regulatory checkbox; it forms the backbone of operational governance and directly influences a company's ability to trade, insure, and charter its vessels.
Compliance with the ISM Code is verified through a two-tier audit process. The company must first demonstrate that its shore-based management system meets the Code's requirements, and then each ship must be individually audited to confirm that the SMS is effectively implemented on board. Failure to maintain a valid DOC or SMC can result in port state control detentions, loss of class, and withdrawal of insurance coverage, making ISM compliance a commercial imperative as much as a safety one.
Core Requirements
The ISM Code is organized into 16 sections, of which 13 define the functional requirements that a company's Safety Management System must address. Each functional area prescribes specific obligations for both shore-based management and shipboard personnel. Together they form a comprehensive framework covering every aspect of safe ship operation, from high-level policy setting to the handling of day-to-day emergencies. The following list summarizes 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 particularly critical role. The DPA serves as the direct link between shore management and shipboard operations, with direct access to the highest level of management. The DPA is responsible for monitoring the safety and pollution prevention aspects of the operation of each ship and for ensuring that adequate resources and shore-based support are applied as required. In practice, the DPA often acts as the primary coordinator during audits, incident investigations, and management reviews.
The documentation requirements under Section 11 are extensive. All SMS documents must be controlled, meaning that obsolete versions are removed from use and that amendments are reviewed and approved by authorized personnel before distribution. This includes policy manuals, operational procedures, checklists, emergency contact lists, and records of drills, maintenance, and non-conformity resolution. The sheer volume of documentation and the need for controlled distribution across multiple vessels and shore offices is one of the most resource-intensive aspects of ISM compliance.
Internal audits under Section 12 require the company to periodically verify whether safety and pollution prevention activities comply with the SMS. Audit findings must be brought to the attention of personnel responsible for the area audited, and management must take timely corrective action. The results of audits and management reviews feed directly into the continuous improvement cycle that the ISM Code demands.
Common Challenges in ISM Compliance
Despite the ISM Code having been in force for over three decades, many ship management companies still struggle with implementation. The most persistent challenge is the paper-based nature of many Safety Management Systems. When SMS documents exist as printed manuals distributed to each vessel, version control becomes a significant burden. A single change to an operational procedure may require printing, distributing, acknowledging receipt, and withdrawing the superseded version across an entire fleet. This process is slow, error-prone, and difficult to verify.
Audit preparation is another area where companies lose significant time. Internal and external audits require gathering evidence from multiple departments and vessels: maintenance records, drill reports, non-conformity logs, training certificates, management review minutes, and more. When this evidence is scattered across spreadsheets, email threads, filing cabinets, and standalone databases, assembling a complete audit package can consume weeks of staff time. The DPA, who typically coordinates audit preparation, often becomes a bottleneck as they chase documentation from superintendents, masters, and department heads.
Non-conformity management presents its own difficulties. The ISM Code requires that non-conformities, accidents, and hazardous occurrences be reported, investigated, and resolved with corrective actions. In practice, companies frequently lose track of open findings, particularly when corrective action responsibility transfers between shipboard and shore-based personnel. Without a systematic follow-up mechanism, findings from port state control inspections, internal audits, or vetting inspections may remain unresolved for months, creating recurring observations that auditors flag during subsequent visits.
Shore-ship communication gaps further complicate compliance. Masters and officers at sea may not have immediate access to the latest SMS revisions, policy updates, or safety circulars. Conversely, shore-based management may lack real-time visibility into shipboard compliance activities such as drill completion, maintenance execution, and near-miss reporting. This information asymmetry can lead to situations where the shore believes the fleet is compliant, while individual vessels are operating with outdated procedures or incomplete records.
Finally, the human element remains a challenge. Crew members who view the SMS as a bureaucratic exercise rather than a practical safety tool are less likely to follow procedures diligently or report non-conformities proactively. Building a genuine safety culture requires that the SMS be practical, accessible, and demonstrably useful to the people who interact with it daily. Systems that are cumbersome, outdated, or disconnected from actual operations undermine this objective.
How Software Supports ISM Compliance
Ship management software addresses ISM Code requirements by digitizing the Safety Management System and connecting shore and ship operations on a single platform. The most immediate benefit is document version control. A well-designed system ensures that only the current, approved version of any procedure, checklist, or form is available to users. When a document is revised, the system automatically distributes the new version, records acknowledgment by relevant personnel, and archives the superseded version with a full audit trail. This eliminates the risk of vessels operating with outdated procedures.
Non-conformity tracking becomes systematic when managed through software. Each finding, whether raised internally or by an external auditor, is recorded with its root cause analysis, corrective action plan, responsible person, and deadline. The system sends automated reminders as deadlines approach, escalates overdue items, and requires evidence of closure before a finding can be marked as resolved. This closed-loop workflow ensures that nothing falls through the cracks and provides auditors with clear evidence of timely corrective action.
Emergency preparedness benefits from software through drill scheduling and record-keeping. The system can maintain a drill calendar that accounts for regulatory requirements, vessel-specific schedules, and crew rotation. After each drill is conducted, the master records the outcome, participants, lessons learned, and any deficiencies observed. Shore management can monitor drill completion across the fleet in real time, identifying vessels that are falling behind on required exercises before the gap becomes a compliance issue.
Internal audit management is streamlined when the entire audit cycle is handled within a single system. Audit plans, checklists, findings, corrective actions, and follow-up verification can all be tracked from initiation to closure. Historical audit data enables trend analysis, helping management identify recurring issues and systemic weaknesses in the SMS. This data-driven approach supports the continuous improvement obligation under Section 12 of the Code.
Perhaps most importantly, software provides real-time shore-ship visibility. Management ashore can see the current state of SMS compliance across every vessel without waiting for monthly reports or email updates. This includes maintenance completion rates, open non-conformities, drill status, document acknowledgment, and risk assessment results. The DPA can fulfill their monitoring obligation more effectively when they have a live dashboard rather than periodic snapshots assembled manually from disparate sources.
How Navatom Helps
Navatom is a cloud-based ship management platform with over 30 integrated modules, each contributing to different aspects of ISM Code compliance. Rather than bolting on a standalone compliance tool, Navatom embeds ISM requirements into the operational workflows that ship managers already use daily. This means that compliance data is generated as a byproduct of normal operations, not as an additional administrative burden.
The Planned Maintenance System module directly supports Section 10 of the ISM Code by scheduling, tracking, and recording all maintenance activities for ship machinery and equipment. Maintenance jobs are linked to specific equipment, with defined intervals, spare part requirements, and completion criteria. Overdue maintenance is flagged automatically, and completion records are stored with full traceability. This ensures that the company can demonstrate to auditors that the ship and its equipment are maintained in conformity with the SMS and applicable regulations.
The Document Management module addresses Section 11 by providing controlled distribution of all SMS documentation. Every document has a defined owner, revision history, and approval workflow. Distribution is automatic, and the system tracks acknowledgment by each recipient. Obsolete versions are archived and inaccessible for operational use. For companies managing fleets of varying sizes and types, the module supports vessel-specific document sets while maintaining a common core SMS across the organization.
The Non-Conformity module handles Section 9 requirements with a structured workflow for reporting, investigating, and closing findings. Each non-conformity is categorized by type and severity, assigned a root cause analysis, and linked to corrective and preventive actions with clear deadlines and responsible personnel. The module supports findings from any source, including internal audits, external audits, port state control inspections, vetting inspections, and voluntary crew reports. Management can monitor the fleet-wide non-conformity status through dashboards that show open items, overdue actions, and resolution trends.
The Drills and Emergency module supports Section 8 by scheduling mandatory drills according to SOLAS and flag state requirements, recording participation and outcomes, and tracking follow-up actions from drill debriefings. The Risk Assessment module supports hazard identification and risk evaluation processes required throughout the SMS. The Audit Management module handles the planning, execution, and follow-up of internal audits required under Section 12, with customizable checklists and finding resolution workflows.
Because all these modules operate on a single cloud platform, data flows naturally between them. A maintenance deficiency discovered during an internal audit can be raised as a non-conformity, linked to a corrective maintenance job, and tracked to closure without switching between separate systems or re-entering data. This integration eliminates the data silos that plague companies using a patchwork of standalone tools and gives the DPA a unified view of SMS performance across the entire fleet.
