SFI Coding and ISO 14224: A Complete Guide for Maritime CMMS
How combining two industry standards can transform your maintenance data quality
Introduction: The Hidden Challenge in Maritime Maintenance
Picture this: A chief engineer on an offshore supply vessel needs to order a replacement seal for the stern tube forward assembly. In their CMMS—whether it's AMOS, Maximo, or another platform—they search for the part. But is it under "propulsion systems," "shaft sealing," or "stern equipment"? Without standardized coding, finding the right component becomes a time-consuming treasure hunt through inconsistent data structures.
This scenario plays out thousands of times daily across the global shipping fleet, costing the industry millions in inefficiencies. Recent studies found that unplanned downtime costs industrial manufacturers an estimated $50 billion annually, with maritime operations bearing a significant portion of these losses.
Enter SFI coding and ISO 14224—two powerful standards that, when combined, create a comprehensive framework for maritime CMMS data quality that can transform how shipping companies manage their maintenance operations.
Understanding SFI: The Maritime Industry's Universal Language
What is SFI Coding?
The SFI Group System is the most widely-used classification system for maritime and offshore industries worldwide, tying together all vessel management functions, such as operations, purchasing, accounting, maintenance, quality, etc. Originally developed in 1972 by the Ship Research Institute of Norway, SFI has become the de facto standard for organizing ship information.
The Structure of SFI Coding
SFI introduces a code structure including group, sub-group and detail codes, each related to a certain degree of detail or system size, making it possible to control every element inside a ship by simply associating that element to a 6-digit code.
The hierarchical structure works as follows:
- Main Group (1 digit): Major ship function (e.g., 6 = Machinery main components)
- Group (2 digits): System level (e.g., 60 = Diesel engines for propulsion)
- Sub-group (3 digits): Component type (e.g., 601 = Diesel engines)
- Detail Code (6 digits): Specific component (e.g., 601001 = Main diesel engine)
Real-World Application
When a shipping company orders spare parts, these may be identified by the SFI Detail Code + consecutive numbers (total of 9-10 digits), creating a universal identification system that works across shipyards, suppliers, and operators globally.
For example, that stern tube seal mentioned earlier? It would be coded as 735.007 in the SFI system—instantly recognizable to any maritime professional worldwide, regardless of their CMMS platform or native language.
ISO 14224: The Data Quality Framework
Defining ISO 14224
ISO 14224:2016 provides a comprehensive basis for the collection of reliability and maintenance (RM) data in a standard format for equipment in all facilities and operations within the petroleum, natural gas and petrochemical industries during the operational life cycle of equipment. While originally designed for oil and gas, its principles apply perfectly to maritime operations, especially offshore vessels.
Core Components of ISO 14224
The standard focuses on three main data categories:
- Equipment Data: Taxonomy, attributes, and classification
- Failure Data: Failure causes, consequences, and modes
- Maintenance Data: Actions taken, resources used, downtime tracking
It describes data collection principles and associated terms and definitions that constitute a "reliability language" that can be useful for communicating operational experience.
The Power of Standardized Failure Modes
ISO 14224 introduces structured hierarchies such as functional locations (FLOCs), equipment classes, and failure modes, which are vital when implementing systems or migrating to advanced CMMS platforms. This standardization enables:
- Benchmarking across vessels and fleets
- Predictive maintenance modeling
- Root cause analysis
- Industry-wide knowledge sharing
The Synergy: How SFI and ISO 14224 Work Together
Complementary Strengths
While SFI provides the "what and where" (equipment identification and location), ISO 14224 delivers the "how and why" (failure modes and maintenance strategies). Together, they create a complete data ecosystem for maritime CMMS systems.
Consider a main engine cooling pump failure:
- SFI Code 641.001: Identifies the exact pump and its location in the ship's hierarchy
- ISO 14224 Data: Captures failure mode (e.g., seal leak), maintenance action (replacement), downtime (4 hours), and root cause (normal wear)
This combination enables fleet managers to track not just what failed, but why it failed and how to prevent future occurrences across similar equipment.
Integration in Modern CMMS Platforms
The technical accounts of planned maintenance systems such as AMOS Maintenance and Procurement are commonly based on the SFI Group System. When combined with ISO 14224 data structures, these platforms can:
- Automate Work Order Generation: SFI codes trigger specific maintenance tasks based on ISO 14224 reliability data
- Enable Predictive Analytics: Historical failure patterns linked to specific SFI codes predict future maintenance needs
- Optimize Spare Parts Inventory: Combine SFI identification with ISO 14224 failure rates for precise stocking levels
- Facilitate Regulatory Compliance: Both standards support ISM Code and class society requirements
Implementation Best Practices for Shipping Companies
Getting Started with Dual Implementation
Based on industry best practices, here's a phased approach to implementing both standards:
Phase 1: Establish Your Foundation (Months 1-3)
- Map existing equipment to SFI codes: Start with critical machinery
- Define ISO 14224 equipment boundaries: Clear scope for data collection
- Train key personnel: Focus on maintenance managers and CMMS administrators
- Select pilot vessels: Choose 2-3 ships for initial rollout
Phase 2: Data Collection and Standardization (Months 4-6)
ISO 14224 provides the guidelines on the categories of maintenance work and the related activities. By enforcing semi-rigid definitions and monitoring on a frequent basis, maintenance work coming through the CMMS can be categorized.
Key activities include:
- Standardizing failure codes across the fleet
- Creating maintenance task libraries linked to SFI codes
- Establishing data quality KPIs
- Building reporting templates
Phase 3: System Integration (Months 7-9)
- Configure CMMS to support both standards
- Develop automated workflows
- Create dashboards for real-time monitoring
- Establish data governance procedures
Phase 4: Continuous Improvement (Ongoing)
- Benchmark against industry peers
- Refine failure codes based on experience
- Expand to additional vessel types
- Share learnings across the fleet
Overcoming Common Challenges
Challenge 1: Resistance to Change Solution: Demonstrate quick wins through improved spare parts location (SFI) and reduced repeat failures (ISO 14224)
Challenge 2: Data Migration Complexity Solution: Use automated mapping tools and validate in phases rather than attempting complete migration at once
Challenge 3: Training Requirements Solution: Develop role-specific training—simplified for deck officers, detailed for superintendents
Challenge 4: Inconsistent Legacy Data Solution: Focus on "going forward" data quality while gradually cleaning historical records
Maximizing ROI Through Data Quality
Quantifiable Benefits
When properly implemented, the combination of SFI and ISO 14224 delivers measurable returns:
- Reduced Search Time: 70% faster equipment and spare parts location

Case Study: Offshore Support Vessel Fleet
In the oil and gas sector, where downtime can cost $220,000 per hour, ISO 14224 enables better decision-making by providing standardized templates for preventive maintenance (PM) and risk-based inspections.
A North Sea operator implementing both standards achieved:
- 30% reduction in unplanned downtime
- €2.3 million annual savings in maintenance costs
- 45% improvement in spare parts availability
- 60% faster troubleshooting for complex failures
