Since the implementation of IACS UR E27, many equipment suppliers have chosen to demonstrate compliance through a Statement of Compliance (SoC) — or in the case of ClassNK, a Statement of Fact (SoF). While pragmatic, one fundamental question remains: Is an SoC-centered strategy optimal from a long-term perspective? UR E27 is not merely a project-level requirement — it is a framework that affects product repeatability, lifecycle management, and market credibility.

Ⅰ. Problem Statement: Is SoC-Centric Approach Sufficient?

This approach can be understood as a pragmatic decision aimed at reducing schedule pressure and managing initial compliance risk. However, when UR E27 is viewed through the lens of product repeatability, lifecycle management, and market credibility, the supplier certification strategy warrants a more structural and strategic review.

UR E27 is not merely a project-level requirement. The supplier certification strategy warrants a more structural and strategic review than a simple compliance checkbox.

Ⅱ. Is There a Significant Difference in Preparation Structure?

From a practical standpoint, both SoC and Type Approval (TA) require largely the same foundational elements:

  • Cyber security architecture description
  • Definition of security functions and configuration management
  • Test procedures and execution of testing
  • Survey attendance or technical review response
  • Consolidation of evidence documentation
The common perception that SoC is a "simple certification" while TA is a "complex certification" is not entirely accurate when viewed strictly from a preparation perspective. The distinction lies not in the preparation items themselves, but in the nature of the approval framework.

Ⅲ. The Fundamental Structural Difference

The core difference between SoC and TA is not the level of effort required for preparation, but rather the character of the approval and the associated responsibility framework.

Category SoC Type Approval (TA)
Approval Object Specific condition / defined scope The product itself
Scope of Application Project-based Repeatable application
Class Responsibility Limited confirmation Approval with accountability
Change Management Re-evaluation possible upon change Integrated type approval change control system
Market Credibility Reference-level document Formal certification
Cross-Class Portability Limited Strong reference effect
SoC

Confirming that "the system complies under defined conditions."

Type Approval

Approving that "the product is suitable for repeated application."

This is not merely a documentary distinction. It is a difference in regulatory effect and structural positioning.

Ⅳ. Analysis of Major Classification Society Practices

A comparative review of major classification societies' approaches to UR E27 shows that Type Approval is generally positioned as the primary approval mechanism, while SoC is applied in a limited or conditional context.

  • DNV Operates a dedicated cyber security Type Approval program
  • ABS Maintains a product-level Type Approval and Product Design Assessment (PDA) framework
  • LR Operates a Type Approval scheme explicitly designed for repeat installations
  • BV Applies a TA-centered system incorporating design review and testing
  • KR Adopts a documentation review, testing, and audit-based approval structure aligned with product-level certification
The pattern is consistent. UR E27 is structurally aligned with product-level repeatability, and TA is the formal mechanism through which that repeatability is institutionalized.

Ⅴ. Differences in Industrial Impact

The structural difference between SoC and TA translates into tangible industrial consequences across five dimensions:

Procurement
A product holding TA provides structural credibility during shipowner and shipyard vendor evaluations.
Repeatability
Where the same product is installed across multiple vessels, TA reduces repetitive review and clarification cycles.
Change Mgmt.
TA incorporates a formal change control framework, supporting lifecycle stability.
Cross-Society
A strong TA from one major society often serves as a technical reference in discussions with other societies.
Cost Structure
While SoC may appear lighter short-term, cumulative project-by-project compliance costs can outweigh the initial investment in TA.

Ⅵ & Ⅶ. When Is TA Advantageous — and When Is It Not?

✅ TA is particularly advantageous
  • ✓ Same product delivered to multiple vessels simultaneously
  • ✓ Operations span multiple classification societies and shipyards
  • ✓ Long-term product platform expansion is planned
  • ✓ Vendor evaluation criteria emphasize formal type approval
  • ✓ Repeated delivery and long-term service agreements expected
⚠ TA may be less optimal
  • – One-off or limited-scope project deliveries
  • – Early-stage products with unstable design baselines
  • – Restricted market exposure
  • – Highly compressed delivery schedules
  • – Equipment falling within negligible-risk categories

Ⅷ. Strategic Conclusion

The UR E27 response strategy should not be framed as a binary choice between SoC and TA. Instead, it should be determined by evaluating product repeatability, market expansion objectives, design maturity, and procurement strategy. However, from a long-term structural perspective, UR E27 is aligned with product-level approval frameworks.

📋
SoC

Resolves a project requirement

Short-term compliance mechanism
🏆
Type Approval

Establishes product credibility and market position

Strategic long-term positioning
Final Core Message

SoC is a short-term compliance mechanism.
TA is a strategic approval that secures long-term market positioning.

TA therefore represents not merely a stricter certification pathway, but a strategic instrument for strengthening a supplier's structural competitiveness.
