IACS UR E26 / E27 Compliance

Settle system types late, and the schedule slips.

The scope of documents to submit is fixed only once system types are confirmed. We settle types at maker selection and re-assess risk at every stage.

  1. 01Maker selection · quotation

    If types are settled late

    Unable to explain whether UR E27 applies.

    Gwangmyung Maritime

    RA 1 · Types confirmed at selection; class guidance provided

  2. 02Approval drawings

    If types are settled late

    Repeated class comments due to inadequate definition of security functions and external interfaces.

    Gwangmyung Maritime

    RA 2 · Threat exposure paths assessed from drawings and cabling

  3. 03FAT

    If types are settled late

    Account management, logging, backup and recovery, and remote access controls found to fall short.

    Gwangmyung Maritime

    RA 3 · Controls assessed against the real operating environment

  4. 04Delivery

    If types are settled late

    Software and network architecture changes and a delivery-schedule adjustment are required, and the yard reviews alternative suppliers.

System type classification

The scope of documents to submit is fixed only once each system’s type is confirmed. An unconfirmed type is a schedule risk in itself.

Non-CBS
Not a computer-based system (CBS) under the UR E26 criteria
Non-CBS supporting evidence required
Out-of-Scope
A CBS, but outside the UR E26 1.3.2 scope of application
Out-of-scope supporting evidence required
Exclusion
A CBS, but excluded from requirement application under the UR E26 6.4 acceptance criteria
Exclusion supporting evidence required
Target
A CBS that falls under none of the above, and is therefore subject to UR E26
Full design documentation submission mandatory
Three-phase risk assessment for early type confirmation

Submission scope remains fluid until system types are confirmed, so we re-assess risk at every stage from maker selection onward.

RA PHASE 1

Maker Selection

  • Early identification at selection
  • Class guidelines + 1:1 classification
  • Upfront supplier consultation

RA PHASE 2

Drawing & Cabling

  • Stage 1 type + asset information
  • Integrated drawing · cabling review
  • Threat exposure path assessment

RA PHASE 3

Operating Environment

  • Reflects the actual operating environment
  • Response capability · level of control
  • Assessment against known threats

Three-tier scope of ship cyber resilience mandate

Responsibility expands across E26 (ship-wide) → E27 (per-system) → SCARP (operation lifecycle).

E26
Establishes the ship-wide cyber security concept and management framework.
E27
Requires design and operation that presume cyber security in each system.
SCARP
Runs the ship cyber resilience programme continuously in the operation phase.

UR E27 supplier readiness

Products that cannot explain and demonstrate UR E27 conformity become hard to select during a yard’s design, procurement and approval process.

TA · SoC · SoF — means of demonstrating conformity, not a grade

TA Type Approval
Suited to suppliers repeatedly delivering the same standard product to multiple yards and vessels.
SoC Statement of Compliance
A realistic starting point when a specific product version or project takes priority.
SoF Statement of Fact
Focused on the design approval and product inspection procedures of an individual vessel project.

Responding to UR E27 is not about obtaining a certificate — it is about building both the product’s security capability and the engineering system that produces and sustains it.
