Unified requirements e26 & e27: what, why & when

This article was updated in Autumn 2023 after the International Association of Classification Societies (IACS) revised their initial guidance. The two new Unified Requirements, E26 and E27, were due to be launched from the 1st of January 2024 however this has now been changed to the 1st of July 2024. These changes are a result of industry feedback and the need for standardisation across the maritime industry.


IACS have announced two new cyber security regulations: Unified Requirements (URs) E26 and E27. This will apply to all classed vessels launched from July 2024.

With a goal to increase vessel cyber resilience and safeguard the industry from emerging threats, IACS are making waves in the progression of maritime cyber security and superyacht cyber security in particular. This comes shortly after IASME’s Maritime Cyber Baseline announcement in 2022 alongside other industry standards which placed an increased pressure on the adoption of maritime cyber security across the industry.

Over the course of 2023/24, we will publish articles which help prepare Owners and shipyards for the upcoming regulations to ensure the requirements are included as part of the launch preparation.

What Do UR E26 & E27 Entail?

Both URs build from one another, and they are to be implemented in conjunction. However, there are key differentiators between the two:

UR E26 is a set of guidelines that aims to ensure the secure integration of both Operational Technology (OT) and Information Technology (IT) equipment into the ship’s network during all stages of its life, from design and construction to commissioning and operation. The set of guidelines focuses on the overall cyber resilience of the ship and covers five key aspects: identification, protection, attack detection, response, and recovery.

UR E27 aims to ensure that third-party equipment suppliers secure and strengthen the integrity of on board equipment and systems. This UR gives requirements for the cyber-resilience of systems and equipment on board, as well as more requirements for how users interact with computer-based systems. It also gives requirements for the creation and production of new devices before they can be used.

Why Has IACS Prioritised These New Requirements?

IACS is dedicated to providing safe ships and clean seas, as well as contributing to maritime safety and regulation through technical support, compliance verification, research and development.

Taken from IACS’ website, it is said that “Recognising that cyber incidents on vessels can have a direct and detrimental impact on life, property, and the environment, IACS has steadily increased its focus on the reliability and functional effectiveness of onboard, safety-critical, computer-based systems.  Building on this extensive collaboration, and utilising the experience gained from its existing Recommendations, as well as developments at IMO including, in particular, IMO Resolution MSC.428(98) applicable to in-service vessels since the 1st of Jan 2021, IACS has adopted two new IACS Unified Requirements (URs)”.

Using international standards, such as IEC 62443, the new set of URs establishes industrial automation and control requirements covering the following topics:

  • Scope of applicability, including OT systems for important vessel functions
  • Identification and protection against cyber threats
  • Detection of incidents
  • Means to respond and recover
  • Hardening and security capabilities of systems and components

"These two URs on cyber safety provide minimum goal-based requirements for the cyber resilience of new ships and for the cyber security of onboard systems and equipment. In an increasingly connected and digitised maritime world, these URs represent a significant milestone in IACS’ work to deliver safer shipping in the face of continuously evolving technological developments."

When Will UR E26 & UR E27 Be Implemented?

IACS’ new security focused URs apply to vessels being built on or after the 1st of July 2024.

This date has been selected to allow sufficient time for non-mandatory pilot application of the requirements.  If you would like to get a head start on your compliance and improve your superyacht cyber security, fill out this short form to speak to one of our Cyber Engineers.
