IACS UR E22(Rev.1) specifies requirements related to composition and function of computer based systems used for machinery systems such as monitoring systems.
These requirements have already been incorporated to Rules and Guidance of NIPPON KAIJI KYOKAI (hereinafter referred as "the Society").
Since the necessity for security measures which reduce risks specific to computer based systems such as computer viruses has been increasing in recent years, IACS discussed way to clarify requirements and adopted UR E22(Rev.2) in June 2016, which specifies responsibilities of stakeholders, security measures for software and hardware and quality management for said systems.
Accordingly, relevant requirements in the Society's Rules and Guidance were amended and what concerned organizations shall address are informed.

1. System Categories
Systems are typically assigned category I, II or III in following Table 2.1 in Annex D18.1.1, Part D of the Guidance for the Survey and Construction for Steel Ships.
