Main contents of the 2022 RCN No.3 of the Rules are as follows:

PART ONE  PROVISIONS OF CLASSIFICATION 

1. Incorporation of IACS Rec.47(Rev.10, 2021.09), adding relevant references and standards in “SHIPBUILDING AND REPAIR QUALITY STANDARD”.

2. Incorporation of class notations of ship communication networks satisfying specific needs and evaluation of collision resistance capability of ships newly added in Chapters 33 and 34 of PART EIGHT of this RCN, as well as class notions added or revised for relevant rules/guidelines effective on or after 1 July 2022, e.g. Rules for Construction and Classification of Sea-Going High Speed Craft (2022 amendments), Rules for Structures of Container Ships, Guidelines for Ships Using Ammonia as Fuel, Guidelines for Ships Using Fuel Cell Power Installations and Guidelines for Ships Using Methyl/Ethyl Alcohol as Fuel.

PART TWO  HULL 

A new Section 8 Energy-saving appendages in front of propellers is added in Chapter 3 Equipment and Outfits, regarding structural strength assessment and welding procedure requirements for energy-saving appendages installed onboard in front of propellers.

PART SIX  FIRE PROTECTION, DETECTION AND EXTINCTION

Incorporation of IACS UR F46 (Aug 2021) Low pressure CO₂ piping system.

PART EIGHT  ADDITIONAL REQUIREMENTS

1. A new Section 33 Ship communication networks satisfying specific needs is added. With regard to specific needs such as passenger using Internet and remote survey, technical requirements for communication networks satisfying specific needs are raised through deployment of ship communication network equipment on board, based on hosting modes of communication networks such as satellite broadband communication network and 4G or 5G cellular communication network.

2. A new Section 34 Evaluation of collision resistance capability of ships is added, giving principled technical requirements for calculation and evaluation of collision resistance capability of structure of sea-going ships, mainly including evaluation method (evaluation conditions, critical deformation energy of side structure, critical striking speed etc.), evaluation criteria and critical striking speed curve.

PART TEN  SHIPS IN RESTRICTED SERVICE

A new paragraph regarding inspection of Watertight Cable Transits is added in “Hull and Equipment Surveys” of Chapter 1 Surveys after Construction of Ships Engaged on Non-International Voyages, by referring detailed inspection requirements to Chapter 5, PART ONE of the Rules.
