Lloyd's Register's Rules and Regulations set appropriate standards for the design, construction and lifetime maintenance of ships, offshore units and land-based installations - providing all the information you need for classification purposes. To keep pace with changes in technology, market trends and new legislation, Lloyd's Register is dedicated to an on-going programme of research and development to enhance existing technical standards and publish new Rules.
How do I access the Rules?
