Description: This new publication, the first edition of Recommendations for О/ and Chemical Tanker Manifolds and Associated Equipment supersedes the earlier tides. It takes account of the many years of industry experience with the previous guidance and builds on the earlier recommendations "he following summarises the more significant changes that have been introduced:
• This is now a joint publication with the Chemical Distribution institute (CDI). who have provided valuable input to support the development of recommendations for chemical tankers.
• Guidance has been expanded to include chenwcai tankers and dual classed od/chemicat tankers with the aim of achieving improved compatibility with shore facilities, particularly when these vessels trade to oil terminals.
• The four tonnage categories in the fourth edition of Recommendations for Od Tonker Manifolds and Associated Equipment have been increased to seven. The new table is on page x. The new categories are:
- Two new smaller tonnage categories. These address ships of less than 16,000 tonnes deadweight. The new categories are:
• Category A which covers 5,000 tonnes deadweight or less.
• Category В which covers 5.001 to 16,000 tonnes deadweight.
- The previous tonnage category C. which covered ships of from 60,001 to 160,000 tonnes deadweight, has been divided into two categories. The new categories are:
Category L which coven 60.001 to 120,000 tonnes deadweight Category F which coven 120,001 to 160.000.
