The figure below shows the relationship between this document and other ABS Rules/Guides/Guidance Notes.
This document focuses on design aspect of position mooring systems. Survey requirements remain in relevant Rules/Guides and are referenced in this document.
The design requirements for position mooring systems will be removed from above mentioned Rules/Guides and replaced with references to this document on 1 July 2019.
Before 1 July 2019, designers could choose to use this document or applicable Rules/Guides mentioned above.
On 1 July 2019, the AM Guide and Pre-Laid Guide were withdrawn and only this document remains for the design of position mooring system.
The May 2020 version clarified the requirements for out-of-plane bending analysis in 3/7.5.3 and added requirements for wave-current interaction effects on wave drift force in 8/3.9.2.
The April 2022 version updated the fatigue factor of safety in Section 3, Table 4 to account for out-ofplane bending, in-plane bending, and tension-tension analysis and added a new Subsection 3/11 on temporary operation of mooring systems.
The February 2023 version specifies that Kenter links, pear links, and other temporary mooring connectors are not to be used in permanent mooring systems and provides requirements for connectors to be used in permanent mooring applications.
