BS ISO 18692-1:2018 specifies the main characteristics and test methods of new fibre ropes used for offshore station keeping.
Fibre ropes for stationkeeping can be manufactured from different rope core material.
BS ISO 18692-1:2018 provides general requirements applicable to all materials. The subsequent parts of the ISO 18692 series provide the specific requirements for each (rope core) material that are not addressed within this document.
4 Materials
4.1 Rope core material
4. 1. 1 Fibre tenacity
The fibre used in the core of the rope shall be in accordance with the specific requirements of each rective part of the ISO 18692 series and shall be qualified and tested according to Annex A.
4.1.2 Marine grade
The fibre used in the core of the rope shall be marine grade fibre. The yarn-on-yarn abrasion
performance shall be verified by tests on wet yarn and it shall meet the requirements of A.4.2.
4. 2 Rope cover material
When polyester yarn is used in the protective cover, it shall be in accordance with Annex A and its minimum tenacity shall be 0,73 N/tex.
5 Requirements- Rope properties
5.1 Minimum breaking strength
The minimum breaking strength of the rope, when tested according to Clause 7 and Annex B, shall conform to specific requirements of each respective part of the ISO 18692 series.
5.2 Minimum core tenacity
The rope minimum core tenacity, measured according to Annex B, shall be in accordance with specific requirements of each respective part of the ISO 18692 series.
5.3 Dynamic stiffness at end of bedding-in
The dynamic stiffness at the end of the bedding-in sequence shall be measured on the prototype testing in step 8 of the rope test procedure in B.3.1.
