SHARE:
PRINT:

This recommended practice focuses on providing a methodology for assessing the risks and required protection from dropped crane loads and ship impact to risers and pipeline systems within the safety zone of installations. Accidental scenarios with other relevant activities such as anchor handling, subsea operations and trawling are also discussed. Where applicable information exists, specific values or calculation procedures are recommended. If no such information is available, then a qualitative approach is given.

The recommended practice is applicable for the following two scenarios:

  • Control that implemented control and protection measures are acceptable.
  • Optimization of planned protection.
